Patent number: 8727003Abstract: An ultra-lightweight, high strength ceramic proppant made from mixture of naturally occurring clays, preferably porcelain clay, kaolin and/or flint-clay, earthenware clay or other naturally occurring clays having an alumina content between about 5.5% and about 35%. The proppant has an apparent specific gravity from about 2.10 to about 2.55 g/cc, and a bulk density of from about 1.30 to about 1.50 g/cc. This ultra-lightweight proppant is useful in hydraulic fracturing of oil and gas wells, and has greater conductivity than sand at pressures up to 8,000 psi as measured by Stim-Lab after 50 hours and 275° F. on Ohio Sandstone, in the presence of deoxygenated aqueous 2% solution of KCI.Type: GrantFiled: July 23, 2010Date of Patent: May 20, 2014Assignee: Prop Supply and Service, LLCInventors: Ying Li, Zhijie Huang, Shengming Lin, Wenzhong Wu

Patent number: 8728991Abstract: The present invention relates to lightweight high strength microsphere containing ceramic particles having controlled microsphere placement and/or size and microsphere morphology, which produces an improved balance of specific gravity and crush strength such that they can be used in applications such as proppants to prop open subterranean formation fractions. Proppant formulations are further disclosed which use one or more microsphere containing ceramic particles of the present invention. Methods to prop open subterranean formation fractions are further disclosed. In addition, other uses for the microsphere containing ceramic particles of the present invention are further disclosed, as well as methods of making the microsphere containing ceramic particles.Type: GrantFiled: December 23, 2010Date of Patent: May 20, 2014Assignee: Oxane Materials, Inc.Inventors: Shanghua Wu, Yuming Xie, Christopher E.

Publication number: 20140131038Abstract: The present invention relates to methods and compositions that can be used to delay crystallization of a treatment solution so that thief zones or fractures are plugged in subterranean formations at a substantial distance from a wellbore. A supersaturated sodium aluminate solution, or other solutions, is introduced into the reservoir. The solution is relatively stable in the supersaturated state. Crystallization, or de-stabilizing the solution, can be controlled, which in turn plugs the thief zone or fracture at a designed point of time. By controlling the time that crystallization starts, that is, the induction period, thief zones that are located at a substantial distant from the wellbore can be plugged.Type: ApplicationFiled: January 17, 2014Publication date: May 15, 2014Applicant: Saudi Arabian Oil CompanyInventors: Xianmin Joe Zhou, Yun Chang
