摘要:
An embodiment of a method of evaluating fluid trapping in an earth formation includes injecting a water-based fluid into at least one fluid channel fabricated on a substrate, the at least one fluid channel having a pore structure configured to represent a condition of an earth formation. The method also includes injecting oil into an inlet of the at least one fluid channel until at least a selected amount of the injected oil exits the channel, imaging the fluid channel and determining an amount of remaining fluid in the fluid channel after injection of the oil, the remaining fluid being an amount of the oil and/or an amount of the water-based fluid, and estimating a proportion of the total volume of the fluid channel occupied by the remaining fluid to determine an amount of fluid trapping in the pore structure. The method further includes analyzing the amount of fluid trapping.

A diverter fluid includes an aqueous carrier fluid, and a plurality of water-swellable polymer particles having a size of 0.01 to 100,000 micrometers. A method of hydraulically fracturing a subterranean formation penetrated by a reservoir includes injecting a fracturing fluid into the formation at a pressure sufficient to create or enlarge a fracture, injecting a diverter fluid into the formation, and injecting a fracturing fluid into the formation, wherein the flow of the fracturing fluid is impeded by the diverting agent and a surface fracture area of the fracture is increased. A method of controlling the downhole placement of a diverting agent is also disclosed, including injecting a diverter fluid including the diverting agent and an aqueous carrier fluid selected so that the polymer particles are fully swelled after contacting the aqueous carrier fluid for an amount of time sufficient to achieve a desired downhole placement.

There is disclosed a method and system for use in evaluating a system event. A current storage configuration is captured in connection with a data storage system. A system failure event relating to the data storage system is simulated without impacting the data storage system. The system failure event is simulated using the current storage configuration in connection with the data storage system. A system failure event output is provided for enabling evaluation of the potential impact of the system failure event in the data storage system in response to simulating the system failure event.

Described are techniques for searching. Search criteria including parameters is received. It is determined whether to perform searching based on storage provisioned for one or more selected applications identified in the search criteria. If it is determined to perform searching based on storage provisioned for one or more selected applications, first processing is performed in accordance with the search criteria, and otherwise second processing is performed in accordance with the search criteria. Search results produced as a result of one of the first processing and the second processing are received.

摘要:
In some embodiments, a method of approximating or determining at least one dimension 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 while the well bore and geological feature at least partially contain conductive fluid. 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 and provide data relating thereto to at least one data processing system. The data processing system(s) approximates or determines the dimension(s) of the geological feature(s) based at least partially upon data provided by the sensing electrodes.

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).

Methods and compositions useful in inhibiting the formation, growth, and/or maintenance of gas hydrates in a fluid mixture. The gas hydrate inhibitors comprise polyetheramines and acids that are exothermically reacted in situ to produce polyetherammonium compounds.
摘要:
A method of enhancing the productivity of a subterranean formation penetrated by a gas, oil or geothermal well consists of introducing into the formation and/or well a pumpable polymerizable fluid comprising a crosslinkable, monofunctional alkene, multi-functional alkene (such as a difunctional alkene), a heat inducible free radical initiator and brine. The fluid may be used in the thermal insulation of production tubing or transfer pipes and hydraulic fracturing.
