Patent number: 8183179Abstract: A method for treating a subterranean formation includes forming a treatment fluid including a carrier fluid, a solid acid-precursor, and a solid scale inhibitor. The solid acid-precursor includes a material that forms an acid at downhole conditions in the subterranean formation. The method further includes adding a solid acid-responsive material into the treatment fluid, where the solid acid-responsive material enhances formation of acid from the solid acid-precursor in acidic conditions. The method includes performing an acid fracture treatment and inhibiting scale formation within the subterranean formation. The solid scale inhibitor allows for long-term scale inhibition after the treatment.Type: GrantFiled: February 11, 2011Date of Patent: May 22, 2012Assignee: Schlumberger Technology CorporationInventors: Marieliz Garcia-Lopez De Victoria, John W.

Patent number: 7950462Abstract: Methods are given for making scale inhibitors, that were previously incompatible with fluids containing fluoride ion, compatible with fluids containing fluoride ion. Examples of such scale inhibitors include phosphonates and phosphino-polycarboxylates. The method is replacing alkali metal and alkaline earth metal cations, present in salts or bases, or as counter ions of the scale inhibitors, with hydrogen or ammonium ions. Methods of inhibiting scale formation and of dissolving scales are also given.Type: GrantFiled: April 23, 2010Date of Patent: May 31, 2011Assignee: Schlumberger Technology CorporationInventors: Zhijun Xiao, Marieliz Garcia-Lopez de Victoria, Francis Tuedor

Patent number: 7770644Abstract: A method is described for treating a subterranean formation with a low viscosity fluid system that contains a viscoelastic surfactant at a concentration too low to viscosify the fluid, but that is concentrated in the formation so that the fluid system gels. The fluid optionally contains a formation-dissolving agent. The fluid is used in matrix acidizing, acid fracturing, and diversion.Type: GrantFiled: June 27, 2007Date of Patent: August 10, 2010Assignee: Schlumberger Technology CorporationInventors: Diankui Fu, Mohan Panga, Slaheddine Kefi, Marieliz Garcia-Lopez de Victoria

Publication number: 20090038799Abstract: A treatment fluid for a subterranean formation includes a carrier fluid and an amount of particles including a granular scale inhibitor. The carrier fluid includes a hydratable gel fluid, a crosslinked gel fluid, an acid-based fluid, an oil-based fluid, and/or a visco-elastic surfactant. The particles include a proppant impregnated with the scale inhibitor, a solid particle formed largely from the scale inhibitor, or both. The proppant includes scale inhibitor adsorbed on porous surfaces within the proppant, and/or a porous proppant with scale inhibitor embedded in the bulk porosity of the proppant. The scale inhibitor is present in an amount between about 1% and 5% of a total weight of particles. The particles include scale inhibitor at a sufficient concentration and dissolution rate to provide acceptable scale inhibitor concentrations in produced fluids for production volumes exceeding 500 pore volumes.Type: ApplicationFiled: July 17, 2008Publication date: February 12, 2009Inventors: Marieliz Garcia-Lopez de Victoria, Curtis Sitz, Bernhard Lungwitz, Baudel William Quintero, Leonardo Maschio, Jack Li

Publication number: 20080146465Abstract: An acidic viscoelastic surfactant fluid composition is formulated with an acid, for example hydrochloric acid, a cationic surfactant, for example a quaternary amine, and a break-enabling salt, for example NH4Cl. The fluid composition has low viscosity as formulated, undergoes an increase in viscosity as the acid is consumed when it reacts with an acid-reactive material, and returns to approximately the initial viscosity as the last of the acid is consumed. The fluid composition is used as a diverting fluid or as the main treatment fluid in oilfield treatments such as matrix acidizing and acid fracturing.Type: ApplicationFiled: February 28, 2008Publication date: June 19, 2008Inventors: Diankui Fu, Marieliz Garcia-Lopez De Victoria
