A densitometer assembly comprises a pipe fabricated from a high-yield steel, a radioactive source, and a detector. The radioactive source is mounted on an exterior wall of the pipe and is adapted to emit gamma radiation in a defined beam. The detector is mounted on an opposing, facing exterior wall of the pipe in alignment with the gamma radiation beam and is adapted to detect gamma radiation.

Densitometer assembly for high-pressure flow lines

Methods for reducing settling rates of proppants in fracturing fluids include injecting sufficient gas into the fluid to form bubbles that reduce proppant settling rates. Compositions including proppants made buoyant with gas bubbles.

Methods using low concentrations of gas bubbles to hinder proppant settling

Apparatus and compositions for reducing the viscosity of a gelled fluid is provided. In one embodiment, a viscosity reducing microbe is disposed in a capsule and added to the gelled fluid. The gelled fluid may include a thickening agent adapted to increase its viscosity. Upon release from the capsule, the microbe begins to digest the thickening agent in the gelled fluid and/or releases enzymes that that breakdown the thickening agent.

Apparatus, compositions, and methods of breaking fracturing fluids

A system and method for cavitating a producible formation is disclosed to improve hydrocarbon production and to increase a production rate without an concurrent co-production of formation particulate. The method and system include conglomerating the producible formation using a conglomerating composition. Once the producible formation is conglomerated, the conglomerated, producible formation is produced above its critical draw down pressure to form a cavity surrounding the wellborn in the conglomerated, producible formation and placing the cavitated, conglomerated, producible formation on production below a higher maximum sand free rate (MSFR).

Process and system for creating enhanced cavitation

Apparatus and methods of reducing the viscosity of a gelled fluid is provided. In one embodiment, a viscosity reducing microbe is disposed in a capsule and added to the gelled fluid. The gelled fluid may include a thickening agent adapted to increase its viscosity. Upon release from the capsule, the microbe begins to digest the thickening agent in the gelled fluid and/or releases enzymes that that breakdown the thickening agent.

The present invention provides methods of cementing subterranean zones using cement compositions comprising calcium aluminate, fly ash, sodium polyphosphate and water.

Light weight high temperature well cement compositions and methods

The present invention provides light weight high temperature well cement compositions and methods. The compositions are basically comprised of calcium aluminate, ASTM class F fly ash and water.

Cement compositions and methods for high temperature wells containing carbon dioxide

This invention relates to a method of repairing a hole in and thereby terminating the undesirable flow of fluid through a hole in a casing disposed in a wellbore penetrating a subterranean earth formation which method involves the same use of a hydraulic cement consisting of discrete particles having a particle size not greater than about 30 microns. The cement, which is utilized in a water slurry, has a low density, good thixotropic properties and, in one embodiment, expansive characteristics.
