195 Downhole production well control system and method US385992 1995-02-09 US5732776A 1998-03-31 Paulo S. Tubel; Albert A. Mullins, II; Kevin R. Jones; Frank D. Richardson
A downhole production well control system is provided for automatically controlling downhole tools in response to sensed selected downhole parameters. An important feature of this invention is that the automatic control is initiated downhole without an initial control signal from the surface or from some other external source. This control system generally comprises downhole sensors, downhole electromechanical devices and downhole computerized control electronics whereby the control electronics automatically control the electromechanical devices based on input from the downhole sensors. Thus, using the downhole sensors, the downhole computerized control system will monitor actual downhole parameters (such as pressure, temperature, flow, gas influx, etc.) and automatically execute control instructions when the monitored downhole parameters are outside a selected operating range (e.g., indicating an unsafe condition). The automatic control instructions will then cause an electromechanical control device (such as a valve) to actuate a suitable tool (for example, actuate a sliding sleeve or packer; or close a pump or other fluid flow device). The downhole control system of this invention also includes transceivers for two-way communication with the surface as well as a telemetry device for communicating from the surface of the production well to a remote location.

197 Kelly-to-riser position determining system with adjustment for uncompensated heave US55451 1987-05-28 US4852052A 1989-07-25 James E. Frey; William Stohrer-Hoyt
A system for determining kelly-to-riser position on floating drilling platforms is presented. The system removes (e.g. filters) uncompensated heave from surface sensor measurements so that bit depth can be accurately calculated. During operation, surface sensors on the drilling platform measure heave compensator action and kelly movements. Each heave sensor reading is then added to a kelly sensor reading in order to obtain a value termed kelly-to-riser. Each kelly-to-riser value is fed (inputted) into the system of the present invention and a filtered reading is returned for use in calculating bit depth and rate of penetration (ROP). The filtering system is termed a linear extrapolative filter (LEF). The LEF generates filtered readings by performing a linear regression on measurements taken over its pre-specified filter interval. It then predicts the current kelly-to-riser position from the resultant trend line.
198 Adaptive riser angle position reference system US177667 1980-08-13 US4351027A 1982-09-21 Tom A. Gay; Gary L. Hartman; Gunter Stein
An adaptive riser angle position reference system and method for determining the horizontal position of a marine vessel relative to an underwater wellhead from angular deviations from vertical of a riser between the vessel and the wellhead are disclosed. The system comprises sensors for determining deviation from vertical of the riser at positions proximate the wellhead and the vessel and a compensation filter for adaptively filtering signals indicative of the lower and upper riser angles in accordance with filter coefficients which are determined by riser parameters. The filter coefficients are established by riser parameter identification means which effectively compares riser response, as indicated by the lower and upper riser angles, with the responses of a plurality of riser models, and selects filter coefficients corresponding to the most accurate model.
199 Riser angle positioning system and process US125804 1980-02-28 US4317174A 1982-02-23 Q. Wayne Dean
A riser angle positioning system and process provides information for dynamically positioning a floating vessel having a riser extending to a wellhead on the ocean floor. The system comprises an acoustic system for generating acoustic data signals representing the position of the vessel with respect to the wellhead, top and bottom riser inclinometers for generating respective sensor signals indicating angles of deflection of the riser at the top and bottom, respectively, thereof, and a processor responsive to the acoustic data signals and the sensor signals for generating positioning information. The riser angle positioning system and process serve as a backup system and method for checking the acoustic data for large errors, and additionally provide the sole position determining system and method in case of acoustic blackout. The riser angle positioning system and process have two alternative modes of operation: a simulator mode during which the vessel position is calculated from data read from a dynamic positioning system magnetic tape log, and a real time mode during which data is read directly from analog-to-digital converters associated with the top and bottom inclinometers and the acoustic system.
200 Wireline stabilization method and apparatus US13958 1979-02-22 US4252190A 1981-02-24 Alfred H. Jageler; Theodore V. Lautzenhiser
Downhole variations in wireline cable tension are substantially reduced for offshore exploration by means of an auxiliary cable tensioning system preferably installed at the ocean floor wellhead. Part of the lifting force applied to a wireline cable is provided by the wireline stabilization tool at the wellhead so that fluctuations in wireline tension above the wellhead caused by ocean disturbances on the floating platform will be effectively filtered out and isolated from the main cable downhole from the wellhead. This downhole isolation is achieved with a moving wireline as well as with a stationary cable.
