Take away the wireline and add a more versatile conveyance system - the Reeves Well Shuttle - and the case is no longer so clear-cut. LWD has displaced wireline as the primary source of basic formation evaluation FE data in most offshore directional wells. The market for LWD porosity, resistivity...
This paper focuses on the Casing Drilling Technology used in drilling wells. The performance of Casing Drilling technology in simple wells is proving suitable for more challenging applications. This technology was recently used to successfully drill the surface hole sections of two offshore wells that required directional control, six onshore...
Offshore in the Gulf of Mexico a well was completed at a well depth of 12,200 ft in a sandstone formation. Initial production was recorded at 950 BOPD, 50 BWPD, and 3.5 MMCF of gas. During the next year the production declined to 130 BOPD, 250 BWPD, AND 50 MCF...
