Are we progressing? Oil & Gas Data Management Journey…

Last month, I had dinner with a long-term friend who is now part of a team that sets strategic technical plans for his E&P employer. Setting strategies requires a standardized view of technical & financial data across all assets, in this case, multinational assets around the world. This data is required at both granular and helicopter level.  One of the things he mentioned was “I have to start by fixing data standards. I am surprised how little progress data-management standards have made since the POSC days in the mid 90s.”

How did Data Management evolve in oil & gas? Are we repeating mistakes? Are we making any progress? Here is what my oil and gas friends and I remember in this first part of a three-part series.  Please join me on this journey down memory lane and add your own thoughts.

The 1960s & 70s

Perhaps we can call these times, mainframe times.  Mainframes started to make their way into our industry around the mid-60s. At that time, they were mostly used to maintain accounting data. Like most data at this time, E&P accounting data was manually entered into systems, and companies employed large data-entry staff to input. Any computational requirement of the data was through feeding  programs through “punch cards”.

Wireline logs (together with Seismic data) were one of the very first technical data that required the use of computers, mainly at the service provider’s Computer Centers and then at the large offices of the largest major operators. A friend of mine at Schlumberger remembers the first log data processing center in Houston opening about 1970. In the mid-70’s more oil city offices (Midland, Oklahoma City, etc.) established regional computing centers. Here, wireline log data, including petrophysical and geological processing, was “translated” from films into paper log graphics for clients.

A geophysicist friend remembers using mainframe computers to read seismic tapes in the mid-70s. He said, “Everything was scheduled. I would submit my job, consisting of data and many Punch Cards, into boxes to get the output I needed to start my interpretation. That output could be anything from big roll of papers for seismic sections to an assemblage of data that could then be plotted. Jobs that took 4 hours  to process on a mainframe in the 70’s are instantaneous today”

The Society of Exploration Geophysicist (SEG) introduced and published data formatting standard SEG_Y in 1975.  SEG-Y formats are still utilized today.

The need to use a standard, well number identification process became apparent as early as 1956. Regulatory agencies started assigning API numbers to wells in the late 60s in the USA. The concept of developing world wide global well ID numbers is still being discussed today with some organizations making good progress.

The 2nd half of the 70s, pocket calculators and mini computers made their way to the industry. With that some computations could be done at the office or on the logging truck at the field without the need for Mainframes.

The 1980s

Early 80s. With the proven success of 3D seismic introduced by ExxonMobil, large and special projects started heavily processing 3D seismic on Mainframes. However, the majority of technical data was still mainly on paper. Wireline logs were still printed on paper for petrophysicists  to add their handwritten interpretations. Subsurface maps were still drawn, contoured and colored by hand. Engineering data came in from the field on paper and was then recorded on a running paper table. A reservoir engineer remembers   “We hired data clerks to read field paper forms and write the data in table (also on paper)”.

As personal computers  (PCs) made their way into the industry, some large companies started experimenting,  albeit they lacked the personal side since PCs were numbered and located in a common area. Employees were only given occasional access to them. These were also standalone computers, not networked. Data transfer from one PC to another happened via floppy disk. It was during this time that engineers were first exposed to spreadsheets (boy did they love those spreadsheets! I know I do)

Mid-80s. March 1986, oil prices crashed, a 55% drop over few days. In the three years following the crash, the industry shed staff the way cats shed hair. The number of petroleum staff dropped from approximately 1,000,000 employed staff to approximately 500,000 in three years.

oil price

Late 80s. But what seemed bad for the industry, may have also done the industry a favor. The oil price crash may have actually accelerated the adoption of technology. With a lot less staff, companies were looking for ways to accomplish more with less staff.

A geologist friend remembers using Zmap as early as 1988, which was the beginning of the move towards predominantly computer-based maps and technical data.

