Global Framework
• Built on Foundation from “What is a Well?” definitions
• Input from Operators and Information Vendors that
work in U.S., Canada and outside North America
• Current Status and Near Term plans
- Developed first draft of Business Requirements
- Realized more formal Stakeholder Analysis of current practice, issues
and needs is required
- Developed Stakeholder Analysis Interview and Analysis template
- Performing interviews with stakeholders in Q4 2011
• Need additional resources to complete this step, especially for outside U.S.
- Will review and analyze results in early 2012
- Complete first version of Global Framework in Q1 2012

U.S. Well Identification Standard
• After completion of Global Framework, the U.S.
project team will revise API Numbering standard
• API has contracted with PPDM to be steward for the
revised Well Identification and Numbering standard
- Revisions must include practical approaches given legacy practices
• Focus on U.S. Regulatory agencies
- API numbers are set by U.S. regulators in most states
- Project seeks more consistent approach, especially for identification of
all wellbores including pilot holes, mis-steered laterals, junked wellbores
- Stakeholder interviews with Regulatory agencies are happening in next
2 months

Requesting Interviews with Regulatory Agencies
Revising the API Number Standard
• API Number standard last updated 1979
• API has agreed that PPDM is steward of Well
Numbering Standard
• Project team includes operators, regulators, information
vendors
• Issue: Many wellbores are not being identified in
regulatory filings or in regulatory databases
• Lack of information on these wellbores presents issues
for regulators and operators

Original API Process (D12A Standard)
11
Definition: Well vs. Wellbore
Example: One Well with
Two Wellbores
Well: Single surface location and
everything connected to it
Wellbore: Unique path from
surface to bottom hole
12
Example Horizontal Well:
Permit to Drill
Horizontal Well is Proposed.
Exact Depth of Target Zone will
be determined by vertical “Pilot Hole”
13
Example Horizontal Well:
Vertical Pilot Hole
Vertical Pilot Hole is Drilled.
The information from this wellbore is used
to decide the depth of the Lateral
This wellbore is logged and may have
cores and deviation surveys.
14
Example Horizontal Well:
Identify Target Zone
Target Zone for Horizontal is identified
from well logs.
Cement Pilot Hole to kickoff Lateral into
Target Zone
Note: Pilot Hole drills below Target Zone
Cement Plug
Target Zone for Horizontal

15
Example Horizontal Well:
Drill Lateral
Lateral 1 mis-steered below Target Zone.
Operator decides to sidetrack to
position horizontal Lateral in the Target Zone

Example Horizontal Well:
Prepare to Sidetrack

preparation to Sidetrack

Lateral 1: Mis-steer
Example Horizontal Well: “Missing”
Wellbores
Wellbores in Red are not reported
by Operators in many states

Lateral 1: Mis-steer
5 Reasons that Missing Wellbores Matter
21
Why “Missing” Wellbores Matter
1. All wellbores have plugging obligations--not just the
producing wellbore
22
Why “Missing” Wellbores Matter
2. Fluid movement—injected fluids can follow pathway
of any wellbore that open
23
Why “Missing” Wellbores Matter
3. Operators may be required to file information such as
well logs for all wellbores, not just producing
wellbores.

Why “Missing” Wellbores Matter
4. All wellbores must stay within the permitted lease
boundaries and the permitted depths.
Pilot Hole is deeper than the Lateral

25
Why “Missing” Wellbores Matter
5. Anti-collision measures require all wellbores to be
identified and have known paths

GWPC Resolution 11-1 in Support of Project
“BE IT FURTHER RESOLVED that GWPC work with PPDM
Association’s Well Identification Workgroup in its effort to develop
methods for consistently identifying all wellbores in the US.”
27
Asking Regulatory Agencies to Participate
• Our team is interviewing Regulatory Agencies about
current practice and any plans for change
• We will be contacting your agency in next 2 weeks to
set up a 20-minute interview
• PPDM Workgroup will work with IOGCC, GWPC and
Regulatory Agencies to develop practical solutions
- Development of best practices
- Support of PPDM process (revised D12 a)
- Potential model process
Today: Please see Don Drazan NY DEC or Bruce Smith with PPDM
to set up a time for an interview.
Or we will call you in the next 2 weeks to set up a time with your staff
