摘要： A well control method comprises the steps of drilling a wellbore and predicting a change in flow between the wellbore and a reservoir prior to the change occurring. At least a first and second drilling operation variable are sensed while drilling a wellbore. A predictive device is trained using the first and second sensed variables, to predict the second drilling operation variable at a selected time. The variable predicted may be the rate of fluid flow between a reservoir and the wellbore. The sensed variable may be pressure, a pressure differential, surface temperature, down hole temperature, multiphase flow rate or single phase flow rate, at least one of penetration and bottom hole pressure. The predictive device may utilize a neural network, artificial intelligence, a genetic algorithm, regression analysis, granular computing or an adaptive model. Wherein drilling the wellbore may be in an unbalanced, balanced or over balanced condition.

摘要： Well control systems and associated methods. A well control method includes the steps of drilling a wellbore and predicting a change in flow between the wellbore and a reservoir prior to the change occurring, the predicting step being performed, and the change in flow occurring while drilling. Another well control method includes the steps of: sensing at least one first drilling operation variable while drilling a wellbore, thereby generating first sensed variables; sensing at least one second drilling operation variable while drilling the wellbore, thereby generating second sensed variables; and training a predictive device, using the first and second sensed variables, to predict the second drilling operation variable at a selected time.

摘要： Systems and methods are provided for swellable material activation and monitoring in a subterranean well. A sensor system for use in a subterranean well includes a swellable material, and at least one sensor which is displaced to a wellbore surface in response to swelling of the swellable material. Another sensor system includes a sensor which detects swelling of a swellable material. A swellable well tool system includes a base pipe, a swellable material on an exterior of the base pipe, and eccentric weighting for inducing rotation of the swellable material about a longitudinal axis of the base pipe.

摘要： Systems and methods for thermal recovery of shallow bitumen using increased permeability inclusions. A method of producing hydrocarbons from a subterranean formation includes the steps of: propagating at least one generally planar inclusion outward from a wellbore into the formation; injecting a fluid into the inclusion, thereby heating the hydrocarbons; and during the injecting step, producing the hydrocarbons from the wellbore. A well system includes at least one generally planar inclusion extending outward from a wellbore into a formation; a fluid injected into the inclusion, hydrocarbons being heated as a result of the injected fluid; and a tubular string through which the hydrocarbons are produced, the tubular string extending to a location in the wellbore below the inclusion, and the hydrocarbons being received into the tubular string at that location.

摘要： Phase-controlled well flow control. A well system includes a flow control device which regulates flow of a fluid in the well system, the flow control device being responsive to both pressure and temperature in the well system to regulate flow of the fluid. A flow control device includes a flow regulator for regulating flow of a fluid through the flow control device, and an actuator which is operative to actuate the flow regulator in response to a predetermined relationship between a phase of the fluid and both pressure and temperature exposed to the actuator. A method of controlling a phase change of a fluid in a well system includes the steps of: flowing the fluid through a flow control device in the well system; and adjusting the flow control device in response to both pressure and temperature in the well system.

摘要： Casing deformation and control for inclusion propagation in earth formations. A method of forming at least one inclusion in a subterranean formation includes the steps of : installing a liner within a casing section in a wellbore intersecting the formation; and expanding the liner and the casing section, thereby applying an increased compressive stress to the formation. Another method of forming the inclusion includes the steps of : installing an expansion control device on a casing section, the device including at least one latch member; expanding the casing section radially outward in a wellbore, the expanding step including widening at least one opening in a sidewall of the casing section, and displacing the latch member in one direction; and preventing a narrowing of the opening after the expanding step, the latch member resisting displacement thereof in an opposite direction.

摘要： Casing expansion and formation compression for permeability plane orientation. A method of forming at least one increased permeability plane in a subterranean formation includes the steps of: installing a casing section in a wellbore intersecting the formation; expanding the casing section in the wellbore; and then injecting a fluid into the formation, the injecting step being performed after the expanding step is completed. Another method includes the steps of: applying an increased compressive stress to the formation, the compressive stress being radially directed relative to a wellbore intersecting the formation; and then piercing the formation radially outward from the wellbore, thereby initiating the increased permeability plane. Yet another method includes the steps of: applying a reduced stress to the formation, the reduced stress being directed orthogonal to a wellbore intersecting the formation; and then piercing the formation with at least one penetration extending radially outward from the wellbore, thereby relieving the reduced stress at the penetration.
