Publication number: 20120255728Abstract: 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, are 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, i.e., the induction period, thief zones that are located at a substantial distant from the wellbore can be plugged.Type: ApplicationFiled: April 11, 2011Publication date: October 11, 2012Applicant: Saudi Arabian Oil CompanyInventors: Xianmin Joe Zhou, Yun Chang

Patent number: 8281859Abstract: Methods and compositions are disclosed that comprise cement kiln dust having a mean particle size that has been altered. An embodiment discloses a subterranean treatment method comprising: introducing a treatment fluid into a subterranean formation, wherein the treatment fluid comprises cement kiln dust having a mean particle size that has been altered from its original size by grinding, separating, or a combination thereof. Another embodiment discloses a subterranean treatment method comprising: introducing a treatment fluid into a subterranean formation, wherein the treatment fluid comprises cement kiln dust having a mean particle size that has been reduced from its original size.Type: GrantFiled: February 17, 2012Date of Patent: October 9, 2012Assignee: Halliburton Energy Services Inc.Inventors: Craig W. Roddy, Jiten Chatterji, Chad Brenneis, Callie R. Jarratt

Publication number: 20120247765Abstract: Disintegrative particles are designed to be blended with and pumped with typical proppant materials, e.g. sand, ceramics, bauxite, etc, into the fractures of a subterranean formation. With time and/or change in wellbore or environmental condition, these particles will either disintegrate partially or completely, in non-limiting examples, by contact with downhole fracturing fluid, formation water, or a stimulation fluid such as an acid or brine. Once disintegrated, the proppant pack within the fractures will lead to greater open space enabling higher conductivity and flow rates. The disintegrative particles may be made by compacting and/or sintering metal powder particles, for instance magnesium or other reactive metal or their alloys. Alternatively, particles coated with compacted and/or sintered nanometer-sized or micrometer sized coatings could also be designed where the coatings disintegrate faster or slower than the core in a changed downhole environment.Type: ApplicationFiled: March 26, 2012Publication date: October 4, 2012Applicant: Baker Hughes IncorporatedInventors: Gaurav Agrawal, James B. Crews, Zhiyue Xu

Publication number: 20120252706Abstract: A well treatment composite comprising a well treatment agent adsorbed onto a water-insoluble adsorbent may be prepared by precipitating the well treatment agent, in the presence of a metal salt, from a liquid while the well treatment agent is being adsorbed onto the water-insoluble adsorbent. After a treatment fluid containing the composite is introduced into a well or a subterranean formation, the well treatment agent is slowly released from the composite. The composite permits a continuous supply of the well treatment agent into a targeted area and is particularly effective in high pH treatment fluids.Type: ApplicationFiled: March 30, 2011Publication date: October 4, 2012Inventor: WILLIAM H.

Patent number: 8278251Abstract: Water flood materials may contain an effective amount of a nano-sized particulate additive to inhibit or control the movement of fines within a subterranean formation during a water flood secondary recovery operation. The particulate additive may be an alkaline earth metal oxide, alkaline earth metal hydroxide, alkali metal oxide, alkali metal hydroxide, transition metal oxide, transition metal hydroxide, post-transition metal oxide, post-transition metal hydroxide, piezoelectric crystal, and/or pyroelectric crystal. The particle size of the magnesium oxide or other agent may be nanometer scale, which scale may provide unique particle charges that help control and stabilize the fines, e.g. clays.Type: GrantFiled: July 14, 2009Date of Patent: October 2, 2012Assignee: Baker Hughes IncorporatedInventor: Tianping Huang

Patent number: 8278373Abstract: Use of two different methods, either each by itself or in combination, to enhance the stiffness, strength, maximum possible use temperature, and environmental resistance of such particles is disclosed. One method is the application of post-polymerization process steps (and especially heat treatment) to advance the curing reaction and to thus obtain a more densely crosslinked polymer network. The other method is the incorporation of nanofillers, resulting in a heterogeneous “nanocomposite” morphology. Nanofiller incorporation and post-polymerization heat treatment can also be combined to obtain the benefits of both methods simultaneously. The present invention relates to the development of thermoset nanocomposite particles.Type: GrantFiled: January 19, 2012Date of Patent: October 2, 2012Assignee: Sun Drilling Products CorporationInventors: Jozef Bicerano, Robert L.
