||PCT/RU2014/000228||LLC "TOPCON POSITIONING SYSTEMS"||ZABEGAEV, Andrey Nikolaevich|
Disclosed is a method for mapping network identifiers to a set of sensor modules that measure a three-dimensional action vector and that are sensitive to orientation in three-dimensional space. Each sensor module is mounted at a different position on a machine such that the orientation of each sensor module is different. The method includes one or two stages. In the first stage, the machine is placed in a stationary state, and measurements of a static action vector from a sensor module identified by a network identifier are correlated with expected measurements from a sensor module having a corresponding orientation and corresponding position. In the second stage, the machine is placed in a dynamic state, and measurements of a dynamic action vector from a sensor module identified by a network identifier are correlated with expected measurements from a sensor module having a corresponding orientation and corresponding position.
WO/2015/152754 COMPOSITONS AND METHODS FOR CURING LOST CIRCULATION||WO||08.10.2015|
||PCT/RU2014/000232||SCHLUMBERGER CANADA LIMITED||MINIKH, Olga Alexandrovna|
Adding shapeable particles to drilling fluids may be useful for curing lost circulation. When the shapeable particles are pumped downhole through the drillpipe and the drillbit, they may deform when exposed to shear as they pass through the drillbit nozzles. While circulating back toward the surface they may relax at least partially and assume the shape of cracks or voids they encounter along the formation wall, thereby stopping losses.

The present invention can be used in the oil and gas industry and relates to a method for modifying and delivering proppants (propping agents) during well operations, in particular hydraulic fracturing and/or gravel packing. By modifying the surface of a proppant using an emulsified treatment material, the invention makes it possible, in the case of hydraulic fracturing operations, to provide the efficient delivery of proppant deep into remote regions of a fracture and also to provide the non-uniform distribution of proppant by means of particle aggregation, and makes it possible, in the case of gravel packing operations, to maintain circulation of a proppant suspension for the uniform deposition of proppant in the requisite locations in a wellbore. The present invention is intended to solve the problems of creating: a method for modifying the surface of a propping agent during well operations; a method for delivering a propping agent into a subsurface formation; a hydraulic fracturing method; and also a gravel packing method.
