摘要: A method for treating a subterranean formation penetrated by a wellbore is provided. The method includes providing a treatment fluid containing a viscoelastic surfactant having at least one degradable linkage, a hydrolysable material, and a pH control material, and injecting the treatment fluid into a subterranean formation. The pH control material may have a pH equal or greater than about 9 and may include a strongly alkaline material and an oxidizing agent.

摘要: A method and system for recovering data written onto a storage device when system failure and/or damage occur during use is provided. A memory of the storage device is divided into a plurality of information zones, for storing data as a codeword set, and a plurality of check zones, for storing checksums, of equal size selected from different parts of the storage device. A computing unit calculates etalon checksums with an established formula during each write data operation for each codeword set in the information zones. If failure, damage or data corruption occurs, computing unit calculates current checksums using an established formula. The values of the stored etalon checksums and the current checksums are used for data recovery, which is performed by solving the system of equations, received from the formula for computing the checksums. Parallel calculation schemes are used in checksum computing and for data recovery.