For data nerds: 

  • Engineers and geo professionals were responsible for maintaining their own data in their offices.
  • Although not very formal, copies of the data were maintained in centralized “physical” libraries. Data was very important in the “heat of the moment” after the project is complete, that data is someone else’s issue. Except there was no “someone else” yet.
  • This system produced many, many versions of the same data (or a little variation of it) all over. This data was predominantly kept on physical media and some kept on floppy disks which were mostly maintained by individuals.
  • From the 60s through to the end of the 80s, we can say there were mostly two global standards, one for the seismic data formatting – SEG-Y – and the other for log data – LAS (Log Ascii Standard). Any other standards were country- or company-specific.

I would love to hear from you if you feel I have missed anything or if you can add to our knowledge of how technical E&P data was managed during the above period.

Stay tuned for the 90s …

Data and Processes are your two friends in fat or skinny margin times – Some tools and ideas to weather low oil-prices

well;  2014 is ending with oil prices down and an upward trend on M&A activities. For those that are nearing retirement age, this is not all bad news. For those of us that are still building our careers and companies, well, we have uncertain times ahead of us. This got me asking: is it a double whammy to have most knowledgeable staff retiring when oil prices are low? I think it is.

At the very least, companies will no longer have the “fat margins” to forgive errors or to sweep costly mistakes under the rug! While costs must be watched closely, with the right experience some costs can be avoided all together. This experience is about to retire.

For those E&P companies that have already invested (or are investing) in putting in place, the right data and processes that captured knowledge into their analysis and opportunity prioritization, will be better equipped to weather low prices.  On the other hand, companies that have been making money “despite themselves” will be living on their savings hoping to weather the storm. If the storm stays too long or is too strong they will not survive.

Controlling cost the right way

Blanket cost cutting, across all projects is not good business. For example some wells do not withstand shutting down or differing repairs, you would risk losing the wells altogether. Selectively prioritizing capital and operational costs with higher margins and controllable risks, however, is good business. To support this good business practice is a robust foundation of systems, processes and data practices that empower a company to watch important matrices and act fast!

We also argue that without relevant experience some opportunities may not be recognized or fully realized.

Here are some good tools to weather these low prices:

Note that this is a quick list of things that you can do “NOW” for just few tens or few hundred thousand dollars (rather than the million dollar projects that may not be agile at these times)

  •  If you do not have this already, consider implementing a system that will give you a 360 degree view of your operations and capital projects. Systems like these need to have the capability to bring data from various data systems, including spreadsheets. We love the OVS solutions (http://ovsgroup.com/ ). It is lean, comes with good processes right out of the box and can be implanted to get you up and running within 90 days.
  • When integrating systems you may need some data cleaning. Don’t let that deter you; in less than few weeks you can get some data cleaned. Companies like us, Certisinc.com, will take thousands of records validate, de-duplicate, correct errors, complete what is missing and give you a pristine set. So consider outsourcing data cleaning efforts. By outsourcing you can have 20 maybe 40 data admins to go through thousands of records in a matter of a few days.
  • Weave the about-to-retire knowledge into your processes before it is too late. Basically understand their workflow and decision making process, take what is good, and implement it into systems, processes and automated workflows. It takes a bit of time to discover them and put them in place. But now is the time to do it. Examples are: ESP surveillance, Well failure diagnosis, identifying sweet frac’ing spots…etc. There are thousands upon thousands of workflows that can be implemented to forge almost error proof procedures for  “new-on-the job” staff
  • Many of your resources are retiring, consider hiring retirees, but if they would rather be on the beach than sitting around the office after 35+ years of work; then leverage systems like OGmentorsTM (http://youtu.be/9nlI6tU9asc ).

In short, the importance of timely and efficient access to right & complete data, and the right knowledge weaved into systems and processes are just as important, if not more important, during skinny margin times.

Good luck. I wish you all Happy Holidays and a Happy 2015.

A master’s degree in Petroleum Data Management?

