20090256575 | ELECTROLOCATION APPARATUS AND METHODS FOR MAPPING FROM A SUBTERRANEAN WELL - In some embodiments, apparatus useful for determining at least one dimension of at least one geological feature of an earthen formation from a subterranean well bore includes at least two emitting electrodes and at least one sensing electrode disposed in the well bore. The emitting electrodes are configured to create an electric field and the at least one sensing electrode is configured to detect perturbations in the electric field created by at least one target object. | 10-15-2009 |
20100301128 | FRAGRANCE DISPENSING WICK AND METHOD - 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. | 12-02-2010 |
20110118155 | LIGHT-WEIGHT PROPPANT FROM HEAT-TREATED PUMICE - 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. | 05-19-2011 |
20130043873 | APPARATUS AND METHODS FOR PROVIDING INFORMATION ABOUT ONE OR MORE SUBTERRANEAN FEATURE - 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). | 02-21-2013 |
20130153222 | LIGHTWEIGHT HOLLOW PARTICLES FOR USE IN CEMENTING - A lightweight composite having an activated surface contains a lightweight hollow core particle having cement grains which may be adhered to the hollow core or embedded in the surface of the hollow core. The hollow core particle may be prepared from calcium carbonate and a mixture of clay, such as bentonite, and a glassy inorganic material, such as glass spheres, glass beads, glass bubbles, borosilicate glass and fiberglass. | 06-20-2013 |
