Figure F4. Drilling parameters and gamma ray log vs. time for MWD-APWD operations in Hole C0003A. ATMP_MWD = annular temperature from the real-time APWD tool, GR_RAB_RT = gamma ray resistivity-at-the-bit (real time), ECD = equivalent circulating density, APRS = average annular pressure, TRPM = MWD turbine rotation speed, TRPM_RT = TRMP (real time), CRPM = collar rotation, SWOB = surface weight on bit, HKLD = hook load, SPPA = standpipe pressure, ROP = rate of penetration, ROP_5ft = 5 feet averaged ROP, LSF = LWD depth below seafloor, DRF = drillers depth below rig floor.
