Abstract: Methods include providing a blowout preventer body having at least one sealing ram for engaging with a downhole tool, and the sealing ram is hydraulically actuatable between a ram open position and a ram closed position. A hydraulic control valve is provided and used for sensing a differential pressure across the at least one sealing ram. The hydraulic control valve is fluidly connected to the blowout preventer body, and the hydraulic control valve operates as a hydraulic interlock to prevent the at least one sealing ram from being moved to the ram open position under predetermined differential pressure conditions. The blowout preventer is connected to a wellhead disposed on a wellbore, and the downhole tool and coiled tubing are deployed into and out of the wellbore.

Abstract: This disclosure provides equipment and processes for ground heat exchange. Embodiments of the ground heat exchange system may comprise a geothermal well that includes an inner tube positioned coaxially inside a borehole in geologic units, a substantially-liquid impermeable outer liner sealed at the bottom, and a liquid supply system. The outer liner may include one or more layers of a substantially-liquid impermeable fabric or coating. A fluid such as water is supplied by the liquid supply system and flows co-axially through the inner tube. The fluid pressure in the annulus between the inner tube and the outer liner presses the outer liner against the borehole wall, providing sealing contact and preventing interconnection of aquifers of the geologic units.

Abstract: A locking core plug includes an upper plate, an insertion portion extending outward from the upper plate and forming an outer perimeter, and a locking mechanism positioned within the outer perimeter of the insertion portion. The locking mechanism includes a rotating member, a plurality of locking arms having a first end connected to the rotating member and a second end extending outward toward holes in the outer perimeter; and a plurality of guides fixedly mounted relative to the upper plate. Each guide engages a corresponding locking arm to convert the circular movement of the first end of the arm as rotating member rotates into an outward movement of the second end from a release position retracted toward or within the outer perimeter of the insertion portion to a locking position extended outward from the outer perimeter of the insertion portion.

Abstract: A device is described for a foundation to be placed in a sea bed, comprising a housing-formed, downwardly open, coat-forming construction set up for placing in the sea bed, said construction comprises a top part, and the top part comprises an extended hollow body (140) that stretches a distance into the inside of the construction. The invention is characterised in that the length of the inner pipe is shorter or longer than the length of the coat. When the inner pipe is shorter, its length is of the order of 10-90% of the length of the skirt 10, preferably 25 to 60%, and most preferred 50%. When the inner pipe is longer, its length is more than 100% and up to 300% of the length of the outer coat (10), preferably 150 to 200% and most preferred 300%. A method and different applications are also described.
