3 Sub Mnemonics

Tool strings are constructed by joining together individual items of downhole

equipment known as subs. Measurement subs may be complete tools or part of tools,

whilst non-measurement subs link other subs together, or may be used to achieve some

desirable geometrical configuration.

In some cases, the same type of measurement sub may be used in more than one tool

(an example being the Borehole Geometry Navigation Sub used in the Precision Strata

Dipmeter and Acoustic Scanning Tool).

Each sub has a unique mnemonic. The Downhole Configuration Diagram printed on

logs acquired with SS1 software shows the subs that make up each tool string, and their

mnemonics are listed in the Tool Table part of an LIS file.

3.1 Measurement Subs

These are listed alphabetically. In some cases, tools are made up of a single sub.

Where this is not the case, the associated list of tools indicates where the subs are used.

4 Curve Mnemonics - by Tool

This section contains a comprehensive list of curve names associated with each tool-

type. The curve description is that which appears on the log header (some

abbreviations have been expanded).

A Sub List is provided for those tools supported by SS1 data acquisition software; the

list provides information needed to validate certain styles of LIS file (see Section 5).

The List identifies the particular sub from which a measurement originates. Multiple

entries mean that the same measurement is made by more than one sub; no entry for

an SS1 supported tool means that the corresponding curve is part of a private status

channel or has been generated at the surface.

The curve lists for Compact (M-Series) tools refer to data acquired with the Windows

Logging Software after March 1999.

6 LIS Format Mnemonics

The LIS file format is the most widely used exchange format for log data. Customer

files generated to the LIS format involve a transcription from the Reeves proprietary

storage format used during acquisition and processing.

During transcription, standard LIS curve mnemonics will normally be substituted for

Reeves mnemonics whenever there is generic equivalence. For example, the generic

LIS mnemonic GR replaces Gamma Ray curves. If there is no generic equivalent, the

Reeves mnemonic is retained.

Some LIS reading systems (Log Base from Schlumberger and Pagoda developed by

Schlumberger for Shell) incorporate a curve validation capability which uses a database

of service company - specific mnemonics. In particular, they cross check the list of

subs contained in the optional Tool Table part of the LIS file with the list of curves

contained in the log data part of the file.

LIS files generated to this standard use Reeves mnemonics only i.e. no substitutions

take place.

For open hole data acquired with SS1 software, the mnemonics listed in Section 3 and

4 allow proper validations.

For production logging data, and for data acquired with software other than SS1

software, some additional cross-referencing information is required.

Production Logging Suite Subs & Curve Mnemonics Cross Reference

The following table identifies the measurement subs from which individual curves

originate. Refer to Section 4 for the curve description. Note that some measurements

are present on more than one sub.

The Production Logging curves HORN, LSPD, PERF, TIMP and TPRD originate at

the surface and may be associated with any sub.

Data Acquired With Software Other Than SS1

Most open hole data are acquired with SS1 software. It permits tool strings to be

configured using any of the supported sondes, and contains a database of subs from

which information is extracted for inclusion into the Tool Table part of an LIS file.

Tools that are not supported by SS1 software have their data acquired by tool or

combination-specific software systems. Each system has a unique Software Service

Name. In these cases the Software Service Name is substituted for the physical tool

names in the LIS Tool Table.


The following list of Software Service Names are those that are currently supported.

Software Services Name Description

BTV AST acquisition

CCL analogue GCL acquisition

FDH MBD acquisition

FDR PSD acquisition with real time dip computation

FDX PSD and BGS acquisition without real time dips

LSS LCS acquisition, waveform mode

RFS RFS acquisition

SNC CBL acquisition using the CNS sub from the NCS tool

SPD CBL acquisition using the CNS sub from the PDS tool

TDS TDS acquisition

The following is a list of Software Service Names that are no longer supported, but

which may be present in older data sets.

Software Service Names & Curve Mnemonics Cross Referencing

Not all the curve names listed in Section 4 are supported by current non-SS1 software.

BTV, CCL, FDH, RFS and TDS software systems do support all curves given for their

associated tools. FDR, FDX, LSS, NC1, SNC and SPD support a sub-set of curves

from the associated tools. This must be taken into account if curve names are to be

validated against Software Service Names.

The FDR software system supports all Precision Strata Dipmeter curves except AREF,

BRKT, CAXR, CAYR, RBHS, TDEP and TFDS.

The FDX software system supports all Precision Strata Dipmeter Curves except AZIC,

CAXR, CAYR, CORC, DIPC, TAZI, TDEP and TFDR.


The LSS software system supports all Long Compensated Sonic curves except DT1A,

DT2A, DT3A, DT1B, DT2B, DT3B, DTC1, DTC2 and DTC3.

The NC1 software system supports all Compensated Density Sonde curves except

CACN, DPRD, DPRL, DRRS, HDEN and TNCS. It also supports all Compensated

Neutron Sonde curves except BHT, BHTD, BHTF, NRPD, NPRL, NPRS, TNCS and

XPOR.