I had dinner with one of the VPs of a major E&P company last week. One of the hot topics on the table was about universities agreeing to offer MSc in Petroleum Data Management. Great idea!  I thought. But it brought so many questions to my mind.

 

Considering where our industry is with information management (way behind many other industries), I asked who will define the syllabus for this PDM MSc? The majors? The service companies? Small independents? Boutique specialized service providers? IMS professors? All of the above?

 

Should we allow ourselves to be swayed by the majors and giant service companies? With their funding they certainly have the capability to influence the direction, but is this the correct (or only) direction? I can think of few areas where majors implementation of DM would be an overkill for small independents, they would get bogged down with processes that make it difficult to be agile! The reason that made the independents successful with the unconventional.

 

What should the prerequisite be? A science degree? Any science degree? Is a degree required at all? I know at least couple exceptional managers, managing data management projects and setting up DM from scratch for oil and gas companies, they manage billions of dollars’ worth of data. They do not have a degree, what happens to them?

 

It takes technology to manage the data.  MSc in Petroleum Data Management is no different. But unlike petroleum engineering and geoscience technologies, technology to manage data progresses fast, what is valid today may not still be valid next year! Are we going to teach technology or are we teaching about Oil and Gas data? This is an easy one, at least in my mind it is, we need both. But more about the data itself and how it is used to help operators and their partners be safer, find more and grow. We should encourage innovation to support what companies need.

 

PPDM – http://www.ppdm.org/ is still trying to define some standards, POSC (Petrochemical Open Standards Consortium (I think that is what it stands for, but not sure) came and went, Energistics – http://www.energistics.org/ is here and is making a dent, Openspirit – http://www.tibco.com/industries/oil-gas/openspirit made a dent but is no longer non-profit. Will there be standards that are endorsed by the universities?

The variations from company to company in how data management is implemented today is large. Studying and comparing the different variations will make a good thesis I think…

I am quite excited about the potential of this program and will be watching developments with interest.

 

E&P Companies Looking to New Ways to Deliver Data Management Services to Improve efficiency and transparency

Effective data management, specifically in the exploration and production (E&P) business, has a significant positive impact on operational efficiency and profitability of oil and gas companies. Upstream companies are now realizing that a separate “Data Management” or “Data Services” department is needed in addition to the conventional IT department. Those Departments’ key responsibilities are to “professionally” and “effectively” manage E&P technical data assets worth millions, in some cases, billions of dollars.

Traditional Data Management Processes Cannot Keep up with Today’s Industry Information Flow 

Currently, day-to-day “data management” tasks in the oil and gas industry are directed and partially tracked using Excel spreadsheets, emails and phone calls. One of the companies I visited last month, was using excel to validate receipt of seismic data against contracts and PO; e.g. all surveys and all their associated data. Another one used excel to maintain a list of all Wire-line Log data ordered by petrophysicists in a month to compare to end-of-the-month invoices.

Excel might be adequate if an E&P company is small and has little ambition to grow. However, the larger a company’s capital (and ambitions) the more information and processes are involved to manage data and documents’ life cycle. Consider more than 20,000 drilling permits issued a year in Texas alone. Trying to manage this much information with a spreadsheet, some tasks are bound to fall through the cracks.

Senior managers are more interested than ever in the source , integrity and accuracy of information that affect and influence their HSE and financial statements.
Providing senior managers with such information requires transparent data management processes that are clearly defined, repeatable, verifiable and that  allow managers to identify, evaluate and address or alleviate any obvious or potential risks…. before they become a risk. Preferably all delivered efficiently and cost-effectively.

Choosing the Right E&P Data Management Workflow Tools

It’s tempting to stay with the old way of doing things – the “way we have always done it” – because you have already established a certain (and personal), rhythm of working, inputting and managing data. Even the promise of improved profitability and efficiency is often not enough to convince people to try something new. But the advantages of new workflow tools and programs cannot and should not be underestimated.

