Abstract: An open hole formation surface within a wellbore of a well system is sealed with a polymer seal. A deployment system is inserted into the wellbore to the location of the open hole formation surface. The open hole formation surface may be located at the bottom of the wellbore or at an interval between two casing strings. The deployment system delivers an expandable polymer grout system to the location of the open hole formation surface. The expandable polymer grout system cures to form the polymer seal on the open hole formation surface.

Abstract: Methods for placing an annular pack in a well include treating of the gravel in the annular pack to inhibit bridging and the formation of voids in the annular pack. The gravel can be treated to form a coating that improves the lubricity of the gravel. The gravel also can be treated with a surface-active agent. The treatment of the gravel inhibits clumping of the gravel particles which forms bridges in the annular pack.

Abstract: Methods for assessing the effectiveness of an acid stimulation operation in a hydrocarbon well are described herein. The methods use encapsulated tracer particles comprising a tracer material that is coated with a calcium carbonate shell. Different encapsulated tracer particles are placed into different portions of a well. A subsequent acid stimulation operation dissolves the calcium carbonate shell and releases the tracer material. The different tracer materials indicate the effectiveness of the acid stimulation operation in different portions of the well.

Abstract: The present application pertains to a method of tracing acid stimulation treatment in a hydrocarbon well using one or more coated tracers. The method comprises placing the one or more coated tracers at pre-determined downhole locations in the hydrocarbon well. The well is then acid stimulated and the amount of the tracer in a produced fluid from the hydrocarbon well is measured. The one or more coated tracers each comprise a tracer and a coating which are described herein.

Abstract: A deployment system for deploying a polymer grout system includes a first conduit line for conveying an isocyanate component, a second conduit line for conveying an organic polyol component, and a mixer for mixing the isocyanate component and the organic polyol component to form an expandable polymer grout system that is deployed to a target location associated with a wellbore. The deployment system can include a tailpipe and/or bridge plug for directing the expandable polymer grout system to the target location. The disclosure also includes methods of using the foregoing deployment system.

Abstract: A method of deploying an expandable composition in a cement top job in a well system includes identifying evidence of actual or potential gas migration within an annulus cement of the well system. Once the evidence of gas migration is identified, a first component and a second component are mixed in a mixer to form the expandable composition and the expandable composition is pumped from the mixer through a conduit to a top of cement of the annulus cement. The expandable composition expands to form an expanded composition that seals the annulus above the top of cement of the annulus cement. Cement can be added onto the expanded composition.

Abstract: A method for creating an expandable polymer grout plug within or through a wellbore includes providing an expandable polymer grout system to a target location within or through the wellbore, wherein the expandable polymer grout system comprises: (i) an isocyanate component comprising one or more isocyanate compounds; and (ii) an organic polyol component comprising one or more organic polyol compounds; in the presence of (iii) one or more blowing agents; combining the foregoing components of the expandable polymer grout system to facilitate the polymerization reaction to form the expandable polymer grout plug at the target location; and allowing the expandable polymer grout plug to cure at the target location.

Abstract: An annular blowout preventer includes a body, a piston disposed within the body, and a packing unit disposed adjacent the piston. The packing unit includes an packer body surrounding an opening. The packer body is fabricated from a first material. The packing unit further includes a second material disposed between the packer body and the opening, the second material being less rigid than the first material. The packer body and the second material constrict the opening when the annular blowout preventer is actuated. The second material creates a seal around a tool disposed within the opening. The second material fills in one or more crevices or recesses on an outer perimeter of the tool.
