Abstract: A main bore (11) is drilled with an inclined section (17) extending toward a hydrocarbon bearing earth formation (21). First and second laterals (25, 29) are drilled from the inclined section downward into the formation at a steeper angles than the inclined section. The first lateral is opened (29) to the formation at a depth greater than a depth of an opening (31) of the second lateral. After completion, well fluid flows through the openings in the first and second laterals into the inclined section of the main bore. In response to an increasing water content in the well fluid flowing up the main bore, the flow of well fluid from the first lateral is restricted.

Abstract: A magnetic inflow control system (MAG-ICD) for controlling fluid inflow is provided which is based on a variation of conductivity and dielectric constant of fluids as an indicator of a well condition. The MAG-ICD is adapted to vary the flow rate of the fluid flowing in the production string when a water breakthrough is detected in the flow path. This way, if the reservoir recovers and the water content is reduced, the MAG-ICD can recover and allow for flow through the MAG-ICD to increase. If water break through should re-occur, the MAG-ICD will again respond to the increase in water production and choke flow through the MAG-ICD. The MAG-ICD is also adapted to incrementally reduce the flow in a production zone of a well upon detection of water or gas, as opposed to oil.

Abstract: A method for drilling a wellbore includes pumping a drilling fluid from a drilling vessel (102) into a wellbore through a drillstring (142) extending through a marine riser (106) into the wellbore with a surface pump (112). The marine riser (106) extends from the drilling vessel (102) to a subsea blowout preventer (104). The method also includes pumping the drilling fluid from a first annulus (146A) in the riser (106) to a second annulus (146B) in the riser (106) with a subsea pump (126) positioned between the blowout preventer (104) and the drilling vessel (102). The first annulus (146A) is disposed below the second annulus (146B). Further, the method includes adjusting a pump rate of the subsea pump to control the amount of backpressure trapped in the wellbore.

Abstract: A flow control apparatus 110 for a hydrocarbon production system or injection system, the flow control apparatus 110 comprising a choke valve 112 for controlling the flow of production fluid from a well 101 or injection fluid to a well. The flow control apparatus 110 may further comprise a second valve 121 in parallel with the choke valve 112. When the second valve is open the pressure drop over the second valve is less than the pressure drop over the choke valve when the choke valve is open, and the flow control apparatus can be arranged to provide substantially no restriction to the flow of fluid. The apparatus may comprise one or more sensors for finding the differential pressure across the choke valve; and one or more sensors for finding the differential pressure across a portion of the flow control apparatus in which fluid does not flow through the choke valve.

Abstract: Virtual flow estimation is described that is suitable for use under steady-state and non-steady-state (i.e., transient) conditions. Examples of such an approach may not perform discretization of the underlying model described by partial differential equations, but may instead perform discretization in a derived estimator separate and distinct from the underlying model. In this manner, a non-executable continuous time-estimator may be transformed to an executable discrete time-estimator suitable for use in under non-steady state (i.e., transient) conditions.

Abstract: An assembly for the control of the flow of a fluid stream is provided, the assembly comprising a fluid flow conduit having a longitudinal axis; an inlet in the conduit for the fluid stream being processed; an outlet in the conduit for the fluid stream being processed; a control fluid feed assembly having an inlet for a control fluid; wherein the conduit comprises a control portion having one or more apertures therein, the control portion being disposed between the inlet and the outlet of the conduit, the one or more apertures being in flow communication with the inlet for the control fluid in the flow control assembly and extending in a direction at an angle to the longitudinal axis of the fluid flow conduit; whereby in use the control fluid supplied to the inlet of the control fluid assembly is caused to flow into the conduit through the one or more apertures. A method for the control of the flow of a fluid stream comprises causing the fluid stream to flow through a flow control zone from an inlet to an outlet in a first direction; introducing a flow of a control fluid into the flow control zone through one or more apertures at a pressure above the pressure of the fluid stream, whereby the control fluid flows into the fluid control zone at an angle to the first direction to thereby cause a restriction to the flow of the fluid stream through the flow control zone in the first direction.
