Drilling and Completion Fluids - Gas Hydrate Inhibition (additives)/remediation - Problems associated with connectors and well control Deepwells 25,000in ultra-deep waste Fluid HTHP vs. HT, LT, HP combination of ultra-deep water environment riser effect (radiator) Loss circulation material innovations for severe cases Water base muds with stable rheology, lubricity, high ROP SBM with stable rheology, lubricity, temp and inhibition which will pass minimum toxicity requirements of NPDES . LAO replacement Degradation requirements must be met by new regulations Minimum cuttings retention properties and equipment to recover base at<6-8% Drill in fluids for horizontals wells (drilling/completion) with expectable properties i.e., low solid brines with high density, stable properties (TCP) in DW environment of low temp/high temp/pressure/low temp, environmentally friendly salt saturated Cement technology high angle hole plugs slurries more tolerant of contamination
