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).

A wick which comprises a network matrix ceramic that is contacted either directly or indirectly with a liquid composition such as a fragrance-containing composition. The wick absorbs and transports the liquid composition through capillary action, and the composition is subsequently diffused into the surrounding ambient atmosphere.

Low vapor pressure compound-based fuels are provided. These fuels are useful in catalytic burner systems that can be used to disperse fragrances, insecticides, insect repellants (e.g., citronella), aromatherapy compounds, medicinal compounds, deodorizing compounds, disinfectant compositions, fungicides and herbicides.
摘要:
A catalytic burner is provided. The method of using the catalytic burner utilizes flameless combustion. The absence of a flame results in a more even temperature distribution throughout the length of the burner. The invention lowers the autoignition temperature by placing a catalytic surface within the burner and offers relatively even distribution of heat from the burner. Thus, the amount and location of the combustion reaction can be controlled by varying the amount and distribution of catalyst within the burner.

A variety of methods and compositions are disclosed, including, in one embodiment, a method of cementing in a subterranean formation, comprising: providing a set-delayed cement composition comprising water, pumice, hydrated lime, and a set retarder; activating the set-delayed cement composition; introducing the set-delayed cement composition into a subterranean formation; and allowing the set-delayed cement composition to set in the subterranean formation.

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.

摘要:
A process for forming a strong, low-density proppant, which process includes heating pumice particulates, or shaped agglomerates thereof, so as to form heat-treated pumice particulates, or heat-treated, shaped pumice agglomerates, having an apparent density of 2.4 or less and a crush resistance of no more than 10% fines at 4000 psi. Proppants, and well treatment fluids comprising proppants, meeting these characteristics and processes for treating subterranean formations using fluids which include such proppants are also described.
