A position-indicating tool includes an outer mandrel that accommodates two or more indicator lugs movable between a first position, where the indicator lugs extend past an outer diameter of the outer mandrel, and a second position, where indicator lugs are radially contracted within the outer diameter, an inner mandrel arranged at least partially within the outer mandrel and providing a radial protrusion that radially supports the indicator lugs in the first position, and a pressure block arranged between the outer and inner mandrels to control a flow of hydraulic fluid between an upper hydraulic chamber and a lower hydraulic chamber, wherein, when a pressure threshold is exceeded in the lower hydraulic chamber, the hydraulic fluid is able to flow into the upper hydraulic chamber and thereby allow the outer mandrel to axially translate with respect to the inner mandrel and move the indicator lugs to the second position.

An orbital downhole separator for separating well fluids into constituents of different specific gravities. Specifically, it is designed to separate water from oil or gas. The apparatus comprises a housing with a rotating member therein driven by a motor in the housing. Well fluid flows through the rotating member and is subjected to centrifugal force to separate the components. A flow conditioner is used to facilitate separation. The invention includes several different versions of the flow conditioner including an impeller, a stator and controllers for controlling the speed of the motor in response to signals related to the amount of petroleum in the water.

In one embodiment, the present invention provides an apparatus for creating pulsating fluid flow, including an inlet into which fluid flows and a chamber having an upstream end and a downstream end. The chamber is defined by a pair of outwardly-projecting sidewalls, and the inlet is disposed at the upstream end of the chamber. This particular embodiment further includes at least two feedback passages with opposed entrances at the downstream end of the chamber and opposed exits at the upstream end of the chamber, near where the chamber joins the inlet. At least one feedback outlet leaves each of the feedback passages. A feedback cavity is disposed at the downstream end of the chamber. At least one exit flowline having an exit port leaves the at least one feedback outlet.

Screen assemblies ( ) and a single trip method for selectively fracturing multiple formations ( ) traversed by a wellbore ( ) are disclosed. Each formation ( ) has a screen assembly ( ) having a plurality of valves ( ) positioned adjacent thereto. During the treatment process, the formations ( ) are selectively treated with a treatment fluid that is pumped into the interior of the adjacent screen assembly ( ). The valves ( ) of the respective screen assemblies ( ) progressively allow the treatment fluid to exit from the interior to the exterior of the screen assemblies ( ) such that each formation ( ) is progressively fractured.

A screen assembly ( ) and method for progressively treating an interval ( ) of a wellbore ( ) is disclosed. The screen assembly ( ) comprises a sand control screen ( ) that is positioned within the wellbore ( ) and a plurality of diverter members ( ) that are positioned along the sand control screen ( ). During a treatment process when a treatment fluid is pumped into the interior of the sand control screen ( ), the diverter members ( ) progressively allow the treatment fluid to exit from the interior of the sand control screen ( ) to the exterior of the sand control screen ( ) from a first end ( ) of the interval ( ) to a second end ( ) of the interval ( ) to progressively treat the interval ( ) of the wellbore ( ).

Electrical power generators and methods of producing power in a subterranean well are provided. In a described embodiment, fluid flow through a fluid conduit causes a member to displace or vibrate. The displacement of the member is utilized to induce strain in a piezoelectric material, thereby causing the piezoelectric material to produce electricity. Various means may be used to create turbulence in the fluid flow, thereby increasing displacement of the member, resulting in increased power output from the generator.

An apparatus and method for progressively treating an interval of a wellbore ( ) is disclosed. The apparatus comprises a sand control screen ( ) that is eccentrically positioned within the wellbore ( ) and a fluid delivery tubular ( ) that is disposed within the wellbore ( ) adjacent to the sand control screen ( ). During a treatment process when a treatment fluid is pumped into the fluid delivery tubular ( ), the fluid delivery tubular ( ) progressively allows the treatment fluid to exit from the interior of the fluid delivery tubular ( ) to the exterior of the fluid delivery tubular ( ) from a first end ( ) of the interval ( ) to a second end ( ) of the interval ( ) to progressively treat the interval ( ) of the wellbore ( ).

A method of progressively gravel packing is provided which enables individual sections of a continuous wellbore portion to be gravel packed in succession. In a described embodiment, multiple well screens are positioned in a wellbore. A continuous portion of the wellbore is isolated using, for example, one or more packers, with the well screens being disposed in the isolated portion. The isolated wellbore portion is then progressively gravel packed in successive individual predetermined sections of the isolated wellbore portion.

An apparatus ( ) and method for progressively gravel packing an interval of a wellbore ( ) is disclosed. The apparatus ( ) comprises a sand control screen ( ) that is positioned within the wellbore ( ) and a tubular member ( ) that is disposed within the wellbore ( ) forming a first annulus ( ) with the sand control screen ( ) and a second annulus ( ) with the wellbore ( ). The tubular member ( ) initially prevents fluid communication between the first annulus ( ) and the second annulus ( ). Once the gravel packing operation begins, however, the tubular member ( ) selectively allows fluid communication from the first annulus ( ) to the second annulus ( ) by progressively establishing fluid communication between the first annulus ( ) and the second annulus ( ) from a first end of the interval ( ) to a second end of the interval ( ).

Electrohydraulic actuators and associated methods are utilized to control the operation of downhole well tool assemblies, representatively flow control devices. In a described embodiment thereof, each actuator is positioned downhole and comprises a self-contained, closed circuit hydraulic system including an electrically operable double action primary pump drivingly coupled to an associated well tool assembly via a first hydraulic circuit, and an electrically operable switching pump coupled to the first hydraulic circuit via a second hydraulic circuit interposed therein and operative to selectively alter the control flow of hydraulic fluid to the well tool assembly in a manner reversing its operation. To provide for selective, more rapid control of the well tool assembly, a chargeable accumulator is connected to the hydraulic circuitry and is selectively and drivably communicatable with the well tool assembly.
