Abstract: The present invention provides apparatus and methods for handling fluids returning from a well. The fluids are introduced into a separator and a separated gas stream is recovered or recycled. The gas stream may comprise more than one phase. The separated gas stream is urged through a multiphase pump before it is recovered. Alternatively, the return fluids may pass through a multiphase pump before it is introduced into the separator.

Abstract: The present invention generally relates to an apparatus and method for removing hydrocarbons and other material from a wellbore. In one aspect, a method of drilling a sub-sea wellbore is provided. The method includes circulating a drilling fluid through a drill string from a surface of the sea to a drill bit in the wellbore. The method further includes pumping the fluid and drill cuttings from the sea floor to the surface with a multiphase pump having at least two plungers operating in a predetermined phase relationship. In another aspect, a fluid separator system having a first and a second plunger assembly is provided. The fluid separator system includes at least one fluid line for removing a fluid portion from the at least one plunger assembly and at least one gas line for removing gas from the first and a second plunger assembly.

Abstract: The present invention generally relates to a well servicing system for cleaning out of a well in which a compressed inert gas, produced by the non-cryogenic separation of air is delivered to the region of the well where particulate matter has collected that inhibits the ability of the well to produce.

Abstract: The present invention generally relates to a system and method for using a gas in a well. In one aspect, the system includes a source of fluid and at least one multiphase pump for transporting the fluid. The system further includes a separator for separating phases in the fluid and an injector for injecting the gas into the well. The gas may be used for kicking off a shut-in well by the simultaneous injection of the gas into the shut-in well and the reduction of the wellhead pressure. The gas may also be used for maintaining production of the well, cleaning out the well or lightening the wellbore fluid in riser system. In another aspect, the invention provides a portable multiphase pump system. In yet another aspect, the invention provides a method for recycling gas from a wellbore fluid.

Abstract: There is disclosed a method for cleaning out of a well in which a compressed inert gas, produced by the non-cryogenic separation of air is delivered to the region of the well where particulate matter has collected that inhibits the ability of the well to produce.
