A method of treating a subterranean formation may include preparing a mortar slurry, injecting the mortar slurry into the subterranean formation at a pressure sufficient to create a fracture in the subterranean formation, and allowing the mortar slurry to set, forming a mortar in the fracture. The mortar slurry may be designed to form a pervious mortar, to crack under fracture closure pressure, or both.

Method of treating a subterranean formation with a mortar slurry designed to form a permearle mortar

A method of increasing near-wellbore rock strength so as to mitigate or remediate lost circulation events through increased hoop stress in the near-wellbore in a subsurface formation comprises a) cooling a near-wellbore region of the formation, b) allowing a lost circulation material to enter the cooled near-wellbore region; and c) heating the near-wellbore region.

Increasing formation strength through the use of temperature and temperature coupled particulate to increase near borehole hoop stress and fracture gradients

A system and method for producing bitumen or heavy oil from a clastic or carbonate reservoir. The mobility of the bitumen or heavy oil is increased by conductive heating to reduce the viscosity. The bitumen or heavy oil is heated to temperatures below the thermal cracking temperature of the bitumen or heavy oil. As the bitumen or heavy oil is produced, evolved gases or evaporated connate water or both form a gas chamber which acts to replace the volume of the produced fluid required for the gravity drainage process.

Thermally assisted gravity drainage (TAGD)

A method for treating a hydrocarbon containing formation may include providing heat to a first hydrocarbon layer in the formation from a first heater located in an opening in the formation. The opening and the first heater may have a horizontal or inclined portion located in the first hydrocarbon layer and at least one connecting portion extending between the horizontal or inclined portion and the surface. Isolation material is placed in the opening such that the isolation material partially isolates the layer in which the horizontal or inclined portion of the first heater is located. An additional horizontal or inclined opening portion that extends from at least one of the connecting portions of the opening is formed in a second hydrocarbon layer. A second heater to provide heat the second hydrocarbon formation is placed in the additional substantially horizontal opening portion.

Time sequenced heating of multiple layers in a hydrocarbon containing formation

Disclosed is an auxiliary method for freeing a drill pipe stuck due to build up of filter cake, which provides a reduction in the amount of force required to free said pipe which comprises:

Method of freeing stuck drill pipe

A method for producing an epoxy polyetherpolyol having 15 to 75 wt. % epoxy comprising heating a polyol and catalyst to initiate condensation, removing water, introducing sufficient epoxy into the reaction mixture to give 15 to 75 wt. % epoxy in the product. Generally, between 0.5 and 1.19 moles of water per mole of polyol are removed. In one embodiment at least 95 wt. % of all of the polyol is introduced initially into the reaction zone. In another embodiment the condensation is terminated prior to 93 percent completion. Also provided are novel compositions suitable for drilling fluids, adhesives and coatings.

Copolymerization of polyetherpolyols with epoxy resins

Reduction of the adhesion of polyethercyclicpolyol (PECP) to metals by preparing the PECP by condensing polyol molecules by reactive distillation and replacing part of the polyol with an alcohol of lower hydroxyl content than the polyol.

A novel process and apparatus have been contrived for the study of the bit/stabilizer balling phenomenon in the laboratory. The device permits a standard testing procedure using a specially designed bob simulating the drill bit for comparing degrees of balling for different rock formations under different drilling conditions involving variable and controlled parameters like weight-on-bit, revolutions-per-minute (rpm), drilling fluids, etc.
