摘要： Early evaluation testing of a subsurface formation is provided by monitoring pressure fall-off in the formation. This is accomplished by providing a column of fluid in the well having an overbalanced, hydrostatic pressure at the subsurface formation greater than a natural formation pressure of the subsurface formation. A testing string is run into the well, and the testing string includes a packer, a pressure monitor and a closure tool arranged to close a bore of the testing string. The formation is shut in by setting the packer and closing the bore of the testing string with the closure tool and thereby initially trapping the overbalanced hydrostatic pressure of the column of fluid in the well below the packer. Then the pressure in the well below the packer is monitored as it falls off toward the natural formation pressure. This data can be extrapolated to estimate the natural formation pressure based upon a relatively short actual test interval on the order of ten to fifteen minutes.
摘要翻译：通过监测地层中的压力下降来提供地下地层的早期评估试验。这通过在井中提供一列流体在地下地层处具有超过地下地层的天然地层压力的过平衡静水压力来实现。测试字符串运行到井中，测试串包括封隔器，压力监视器和用于封闭测试串的孔的闭合工具。通过设置封隔器并用封闭工具封闭测试柱的孔，从而最初将流体柱的流体静压力初始地捕获在封隔器下面的井中，从而关闭地层。然后在封隔器下面的井中的压力随着朝向天然地层压力的下降而被监测。该数据可以外推，以基于十到十五分钟的相对短的实际测试间隔来估计天然地层压力。

摘要： A hydraulic control and actuation system for downhole tools. In a described embodiment, a hydraulic control and actuation system includes an internal chamber serving as a low pressure region and a well annulus serving as an energy source. A valve assembly provides selective fluid communication between alternating opposite sides of a piston and each of the energy source and low pressure region. Displacement of the piston operates a well tool. Operation of the valve assembly is controlled via telemetry between a remote location and an electronic circuit of the system.

摘要： A test, drill and pull system for testing a well formation or zone of interest and further drilling of the well in a single trip into the wellbore. The system includes a surface readout tester valve, a rotation-operated reversing valve, a resettable packer, a packer lockout, a perforated anchor and a drill bit. In operation, the apparatus is run into the bottom of the well adjacent to the formation or zone of interest and the packer set and unset as desired. With the packer set, a surface readout tester valve probe is lowered into the apparatus on a wireline and latched into the tester valve so that multiple testing operations may be carried out if desired. After testing, the fluid recovery may be reversed out and analyzed by actuating the reversing valve by rotation of the tool string. Further, rotation engages the packer lockout such that when weight is picked upon the packer, the packer cannot be reset. After the packer lockout is engaged and the packer unset, further drilling operations may be carried out without removing the apparatus from the wellbore.
