    摘要： A valve assembly can include a flow passage extending between an uphole end and a downhole end of the valve assembly, a flapper that pivots between an open position and a closed position, and a pump operable to pivot the flapper, the pump being positioned between the flapper and the downhole end. A method of testing a completion tubing string can include increasing pressure in the completion tubing string while a closure member of a valve assembly is in a closed position, thereby testing a pressure integrity of the completion tubing string on an uphole side of the closure member, and transmitting a pressure signal via a flow passage to a pressure sensor of the valve assembly, thereby causing the closure member to displace to an open position, the pressure sensor being connected to an electronic circuit positioned on a downhole side of the closure member.

    摘要： A method of pressure testing a well tool can include applying positive or negative pressure to an internal chamber of the well tool, or determining a reference pressure, and monitoring the pressure in the internal chamber using a pressure sensor in the internal chamber. Another method can include applying pressure to an internal chamber of a well tool at a surface location, thereby creating a pressure differential in one direction across a seal, and installing the well tool in a well, thereby creating another pressure differential in a possibly opposite direction across the seal. A well system can include a well tool including an internal chamber, and a pressure sensor disposed in the chamber, whereby the pressure sensor detects pressure within the chamber.

    摘要： Blowout preventers, fluid pressure systems and portions thereof may be tested for leaks by calculating an Apparent Compressibility Factor which is determined during initial pressurization of the system to the test pressure. The equivalent decay rate is calculated by measuring the amount of intensifying fluid required to be added to maintain the system at the test pressure level. The equivalent decay rate in psi per minute is then compared to the acceptable decay rate for the pressure level of the test to determine if the system passed the test.

    摘要： An example tool for testing a wellbore includes a body having a longitudinal dimension configured for insertion into a casing of the wellbore, and a packer disposed along the body. The packer is controllable to expand against an inner diameter of the casing to enable testing the wellbore. The example tool also includes a scraper assembly disposed along the body for arrangement downhole of the packer when the body is inserted into the casing.

    摘要： An offshore universal riser system may include a valve module which selectively permits and prevents fluid flow through a flow passage extending longitudinally through a riser string. An anchoring device may releasably secure the valve module in the passage. A method of constructing a riser system may include the steps of installing the valve module in the passage, and installing at least one annular seal module in the passage. The annular seal module may prevent fluid flow through an annular space between the riser string and a tubular string positioned in the passage. Drilling methods may include injecting relatively low density fluid compositions into the annular space, and selectively varying a restriction to flow through a subsea choke in a drilling fluid return line. The riser string, including housings for the various modules and external control systems, may be dimensioned for installation through a rotary table.
