High Speed Processing of Financial Information Using FPGA Devices

An under-balanced drilling fluid additive is disclosed which reduces reactive shale and/or clay swelling during under-balanced drilling operations, where the additive includes an effective amount of a choline salt. A method for under-balanced drilling is also disclosed including the step of circulating a drilling fluid including an effective amount of a choline salt to reduce reactive shale and/or clay swelling during under-balanced drilling operations.

A well treatment fluid composition comprises a solvent (such as water), a polymer soluble or hydratable in the solvent, a crosslinking agent, an inorganic breaking agent, and an ester compound. Preferably, the hydratable polymer is a polysaccharide, such as galactomannan, cellulose, or derivatives thereof. The crosslinking agent is preferably a borate, titanate, or zirconium-containing compound. The inorganic breaking agent is preferably a metal-based oxidizing agent, such as an alkaline earth metal or transition metal-based oxidizing agent. The ester compound is preferably an ester of polycarboxylic acid, such as an ester of oxalate, citrate, or ethylenediamine tetraacetate. One example of a suitable ester compound is acetyl triethyl citrate.

Well treatment fluid compositions and methods for their use

A corrosion control system is disclosed including an anionic oxygen inhibitor, a cationic acid inhibitor or dispersant, and a noxious species inhibitor or scavenger for use in a fluid in contact with a metallic surface at low temperature, moderate temperature and especially at high temperature. A drilling fluid, a completion fluid, a production fluid and a geothermal fluid including an effective amount of the corrosion control system is also disclosed as well as methods for making and using same.

Corrosion inhibitor systems for low, moderate and high temperature fluids and methods for making and using same

A method of servicing a wellbore comprising inserting a first tubing member having a flowbore into the wellbore, wherein a manipulatable fracturing tool, or a component thereof, is coupled to the first tubing member and wherein the manipulatable fracturing tool comprises one or more ports configured to alter a flow of fluid through the manipulatable fracturing tool, positioning the manipulatable fracturing tool proximate to a formation zone to be fractured, manipulating the manipulatable fracturing tool to establish fluid communication between the flowbore of the first tubing member and the wellbore, introducing a first component of a composite fluid into the wellbore via the flowbore of the first tubing member, introducing a second component of the composite fluid into the wellbore via an annular space formed by the first tubing member and the wellbore, mixing the first component of the composite fluid with the second component of the composite fluid within the wellbore, and causing a fracture to form or be extended within the formation zone.

High rate stimulation method for deep, large bore completions

A subsurface formation having original in-situ stresses that favor the propagation of a horizontal fracture is penetrated by a borehole. A first fracturing fluid containing a propping material is pumped through the borehole and into the formation at a first depth to propagate a horizontal fracture which alters the in-situ stress field. The pumping of the first fracturing fluid is stopped and a second fracturing fluid is pumped through the borehole and into the formation at a second depth to form a vertical fracture within the field of altered in-situ stress.
