Patent number: 8490686Abstract: A method of mitigating perforating effects produced by well perforating can include causing a shock model to predict perforating effects for a proposed perforating string, optimizing a compliance curve of at least one proposed coupler, thereby mitigating the perforating effects for the proposed perforating string, and providing at least one actual coupler having substantially the same compliance curve as the proposed coupler. A well system can comprise a perforating string including at least one perforating gun and multiple couplers, each of the couplers having a compliance curve, and at least two of the compliance curves being different from each other. A method of mitigating perforating effects produced by well perforating can include interconnecting multiple couplers spaced apart in a perforating string, each of the couplers having a compliance curve, and selecting the compliance curves based on predictions by a shock model of shock generated by the perforating string.Type: GrantFiled: October 1, 2012Date of Patent: July 23, 2013Assignee: Halliburton Energy Services, Inc.Inventors: John P.

Patent number: 8395010Abstract: The present invention provides devices and methods for treating wounds. The devices may include polymer particles capable of absorbing fluid such as blood. When devices of the invention are exposed to fluid, the fluid may enter the device and cause the polymer particles to swell. Devices of the invention may also apply pressure on wound cavities to stop or restrict the flow of fluid. In some embodiments, the devices may comprise components to facilitate absorption of fluid throughout the device, such as wicking elements and/or multiple compartments. One or more of the devices can be placed directly in the wound cavity, or in a containment structure and then into the wound cavity.Type: GrantFiled: November 22, 2010Date of Patent: March 12, 2013Assignee: FEG Holdings, LLCInventors: Javier de Luis, Marco Serra, Timothy Sutherland, Liping Sun
