摘要： A method and system is shown to passively monitor cement integrity within a wellbore. Different types of sensors (pressure, temperature, resistivity, rock property, formation property etc.) are “pumped” into place by placing them into a suspension in the cement slurry at the time a well casing is being cemented. The sensors are either battery operated, or of a type where external excitation, (EMF, acoustic, RF etc.) may be applied to power and operate the sensor, which will send a signal conveying the desired information. The sensor is then energized and interrogated using a separate piece of wellbore deployed equipment whenever it is desired to monitor cement conditions. This wellbore deployed equipment could be, for example, a wireline tool.

摘要： A whipstock and whipstock anchor that allows for select orientation of the whipstock, retrievability of the whipstock, and also resetting of the whipstock in select orientation. The whipstock is for use in drilling a cased subterranean well with a drill bit. The whipstock includes a first device that directs the drill bit. The first device is supported at a desired location along the well casing by a second device. The first device and second device incorporate mechanisms that allow selective orientation of the first device with respect to the second device. The orientation of the second device in its location along the well casing can be accurately detected, and the mechanisms that allow selective orientation of the first device with the second device can be adjusted to provide an accurate, desired orientation for diverting a drill bit or other tool as it contacts the first device. The first device of the whipstock is retrievable and may be run multiple times to the same wellbore location to provide multiple orientations for creating wellbore bends and branching.

摘要： A downhole power generator produces electrical power for use by downhole tools. In a described embodiment, a downhole power generator includes a member that is vibrated in response to fluid flow through a housing. Vibration of the member causes a power generating assembly to generate electrical power.

摘要： A downhole force generator includes a longitudinal force generating and transmitting assembly (including, for example, a motor and a threaded shaft that is extended and retracted by operation of the motor) adapted to be moved into a well. A controller is also adapted to be moved into the well and is connected to the longitudinal force generating and transmitting assembly. The controller includes a memory containing a program to control the longitudinal force generating and transmitting assembly to obtain at least one desired operating condition in the well. A sensor can be connected to the controller. A self-contained power source adapted to be moved into the well can also be used. A method of providing an infinitely variable linear force in an oil or gas well is a particular application for such a downhole force generator. This particular method comprises sensing in the well a parameter responsive over a continuum to changes in a selected operating condition in the well. This method further comprises actuating a microcontroller to run a predetermined program stored in the microcontroller. The program is run to obtain a specific state of the selected operating condition represented within the continuum of the sensed parameter.
