Patent number: 8122950Abstract: Wellbore strengthening during drilling may be achieved by including chemicals in the drilling fluid that can be polymerised when exposed to microwave energy. Selected chemicals are mixed with the drilling fluid but do not react with it. The chemicals concentrate in a filter cake on the borehole wall during drilling-fluid circulation. A tool, which comprises a microwave source, is used to trigger polymerisation or crosslinking reactions within the filter cake. The polymerisation or crosslinking reactions cause the formation of a film or gel that strengthens the wellbore.Type: GrantFiled: April 8, 2009Date of Patent: February 28, 2012Assignee: Schlumberger Technology CorporationInventors: Sylvie Daniel, Mickael Allouche

Patent number: 7779915Abstract: Methods for treating a formation penetrated by a wellbore which improves fluid loss control during treatment. In some aspects, the treatments include preparing an aqueous fluid including one or more water inert degradable polymers and an optional viscosifier, injecting the aqueous fluid into the wellbore at a pressure equal to or greater than the formation's fracture initiation pressure, and thereafter injecting into the wellbore a proppant laden fluid at a pressure equal to or greater than the formation's fracture initiation pressure. The water inert degradable polymer may be a polymer such as an emulsion polymer or a latex polymer. Some methods of the invention use a fluid which may have a normalized leak off coefficient (Cw/sqrt(K)) equal to or less than about 0.0022, 0.0014, or 0.0010. A conventional fluid loss additive may or may not be used in conjunction with the treatment fluid and/or the proppant laden fluid. The water inert degradable polymer may or may not substantially enter formation pores.Type: GrantFiled: June 13, 2008Date of Patent: August 24, 2010Assignee: Schlumberger Technology CorporationInventors: Richard D.
