November 2006POSC Data Management SIG / WIS Work Group8 Current IHS Service POSC SIG June 2006 Master Well Index We will initially populate the MWI with all of the IHS Energy wells in the Canadian, US, and International databases; these will be flagged as proprietary. Over time, we will add to this data on new and unique wells provided to us by customers; these will be flagged as public. New and unique wells added through IHS Energy research and accumulation processes will continue to be flagged as proprietary.

November 2006POSC Data Management SIG / WIS Work Group9 Current IHS Service POSC SIG June 2006 For our customers: We will deliver the full MWI for the regions that they subscribe to. We will deliver records flagged as public for the areas that they don’t subscribe to. The proprietary content of the MWI will remain the property of IHS Energy covered by existing data contracts.

Business Case Template for Support of Global Unique Well Identifier Use by Operators Work-in-Progress by Mark Stehm, ExxonMobil Kris Gibbons, Shell

November 2006POSC Data Management SIG / WIS Work Group18 Sample Template  Business Case Some companies, maybe all, will want a business case documented for the use of the industry standard GUWIs in their database(s) and business transactions The purpose of this template is to help get started on that business case document You can use as much or as little of it as you need The final document will be available at

November 2006POSC Data Management SIG / WIS Work Group19

November 2006POSC Data Management SIG / WIS Work Group20 Introduction POSC ~ IHS ~ GUWI ~ Services Purpose of “Identifier” –Single source for a unique code that can be used by all operators, service companies and data providers to tag information for delivery to a customer. –This will facilitate matching data from multiple sources –This will reduce the likelihood of errors  improved performance and data quality

November 2006POSC Data Management SIG / WIS Work Group21 Table of Contents Background Process Investment Risks Benefits Appendix: Data Elements

November 2006POSC Data Management SIG / WIS Work Group22 Background Problem –~ 4 million oil and gas wells, world-wide. –Status: from very old P&A through active producers / injectors to currently drilling wells. –Regulatory agencies assign well id/names. –Id/names change due to Sales Unitization Life cycle changes Etc.

November 2006POSC Data Management SIG / WIS Work Group23 Background Problem (continued) –Difficult to merge well data –Difficult to merge or compare data from multiple sources –DM staff and geoscientists & engineers must perform matching process to make use of data –Matching can occur multiple times over the life of a well –The challenge of matching may prevent the most current data from being loaded and made available –Manual matching wastes time and money

November 2006POSC Data Management SIG / WIS Work Group24 Background Solution –Single identifier –Assigned in a consistent manner –By one service –For every well in existence Condition of Success –Use of the GUWI must become wide-spread to achieve automated matching of well data from multiple sources. Result –More efficient and consistent transfers within the operator’s organization, with partners, with service companies, with regulators.

November 2006POSC Data Management SIG / WIS Work Group25 Process Current Wells –Operator is responsible for the well data Knows the quality of the data –Operator provides mandatory data element values to the Registration Service –Registration Service assigns GUWI and provides GUWI to Operator. Data stored in Public Well Index file, available to industry –TIGHT WELL PROVISION. Operator may declare well as ‘tight’ up to a designated date. –NON-PUBLIC PROVISION. Operator need not declare well data “public.” Any data element values given to Service Provided kept as proprietary.

November 2006POSC Data Management SIG / WIS Work Group26 Process Legacy Data –For older wells, any industry company may send data element values to Matching Service. Match OK. Existing GUWI returned. Match Not-OK. Operator may use Registration Service … –If Operator sends data for matching, data element values may be added to Public Well Index. –NON PUBLIC PROVISION. Operator need not declare well data “public.” Any data element values given to Service Provided kept as proprietary. –TRANSPARENCY. Matching Service Provider will not retain data element values used only for matching purposes.

November 2006POSC Data Management SIG / WIS Work Group27 Investment Cash Costs –Retail use of Services No fees if within usage limits (to be defined) May be fees if bundled with value-added competitive services, e.g. subscription services –Payments to Service Provider to offset cost of delivering industry Standards-related Services Managing Public Well Index Registration Service Matching Service –Funding From WIS Work Group Sponsor Members Separate from POSC dues and SIG fees

November 2006POSC Data Management SIG / WIS Work Group28 Investment Manpower –Cost of initial implementation –Software to retrieve Operator data to be sent to Service Provider for Registration &/or Matching Initial format is a spreadsheet Task time: few days including exception handling –Ongoing cost to interact with Service Provider –Summary Few days programming and data management (once) Monitoring on an ongoing basis

November 2006POSC Data Management SIG / WIS Work Group29 Risks Release of Information –Must avoid pre-mature release of information. –Options: Do not register Do not provide data element values to Service Provider (as Public Data or otherwise) Declare well to be ‘TIGHT’ for a period of time Government Data Release Rules –Restricted countries –Automatic release after “x” time countries

November 2006POSC Data Management SIG / WIS Work Group30 Benefits Overview –Operators use data from many sources for prospecting and surveillance. –Manual involvement in matching data is time consuming and costly, regardless of which type of employee does the work –Time delays in matching processes can have negative impact of performance

November 2006POSC Data Management SIG / WIS Work Group31 Benefits Actual Savings –Example. Consider 200 project data stores containing 100,000 wells. One data vendor provides updates weekly. –5% matches need manual reconciliation –5 minutes each Intervention cost = 400+ man-hours per week or 10+ full-time employees. –Example. [Look for other examples that impact positive results rather than cost savings.]
