Both wells had substantial uncertainties in the petrophysical assessments of the inflow performance of layers in the reservoir. The results from the chemical tracer technique provided insight...

..., the risk of losses during cement placement has led to inconsistent zonal isolation. A revised strategy for the cementing fluids used during primary cementing based upon these same risks will demonstrate the improved zonal isolation success. The manuscript details the methods, strategies, and case histories...

... Abstract A Gulf of Mexico case history is presented that describes the successful delivery of two (2) deep (27,000-ft) high pressure (>17,500-psi) high rate design (25,000 BOPD) oil wells in an ultra-deep water (+6000-ft) environment. Well conditions, coupled with challenging production...
