Oil-soluble well treatment agents may be slowly released into a well or a subterranean formation by use of an aqueous fluid of (i) an oil-in-water dispersion having the oil-soluble well treatment agent as a dispersed phase and (ii) a second component having an oil-soluble or water-soluble primer coated onto a portion of its surface. The amount of the oil-soluble well treatment agent in the oil-in-water dispersion is from 20 to 50 weight percent and the average particle size of the oil-soluble well treatment agent in the dispersion may be from 0.005 to 2 micrometers. The oil-in-water dispersion may further contain a water-soluble well treatment agent.

Method of introducing oil-soluble well treatment agent into a well or subterranean formation

A fluid for use in hydraulic fracturing contains underivatized guar or a guar gum derivative as viscosifying or gelling polymer, a crosslinking agent, carbon dioxide as foaming agent and urea and, optionally, a bifunctional organic compound containing at least one hydroxyl group and at least one quaternary group and, optionally, a non-gaseous foaming agent. The fluid may be characterized by a low pH such as a pH than or equal to 3.0 and less than or equal to 5.0.

Methods of using energized well treating fluids

The flow of well treatment fluids may be diverted from a high permeability zone to a low permeability zone within a fracture network within a subterranean formation by use of a mixture comprising a dissolvable diverter and a proppant. At least a portion of the high permeability zone is propped open with the proppant of the mixture and at least a portion of the high permeability zone is blocked with the diverter. A fluid is then pumped into the subterranean formation and into a lower permeability zone of the formation farther from the wellbore. The diverter in the high permeability zones may then be dissolved at in-situ reservoir conditions and hydrocarbons produced from the high permeability propped zones of the fracture network. The mixture has particular applicability in the enhancement of production or hydrocarbons from high permeability zones in a fracture network located near the wellbore.

Method of using diverter and proppant mixture

A method of reducing water saturation onto surfaces exposed to hydrocarbons during the production of hydrocarbons from subterranean formations by altering the wettability of the surface of the formation with surface modified nanoparticles.

Methods of altering the wettability of surfaces to enhance hydrocarbon production

A system for slowly releasing an oil-soluble well treatment agent into a well or a subterranean formation includes a composite of the oil-soluble well treatment agent associated with a second component. The amount of the oil-soluble well treatment agent in the composite is from 20 to 35 weight percent and the average particle size of the oil-soluble well treatment agent in the composite is less than or equal to 1 micrometer. The composite may further contain a water-soluble well treatment agent.

Delivery system for oil-soluble well treatment agents and methods of using the same

The strength of a proppant or sand control particulate may be improved by coating the proppant to form a composite. The composite has enhanced compressive strength between about 34 to about 130 MPa and minimizes the spelling of fines at closure stresses in excess of 5,000 psi. Conductivity of fractures is further enhanced by forming a pack of the composites in the fracture.

Use of composites having coating of reaction product of silicates and polyacrylic acid

The complexity of a fracture network may be enhanced during a hydraulic fracturing operation by monitoring operational parameters of the fracturing job and altering stress conditions in the well in response to the monitoring of the operational parameters. The operational parameters monitored may include the injection rate of the pumped fluid, the density of the pumped fluid or the bottomhole pressure of the well after the fluid is pumped. The method provides an increase to the stimulated reservoir volume (SRV).

Methods of improving hydraulic fracture network

Fluids produced from a fractured subterranean formation may be monitored by pumping into the well a fracturing fluid which contains a tracer. The method may be used to monitor produced hydrocarbons as well as produced water. The tracer may also be used in a sand control, frac pack or acid fracturing operation. The tracer is a component of a composite where it may be immobilized within a matrix (such as an emulsion) or porous particulate, onto a support or compressed with a binder into a solid particulate. The tracer may be slowly released from the composite.

Method of using controlled release tracers

A well treatment fluid containing borated galactomannan may be used to isolate a pre-determined productive zone in an oil or gas well. The fluid is pumped into the well in a substantially non-hydrated form and forms a temporary seal. The fluid may be used as a chemical packer in place of a mechanical packer. After the pre-determined productive zone is isolated, a well intervention operation may be performed within the isolated pre-determined zone.

Well intervention method using a chemical barrier

The flow of a fluid may be diverted from a high permeability zone to a low permeability portion of a subterranean formation by use of particulates comprising dicarboxylic acid, ester or an anhydride of the formula:  or an anhydride thereof, wherein Ris &#x2014;COO&#x2014;(RO)y&#x2014;Ror &#x2014;H; Rand Rare selected from the group consisting of &#x2014;H and &#x2014;COO&#x2014;(RO)y&#x2014;R, provided both Rand Rare &#x2014;COO&#x2014;(RO)y&#x2014;Rwhen Ris &#x2014;H and further provided only one of Ror Ris &#x2014;COO&#x2014;(RO)y&#x2014;Rwhen Ris &#x2014;COO&#x2014;(RO)y&#x2014;R, Ris &#x2014;H or a C-Calkyl group, Ris a C-Calkylene group, and each y isto. The dicarboxylic acid, ester or anhydride may further be admixed with an aliphatic polyester having the general formula of repeating units:  where n is an integer betweenandand R is selected from the group consisting of hydrogen, alkyl, aryl, alkylaryl, acetyl, heteroatoms, and mixtures; thereof.

Well treatment operations using diverting system

A fines-fixing agent that has improved compatibility with organic complexed borate fracturing fluids is disclosed. Existing fines fixing agents have a high concentration of unreacted caustic that results in a product pH of approximately 12. This high pH affects the crosslinker and the overall fracturing fluid system stability, promoting precipitation of the organic crosslinker. These effects can be mitigated by neutralizing the fines fixing agents with an acid such as hydrochloric or acetic acid to a pH of 6 or lower.

Fines fixing agent having improved compatibility with organic complexed borate fracturing fluids

A fracturing method wherein a foamed or energized fluid comprising natural gas is introduced into a subterranean formation to enhance or create fractures and to enhance production of hydrocarbons from a reservoir penetrated by a wellbore.

Method of treating a subterranean formation with natural gas

A method of treating a subterranean formation comprises forming a storable aqueous suspension comprising a carrier fluid, a superabsorbent polymer, a proppant the proppant being suspended in the carrier fluid as a substantially perfectly supported particulate; diluting the storable aqueous suspension in-line to a desired concentration; and introducing the diluted storable aqueous suspension into the subterranean formation. A sand control method is also disclosed.

Methods of using superabsorbent polymers for fracturing and sand control applications

Systems and methods for conducting production logging for a wellbore are described which incorporate production logging sensors into a bottom hole assembly which is run in on coiled tubing. The production logging system may include a tool for also conducting a secondary operation, such as milling, fishing, perforation or clean out.

Coiled tubing telemetry system and method for production logging and profiling

Non-spherical particulates are useful in the stimulation of subterranean formations. A proppant pack composed of the non-spherical particulates exhibits greater porosity than a corresponding proppant pack composed of spherical particulates. In addition, the non-spherical particulates exhibit higher conductivity at higher stresses than spherical shaped particulates.
