the performance of the electric submersible pump (esp) significantly affected by gas void fraction (gvf). thus, using of a rotary gas separator (rgs) is a suitable solution for this issue. the performance of the rgs is function of different parameters such as geometry of impeller, rotating speed, boundary conditions, media viscosity and gvf. in this study, the influences of gvf, viscosity, and ...

Ocean economy plays a crucial role in the strengthening maritime safety industry and in the welfare of human beings. Electric Submersible Pumps (ESP) have been widely used in floating platforms on the sea to provide oil for machines. However, the ESP fault may lead to ocean environment pollution, on the other hand, a timely fault diagnosis of ESP can improve the ocean economy. In order to meet ...

A Moving Horizon Estimator (MHE) is designed for a petroleum production well with an Electric Submersible Pump (ESP) installed for artificial lift. The focus is on estimating the flow rate from the well, the viscosity of the produced fluid, and the productivity index of the well. The software package ACADO is used to implement a Moving Horizon Estimator using a third-order nonlinear model. Simu...

This research discusses the optimization of production carried out in Well A and B. The two Wells are with three layers (multilayer) that have different characteristics for each layer. Based on performance evaluation Wells, it’s known B no longer able to produce naturally (natural flow). Therefore, necessary an artificial lift order be produce.The method used is install electric submersible pum...

Background: Under severe operating conditions, such as lubricant contamination, elevated temperatures and high unit loads, the hydrodynamic (HD) lubrication condition in a HD bearing may degrade and be reduced to mixed and boundary lubrication conditions, which traditional pad bearing materials (Babbitt metal) are not able to sustain. For example, Electrical Submersible Pump (ESP) systems are r...
