METHOD OF PROCESSING DATA FROM A DUAL DETECTOR LWD DENSITY LOGGING INSTRUMENT COUPLED WITH AN ACOUSTIC STANDOFF MEASUREMENT

METHOD OF PROCESSING DATA FROM A DUAL DETECTOR LWD DENSITY LOGGING INSTRUMENT COUPLED WITH AN ACOUSTIC STANDOFF MEASUREMENT

A logging-while-drilling density sensor includes a gamma ray source and at least two NaI detectors spaced apart from the source for determining measurements indicative of the formation density. An acoustic caliper is used for making standoff measurements of the NaI detectors. Measurements made by th...

description A logging-while-drilling density sensor includes a gamma ray source and at least two NaI detectors spaced apart from the source for determining measurements indicative of the formation density. An acoustic caliper is used for making standoff measurements of the NaI detectors. Measurements made by the detectors are partitioned into standoff bins. An adaptive spine and rib method uses the standoff measurements to obtain density estimates. The method of the invention may also be used with neutron porosity logging devices.
