Patent number: 9896612Abstract: Method for controlling lost circulation in a subterranean well using oil-dispersible lost-circulation materials which comprise fibers that are coated (or sized) with a lipophilic coupling agent, a lipophilic film-forming polymer or both. The fibers are preferably between about 6 mm and about 25 mm long, and between about 10 ?m and about 200 ?m in diameter. The fibers may be added to carrier fluids comprising oil-base fluids, synthetic-base fluids, invert-emulsion-base fluids and combinations thereof. The preferred fiber concentration in the carrier fluid is between about 0.55 g/L and about 28.5 g/L. The carrier fluid may be a drilling fluid, a spacer fluid or a lost-circulation pill.Type: GrantFiled: December 3, 2010Date of Patent: February 20, 2018Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Slaheddine Kefi, Jesse C.

Patent number: 9790420Abstract: Lipophilic fibers are effective media for cleaning non-aqueous fluids out of a subterranean wellbore. The fibers are preferably added to a drilling fluid, a spacer fluid, a chemical wash, a cement slurry or combinations thereof. Non-aqueous fluids, such as an oil-base mud or a water-in-oil emulsion mud, are attracted to the fibers as they circulate in the wellbore.Type: GrantFiled: August 3, 2012Date of Patent: October 17, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Stephane Boulard, Jesse C.

Publication number: 20160208567Abstract: Methods for curing lost circulation in a subterranean well comprise the use of a first and a second lost circulation material. The first lost circulation material is added during the initial preparation of a process fluid. The second process fluid is added to the process fluid at a later time as the process fluid is being pumped into the subterranean well. The first lost circulation may comprise granular or lamellar particles or both. The second lost circulation material may comprise fibers, ribbons or both.Type: ApplicationFiled: August 18, 2014Publication date: July 21, 2016Inventors: Juan Carrasquilla, Ramata Diarra, Arnoud Willem Meyer, Jesse C.

Publication number: 20150159080Abstract: The following describes a novel and alternative mechanism in regards to releasing reactive chemicals. Namely, utilizing shells containing multiple emulsions that can be blended with the base fluids, and then react with said base fluid upon exposure to a trigger e.g. high shear and/or elongation flow, therefore plugging even large fractures. Such gelling lost circulation material allows to obtain a reliable carrier and fast reaction when triggered.Type: ApplicationFiled: February 17, 2015Publication date: June 11, 2015Inventors: Jesse C.

Publication number: 20150041134Abstract: A cement slurry composition is described as having cement, water, and organic polymer particles. The composition also includes non-ionic surfactants, which may contain ethoxylate groups or contain both ethoxylate groups and propoxylate groups in the hydrophilic part. The non-ionic surfactant acts to disperse the hydrophobic polymeric particles in the slurry, thereby reducing mixing time. The cement slurry composition is prepared and then pumped into the subterranean well and placed in a zone of the subterranean well. Time is then allowed for the cement slurry composition to set and form a solid mass in the zone.Type: ApplicationFiled: September 11, 2014Publication date: February 12, 2015Inventors: Clara Carelli, Jesse C. Lee, Syed A. Ali, Isabelle Couillet, Claire Giraudeau

Patent number: 8776882Abstract: Mixtures of fibers and solid particles are effective for curing fluid losses and lost circulation in a subterranean well. Stiff fibers are more effective than flexible ones; however, mixtures of stiff and flexible fibers have a synergistic effect. The quantity and particle-size distribution of the solids are optimized according to the stiffness, dimensions and concentrations of fibers.Type: GrantFiled: January 6, 2013Date of Patent: July 15, 2014Assignee: Schlumberger Technology CorporationInventors: Nikhil Shindgikar, Jesse C.

Patent number: 8093187Abstract: Composition and method for shortening the shear recovery time of cationic, zwitterionic, and amphoteric viscoelastic surfactant fluid systems by adding an effective amount of a co-gelling agent selected from triblock oligomeric compounds having hydrophilic (for example polyether) and hydrophobic (for example alkyl) portions. The co-gelling agent also increases fluid viscosity and very low co-gelling agent concentration is needed. Preferred surfactants are betaines and quaternary amines. The fluids are useful in oilfield treatments, for example fracturing and gravel packing.Type: GrantFiled: January 17, 2008Date of Patent: January 10, 2012Assignee: Schlumberger Technology CorporationInventors: Yiyan Chen, Jesse C.

Patent number: 7879770Abstract: Compositions and methods are given for delayed breaking of viscoelastic surfactant gels inside formation pores, particularly for use in hydraulic fracturing. Breaking inside formation pores is accomplished without mechanical intervention or use of a second fluid. Oxidizing agents such as air, oxygen, persulfates, bromates, peroxides, and others are used. The break may be accelerated, for example with a free radical propagating species, or retarded, for example with an oxygen scavenger. In certain brines, for example bromide brines, certain zwitterionic viscoelastic fluid systems that can decarboxylate and that require an anion-containing co-surfactant undergo delayed degradation if oxygen is present, for example from fluid preparation or in a foam.Type: GrantFiled: September 18, 2006Date of Patent: February 1, 2011Assignee: Schlumberger Technology CorporationInventors: Lijun Lin, Yiyan Chen, Philip F. Sullivan, Belgin Baser, Carlos Abad, Jesse C. Lee

Patent number: 7857051Abstract: A composition and method for improving the fluid efficiency of many oilfield treatments is given. The composition is a solid additive, in a viscosified fluid, in a size range small enough that it enters formation pores; it optionally bridges there to form an internal filter cake, and then decomposes to provide a breaker for the viscosifying system for the fluid. Examples of suitable additives include waxes, polyesters, polycarbonates, polyacetals, polymelamines, polyvinyl chlorides, and polyvinyl acetates. Degradation of the additive may be accelerated or delayed.Type: GrantFiled: March 15, 2010Date of Patent: December 28, 2010Assignee: Schlumberger Technology CorporationInventors: Carlos Abad, Jesse C.
