  • Publication number: 20090260806
    Abstract: A bottomhole tool and a method for optimizing oil production rate from an oil well with high gas-to-oil ratio and stabilizing thereof in case of occurrence of a gas cone or gas skin conditions are disclosed. The resistance of the adjustable multi-stage flow resistor is determined by a position of a telescoping needle, which in turn is defined by a driving means including a motor and a gearbox. The motor is driven via a cable from a surface by a control means adapted to receive information about the bottomhole parameters from local sensors via a sensor cable. Methodology explaining the principles of maintaining well stability is also disclosed. Automatic adjustment of the bottomhole pressure is maintained over a wide range of operating parameters throughout the life of the well to maximize its oil output.

  • Publication number: 20090250210
    Abstract: A device and method can detect, and also break, an occurrence of gas lock in an electrical submersible pump assembly in a well bore based upon surface or downhole data without the need for operator intervention. To detect an occurrence of gas lock, an instantaneous value is monitored using a sensor. Then a controller compares the instantaneous value to a threshold value over a predetermined duration to thereby detect the occurrence of gas lock in the electrical submersible pump assembly. Sensors can include, for example, a differential pressure gauge, a pressure gage located in a pump stage located toward the inlet, a fluid temperature sensor located toward the discharge, a free gas detector located near the pump discharge, an electrical resistivity gage, a flow meter located within surface production tubing, and a vibration sensor attached to a tubing string to measure a vibration signature.

  • Publication number: 20090218103
    Abstract: A method for flow control and a self-adjusting valve or flow control device, in particular useful in a production pipe for producing oil and/or gas from a well in an oil and/or gas reservoir, which production pipe includes a lower drainage pipe preferably being divided into at least two sections each including one or more inflow control devices which communicates the geological production formation with the flow space of the drainage pipe. The fluid flows through an inlet (10) and further through a flow path of the control device (2) passing by a movable disc (9) or movable device which is designed to move relative to the opening of the inlet and thereby reduce or increase the flow-through area (A2) by exploiting the Bernoulli effect and stagnation pressure created over the disc (9), whereby the control device, depending on the composition of the fluid and its properties, automatically adjusts the flow of the fluid based on a pre-estimated flow design.

  • Publication number: 20090032237
    Abstract: A shape memory material is used for a power spring in a subsurface safety valve. The spring is sized for the force it will deliver when it goes past its transition temperature and reverts to an original shape. The force released by having the spring pass its transition temperature holds the valve closed against hydrostatic pressure. Since the force exerted by the spring does not increase as the valve opens less force is required to hold the valve in the open position, thus lowering opening pressure. The trigger to cross the transition temperature comes from the expected temperature of well fluids at the mounting position of the subsurface safety valve. Other downhole applications are anticipated.

Sensors are used to monitor at least one downhole property in real time. Based on the real time data, the continuous feedback system enables adjustments to be made with respect to the at least one property in a manner designed to influence a downhole event.

  • Publication number: 20080257546
    Abstract: Autonomous control of a wellbore tool is provided by programming a memory module of a processor with a database having data relating to a selected parameter of interest; conveying a sensor and the processor along the wellbore; and activating the wellbore tool if the processor determines that a measurement provided by the sensor correlates with the database data. The processor may correlate the sensor measurements with a predetermined pattern associated with the data, a preset value, and/or a preset range of values. Well tool activation may occur when the processor finds: a substantial match between a predetermined pattern and at least one measured value; a present value and at least one measured value, and/or a preset range of values and at least one measured range of values. Also, activating the well tool may occur only if a measurement from a second sensor meets a preset criteria.

  • Patent number: 7434619
    Abstract: A method and associated apparatus continuously optimizes reservoir, well and surface network systems by using monitoring data and downhole control devices to continuously change the position of a downhole intelligent control valve (ICV) (12) until a set of characteristics associated with the “actual” monitored data is approximately equal to, or is not significantly different than, a set of characteristics associated with “target” data that is provided by a reservoir simulator (32). A control pulse (18) having a predetermined signature is transmitted downhole thereby changing a position of the ICV. In response, a sensor (14) generates signals representing, “actual” monitoring data. A simulator (32) which models a reservoir layer provides “target” data.

  • Publication number: 20080164021
    Abstract: New methods and systems for subterranean fracturing for hydrocarbon wells. A plan of the fracture propagation and in-fracture proppant distribution is used with a real-time model of the status of the fracture dimensions and in-fracture proppant concentration to automatically control flow rates and properties of a fracturing fluid flow stream being used to induce and prop the fracture. Real-time measurements of the status of the fracture are made using surface and/or down-hole sensors. Real-time control over the flow rate and properties of a fracturing fluid flow stream are made by manipulating the fracturing fluid supply equipment. Real-time modifications of the fracturing model are made by comparing fracture sensor measurements of actual fracture dimensions to the predicted dimensions, and then adjusting the model for inaccuracies. Real-time updates to the fracturing plan are made by comparing actual fracture and propping results to desired results, and then adjusting to achieve optimal results.

  • Publication number: 20080149323
    Abstract: A screen section has a valve assembly to control flow through it. The valve is open and has a closure spring held compressed by a shape memory material that responds to the presence of a specific well fluid or fluids so that its property changes to allow the spring to deliver the stored potential energy to the valve member to close it when the specific well fluid or fluids are detected. The preferred material is a shape memory polymer that, for example, is sensitive to the presence of water or methane and gets softer to release the potential energy source to operate the downhole tool.

  • Patent number: 7389814
    Abstract: An apparatus and process for simultaneously compressing liquids and gases and exchanging the heat of compression with fluids which may be the same liquids and gasses compressed. An apparatus and process for heating maintenance fluids using heat generated when the lift gas is compressed. The compressor may be used for recovering oil and gas from a subterranean formation wherein the production rate is controlled by the gas pressure at the well head, resulting in very slow strokes or pulses and bubbles of lift gas 500 feet long or longer. It may also be used for well maintenance using cooled injection gas from the well and heated fluids, which also may come from the well and be mixed with the well gas during compression, may be conducted without interrupting production.
