Abstract

There is provided a flow control apparatus configured for optimizing use of available space within the wellbore for conducting of fluids between the surface and the subterranean formation. The flow control apparatus is useable for conducting all forms of fluid, such as, for example, liquids, gases, or mixtures of liquids and gases. As well, the flow control apparatus is useable for effecting injection of fluid (e.g. a fluid for stimulating hydrocarbon production via a drive process, such as, for example, waterflooding, or via a cyclic process, such as “huff and puff”) into the subterranean formation, and for receiving production of fluid (e.g. hydrocarbon material) from the subterranean formation (including production that is stimulated by gas lift).

First claim

The invention claimed is:

1. A flow control apparatus for disposition within a subterranean formation, comprising:
a housing;
a fluid conducting passage defined within the housing;
a flow communicator configured for effecting flow communication between the fluid conducting passage and the subterranean formation, wherein the flow communicator includes:
an orifice defined within a valve seat;
one or more ports defined within the outermost surface of the housing; and
a space extending between the orifice and the one or more ports;

a flow control member displaceable relative to the valve seat between seated and unseated positions for controlling flow communication via the orifice; and
a cutting tool coupled to the flow control member for translation with the flow control member; wherein:
the flow control member and the cutting tool are co-operatively configured such that, while: (i) the flow control member is being displaced relative to the valve seat between the seated and the unseated positions, and (ii) solid debris is disposed within the space, the cutting tool effects size reduction of the solid debris, such that size-reduced solid debris is obtained.

2. The flow control apparatus as claimed in claim 1 , wherein:
the flow control member and the cutting tool are further co-operatively configured such that, while the flow control member is being retracted relative to the valve seat, the obtained size-reduced solid debris is urged into the fluid passage.

3. The flow control apparatus as claimed in claim 2 , wherein the urging is effected by the cutting tool.

4. The flow control apparatus as claimed in claim 1 , wherein the cutting tool includes a reamer.

5. The flow control apparatus as claimed in claim 1 , wherein:
the flow control member, the valve seat, the orifice, the space extending from the orifice to the one or more ports, and the cutting tool are co-operatively configured such that, while the flow control member is unseated relative to the valve seat, and the cutting tool is disposed within the space, the cutting tool occupies less than about 70% of the cross-sectional area of the space.

6. A flow control apparatus for disposition within a subterranean formation, comprising:
a housing;
a fluid conducting passage defined within the housing;
a flow communicator configured for effecting flow communication between the fluid conducting passage and the subterranean formation, wherein the flow communicator includes:
an orifice defined within a valve seat;
one or more ports defined within the outermost surface of the housing; and
a space extending between the orifice and the one or more ports;

a reciprocating assembly including a flow control member that is displaceable relative to the valve seat between seated and unseated positions for controlling flow communication via the orifice;
wherein:
the flow control member and a distal end of the reciprocating assembly are co-operatively configured such that
while the flow control member is seated relative to the valve seat, the distal end, of the reciprocating assembly, extends through the orifice and into the space, while being spaced apart from the housing, and is spaced apart from the housing by a maximum distance of less than 30/1000 of an inch; and
wherein the distal end is defined by a cutting tool.

7. A flow control apparatus for disposition within a subterranean formation, comprising:
a housing;
a fluid conducting passage defined within the housing;
a flow communicator configured for effecting flow communication between the fluid conducting passage and the subterranean formation, wherein the flow communicator includes:
a port defined within the outermost surface of the housing; and
a flow communication passage extending between the fluid-conducting passage and the port;
an orifice disposed within the flow communication passage between the fluid-conducting passage and the port, and defined within a valve seat;

a flow control member displaceable relative to the valve seat between seated and unseated positions for controlling flow communication via the orifice; and
wherein:
the orifice defines a central axis;
the port defines a central axis;
the orifice and the port are co-operatively configured such that, while the flow control apparatus is oriented such that the central axis of the orifice is disposed within a horizontal plane, the central axis of the port is disposed at an acute angle of greater than 45 degrees relative to the horizontal plane; and
the orifice is disposed within a space between the fluid-conducting passage and the port, and the apparatus comprises a tracer material source disposed within the space.

8. The flow control apparatus as claimed in claim 7 , wherein:
the orifice and the port are co-operatively configured such that, while the flow control apparatus is oriented such that the central axis of the orifice is disposed within a horizontal plane, the central axis of the port is normal, or substantially normal, to the horizontal plane.

9. The flow control apparatus as claimed in claim 7 , wherein:
the fluid passage defines a central longitudinal axis; and
the orifice and the fluid passage are co-operatively configured such that, while the flow control apparatus is oriented such that the central axis of the orifice is disposed within a horizontal plane, the central longitudinal axis of the fluid passage is disposed at an acute angle of less than 45 degrees relative to the horizontal plane.

10. The flow control apparatus as claimed in claim 7 , wherein:
the fluid passage defines a central longitudinal axis; and
the orifice and the fluid passage are co-operatively configured such that, while the flow control apparatus is oriented such that the central axis of the orifice is disposed within a horizontal plane, the central longitudinal axis of the fluid passage is parallel, or substantially parallel, to the horizontal plane.

11. A flow control apparatus for disposition within a subterranean formation, comprising:
a housing;
a fluid conducting passage defined within the housing;
a flow communicator for effecting flow communication between the fluid conducting passage and the subterranean formation;
a flow control member displaceable, relative to the flow communicator, between closed and open positions, for controlling flow communication between the fluid conducting passage and the flow communicator;
a hydraulic actuator for effecting the displacement of the flow control member; wherein:
the hydraulic actuator includes:
working fluid;
a pump;
a first working fluid containing space;
a second working fluid containing space; and
a piston

each one of the first and second working fluid containing spaces, independently, is disposed in fluid pressure communication with the piston;
the working fluid, the pump, the piston, the first space, and the second space are co-operatively configured such that:
while the flow control member is disposed in one of the opened and closed positions, and the pump becomes disposed in the first mode of operation, the pump is receiving supply of working fluid from the first working fluid containing space and discharging pressurized working fluid into the second working fluid containing space, with effect that working fluid, within the second working fluid containing space, and in fluid pressure communication with the piston, becomes disposed at a higher pressure than working fluid within the first working fluid containing space and in fluid pressure communication with the piston, such that an unbalanced force is acting on the piston and effects movement of the piston, such that the flow control member is displaced to the other one
