An assembly and methods for constructing a MONOWELL include a monodiameter casing disposed in a monodiameter wellbore having diametric efficiency with a monobore production delivery system disposed within the monodiameter casing. An assembly for constructing a monodiameter wellbore includes a bottomhole assembly having a overgauge hole drilling member, a directional steering assembly, a measurement while drilling tool, and a logging while drilling tool; a work string attached to the bottomhole assembly and extending to the surface; drilling fluids flowing through the work string and bottomhole assembly; chemical casing casing the borehole; expandable casing disposed in the wellbore; and a sealing composition disposed between the expandable casing and the wellbore.

A method of fracturing subterranean zones at temperature below about 200&#xb0; F. wherein the fracturing fluid comprises water, a viscosity increasing gelling agent, a particulate proppant material, a delayed viscosity breaker for causing the fracturing fluid to revert to a thin fluid and a breaker activator comprising a mixture selected from the group of a mixture of cobaltous acetate and the sodium salt of ethylenediaminetetraacetic acid and a mixture of thioglycolic acid and sodium molybdate.

Methods of fracturing subterranean zones, fracturing fluids and breaker activators therefor

The present invention provides cement compositions comprising an improved fluid loss control additive, and methods for cementing in a subterranean formation using such cement compositions. The cement compositions comprise a hydraulic cement, water, and a fluid loss control additive comprising at least two polymers connected by a pH-sensitive crosslink. Optionally, other ingredients may be included in the compositions.

Cement compositions with improved fluid loss characteristics and methods of cementing in subterranean formations

A method of treating a subterranean formation comprising contacting the formation with an aqueous composition of desired viscosity. The aqueous composition is prepared by polymerizing water-soluble monomers in an aqueous solvent with a free radical initiator comprising a reduction-oxidation couple between cobaltous amine complex and an alkali metal or ammonium salt of peroxydisulfate.

Method of recovering hydrocarbons from subterranean formations

By this invention there is provided a method for dissolving cobalt (II) and cobalt (III) compounds by contacting said compounds with an aqueous acidic solution comprising a compound containing a radical selected from the group consisting of cyano, cyanato, thiocyanato, ferricyano and mixtures thereof.
