Patent number: 7589050Abstract: An aqueous oilfield treatment fluid containing a chelating agent and an HF source is described. This fluid is effective at dissolving siliceous materials such as clays and keeping the dissolved materials in solution. In particular it is effective at preventing re-precipitation of initially-dissolved silicon as silica and therefore reduces damage to sandstones with which it is contacted. Methods are given for using this fluid for sandstone matrix stimulation, removal of clay-containing drilling fluid components and filter cakes from wellbores, sandstone acid fracturing, and gravel pack and proppant pack cleaning.Type: GrantFiled: February 9, 2007Date of Patent: September 15, 2009Assignee: Schlumberger Technology CorporationInventors: Wayne Frenier, Murtaza Ziauddin, Stephen Davies, Frank Chang

Patent number: 7540328Abstract: A dry solid composition is disclosed that, when added to an aqueous liquid, provides a slurry that can be used in sandstone acid fracturing. The slurry generates hydrofluoric acid downhole to etch the sandstone fracture faces created. The chemical and physical properties of the composition result in very uneven etching of the fracture faces, enhancing the fluid conductivity of the final fracture. Optionally, inert masking materials may be included in the dry composition, or added to the slurry, to increase the inhomogeneity of the etching and further increase the fluid conductivity.Type: GrantFiled: September 20, 2007Date of Patent: June 2, 2009Assignee: Schlumberger Technology CorporationInventors: J. Ernest Brown, John W. Still, Diankui Fu, Zhijun Xiao, Wayne Frenier

Publication number: 20060272816Abstract: Proppants for treating subterranean which are scale resistant as well as fluids containing and methods of using such proppants. The proppant materials are less susceptible to fouling by residual materials in the fracturing or gravel pack fluid and hence may have improved clean-up compared with conventional materials. Long-term scale deposition during well production may also be improved. Proppant materials according to the invention are typically used in conjunction with carrier fluids or formation treatment fluids, such as fracturing treatments, for placement in the formation or wellbore penetrating the formation.Type: ApplicationFiled: May 22, 2006Publication date: December 7, 2006Inventors: Dean Willberg, Erik Nelson, Wayne Frenier
