Definitions
- the present disclosure relates generally to dummy valves. More specifically, in certain embodiments the present disclosure relates to hydraulic lock compensating dummy valves for use in gas lift and associated methods and systems.
- Gas-lift wells have been in use since the 1800's and have proven particularly useful in increasing efficient rates of oil production where the reservoir natural lift is insufficient.
- natural gas produced in the oil field is compressed and injected in an annular space between the casing and tubing and is directed from the casing into the tubing to provide a "lift" to the tubing fluid column for production of oil out of the tubing.
- the tubing can be used for the injection of the lift-gas and the annular space used to produce the oil, this is rare in practice.
- One common type of gas-lift well uses mechanical, bellows-type gas-lift valves attached to the tubing to regulate the flow of gas from the annular space into the tubing string. Examples of such gas-lift valves are described in U.S. Patent Nos. 5,782,261 and 5,425,425, the entireties of which are hereby incorporated by reference.
- the bellows is preset or pre-charged to a certain pressure such that the valve permits communication of gas out of the annular space and into the tubing at the pre-charged pressure.
- each valve is selected by a well engineer depending upon the position of the valve in the well, the pressure head, the physical conditions of the well downhole, and a variety of other factors, some of which are assumed or unknown, or will change over the production life of the well.
- Dual pocket side pocket mandrels are often used in offshore wells where it is desired or required that there must be no communication between the tubing and the annular space during the act of gas lift valve intervention.
- the dual pocket mandrel allows for the operating gas lift valve to be pulled while leaving the barrier isolation valve in place thus allowing for now communication of tubing to annular.
- the act of pulling the operating valve out of its pocket in the mandrel may allow for the introduction of tubing fluid into the valve pocket and space between the operating valve and barrier isolation valve. Once the operating valve is replaced with a traditional dummy valve the issue of hydraulic locking may exist.
- the fluid trapped in the space between the barrier isolation valve and the dummy valve, being non-compressible, may not allow for the remainder of the dummy valve to be driven into its pocket.
- Traditional dummy valves have no means of dealing with this trapped fluid.
- the present disclosure relates generally to dummy valves. More specifically, in certain embodiments the present disclosure relates to hydraulic lock compensating dummy valves for use in gas lift and associated methods and systems.
- the present disclosure provides a dummy valve comprising: a housing and a rupture disc disposed within the housing, wherein the housing and the rupture disc define a first internal chamber.
- the present disclosure provides a gas lift system comprising: a gas lift mandrel comprising a first pocket and a second pocket; a gas lift valve disposed within the first pocket; and a dummy valve disposed within the second pocket, wherein the dummy valve comprises a housing and a rupture disc disposed within the housing, wherein the housing and the rupture disc define a first internal chamber.
- the present disclosure provides a method comprising: providing a gas lift mandrel, wherein the gas lift mandrel comprises a first pocket and a second pocket and placing a dummy valve within the second pocket, wherein the dummy valve comprises a housing and a rupture disc disposed within the housing, wherein the housing and the rupture disc define a first internal chamber.
- Figure 1 illustrates a dummy valve in accordance with certain embodiments of the present disclosure.
- Figure 2 illustrates a gas lift mandrel in accordance with certain embodiments of the present disclosure.
- the present disclosure relates generally to dummy valves. More specifically, in certain embodiments the present disclosure relates to hydraulic lock compensating dummy valves for use in gas lift and associated methods and systems.
- dummy valves discussed herein may provide a means to deal with trapped liquid in dual pocket mandrels.
- Other potential advantages of the dummy valves discussed herein are that they do not rely on shear pins, thus minimizing the chances of damaging the dummy valve when reinstalling it into the pocket.
