2009 GOM JIP LWD Program
 

GoM JIP Leg II will feature a state-of-the-art LWD tool combination that will provide unprecedented information on the nature of the sediments and their pore fill constituents. The program will feature full research-level LWD data on formation lithology and porosity, and will include Schlumberger’s MP3 (quadrapole sonic tool) and PeriScope (3-D high-resolution resistivity) tools. These tools will provide full 3-D information on the both acoustic (both compressional and shear wave) and electrical properties of the sediment enabling the improved evaluation of gas hydrate in both pore filling and fracture-filling modes.

This full suite of LWD tools includes the 4.75" MP3 multipole acoustic tool immediately behind the 6.75" bit, followed by an 8.5" reamer which opens up the hole for the 6.75" LWD tools that follow. These include the geoVISION resistivity imaging tool, the EcoScope integrated propagation resistivity, density and neutron tool, the TeleScope MWD tool, the PeriScope directional propagation resistivity tool, and the sonicVISION monopole acoustic tool whose sensors are ~160 ft above the bit.
