L Donald Maus, Torney M Van Acker, Mark E Ehrhardt: Method and apparatus for controlling pressure and detecting well control problems during drilling of an offshore well using a gas-lifted riser. ExxonMobil Upstream Research Company, Keith A Bell, Nelson V Jaramillo, Gary P Katz, December 30, 2003: US06668943 (77 worldwide citation)

A method and apparatus for controlling the riser base pressure and detecting well control problems, such as kicks or lost circulation, during drilling of an offshore well using a gas-lifted riser. The pressure control apparatus preferably includes two separate control elements, one to adjust the pre ...

Charles R Dawson, Mark W Biegler: Method for installation of evacuated tubular conduits. ExxonMobil Upstream Research Company, Denise Y Wolfs, Gary P Katz, October 21, 2003: US06634430 (56 worldwide citation)

A method of installing tubular conduits (e.g. casing, liners, sand screens) into a highly deviated borehole. A lower plug is attached at one end of a portion of a tubular conduit. This end is inserted into a borehole. After insertion of the length of conduit intended to be buoyancy-aided into the bo ...

Roland P Léauté, Kathy E Corry, B Karl Pustanyk: Liquid addition to steam for enhancing recovery of cyclic steam stimulation or LASER-CSS. ExxonMobil Upstream Research Company, Gary P Katz, March 23, 2004: US06708759 (46 worldwide citation)

LASER-CSS provides a method to improve cyclic steam-based thermal recovery methods for heavy oils and bitumen. A key improvement over prior art consists of mixing liquid hydrocarbons into the injected steam instead of injecting such hydrocarbon as a separate slug in front of a steam stimulation cycl ...

Dale E Nierode: Completion method for one perforated interval per fracture stage during multi-stage fracturing. ExxonMobil Upstream Research Company, Linda A Kubena, Gary P Katz, February 13, 2001: US06186230 (34 worldwide citation)

This invention provides a method for designing a multiple-stage ball sealer-diverted fracture treatment so that only one set of perforations is fractured by each stage of fluid pumped. It further provides a method for predicting the sequencing in which perforated intervals will fracture during treat ...
