DOCD
A Development Operations Coordination Document (DOCD) is a plan that describes development and production activities proposed by an operator for a lease or group of leases. The description includes the timing of these activities, information concerning drilling vessels, the location of each proposed well or production platform or other structure, and an analysis of both offshore and onshore impacts that may occur as a result of the plans implementation.
A Supplemental DOCD describes proposed activities on a lease(s) that were not included in a previously approved DOCD and will require approval of additional permit(s).
A Revised DOCD describes changes to the proposed activities included in a previously approved DOCD, but will not require the approval of additional permit(s).
Exploration Plan
An Initial Exploration Plan describes all exploration activities planned by an operator for a specific lease(s), the timing of these activities, information concerning drilling vessels, the location of each well, and an analysis of both offshore and onshore impacts that may occur as a result of the plan's implementation.
A Supplemental Exploration Plan includes a description of proposed activities on a lease(s) that were not included an original Exploration Plan for that lease(s).
A Revised Exploration Plan describes changes to proposed activities already included in a previously approved Exploration Plan.
APM
An Application for Permit to Modify is an application to conduct workover, completion, abandonment or any other non-routine operations.
A Revised Application for Permit to Modify involves a change to a previously approved Application for Permit to Modify.
A revision to a sidetrack involves a change to the drilling of a sidetrack from an existing well, which may be necessary for safety purposes, such as if an operator determines it necessary to set a liner deeper in the wellbore due to results from a formation integrity test.
New Well
A new well involves an operator drilling an original wellbore hole in the seafloor to a geologic target.
A revision to a new well involves a change to the drilling of new well, which may be necessary for safety purposes, such as if an operator determines it necessary to set a liner deeper in the wellbore due to results from a formation integrity test.
Sidetrack
A sidetrack involves an operator drilling to a new geologic target or a new location within the original target from an existing wellbore.
A revision to a bypass involves a change to the drilling of a bypass from an existing well, which may be necessary for safety purposes, such as if an operator determines it necessary to set a liner deeper in the wellbore due to results from a formation integrity test.
Bypass
A bypass is when an operator drills around a mechanical problem in the original hole to the original target from the existing wellbore.
