    摘要： A method and drilling fluid system for providing filtration control during drilling operations using a drilling fluid system comprising water soluble polymer comprising acrylamide monomer, the method comprising: providing a drilling fluid system having effective rheological properties, the drilling fluid system comprising aqueous base consisting essentially of freshwater, a quantity of from about 21 to 58 kg/m3 (7.5 to about 20 pounds per barrel) plugging agent, and an amount of bridging agent comprising water soluble polymer comprising acrylamide monomer which exhibits a 5% by weight Brookfield viscosity in freshwater of from about 50 cP to about 100 cP, and; contacting a subterranean formation with the drilling fluid system and maintaining effective filtration control at concentrations of about 10,000 ppm or less monovalent salt, as demonstrated in the laboratory by producing a HPHT filtrate of 25 cm3/min or less after 30 minutes at about 149° C. (300° F.) after static aging of said drilling fluid system for a period of 16 hours or more at temperatures of about 260° C. (500° F.).

    摘要： Methods, systems, and computer program products are provided for recovering from false positives of malware detection. Malware signatures that are defective may be causing false positives during software scanning for malware. Such defective malware signatures may be detected (e.g., by user feedback, etc.) and revoked. Computers that are using the malware signatures to detect malware may be notified of the revoked signatures, and may be enabled to re-scan content identified as containing malware using malware signatures that do not include the revoked malware signatures. As such, if the content is determined during the re-scan to not be infected, the content may be re-enabled for usage on the computer (e.g., may be restored from quarantine storage).
