Abstract: A ball valve assembly includes a ball configured to rotate between an open position and a closed position. The ball valve assembly also includes a cradle having a ball-facing surface. The ball-facing surface faces the ball and is positioned at an end of a fluid passage through the cradle. In addition, the cradle is configured to rotatably support the ball to enable the ball to rotate between the open position and the closed position, and the cradle is configured to block movement of the ball toward the ball-facing surface to establish a separation distance between the ball and the ball-facing surface.

Abstract: A system is described for injecting small controlled amounts of fluid, such as de-emulsifier, into a flowing line at high pressure, in a high-pressure environment such as a subsea environment. The system is connected to the flowing line by tubing lines. It is enclosed either in a high-pressure vessel able to withstand high external pressure or in a vessel that is pressure-matched with the environment. The system is able to inject a controlled volume of fluid into the flowing line at relatively low injection rates.

Abstract: A system, method, and fluid analysis module are provided for the real-time analysis of multiphase fluids. The system generally comprises a sampling system for directing a fluid stream from a flow line to a fluid analysis module, a processor and communicator. The fluid analysis module comprises a sensor for measurement of at least one property of the fluid. The processor processes the measurement data from the sensor, and the communicator communicates the processed data to a central acquisition unit or computer.

Abstract: A technique facilitates fluid flow control with respect to a fluid flowing through a component of a landing string by avoiding or protecting mechanisms otherwise susceptible to debris. A valve is provided in a well component of a landing string and comprises a flexible element. The flexible element is oriented for flexing in an inward direction with respect to an internal flow passage through the landing string. The flexible element enables selective closing off of the internal flow passage without exposing certain types of mechanical mechanisms to fluid flowing through the landing string.

Abstract: The disclosure describes a system to segregate, enrich and capture oil, water and gas samples from a multiphase flow. The system can be used in a subsea location, on the surface or in any other condition where it is connected to a flow of different phases of gas and/or liquid. The samples obtained are representative in composition of the phases flowing at well head conditions in terms of both pressure and temperature. Additionally, a relatively small volume of each phase is used in obtaining the samples. The system connects and disconnects to ports installed at the sampling location nearby the wellhead or the production line. The sampling flow is controlled by means of a pump. The collected samples are separated in mono (or nearly mono)—phase samples (oil, water and gas) and stored in individual bottles.

Abstract: A method for capturing a sample from a wellbore, comprising the steps of introducing a first message and a second message into a tubing positioned within the wellbore. The first message is directed to a first modem connected to a first sampler device to cause the first sampler device to collect a first sample. The second message is directed to a second modem connected to a second sampler device to cause the second sampler device to collect a second sample.

Abstract: A high pressure transfer motor-pump providing for pumping a wide range of process fluids (e.g. chemicals, multiphase fluids, and particle polluted fluids) between intake and outlet ports at high pressure with little to zero leak to the environment and little to no contamination between the pumped process fluid and the driving hydraulic fluid. In accordance to an embodiment a high pressure transfer motor-pump includes a process fluid path extending between an inlet port and an outlet port, a cylinder having a barrier separating a hydraulic fluid path from the process fluid path, a motor coupled across a dynamic seal to a hydraulic pump to manipulate the cylinder barrier by circulating a hydraulic fluid through the hydraulic supply fluid path and a housing pressurized at an inlet pressure of the inlet port and encapsulating the motor, the pump, the dynamic seal and the hydraulic fluid.
