Logging/Downhole measurements strategy

Formation temperature measurements

We plan on using the advanced piston corer temperature tool (APCT-3) to measure formation temperature in the first hole of each site. The APCT-3 can only be used with the APC system.

Core orientation

We plan to orient all APC cores with the FlexIT orientation tool and will make use of nonmagnetic coring hardware to the maximum extent possible.

Downhole wireline logging

Downhole wireline logging using the triple combo and the FMS-sonic tool strings is planned at Sites AA-4B, BB-5, and N90E-2C. The logging tools will be run in the final hole at each site. However, coring is the top priority at each site, and the scheduled logging program may be modified if the coring objectives are not met in the allotted time.
