Methods of making particulates for use in a subterranean application comprising: providing particulates of a settable composition comprising a cementitious material, a filler material, and an activator of the cementitious material; and pre-curing the particulates until the particulates reach a crush strength of about 50 psi or greater; and curing the pre-cured particulates at a temperature in the range of about 230&#xb0; F. to about 600&#xb0; F., so that at least a portion of the particulates comprise a newly formed crystalline phase.

Cement-based particulates and methods of use

A method of making a proppant is provided, wherein the method includes the steps of: (a) forming a particulate comprising: (i) a binder; and (ii) a filler; and (b) sintering the particulate to form a sintered proppant, wherein the sintered proppant comprises: (i) at least 20 wt % of alkaline earth oxide equivalent; and (ii) at least 20 wt % of silicon dioxide equivalent. A method of treating (e.g., fracturing) a subterranean formation is provided, the method including the steps of: (a) suspending the sintered proppant in a treatment fluid; and (b) introducing the sintered proppant into the subterranean formation. The sintered proppant is made with a raw material selected from the group consisting of: unhydrated cement, hydrated cement (e.g., construction cement or concrete waste), kiln dust, fly ash, limestone, lime, talc, olivine, dolomite, clay that contains a substantial concentration of alkaline earth oxide equivalent, and any combination thereof in any proportion.

The present disclosure addressed apparatus and methods for forming an annular isolator in a borehole after installation of production tubing. Annular seal means are carried in or on production tubing as it is run into a borehole. In conjunction with expansion of the tubing, the seal is deployed to form an annular isolator. An inflatable element carried on the tubing may be inflated with a fluid carried in the tubing and forced into the inflatable element during expansion of the tubing. Reactive chemicals may be carried in the tubing and injected into the annulus to react with each other and ambient fluids to increase in volume and harden into an annular seal. An elastomeric sleeve, ring or band carried on the tubing may be expanded into contact with a borehole wall and may have its radial dimension increased in conjunction with tubing expansion to form an annular isolator.

Methods are provided for increasing the temperature of a section of conduit used for the production or transmission of hydrocarbon. According to one aspect, the method includes the steps of: (a) forming a treatment fluid comprising: (i) a carrier fluid; and (ii) a first reactant and a second reactant; and (b) introducing the treatment fluid into a section of conduit used for the production or transmission of hydrocarbon. The first reactant and second reactant are selected for being capable of reacting together in an exothermic chemical reaction; and the first and second reactant are in at least sufficient concentrations in the carrier fluid to generate a theoretical heat of reaction of at least 1,000 kJ/liter of the treatment fluid. At least some of at least one of the first reactant and the second reactant is suspended in the carrier fluid in a solid form that is adapted to help control the release of the reactant into the carrier fluid.

This invention relates to subterranean treatment operations. More particularly, this invention provides methods that may be useful in providing void-free barriers between a subterranean formation and a portion of a well bore. A nonlimiting example of a method is a method of degrading a filter cake in a subterranean formation. Another nonlimiting example of a method is a method of producing hydrocarbons from a subterranean formation.

Methods and compositions are provided for treating a subterranean formation penetrated by a well. The method includes the steps of: (a) forming a treatment fluid, and (b) introducing the treatment fluid into the well and into contact with the formation. The treatment fluid includes: (1) water; (2) a water-soluble polysaccoharide capable of increasing the viscosity of the water or a water-soluble polysaccharide and a crosslinking agent for the water-soluble polysaccharide; (3) a breaker comprising at least one member selected from the group consisting of a source of chlorite ions and a source of hypochlorite ions; and (4) a breaker moderator comprising at least one member selected from the group consisting of a source of magnesium ions and a source of calcium ions.

Improved methods and compositions for degrading filter cake deposited in a subterranean formation are provided. These methods and compositions utilize particulates coated with acid-releasing degradable material wherein the released acid is used to degrade a filter cake.

Compositions and methods for degrading filter cake

Methods are provided for removing filter cake containing a bridging agent soluble in a carboxylic acid salt from a formation fluids producing zone penetrated by a well bore. The methods basically comprise the steps of introducing in an aqueous carrier liquid a carboxylic acid ester and a base for slowly catalyzing the hydrolysis of the ester and forming a carboxylic acid salt therewith into the producing zone, and allowing the base to catalyze the hydrolysis of the carboxylic acid ester to form the carboxylic acid salt so that the carboxylic acid salt dissolves the bridging agent and the filter cake is removed.
