Abstract: In one aspect, embodiments disclosed herein relate to a wellbore strengthening composition including at least one polymer capable of polymerizing through a free radical polymerization reaction from the group of epoxy acrylates, modified epoxy acrylates, epoxy precursors, modified epoxy vinyl esters, unsaturated polyesters, urethane (meth)acrylates, polyester acrylates, epoxy vinyl ester resins having the formula (I), wherein R and R1-R5 may be CH3— or H and R6-R21 may be H or Br, and polymer combinations thereof; and at least one initiator, wherein the resin is present in the amount from about 10 to about 90 weight percent.

Abstract: A centrifuge, including: a flange closing off one axial end of a separation chamber; a plurality of apertures that traverse axially through the flange at a radial distance from a flange axis, wherein at least one aperture is in fluid communication with a first outlet passage; a plurality of weir inserts removably disposed within the plurality of apertures to control a flow of one or more fluids from the separation chamber; wherein at least one weir insert disposed within the at least one aperture in fluid communication with the first outlet passage is changeable to prevent or allow fluid communication between the separation chamber and the first outlet passage.

Abstract: A method of cleaning a wellbore drilled with an oil-based drilling fluid that forms an oil-based filter cake may include: emplacing a breaker fluid into the wellbore, the breaker fluid comprising: a water-miscible non-aqueous fluid; at least one weighting salt; and at least one breaking agent; and shutting in the well for a period of time sufficient to initiate breaking of the oil-based filter cake.

Abstract: An apparatus for recovery of solids from a vapor, the apparatus including: a vessel comprising a cylindrical portion on top of an angled portion; a vapor inlet located in the cylindrical portion for introducing a solid-vapor mixture tangentially to the cylindrical portion; at least one inlet nozzle disposed in a top of the vessel for spraying a hydrocarbon fluid into the vessel; an indirect heat exchange device disposed concentrically within the cylindrical portion, thereby providing an annulus for vapor and hydrocarbon flow; a heat exchange device disposed at an exterior of the angled portion; an outlet located at a bottom of the angled portion to recover the vapor having a reduced solids content and a solid-hydrocarbon mixture. Also disclosed are processes to clean an oil vapor using such an apparatus.

Abstract: A method of recovering formate from halide-contaminated formate brine that includes mixing a formate recovery solvent and the halide-contaminated formate brine; separating halide contaminants from the formate; and recovering the formate from the formate recovery solvent is disclosed.

Abstract: A method of operating a shaker including: disposing a shaker screen in a shaker, wherein the shaker screen includes at least one tag selected from the group consisting of a radio frequency identification tag and a surface acoustic wave tag; reading shaker screen information from the at least one tag; and adjusting at least one shaker variable using the shaker screen information. In another aspect, embodiments relate to a shaker screen including: a filtering element disposed on a frame; wherein the frame includes: at least one outer frame member; at least one cross member; and at least one tag selected from the group consisting of a radio frequency identification tag and a surface acoustic wave tag; wherein at least a portion of the tag is integral with at least one of an outer frame member and a cross member. Also disclosed is a method of manufacturing a shaker screen having an integral tag.

Abstract: A wellbore fluid having at least two phases, the wellbore fluid including a fluid phase; and a solid phase including a powdered solid material coated with a polymer, wherein the polymer is the reaction product of a polyesteramide and a crosslinking agent is disclosed.
