    摘要: A non-flashing fluid sampler for use in obtaining a well fluid sample. The sampler comprises a body defining a first chamber, a second chamber, a third chamber and a sampling port therein. The sampling port is in communication with the first chamber and with an outside zone outside the body. The second and third chambers are initially isolated from one another by a control valve. Upon activating the control valve, fluid may flow from the second chamber to the third chamber through a flow restriction. An extendable floating piston is disposed between the first and second chambers, and the floating piston defines a variable volume therein. An initial amount of well fluid flows into the variable volume, thus trapping dirty fluid, and subsequently, a well fluid sample is flowed into the first chamber. An isolation valve is provided for allowing hydrostatic pressure into the sampler after the fluid sample has been taken. Check valves prevent outward fluid flow from the sampler and thereby trap the hydrostatic pressure therein. Methods of use of the sampling apparatus are also disclosed.

    摘要: Methods of draw-down and build-up testing on existing production wells are disclosed. The testing may be accomplished without removing the production tubing string from the well. The production of the well is shut down and then a coiled tubing test string is run down into the production tubing string. The coiled tubing test string includes a coiled tubing string, a tester valve carried by the coiled tubing string, and a test packer carried by the coiled tubing string. The test packer is set within one of the casing bore and the production tubing bore above perforations which communicate the casing bore with a subsurface formation. Draw-down and build-up testing of the subsurface formation can then be accomplished by opening and closing the tester valve to selectively flow well fluid up through the coiled tubing string or shut in the coiled tubing string. After the draw-down/build-up testing is completed, the coiled tubing test string is removed from the well and production of the well is resumed up through the production tubing bore of the production tubing string. Optionally, the coiled tubing test string may carry a perforating gun to perforate a new zone of the well which may then be tested.

    摘要: A well tool can include a first oscillator which varies a flow rate of fluid, and a second oscillator which discharges the fluid received from the first oscillator at a variable frequency. A method can include flowing a fluid through a first oscillator, thereby repeatedly varying a flow rate of fluid discharged from the first oscillator, and receiving the fluid from the first oscillator into a second oscillator. A well tool can include a first oscillator including a vortex chamber, and a second oscillator which receives fluid flowed through the vortex chamber.

    摘要: A method of geothermal energy production can include injecting water into a formation, and then automatically decreasing resistance to flow through at least one valve in response to the water changing phase in the formation. A geothermal well system can include a tubular string disposed in a production wellbore, the tubular string including at least one valve, water which flows from an injection wellbore into a formation surrounding the wellbore, and then flows from the formation into the production wellbore as steam, and resistance to flow through the valve decreasing automatically in response to presence of the steam in the production wellbore. Another method of geothermal energy production can include injecting water into a formation from an injection wellbore, the water changing phase in the formation, and then automatically decreasing resistance to fluid flow through at least one valve in response to presence of steam in a production wellbore.
