NTL No. 2004-N03

Effective Date: July 26, 2004

Notice to Lessees and Operators (NTL) of Federal Oil
and Gas Leases in the Outer Continental Shelf

Directional and Inclination Survey Data Submission Requirements

NOTE: NTL 2004-N03 is available for download in Adobe's Portable Document Format.

This Notice to Lessees and Operators (NTL) is issued pursuant to 30 CFR 250.103 and supersedes Attachment 2 of NTL 2004-G07. It applies to all wells that are spud after the effective date. In this NTL, the Minerals Management Service (MMS) defines the data exchange format on how lessees/operators (you) submit directional surveys required by 30 CFR 250.461, 468, and 469.

Submit to MMS one digital copy and one paper copy of the final composite directional survey. Submit the digital copy on a 3.5” diskette or compact disc using the MMS ASCII, including all header and data items as shown in Attachment 1, “Exchange Format for Directional Surveys.” Make sure that the paper copy contains all the data that are submitted in the digital copy. The header and data records are necessary to ensure complete, accurate wellbore data and will facilitate the use of industry data exchange standards. The table in Attachment 1 shows the Data Type code equivalents (e.g., H0130) for the United Kingdom Offshore Operators Association (UKOOA) Data Exchange Format for Well Deviation Data, P7/2000 Standard.

The MMS collects, verifies, and stores data by the well’s unique 12-digit API number that is assigned by the MMS. The MMS uses the Data collected to make informed regulatory decisions based on your timely submittal of a complete comprehensive package clearly labeled with the appropriate API numbers and contact information.

WellName

A58

Well Name: The name assigned to the well. It may be a special name or the name of the property to which the well belongs. More information and specific details on Well Naming and Numbering Standards can be found in NTL 2000-N07 (e.g., AJ001).

WellNameSuffix

Well Name Suffix: The well name suffix is an extension to the well name which identifies each wellbore and indicates the number of times a well has been sidetracked or bypassed. An 8-character suffix to the well number that identifies a sidetrack (ST) or bypass (BP) and the sidetrack and bypass number (e.g., STNNBPNN). An original hole will have a suffix of ST00BP00, the first sidetrack off the original borehole will have a suffix of ST01BP00, the first bypass off the original borehole will have a suffix of ST00BP01. If the first sidetrack is bypassed, the suffix will be ST01B01. More information and specific details on Well Naming and Numbering Standards can be found in NTL 2000-N07 (e.g., ST00BP01).

UniqueWellIdentifier

A58

API number: A unique well identification number consisting of (left justified) a two-digit state code (or pseudo for Offshore), a three-digit county code (or pseudo for Offshore), a five-digit unique well code and, a two-digit sidetrack code as defined in API Bulletin D12A (e.g., 177561234501).

H0170

ParentWellIdentifier

A58

Parent Well Identifier: The unique well identification number or API number of the borehole that establishes a hierarchy of wellbores. The Parent Well Identifier References the wellbore from which the current wellbore was kicked off. The first ten digits of the 12-digit API Number of the parent wellbore must be equivalent to the subsequent sidetrack or bypass boreholes. The 11^th and 12^th digits will be “00” for the original borehole (e.g., 177671234500).

H0200

GeodeticDatum

West of the zero declination line is negative, East of the zero declination line is positive (e.g., +0.894).

H0520

GridConvergence

F6.3

Grid Convergence: The horizontal angle in (+/-) degrees at a point between true north and grid north. The angle is proportional to the longitude difference between a location and central meridian. Grid convergence is positive east of the central meridian of a projection and negative west of the central meridian (e.g., -1.252).