For example, a workflow tool can help automate the creation of data management tasks, log and document technical meta data,  track data related correspondence, alert you for brewing issues. When all set and done, data management department would be set for growth and for handling more load of work with out skipping a beat.  Growing by adding more people is not sustainable.

So, where to start?

There are multiple data management workflow tools available from a variety of different vendors, so how do you know which one will work best for your company? You will need to ensure that your workflow tool or software is able to do the following:

  • Keep detailed technical documentation of incoming data from vendors, thereby minimizing duplication of work associated with “cataloging” or “tagging”;
  • Integrate with other systems in your organizations such as Seismic, Contracts, Accounting…etc., including proprietary software programs;
  • Allow sharing of tasks between data managers;
  • Enable collaboration and discussion to minimize scattered email correspondence; and,
  • Automatically alert others of issues such as requests that still need to be addressed

 

 

Change Coming Our Way, Prepare Data Systems to Store Lateral’s Details.

Effectively, during the past decade, oil and gas companies have aimed their spotlight on efficiency. But should this efficiency be at the expense of data collection? Many companies are now realizing that it shouldn’t.

Consider the increasingly important re-fracturing effort.  It turns out, in at least one area, that only 45% of re-fracs were considered successful if the candidates were selected using production data alone.  However, if additional information (such as detailed completion, production, well integrity and reservoir characterization data) were also used a success rate of 80% was observed. See the snip below from the Society of Petroleum Engineer’s paper “SPE 134330” by M.C Vincent 2010).

Capture

Prepare data systems to store details, otherwise left in files.

Measurements while drilling (MWD), mud log – cuttings analysis and granular frac data are some of the data that can be collected without changing drilling or completion operations workflow and the achieved efficiency.  This information when acquired at the field will make its way to petrophysicists and engineers. Most likely it ends up in reports, folders and project databases.  Many companies do not think of this data storage beyond that.

We argue, however, to take advantage of this opportunity archival databases should also be expanded to store this information in a structured manner. This information should also funnel its way to various analytical tools. This practice will allow technical experts to dive straight into analyzing the wells  data instead of diverting a large portion of their time in looking for and piecing data together. Selecting the best re-frac candidates in a field will require the above well data and then some. Many companies are starting to study those opportunities.

Good data practices to consider

To maximize economic success from re-stimulation (or from first stimulation for that matter) consider these steps that are often overlooked:

  1. Prepare archival databases to specifically capture and retain data from lateral portions of wells. This data may include cuttings analysis, Mud log analysis, rock mechanics analysis, rock properties, granular frac data, and well integrity data.
  2. Don’t stop at archiving the data, but expose it to engineers and readily accessible to statistical and Artificial Intelligence tools. One of those tools is Tibco Spotfire.
  3. Integrate, integrate, integrate. Engineers depend on ALL data sources; internal, partners, third party, latest researches and media, to find new correlations and possibilities. Analytic platforms that can bring together a variety of data sources and types should be made available. Consider Big Data Platforms.
  4. Clean, complete and accurate data will integrate well. If you are not there yet, get a company that will clean data for you.

Quality and granular well data is the cornerstone to increasing re-frac success in horizontal wells and in other processes as well.  Collecting data and managing it well, even if you do not need it immediately, is an exercise of discipline but it is also a strategic decision that must be made and committed to from top down. Whether you are drilling to “flip” or you are developing for a long term. Data is your asset.

 

Capture The Retiring Knowledge

The massive knowledge that is retiring and about to retire in the next five years will bring some companies to a new low in productivity. The U.S. Bureau of Labor Statistics reported that 60% of job openings from 2010 to 2020 across all industries will result from retirees leaving the workforce, and it’s estimated that up to half of the current oil & gas workforce could retire in the next five to ten years.

For companies that do not have their processes defined and weaved into their everyday culture and systems — relying on their engineers and geoscientists knowledge instead — retirement of these professionals will cause a ‘brain drain,’ potentially costing these companies real down time and real money.

