Publication number: 20160177168Abstract: A composition is described as including a mixture of citrus terpene hydrocarbons and an alcohol ethoxylate. The alcohol ethoxylate is represented by the formula R(C2H4O)nOH, where R is a branched or linear alkyl chain having from 12 to 15 carbons, and n is from 3 to 14. A method of removing pipe dope from a wellbore surface is also described. The method involves contacting the wellbore surface with the composition, and circulating the composition with respect to the wellbore surface. The pipe dope detaches from the wellbore surface and is dispersed in the composition, facilitating its removal.Type: ApplicationFiled: December 17, 2014Publication date: June 23, 2016Inventors: Samuel Danican, John W.

Patent number: 7975764Abstract: A sand consolidation system and a method for use of the system is provided. The consolidation system includes an emulsion having an oil phase and an aqueous phase, wherein the emulsion contains a source of insoluble silica particles and a source of calcium hydroxide, wherein the calcium hydroxide particles are present in the oil phase, and the insoluble silica particles are contained in the aqueous phase. Both types of particles must have average particle sizes which will fit into the pores of the formations.Type: GrantFiled: September 26, 2007Date of Patent: July 12, 2011Assignee: Schlumberger Technology CorporationInventors: Philip F.

Patent number: 7717176Abstract: A permeable cement composition including an aqueous slurry of a hydraulic cement which is based upon a water-immiscible dispersed fluid phase and a hollow particulate material. The hollow particulate material breaks down in the presence of the cement so as to leave voids which together with the dispersed phase create a permeable structure in the cement.Type: GrantFiled: April 20, 2006Date of Patent: May 18, 2010Assignee: Schlumberger Technology CorporationInventors: Samuel Danican, Bruno Drochon, Simon James, Beilin Ding

Patent number: 7459019Abstract: In a process to design high temperature cement sluries, the temperature stable phases (anorthite, wairakite) are selected; aluminum modifiers and silica oxides are added to the dry cement so that the elemental composition of the blend corresponds to the phases selected; the control of the particle size distribution and the relative amount of those minerals allow their addition at high concentration while leaving the slurry easily mixable and pumpable; and the kinetics of the targeted phases formation is then controlled by adjusting the crystallinity and the particles sizes of the different solids.Type: GrantFiled: February 14, 2003Date of Patent: December 2, 2008Assignee: Schlumberger Technology CorporationInventors: Véronique Barlet-Gouedard, Chrystel Cambus, Samuel Danican, Erik Nelson, Bruno Goffe

Patent number: 7111683Abstract: A formation consolidation process is described which comprises injecting into an unconsolidated or poorly consolidated subterranean formation penetrated by a wellbore an aqueous pumpable system comprising an insoluble silica source (e.g., colloidal silica, silica fume or fumed silica) and a source of calcium hydroxide (e.g., aqueous solutions of calcium chloride and sodium hydroxide). The aqueous system may contain a nucleation inhibitor. The components of the aqueous system react to produce a calcium silicate hydrate gel (C-S-H gel) having cementitious properties within the pores of the formation. After the C-S-H gel sets and hardens, the consolidated formation has a high compressive strength (e.g., 500 psi (about 3.5 MPa) or more). The technique can be performed as a remedial treatment or in new completions, but it is particularly useful in workover treatments for existing wells.Type: GrantFiled: June 14, 2004Date of Patent: September 26, 2006Assignee: Schlumberger Technology CorporationInventors: Erik B. Nelson, Samuel Danican, Golchehreh Salamat

Patent number: 7013973Abstract: It is proposed a method for completing an unconsolidated interval, including particulates, in a subterranean formation, including a consolidation steps. The consolidation step is performed by injection of an aqueous solution of colloidal particles with a pH modifier and/or an ionic-strength modifier. A hard gel is formed that holds the particulates together. The consolidation is followed by hydraulic fracturing. Diversion towards area of less permeability may be enhanced by the use of micrometric particles.Type: GrantFiled: November 11, 2003Date of Patent: March 21, 2006Assignee: Schlumberger Technology CorporationInventors: Samuel Danican, Golchehreh Salamat, Alejandro Pena, Erik Nelson
