An integrated function metallic block is capable of integrating into a single metal block the functions of valve blocks, block of hydraulic components of the pumping system, channels for transporting produced and separated fluids, flanges for choke connections and sensors, connection fittings and other components capable of being manufactured mutually within a single metallic block. The integrated function block is composed of complex geometry circuits having curves, slants and connections with other channels occurring within the block mass, and is preferably manufactured through the powder metallurgy process of hot isostatic pressing to obtain complex geometries having the lowest possible weight.

An acid-generating fluid includes a thermally activated strong acid precursor. The thermally activated strong acid precursor can include a component selected from aldehydes, ketones, and combinations thereof, in combination with a precursor of a compound adapted to react to liberate sulfur dioxide; or it can include sulfur dioxide in combination with a precursor of a compound adapted to react to liberate a component selected from aldehydes, ketones, and combinations thereof.

There is provided an apparatus 30 and method for conditioning the flow of a mixed phase flow from a supply pipe 101 from a hydrocarbon well. The apparatus 30 comprises an elongate reservoir 11 having a first end for receiving a multi-phase fluid flow from the supply pipe and a second closed end, there being provided a gas outlet 02 from the upper part of the first end, a liquid separation region downstream of the first end, and a liquid outlet 12 from the lower part of the liquid separation region; and a gas-liquid mixer to which the gas and liquid outlets are connected such that the separated gas and liquid may be recombined. The reservoir 11 may accommodate surges of liquid such that the flow rate from the liquid outlet is relatively invariant over time compared to that of the flow received by the apparatus.

A system for emergency response to a well control incident is disclosed, which includes a capture device fitted to a subsea wellhead, a pipeline termination unit fluidly connected to the capture device, and a subsea module fluidly connected to the pipeline termination unit via a subsea flowline, wherein the subsea module comprises a subsea separator, and wherein the subsea module is anchored to a seabed. The system also includes a mini spar fluidly connected to the subsea module by a riser system.

The disclosure discloses a solid fluidization tubular separator for marine natural gas hydrate, which includes a first separator and a second separator, wherein the first separator includes the first separation sleeve, the power liquid pipe, the swirl baffle, the recovery mechanism and the sand discharge mechanism. After the hydrate is sucked into the first separation sleeve to generate a circumferential velocity, so that the mud and sand with high density are separated to the pipe wall of the first separation sleeve, and the mud and sand separated to the pipe wall are settled down from the gap between the swirl baffle and the pipe wall along the pipe wall. The hydrate swirl flows into the recovery mechanism, and then leaves the first separation sleeve and enters the second separator, so as to realize the separation of mud and sand and natural gas hydrate.
