1 PROFESSIONAL PETROLEUM DATA MANAGEMENT ASSOCIATION Canadian Well Identification Revision Project Overview PPDM Quarterly Luncheon Wednesday April 24 th, 2013 Jeffrey Bonus, B.Sc., PMP

2 PROJECT WORK GROUP The Project Work Group is made up of: 16 Companies Apache, Baker Hughes, BP, CAPP, Cenovus, Chevron, Conoco Phillips, Devon, Encana, geologic, IHS, Lumina, Nexen, Shell, Talisman, XI Technologies Inc. 5 Regulators British Columbia, Alberta, Saskatchewan, Manitoba, Nova Scotia 2

3 WHAT IS A WELL? The following terms are based on the What is a Well definitions (see booklet): Well Well Origin Wellbore Wellbore Completion 3

4 DISCLAIMER This is an update on an active project. Completion Date June 2013 The concepts in the following slides are proposed and will be provided to the Regulators in a Position Paper from the Work Group on June 1 st These concepts could change. 4

5 WHY REVISE? Quantity of changes with UWI not permanent UWI is being used as a Primary Key Too much embedded information in UWI UWI in Alberta can only handle 9 events Not all wellbores and wellbore completions being identified UWI is a well event identifier, not a well identifier UWI identifies the bottom hole Overloaded Positions Location Exception (positions 2-3) overloaded - Second (or more) well in same LSD - Road allowance location - Alberta resource types oil sands evaluation, water, coal, etc. Event Sequence (positions 16 or 15-16) overloaded - Licence event, drilling event, completion event - ERCB considering moving from 16 only to

6 BUSINESS REQUIREMENTS Need a Well identifier Need a unique and permanent identifier Need to identify the jurisdiction i.e. province Need to uniquely identify a Wellbore Need to uniquely identify a Wellbore Completion Need to tie Wellbores to the Well Need to tie Completions to the Well 6

7 UWI RECOMMENDED CHANGES Recommend changing the Location Exception Code to two static characters for sequence only (00-99, AA-ZZ), no embedded meaning. Recommend that the ERCB add the 15th character back into their systems and use for the event sequence to allow for 99 events 7 DRAFT

8 NEW IDENTIFIERS Logical Diagram Well ID Wellbore ID Drilling or Cancelled UWI Other attributes etc. Wellbore Completion ID Producing/Completion UWI Other attributes etc. Other attributes etc. 8 DRAFT

9 GUIDING PRINCIPLES FOR WELL, WELLBORE AND WELLBORE COMPLETION IDS Every ID is unique. Every ID is permanent. Every ID from the Primary Assigning Authority supersedes any other identifier in public circulation. The IDs should not enforce a time sequence (drilling, approval, issue, etc.). The value of the ID implies no temporal order or meaning. 9 DRAFT

10 GUIDING PRINCIPLES FOR WELL IDS Every Well has a Well ID. Every physical Well Origin has one and only one Well ID. Re-entry into the same Well Origin has the same Well ID as the existing well. 10 DRAFT Copyright 2013 PPDM Association. All Rights Reserved

11 GUIDING PRINCIPLES FOR WELLBORE IDS Every Wellbore has a Wellbore ID Every Wellbore has a drilling or cancelled UWI Every Wellbore is associated with one and only one Well ID 11 DRAFT

12 GUIDING PRINCIPLES FOR WELLBORE COMPLETION IDS Every Wellbore Completion has a Wellbore Completion ID Every Wellbore Completion has a producing / completion UWI Every Wellbore Completion is associated with one and only one Well ID 12 DRAFT

13 WELL ID The Well Identifier is comprised of two semantic parts. Province / Territory code Well code E.g. AB Positions: Name: Province / Territory Well Example: AB DRAFT

14 WELLBORE ID The Wellbore Identifier is comprised of three semantic parts. Well ID Component Type Component Value E.g. AB B001 Positions: Name: Well ID Component Type Component Value Example: AB B DRAFT

15 WELLBORE COMPLETION The Wellbore Completion Identifier is comprised of three semantic parts. Well ID Component Type Component Value E.g. AB C001 Positions: Name: Well ID Component Type Component Value Example: AB C DRAFT

16 NEXT STEPS Write Position Paper for Regulators Due June 1 st 2013 Write Standard for new identifiers In progress Available for review in May Update UWI standard TBD 16
