Lightweight cement blends containing pumice, and their use in cementing oil and gas... Agent: Edward Yoo C/o Bennett Jones

20090099046 - Methods, drilling fluids and drilling fluid additives for limiting tar sand accretion on metal surfaces: Drilling fluids, drilling fluid additives and methods for oil well drilling feature quaternary ammonium salts and act to reduce accretion of bituminous material on metal surfaces of drilling equipment.... Agent: Ade & Company Inc.

20090099047 - Fusing materials for prevention of lost circulation: A method is given for reducing fluid loss in downhole operations such as drilling and completion. A composition containing a fusing solid is injected into the fluid loss flow path; the fusing solid fuses at formation temperature when the injection pressure is released and the formation matrix surfaces forming the... Agent: Schlumberger Technology Corporation David Cate

20090093382 - Methods and compositions for pre-emptively controlling undesirable water production from oil and gas wells`: A method for pre-emptively reducing the production of water in an oil and gas well is provided. In one embodiment, a drill-in fluid having a relative permeability modifier (RPM) capable of impeding the production of water is introduced into the wellbore during drilling operations. In a second embodiment, a completion... Agent: Howrey LLP