One way to minimize the impact of “Brain Drain” is by documenting a company’s unique technical processes and weaving them into training programs and, where possible, into automating technology. Why are process flows important to document? Process flow maps and documents are the geographical maps that give new employees the direction and the transparency they need, not only to ramp up a learning curve faster, but also to repeat the success that experienced resources deliver with their eyes closed.

For example, if a reservoir engineer decides to commission a transient test, equipment must be transported to location, the well is shut down and penetrated, pressure buildup is measured, data is interpreted, and BHP is extrapolated and Kh is calculated.
The above transient test process, if well mapped, would consist of: 1) Decisions 2) Tasks/ Activities 3) A Sequence Flow 4) Responsible and Accountable Parties 5) Clear Input and Output 6) and Possible Reference Materials and Safety Rules. These process components, when well documented and defined, allow a relatively new engineer to easily run the operation from start to end without downtime.

When documenting this knowledge, some of the rules will make its way in contracts and sometimes in technology enablers, such as software and workflow applications. The retiring knowledge can easily be weaved into the rules, reference materials, the sequence flow, and in information systems.

Documenting technical processes is one of the tools to minimize the impact of a retiring workforce. Another equally important way to capture and preserve knowledge is to ensure that data in personal network drives is accumulated, merged with mainstream information, and put in context early enough for the retiring workforce to verify its accuracy before they leave.

Processes and data  for a company make the foundation of a competitive edge, cuts back on rework and errors, and helps for quickly identifying new opportunities.

Better Capital Allocation With A Rear-View Mirror – Look Back

In front of you are two choices: Tie up $100 million with low return or over spend by $50 million with no reliable return. Which option do you choose? Neither is acceptable.

“It seemed we were either tying up cash and missing on other opportunities, or overspending where we should not have in the first place,” said a former officer of a US independent. “We heard great stories at presentations from engineers and geoscientists as they were painting the picture to executives to fund their programs. But at the end of the year, the growth was never where we had expected it to be.”

Passing by poor investments through better allocation of capital greatly enhances company performance. To achieve this, executives needed a system to look back and evaluate what each asset team had predicted compared to the actual performance of the asset. They needed a look-back system where hindsight is always 20/20.

A look-back system is beneficial not only for better capital allocation, but also to identify and understand the reasons for low or high performance of an investment.

Implementing a look-back system is data intensive. The data needed, however, typically has already been collected and stored as part of everyday operations. For example most companies have an AFE system that captures predicted economics of well projects. All companies keep system(s) to capture production volumes and accounting data for both revenue and costs.  Data for evaluating an investment after-the-fact is already available – for the most part.  The reason executives did not have a look-back system was buried in their processes. In how each asset’s economic returns are calculated and allocated.

Here are few tips to consider when implementing a look-back system for an oil and gas company:

  • Start with the end. Identify the performance indicators (KPI) required to measure assets’ performance.
  • Standardize how economics are prepared by each asset team. Only then will you be able to compare apples to apples.
  • Allocate costs and revenue back to each well. Granularity matters and is key. With granularity, mistakes of lumping costs under a wrong category can be avoided and easily rectified.
  • Missing information for the KPI’s? Introduce processes to capture and enter data in company’s systems (historically this information may be in presentation slides and personal spreadsheets).
  • If well information is scattered across systems, data integration will be needed. Well, AFE, Production, Reserves, and Accounting data will need to be correlated.
  • Automate the generation of information to executives. Engineers and geoscientist should not have to prepare reports at the end of each month or quarter to management. Their time is FAR better spent making money and assets work harder for their investors.
  • Know it is a change to the culture. Leadership support must be behind the initiative and well communicated throughout the stake holders.

“Once we implemented a look-back system, we funded successful teams more and reduced the budget from under performing assets, then we utilized the freed money to grow. We were a better company all around” – Former Officer of a Large Independent.
