    Abstract: A composition and method is given for a well control fluid that is injected into a well during completion or remediation and prevents fluid flow from a formation into the well during operations (such as shut-in, or placement or adjustment of tools/hardware) when no fluid flow is desired. The composition includes a viscoelastic surfactant fluid system (VES) and a decomposable first solid material, preferably in fiber form, that forms a pack or plug in the well at the location where fluid would otherwise leak off, and then decomposes without intervention to release a product that is a breaker for the surfactant or the micelles of the VES. The composition optionally also contains a pH control agent and a second solid (that may also be a fluid loss agent) that affect the decomposition of the first solid.

    Abstract: A composition for treatment of a subterranean formation, which may be used for water control, is comprised of at least one of 1) a premix of an oleochemical polyol, at least one of polyisocyanate, polycyanate and polyisothiocyanate, and a blocking agent to temporarily block all or a portion of free reactive groups of said at least one of polyisocyanate, polycyanate and polyisothiocyanate. Alternatively, or in addition, the composition may be comprised of a solvent and 2) a polyurethane prepolymer formed by reacting an oleochemical polyol and at least one of polyisocyanate, polycyanate and polyisothiocyanate. A blocking agent may also be used with the polyurethane prepolymer. The composition may be used in a method of treating a subterranean formation penetrated by a wellbore by introducing the composition into the formation through the wellbore. In another embodiment, a method of treating a subterranean formation penetrated by a wellbore is carried out by forming a treatment fluid containing at least one of 1) palmitic acid or its derivatives and 2) palm oil and at least one of an hydrolyzing or oxidizing agent to facilitate formation of palmitic acid or its derivatives. The treatment fluid also includes a source of a monovalent ions. The treatment fluid is introduced into the wellbore for treatment of the subterranean formation.

    Abstract: A delayed gelling system useful in conformance control in the production of petroleum from subterranean formations is disclosed. The gelling system comprises an acidic aqueous solution of acid-soluble or cationic polyacrylamide, an at least partially neutralized acid aluminum salt, an activator comprising a hydroxyl donor, and an optional gel modifier. The gelling system may be pumped into formations with excessive water production and thermally activated in the formation at downhole conditions to form a co-gel of polyacrylamide interspersed in an inorganic gel network to reduce water production.

    Abstract: A switching matrix and testing platform may enable controlled testing of various configurations of radio access networks (RANs) at various signal strengths. The switching matrix and testing platform may enable testing of the radio frequency (RF) signals from RANs or telecommunications devices for new and/or predetermined scenarios, such as using different configurations of the RANs at various signal strengths. During a scenario, various operations may be performed on the telecommunications device in communication with the tested RF signals, such as making voice calls, transmitting and receiving data (messages, videos, music, etc.). A performance of the telecommunications device and/or various telecommunication network elements may be analyzed in comparison to other telecommunications device and/or various telecommunication network elements.

    Abstract: A wellbore cleaning device comprises a tubular section, a helical scratcher mounted thereon. The helical scratcher contains flexible wires characterized in that the helical scratcher is able to rotate axially to the tubular section when a fluid flows axially to the tubular section. A method for using the device comprises placing the device into the wellbore; allowing the fluid flowing axially to the wellbore wall to rotate the scratcher; removing a deposit at wellbore wall; and leaving a cleaned wellbore wall.
