An anchor tool having a housing, a one-way restrictor device in fluid communication with the housing, and a stabilizer affixed to the housing. The one-way restrictor device is configured to allow restricted flow in a first direction, and to allow flow in a second direction.

Process and apparatus to improve reliability of pinpoint stimulation operations

Stimulation operations can be conducted by isolating portions of a subterranean formation adjacent to a highly deviated well bore. The planned settled height of a sand plug in a well bore adjacent a first zone of the subterranean formation is determined. The first zone is then perforated using a hydrajetting tool which is oriented so as to form perforations below the planned settled height of the sand plug.

Method of perforating for effective sand plug placement in horizontal wells

Methods for setting particulate plugs in at least partially horizontal sections of well bores are disclosed. In one embodiment, a method comprises the step of selecting a deposition location for a particulate plug within the at least partially horizontal section of the well bore. The method further comprises the step of providing a pumping conduit capable of delivering slurries to the deposition location. The method further comprises the step of pumping a first slurry through the pumping conduit to the deposition location such that a velocity of the first slurry in the well bore at the deposition location is less than or equal to the critical velocity of the first slurry in the well bore at the deposition location.

Methods of setting particulate plugs in horizontal well bores using low-rate slurries

Methods of isolating portions of a subterranean formation adjacent to a highly deviated well bore having a downstream end and an upstream end and substantially filling a first zone with a sand plug comprising lightweight particulates having a specific gravity of below about 1.25 so as to substantially isolate the first zone from the second zone wherein the first zone is located closer to the downstream end of the wellbore than the second zone.

Sand plugs and placing sand plugs in highly deviated wells

Methods and compositions for wellbore treating fluids, especially cementitious compositions that include interground cement clinker and zeolite, with and without gypsum.

Cementitious compositions containing interground cement clinker and zeolite

Methods for cementing in a subterranean zone, which use a cement composition that includes zeolite, cementitious material, proportioned fluid loss control additives and a mixing fluid. Cement compositions containing proportioned fluid loss control additives, and methods of making cement compositions containing proportioned fluid loss control additives.

Fluid loss additives for cement slurries

Methods and cement compositions are provided for sealing a subterranean zone penetrated by a wellbore, wherein the cement composition comprises zeolite, cementitious material, and a mixing fluid.

Zeolite-containing cement composition

A method and cement composition is provided for sealing a subterranean zone penetrated by a well bore, wherein the cement composition comprises zeolite, cementitious material, and water sufficient to form a slurry.

A method of stimulating a downhole formation according to which a plurality of jet nozzles are located in a spaced relation to the wall of the formation to form an annulus between the nozzles and the formation. An acid-containing, stimulation fluid is pumped at a predetermined pressure through the nozzles, into the annulus and against the wall of the formation. A gas is pumped into the annulus so that the stimulation fluid mixes with the gas to generate foam before the mixture is jetted towards the formation to impact the wall of the formation.

Method for acid stimulating a subterranean well formation for improving hydrocarbon production

A method of fracturing a downhole formation according to which a plurality of jet nozzles are located in a spaced relation to the wall of the formation to form an annulus between the nozzles and the formation. A non-acid containing stimulation fluid is pumped at a predetermined pressure through the nozzles, into the annulus, and against the wall of the formation, and a gas is introduced into the annulus so that the stimulation fluid mixes with the gas to generate foam before the mixture is jetted towards the formation to form fractures in the formation.
