Gordon Technologies’ PWD tool stores memory parameters such as Annular Pressure, Max/Min pressure in the Annulus, Drill Pipe Pressure and Max/Min pressure in the drill pipe. Annular Temperature is also stored in memory every minute. Our pressure logs assist operators in diagnosing bit failures, picking up mud motor stalls, and measuring cuttings effect on mud weight in hole. When coupled with WOB and Torque Measurements (Track 4), adjustments can be made to drill better wells. Equivalent Circulating Density for all pressures are calculated on the surface in real-time providing information about the health of the mud system while drilling.
