Kenneth G Nolte: Fracturing fluid breaker system which is activated by fracture closure. The Standard Oil Company, Scott H Brown, Fred E Hook, March 26, 1985: US04506734 (192 worldwide citation)

Disclosed are compositions and related methods of use for reducing the viscosity of a fluid introduced into a subterranean formation. The compositions are introduced into the subterranean formation and are non-reactive to the fluid until activated by the closing of any fractures in the subterranean ...

Kenneth G Nolte: Determination of fracturing fluid loss rate from pressure decline curve. Standard Oil Company, Scott H Brown, Fred E Hook, August 16, 1983: US04398416 (25 worldwide citation)

The fluid loss during the extension of a fracture into a subterranean formation is determined from pressure decline measurements of a calibration fracture extending from a wellbore into subterranean formation. During the decline of the calibration fracturing treatment pressure, the period of time wh ...

Michael B Smith, Kenneth G Nolte: Method for determination of fracture closure pressure. Standard Oil Company, Scott H Brown, Fred E Hook, February 8, 1983: US04372380 (23 worldwide citation)

A method of determining the minimum in-situ stress of an underground formation penetrated by a well. The method includes injecting a fluid at a certain rate into the formation to produce fractures in the formation, backflowing the injected fluid from the well at a rate less than the injection rate, ...

Kenneth G Nolte, Michael B Smith: Determination of maximum fracture pressure. Standard Oil Company, Scott H Brown, Fred E Hook, July 19, 1983: US04393933 (21 worldwide citation)

During injection of fracture fluid into a subterranean formation, the bottomhole treating pressure at which the change in pressure is essentially zero is determined. This pressure is the maximum which should be attained for that formation during fracture and is useful for designing subsequent fractu ...

Kenneth G Nolte, Michael B Smith: Height control technique in hydraulic fracturing treatments. The Standard Oil Company, Scott H Brown, Fred E Hook, October 23, 1984: US04478282 (12 worldwide citation)

To control adverse vertical height growth of the fracture created during hydraulic fracturing treatments of subterranean formations, a nonproppant fluid stage is injected during the treatment. The nonproppant stage comprises a transport fluid and a flow block material. The flow block material can be ...

Gordon F N Cox, Kenneth G Nolte: Ice island construction. Standard Oil Company, John D Gassett, February 21, 1984: US04432669 (8 worldwide citation)

An ice island is constructed in a marine area having a sheet of natural ice whereby, in a basic embodiment, a lower layer of fresh water ice is made by continually adding fresh water to the ice sheet and letting it freeze until the sheet is on bottom. An impervious insulating layer is put on top of ...
