In a method of gravel packing a wellbore in a subterranean formation, the wellbore comprising a cased section and an uncased section, the method may include pumping into the wellbore a gravel pack composition comprising gravel and a carrier fluid comprising an invert emulsion fluid, where the invert emulsion fluid may comprise: an oleaginous external phase; a non-oleaginous internal phase, wherein a ratio of the oleaginous external phase and non-oleaginous internal phase is less than 50:50 and an emulsifier stabilizing the oleaginous external phase and the non-oleaginous internal phase.

Methods of using invert emulsion fluids with high internal phase concentration

A wellbore fluid may include an oleaginous continuous phase, one or more magnetic carbon nanoribbons, and at least one weighting agent. A method of performing wellbore operations may include circulating a wellbore fluid comprising a magnetic carbon nanoribbon composition and a base fluid through a wellbore. A method for electrical logging of a subterranean well may include placing into the subterranean well a logging medium, wherein the logging medium comprises a non-aqueous fluid and one or more magnetic carbon nanoribbons, wherein the one or more magnetic carbon nanoribbons are present in a concentration so as to permit the electrical logging of the subterranean well; and acquiring an electrical log of the subterranean well.

Wellbore fluids incorporating magnetic carbon nanoribbons and magnetic functionalized carbon nanoribbons and methods of using the same

A method of treating a formation that includes injecting gelling components curable by a moisture cure into a selected region of the formation; and controlling the onset of curing of the gelling components by contacting the gelling components with a drying agent is disclosed.

Methods of delaying the curing of moisture sensitive curable elastomers

A method of treating a formation that includes exposing a region of the formation occupied by a hydrolysable gel to a hydrolyzing agent; and allowing sufficient time for the hydrolyzing agent to hydrolyze the gel. Various methods may also include the use of a swelling agent to allow for expansion of the gel.

Degradable non-aqueous gel systems

A composition that includes a product resulting from a condensation reaction of quebracho with at least one organophilic species that includes a reactive amine is disclosed.

Fluid loss additive for oil-based muds

A low electrical conductivity water-based wellbore fluid for use in drilling wells through a formation containing a clay which swells in the presence of water, said wellbore fluid that includes an aqueous base fluid; and a polymeric non-ionic tertiary amine is disclosed. Methods of using such fluids are also disclosed.

Low conductivity water based wellbore fluid

A low toxicity composition and method of reducing the swelling of clay in well comprising circulating in the well a water-based fluid comprising a functionally effective concentration of the additive formed from the following reaction of a tertiary amine of the following general formula: wherein Rand Rare alkyl or hydroxyalkyl groups with one to three carbon atoms or combinations thereof, and Ris a hydroxyalkyl group with one to three carbon atoms, with an alkylating agent of the following general formula:R-Awherein R is an alkyl radical with one to three carbon atoms, and A is an organic or inorganic anion selected from the group consisting of sulfate, phosphate, carbonate, and combinations thereof.

Low toxicity shale hydration inhibition agent and method of use

A drilling fluid having an oleaginous fluid that forms the continuous phase; a non-oleaginous fluid, which is the discontinuous phase; a primary emulsifier in sufficient concentration to stabilize the invert emulsion; and a rheology modifier, which serves to moderate the rheology change across a temperature range of 40 to 150&#xb0; C. The rheology modifier may be a dimer poly-carboxylic Cto Cfatty acid, trimer poly-carboxylic Cto Cfatty acid, tetramer poly-carboxylic Cto Cfatty acid, mixtures of these acids, or a polyamide wherein the polyamide is the condensation reaction product of a C-Cfatty acid and a polyamine selected from the group consisting of diethylenetriamine, triethylenetetramine; and pentaethylenetetramine. The drilling fluid preferably includes a weighting agent or bridging agent which may be selected from galena, hematite, magnetite, iron oxides, illmenite, barite, siderite, celestite, dolomite, calcite as well as combinations and mixtures of these and similar compounds. Optionally organophillic clay, fluid loss agents, alkali reserve materials, and other conventional invert emulsion drilling fluid components may be added to the drilling fluid.

Flat rheology drilling fluid

A method of using a water-base wellbore fluid in subterranean wells that penetrate through a subterranean formation containing a shale which swells in the presence of water. The well bore fluid includes, an aqueous based continuous phase, and a shale hydration inhibition agent. One illustrative shale hydration inhibition agent is preferably the reaction product of a hydrogenation reaction of the product of the reaction of an aromatic amine with an aldehyde, preferably formaldehyde.

The shale hydration inhibition agent is present in sufficient concentration to substantially reduce the swelling of shale drilling cuttings upon contact with the fluid.

Shale hydration inhibition agent and method of use

A water-base fluid for use in drilling, cementing, workover, fracturing and abandonment of subterranean wells through a formation containing shale which swells in the presence of water. In one illustrative embodiment, the drilling fluid is composed of an aqueous based continuous phase, a weighting agent, and a shale hydration inhibition agent. The shale hydration inhibition agent should have the general formula: in which R and R' independently selected from hydrogen, methyl, ethyl or propyl, and X has a value from 1 to 6. The shale hydration inhibition agent is present in sufficient concentration to substantially reduce the swelling of shale drilling cuttings upon contact with the drilling fluid. The drilling fluid may be formulated to include a wide variety of components of aqueous based drilling fluids, such as weighting agents, fluid loss control agents, suspending agents, viscosifying agents, rheology control agents, as well as other compounds and materials known to one of skill in the art. The fluids may also be used in fracturing and the disposal by reinjection of drilling cutting into a selected subterranean disposal formation.

A method of fracturing a subterranean formation, the method including injecting a fracturing fluid into the well, wherein said fracturing fluid includes: an oleaginous fluid; and an amine surfactant having the structure wherein R is a C-Caliphatic hydrocarbon; R' is an independently selectable from hydrogen or Cto Calkyl; A is NH or O, and 1&#x2266;x+y&#x2266;3; and oil-wet proppant material.
