    摘要： A system to identify one or more species of interest within drilling fluid. The system comprises a heat exchanger (110) including a first tubular (121) and a second tubular (122), wherein each tubular has an inlet and an outlet. The system also comprises: a supply line (101) coupled to the inlet of the first tubular; a return line (102) coupled to the outlet of the second tubular; a drilling fluid heater (140) having an inlet (141) coupled to the outlet of the first tubular and an outlet (142); and a drilling fluid degasser (150) having an inlet (152) coupled to the outlet (142) of the heater, a first outlet (153) coupled to an analyzer (160) configured to identify the one or more species of interest, and a second outlet (154) coupled to the inlet of the second tubular. The heat exchanger is configured to transfer thermal energy from the drilling fluid flowing through the second tubular to the drilling fluid flowing through the first tubular.

    摘要： The present invention relates to the use of a downhole pumping tool for removing a hydrate formation forming a hydrate plug in a tubing in a well, the downhole pumping tool comprising a pump having a pump inlet and a pump outlet, an electric motor for driving the pump, a wireline for powering the electric motor, the pump having a first end arranged closest to the wireline and a second end facing the hydrate plug, wherein the pump inlet is arranged in the second end, and the pump inlet contacts a first face of the hydrate plug, the pump providing suction to remove at least part of a plurality of gas molecules from the hydrate plug for dissolving at least part of the hydrate formation. The invention also relates to a hydrate removal method for removing hydrate formation forming a hydrate plug in a tubing.
