multiphase flow

This paper describes an “active” monitoring technique that uses a direct search method to optimize the sequence of interval-control-valve (ICV) positions during a routine multirate test in an I-well.

Electrical submersible pump (ESP) systems are critical to achieving the maximum production rates and reservoir pressure drawdown that improve ultimate recovery. But variable volumes of gas in unconventional wells can pose challenges for performance of the ESP.

In trying to reduce the footprint of facilities, operators often select the wrong piping components, hampering the performance. Selection of the right piping can avoid separation issues.

Bypass pigging has advantages over conventional approaches. Its application to multi-phase flow with high wax content crude is discussed.

The SPE Gulf Coast Section’s Projects, Facilities, and Construction study group presented sessions during its spring lecture series on experts’ discussions of the processes involved in metering measurements.

With more than a decade of experience acquired using Venturi/gamma ray multiphase flowmeters (MPFMs), further gains in measurement quality and operational robustness have been achieved.

As environments become more challenging, the importance and complexity of flow assurance has evolved. To effectively manage flow assurance, oil and gas operators must take a holistic approach, particularly when working in deepwater offshore environments.

A relatively small concentration of a defoamer can have a significant impact on the dynamics of multiphase flow within a pipe, but the effect is generally temporary.

In this study, software that is capable of modeling fully transient multiphase flow in wellbore and pipeline has been used to characterize the fluid-hammer effects of well shut-in and startup on the coupled subsurface and surface systems.

The selection criteria for multiphase boosting options remain somewhat subjective. A comprehensive literature review into the working principles of the major pump types identified the intrinsic advantages and limitations of each technology for subsea and downhole applications.
