摘要： Fluid producing wells may be treated with a water-in-oil emulsion for the removal or inhibition of unwanted solid particulates, including pipe dope, asphaltenes and paraffins. Such emulsions are of particular applicability in the displacement of oil base drilling muds and/or residues from such muds from producing wells. The water-in-oil emulsions may optionally contain a dispersing agent as well as a surfactant.

摘要： A low residue well treatment fluid comprises: an aqueous solvent; a gelling agent comprising one or modified polysaccharides, the modified polysaccharides having hydrophilic groups; and a crosslinking composition. The fluid may optionally further comprise a gel breaker, a buffer and/or a proppant. The fluids generate no or minimal residue upon being broken, and are particularly useful in well fracturing operations.

摘要： A hydraulic fracturing composition includes: a superabsorbent polymer in an expanded state and configured to break in response to a breaking condition; a plurality of proppant particles disposed in the superabsorbent polymer prior to release of the plurality of proppant particles from the superabsorbent polymer in response to breaking the superabsorbent polymer; and a fluid to expand the superabsorbent polymer into the expanded state. The hydraulic fracturing composition can be made by contacting a superabsorbent polymer with a fluid to expand the superabsorbent polymer into an expanded state; and disposing a plurality of proppant particles in the superabsorbent polymer to make the hydraulic fracturing composition.

摘要： The allosteric effectors, sulfate and phosphate, can be used with mannanohydrolase enzymes to better control the break of gelled fracturing fluids in wellbore operations. The fracturing fluid contains a hydratable polymer of guar, a guar derivative, a cellulose derivative, a water soluble biopolymer or a combination thereof and a crosslinking agent. The mannanohydrolase enzyme catalyzes the hydrolysis of β-(1,4) mannosidic linkages to break the polymeric backbone.

摘要： A method of approximating or determining at least one dimension or other characteristic of at least one underground geological feature in a zone of interest proximate to a well bore includes generating an electric field in the zone of interest. At least two sensing electrodes are provided in the well bore and configured to detect differences therebetween in electric potential caused by at least one target object in the zone of interest. Proppant containing signal generating devices (SGD) is delivered into the geological feature(s). The SGD generate a detectable signal in response to at least one downhole condition or property. At least one receiver receives the detectable signals and provides data relating thereto. At least one dimension or other characteristic of the geological feature is approximated or determined based at least partially upon data provided by the sensing electrodes and receiver(s).

摘要： Fracturing fluid compositions and methods of fracturing subterranean formations using polyboronic compounds as crosslinking agents are provided. The compositions and methods of the present invention allow for lower polymer loadings because achieving higher fracturing fluid viscosities can be achieved using less polymer than in traditional crosslinked systems.
