Who assigns API numbers for new wells?
Regulatory agencies Information providers
Operators
Each organization uses different information to assign API numbers.
Each organization uses different numbering approaches.
Result: You cannot connect data using API numbers and expect
information from different sources to all tie together correctly.

Who assigns API numbers?
Regulatory agencies Most states assign only 10 digits of API number to Well Origin A few states assign 11-12th digits for wellbore identification 2 states assign 13-14th digits for well events Numerous states use 11-14th digits in conflict w/ D12A standard
Result: If you mix API numbers from state agencies with API numbersfrom other sources you are almost certain to have a significant numberof incorrectly integrated data

Who assigns API numbers?
Information providers Assign 10-digit API number for states without API numbers Often assign 11-12th digit for wellbores
Some increment only for wellbores to geologic target Some increment for any wellbore, whether to target or not
Some providers assign 13-14th
digit for well events Deepenings
Recompletions
Re-entry to plugged well
Different providers have different rules for when API numbers
should be changed API changes are a major source of industry frustration

Examples of Information Used for AssigningAPI number
Regulators work from permit information
Vendors use different sources Sources of information vary by state, by confidentialityperiod, by operator reporting practices, by state releasepractice
Regulatory forms: permits, drilling, completion
Supporting documents w/ forms: wellbore diagrams
Well measurements: logs, directional surveys
Operators use well logs, directional surveys,internal sources to identify wellbores

Example of Pilot Hole in TX 42-123-32202
Eagleford Shale horizontal well
Nothing on Permit about pilot hole Possibly pilot hole in supporting docs for permit?
Nothing on filed directional survey
G-1 Test Report mentions sidetrack at xxxx Well logs may indicate pilot hole
Well logs for each wellbore?
Log indicates near-vertical section at depths where Operator
filings with RRC indicate well is horizontal?

Wellbore diagrams can tell the story
Why not work with regulators so this type ofdiagram is filed in all states?
