International Classification:

E21B043/12

US Classification:

166142, 166373, 166194

Abstract:

One embodiment of the present disclosure describes a test assembly including an inflatable packer. An internal control sleeve controls flow of drilling fluid through an inflation port to inflate and deflate the packer. A shifting tool run on a slick line moves the sleeve. The packer has one end attached to an external sliding sleeve which moves upon packer inflation to expose a formation fluid port through which formation testing is performed. After testing and packer deflation, a circulation port may be opened to recover produced fluids up the drill string. A second sleeve controls flow through the circulation port and is controlled by a second shifting tool run on slick line. Other embodiments include a circulation assembly with a sliding sleeve opened and closed by one shifting tool to control circulation and the sliding sleeve itself and its operation.

Abstract:

A single phase fluid sampler system and associated methods. A fluid sampling method includes the steps of: receiving a fluid sample into a sample chamber of a fluid sampler; pressurizing the fluid sample using a pressure source; and increasing pressure in the pressure source while the pressure source is in the well, thereby applying increased pressure to the fluid sample in the sample chamber. Another method includes the step of applying pressure to the well to thereby increase pressure in the pressure source, and to thereby increase pressure on the fluid sample. A fluid sampler system includes a fluid sampler with a sample chamber, a pressure source for pressurizing the sample chamber, and a device which operates to increase pressure in the pressure source while the fluid sampler is in the well.
