Abstract
Disclosed is a screen packer assembly for use in filtering hydrocarbons in a wellbore at a subterranean location. The screen-packer assembly connects in a production tubing string and packs off the wellbore and provides an axial filter path for hydrocarbons through the assembly and into the productions tubing.
Claims20
A hydrocarbon fluid filtering apparatus for connection to production tubing in a wellbore at a subterranean location, the apparatus comprising:
- a tubular member configured to connect to the production tubing;
- a longitudinally extending housing mounted outside the tubular member, the member being of a size to form an annular space between the tubular member and the housing and of a size to fit in the wellbore;
- walls forming a chamber on one end of the housing, wherein the chamber is in fluid communication with the interior of the housing and the interior of the tubular member;
- packing on the exterior of the housing;
- and
- a filter in the annular space between the tubular member and the housing, whereby hydrocarbon fluids flowing axially along the wellbore through the annular space flow through the filter.
A method of producing filtered fluid hydrocarbons from a well penetrating a subterranean hydrocarbon bearing formation, comprising the steps of:
- providing a filtering apparatus comprising:
- a tubular non porous housing;
- and
- a filter in the interior of the tubular non porous housing;
- connecting the filtering apparatus to an interior tubular member;
- wherein an annular space is formed between the interior tubular member and the tubular non-porous housing;
- wherein the filter is positioned in the annular space;
- positioning the filtering apparatus and the interior tubular member in the wellbore at a subterranean location;
- contacting a wellbore wall with the filtering apparatus to block flow of hydrocarbon fluids between the wellbore wall and the housing;
- filtering hydrocarbon fluids flowing into the wellbore from the subterranean hydrocarbon bearing formation by passing the hydrocarbon fluids through the filter positioned in the annular space;
- and
- flowing the filtered hydrocarbon fluids into the interior tubular member.
