Abstract
A valve useful in an inflow control device for downhole use in an oil and gas well completion equipment is disclosed. The valve may have a flexible canopy that prevents fluid flow between the base pipe and the formation when flow travels in a first direction and permits fluid flow between the base pipe and the formation when flow travels in a second direction.
Claims15
A valve assembly for use in downhole completion equipment comprising:
- a valve block having at least one fluid passage opening and a valve stem opening;
- and
- a valve having a valve stem, a valve retention member at a first proximate end of the valve stem, and a flexible valve canopy at a second end of the valve stem, the canopy having a fluid sealing surface;
- wherein the valve stem is arranged in the valve stem opening of the valve block and the fluid sealing surface covers the at least one fluid passage opening to prevent fluid flow when fluid flows in a first direction through the at least one fluid passage opening and uncovers the at least one fluid passage opening when fluid flows in a second direction, the valve operable to be removed from the valve stem opening while the valve assembly is downhole, to provide bidirectional flow.
1 more element
An inflow control device for use in downhole completion equipment comprising:
- a base pipe having an interior and at least one fluid flow port;
- an outer housing arranged on the base pipe;
- a fluid flow control assembly arranged within the outer housing having a fluid flow passage way that permits the flow of hydrocarbon containing fluid from an oil-bearing subterranean formation to the interior of the base pipe through the at least one fluid flow port;
- and
- a valve arranged in the fluid flow passage way capable of restricting the flow of fluid from the subterranean formation to the interior of the base pipe, the valve having a flexible canopy that prevents fluid flow between the base pipe and the formation when flow travels in a first direction and permits fluid flow between the base pipe and the formation when flow travels in a second direction, the valve operable to be removed from the fluid flow passage way while the inflow control device is downhole, to provide bidirectional flow.
2 more elements
A well system comprising:
- a production tubing string;
- a wellbore having a substantially horizontal section;
- at least one well screen assembly interconnected in the tubular string and positioned in the horizontal section of the wellbore;
- an uncased section in the horizontal section of the wellbore;
- at least one packer for isolating a fluid production zone of the wellbore;
- an inflow control device for downhole use in an oil and gas well, the inflow control device including a base pipe having an interior and at least one fluid flow port;
- an outer housing arranged on the base pipe;
- a fluid flow control assembly arranged within the outer housing having a fluid flow passage way that permits the flow of hydrocarbon containing fluid from an oil-bearing subterranean formation to the interior of the base pipe through the at least one fluid flow port;
- and
- a valve arranged in the fluid flow passage way capable of restricting the flow of fluid from the subterranean formation to the interior of the base pipe, the valve having a flexible canopy that prevents fluid flow between the base pipe and the formation when flow travels in a first direction and permits fluid flow between the base pipe and the formation when flow travels in a second direction.
