EXCHANGE FORMAT FOR DIRECTIONAL SURVEYS
An example of a complete MMS ASCII file is shown
Attachment 2. The first column in the table below represents the equivalent
header type codes and column numbers for the UKOOA P7/2000 data exchange
format for well deviation data for format comparison. The MMS Type codes
cover columns 1-5, the MMS Item name cover columns 7-41, and the MMS format
statements begin in column 43 and end in column 130 with no leading spaces.
MMS has added the following cards: “H0112 WellNameSuffix”, “H0114
BottomHoleLeaseNumber”, “H0624 TieinMeasuredDepth” and “H00625
TieinTotalVerticalDepth”. The format description is given in FORTRAN
style (i.e. F-float, A-character, I-integer, X-space). Example (A4, 2X,
F6.3) = ABCD 11.111.

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). |

Card |
WellNameSuffix |
A8 |
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). |
