Patent number: 7942215Abstract: Compositions including relatively low reactivity acids, mixed with viscoelastic surfactants (VESs) and internal breakers may serve as drilling fluids to open underground hydrocarbon reservoirs with carbonate contents of 10 wt % or above. The drilling fluids have low viscosities in the drilling pipe. After the fluid flows out of the drill bit, the acids react with carbonates in the formation thereby increasing the pH of the drilling fluids causing the VES to gel the fluid at the bottom of the hole and the downhole annulus between the drilling pipe and the formation rock. The viscosified drilling fluid will reduce fluid loss and will carry no dissolved drilling debris to the surface. After drilling through the targeted formation, the internal breakers in the viscosified drilling fluids will break down the fluids to permit their removal, and the well is ready to produce with very little or no near well bore damage.Type: GrantFiled: October 27, 2009Date of Patent: May 17, 2011Assignee: Baker Hughes IncorporatedInventors: Tianping Huang, James B.

Patent number: 7942219Abstract: PCD constructions include a PCD body comprising a polycrystalline matrix region, a first region that includes a replacement material positioned remote from a body surface, and a second region that is substantially free of the replacement material and that extends a depth from the body surface. The PCD construction can further include a substrate that is attached to the body. The PCD body is formed by removing a solvent catalyst material used to form the body, replacing the removed solvent catalyst material with a replacement material, and then removing the replacement material from a region of the body to thereby form the second region. The replacement material can be introduced into the PCD body during a HPHT process, and the substrate may or may not be the source of the noncatalyzing material.Type: GrantFiled: March 21, 2007Date of Patent: May 17, 2011Assignee: Smith International, Inc.Inventors: Madapusi K.
