Offshore Magazine's 2002 MWD/LWD Services Directory, which appears ann-ually, includes companies providing servi-ces in the global measurement-while-drilling and logging-while-drilling markets.

For quick and easy reference, the directory is divided into measurement groups, then sub-divided further by company and service line. In any reference guide, there are exceptions to a "rule." To limit the number of exceptions, the following guidelines for this year's directory apply:

•Independent measurement subs are listed as a single entry within their respective measurement categories. If the sub can be used with an associated telemetry or other tools, it is listed again in the respective measurement group.

•Tools with multiple measurement capability are listed in each applicable measurement group.

•Independent measurement sub lengths are listed so the reader can combine desired components as needed.

•Only directional tools capable of greater than one-axis surveys were considered for the directory

•Tool manufacturers are not included in this year's directory. Only companies pro-viding services in the measurement-while-drilling and/or logging-while-drilling market are listed.

The following abbreviations are used in the directory:

TF - Tool face
Azi. - Azimuth
Incl. - Inclination
Accel. - Accelerometer
Mag. - Magnetometer
Op. Sel. - Operator selectable
Opt. - Optional
AAPI - Apparent API
API - American Petroleum Institute
