A method of cementing an annular space between a pipe string and a well bore, the method comprising the steps of (a) providing a cement composition including a calcium-deficient calcium silicate; (b) mixing the cement composition with water to form a cement slurry; (c) mixing the cement slurry composition with carbon dioxide form a foamed cement; and (d) placing the foamed cement in the annular space between the pipe string and the wellbore.

Methods involving cements that employ carbon dioxide as a reactant

A system for cementing a wellbore penetrating an earth formation into which a pipe extends. A cement material is positioned in the space between the wellbore and the pipe by circulated capsules containing the cement material through the pipe into the space between the wellbore and the pipe. The capsules contain the cementing material encapsulated in a shell. The capsules are added to a fluid and the fluid with capsules is circulated through the pipe into the space between the wellbore and the pipe. The shell is breached once the capsules contain the cementing material are in position in the space between the wellbore and the pipe.

Disclosed is a composition comprising a chemical formulation useful for creating geosynthetic composites in-situ that includes a melamine-formaldehyde resin in a non-aqueous drilling fluid.

Geosynthetic composite for borehole strengthening

A method for improving bonding and sealing in a well, comprising providing a wellbore, providing a pipe, coating an outside surface of the pipe with an adhesive thermoplastic resin, running the coated pipe into the wellbore, and causing the temperature of said wellbore to increase to a temperature greater than a melting temperature of said adhesive thermoplastic resin.

Method for sealing pipe in a well

Disclosed is a composition comprising a chemical formulation useful for creating geosynthetic composites in-situ, which includes a reactive ester having at least one carbon-carbon double bond, preferably a vinyl ester of a Cto Cversatic acid or vinyl ester of a long chain fatty acid, or a combination thereof, at least one unsaturated thermoplastic elastomer soluble in the reactive ester; at least one di- or tri-functional acrylate or methacrylate monomer. The formulation may further include a non-aqueous drilling fluid.

A barrier system for a subsurface treatment area is described. The barrier system includes a first barrier formed around at least a portion of the subsurface treatment area. The first barrier is configured to inhibit fluid from exiting or entering the subsurface treatment area. A second barrier is formed around at least a portion of the first barrier. A separation space exists between the first barrier and the second barrier.

Double barrier system for an in situ conversion process

A method for strengthening a wellbore with an exposed geological formation, the method including: determining or estimating material properties of the exposed geological formation; determining changes necessary in material properties of the exposed geologic formation to achieve desired improvements in property of the exposed geologic formation; and treating the geological formation to improve material property values by injecting a formulation that hardens in-situ to form a geosynthetic composite. In another aspect, an apparatus for utilizing the described method with minimal handling of chemicals includes is an automated in-line chemical metering and pumping apparatus that requires no large mixing tank.

Method and apparatus for performing chemical treatments of exposed geological formations

The drilling mud with a lowered coefficient of friction having a silicate-based mud and a lubricant selected from the group consisting of: glycosides, alkylpolyalkoxyalcohols, alcohol ester polymers, amine phosphates, starch and combinations thereof.

Silica-based drilling mud comprising glycoside lubricants with amino-linked alkyl chains

An apparatus and method for repairing a wellbore casing (). An opening () in a wellbore casing () is located using a logging tool (). An expandable tubular member () is then positioned in opposition to the opening () in the wellbore casing (). The expandable tubular member () is then radially expanded into intimate contact with the wellbore casing ().

Wellbore casing repair

A drilling mud is converted in-situ to a cement by addition of blast furnace slag.

Solidification of water based muds

A cementitious slurry is prepared from drilling fluid, blast furnace slag and an emulsion comprising an oil external phase and an aqueous internal phase having therein a additive for said cementitious slurry. In a preferred embodiment the additive is an accelerator for the blast furnace slag such as sodium hydroxide. This allows mixing the additive with the drilling fluid and blast furnace slag without immediate contact between the additive and the other ingredients. After the cementitious slurry has been mixed and pumped into position in a wellbore, the emulsion breaks and the additives are released.

Emulsion in blast furnace slag mud solidification

A method and composition for cementing a well by combining water, blast furnace slag and a phosphate ion-containing compound to form a cement slurry, displacing the cement slurry into the well, and allowing the cement slurry to set.

Optimizing blast furnace slag cements

The thermal stability of hardened drilling mud-concrete is improved by incorporating blast furnace slag, microfine slag or fine ground glass into the mud-concrete prior to hardening.
