A well drilling method can include transporting a pressure optimization unit to a rig site, the pressure optimization unit including a choke manifold, a control system which automatically controls operation of the choke manifold, and a flowmeter which measures flow of drilling fluid through the choke manifold, and then interconnecting the pressure optimization unit to rig drilling equipment. A pressure optimization unit for use with a well drilling system can include a choke manifold, a control system which automatically controls operation of the choke manifold, and a flowmeter which measures flow of drilling fluid through the choke manifold. The choke manifold, control system and flowmeter may be incorporated into a same conveyance which transports the pressure optimization unit to a rig site.
82 METHODS, SYSTEMS, AND COMPUTER-READABLE MEDIA FOR REAL-TIME OIL AND GAS FIELD PRODUCTION OPTIMIZATION USING A PROXY SIMULATOR EP07762832.9 2007-01-31 EP1982046B1 2011-03-30 CULLICK, Alvin, Stanley; JOHNSON, William, Douglas
Methods, systems, and computer readable media are provided for real-time oil and gas field production optimization using a proxy simulator. A base model (30) of a reservoir (100), well (100), pipeline network (100), or processing system (100) is established in one or more physical simulators (26). A decision management system (24) is used to define control parameters, such as valve settings (410), for matching with observed data (114). A proxy model is used to fit the control parameters to outputs of the physical simulators (26), determine sensitivities of the control parameters, and compute correlations between the control parameters and output data from the simulators (26). Control parameters for which the sensitivities are below a threshold are eliminated. The decision management system (24) validates control parameters which are output from the proxy model in the simulators (26). The proxy model may be used for predicting future control settings for the control parameters.

An apparatus and method for obtaining samples of pristine formation or formation fluid, using a work string designed for performing other downhole work such as drilling, workover operations, or re-entry operations. An extendible element extends against the formation wall to obtain the pristine formation or fluid sample. While the test tool is in a standby condition, the extendible element is withdrawn within the work string, protected by other structure from damage during operation of the work string. The apparatus is used to sense or sample downhole conditions while using a work string, and the measurements or samples taken can be used to adjust working fluid properties without withdrawing the work string from the bore hole. When the extendible element is a packer, the apparatus can be used to prevent a kick from reaching the surface, adjust the density of the drilling fluid, and thereafter continuing use of the work string. The test apparatus can be mounted on a sliding, non-rotating, sleeve on the work string.

91 FIELD/RESERVOIR OPTIMIZATION UTILIZING NEURAL NETWORKS EP01274015.5 2001-03-21 EP1381921A1 2004-01-21 STORM, Bruce, H., Jr.; SCHULTZ, Roger, L.; DENNIS, John, R.; RICHARDSON, John, M.
A method of optimizing performance of a well system utilizes a neural network. In a described embodiment, the method includes the step of accumulating data indicative of the performance of the well system in response to variable influencing parameters. The data is used to train a neural network to model an output of the well system in response to the influencing parameters. An output of the neural network may then be input to a valuing model, e.g., to permit optimization of a value of the well system. The optimization process yields a set of prospective influencing parameters which may be incorporated into the well system to maximize its value.

The present invention relates to a control mechanism for a horizontal drilling machine that uses a drilling rod (2) to drive a drilling lance (1). The control mechanism is provided with an input interface for receiving actual values of control variables of the horizontal drilling machine and fitted with an output unit that emits control signals to control said horizontal drilling machine. A fuzzy regulator (7) is arranged between the input interface and the output unit. Said regulator determines the control signals that control the horizontal drilling machine on the basis of the actual values of the control variables and the desired values for the control variables, using fuzzy logic and taking heuristic process values into account. The control mechanism enables a horizontal drilling device to be operated automatically and provides good line guidance and target accuracy.

A drill string is equipped with a downhole assembly having an instrumented sub and a drill bit (108). The instrumented sub (104) has a power source that requires no electrical chemical batter. A mass-spring system is used, which during drilling causes a magnet to oscillate past a coil. This induces current which is used to power downhole instruments.

Another conductor (40) may also be provided along the continuous tubing string (30) to conduct power from a surface power supply (42) to the control (34). The conductors (38, 40) are preferably housed in the wall of the continuous tubing string (30) and may be electrical conductors, optical fibers, and/or hydraulic conduits. The control (34) is preferably equipped with a sensor that verifies operation and status of the device and provides the verification to the surface processor via the conductor.

96 Drill bit design using neural networks EP00307034.9 2000-08-17 EP1146200A1 2001-10-17 Jelley, David John; Jarvis, Brian Peter

The present invention is a method and apparatus which accurately predicts one or more operating characteristics of an earth boring drill bit operated under a set of known operating conditions. A range of operating conditions may be input so that the operating characteristic(s) of the drill bit may be predicted over, and perhaps beyond the range the drill bit designer has anticipated. In this manner, a new drill bit design may be refined and/or proven with a high level of confidence prior to manufacture. Only minimal field testing of the new design is required to verify its performance.

100 Method for controlling the development of an oil or gas reservoir EP98303548.6 1998-05-06 EP0881357A2 1998-12-02 Stephenson, Stanley V.

Development of an oil or gas reservoir is controlled using a neural network and genetic algorithm program to define a neural network topology and the optimal inputs for that topology. The topology is defined from identified and selected parameters (1) associated with the formation or formations in which actual wells are drilled in the reservoir, and (2) associated with the drilling, completion and stimulation of those wells, and (3) associated with the oil or gas production from the wells. Subsequent drilling, completion and stimulation of the reservoir is determined and applied based on hypothetical alternatives input to the topology and resulting outputs.
