    摘要： A method for recovering connate fluids (e.g. oil) from a low permeability subterranean reservoir (e.g. diatomite) through a single wellbore. Upper and lower intervals are fractured from the wellbore that the fractured intervals only partially overlap, thereby leaving a partial, natural barrier formed of random-spaced, low permeable areas along the interface between the fractured intervals. This partial barrier improves the sweep efficiency of a drive fluid (e.g. water) which is injected into the lower fractured interval by forcing it to spread outward into the reservoir before it is flows through the upper fractured interval. The drive fluid is injected at approximately the same rate as that at which the fluids are produced so that displacement of oil occurs primarily due to imbibition.

    摘要： Provided are gas processing facilities for the separation of components in a gas stream and methods of using the same. The facility includes one or more co-current contactors. Each contactor includes a mass transfer vessel having a mixing section. The mixing section receives a gas stream and a liquid contacting stream. The mixing section mixes theses two streams and releases a two-phase flow. Each contactor also includes a separator that receives the two-phase fluid stream from the mass transfer vessel in-line, and then separates a vapor phase from a liquid phase. The separator has a gas-phase outlet configured to release the vapor phase as a treated gas stream, and a liquid-phase outlet configured to release the liquid phase as a loaded treating solution. The contactors may be used to remove water or other contaminant from a natural gas stream or other gas stream.

    摘要： A method and apparatus for treating steam which is to be injected into a formation through a gravel pack well completion by preventing dissolution and removal of silica from the gravel pack. The steam is flowed through a treatment vessel which is filled with a silica-containing material, e.g. sand, where it dissolves silica from the sand prior to injection through the gravel pack. Since the treated steam is already substantially saturated with silica, it will not dissolve any substantial amounts of silica from the gravel pack. The treatment vessel can also be heated during treatment, if desired.
