Abstract Electrical Submersible Pump (ESP) is one of the major Artificial Lift methods that reliable and effective for pumping high volume fluids from wellbores. However, ESP not recommended applications with gas liquid ratio. The presence free inside pump causes performance degradation which may lead to problems or even failure during operations. Thus, it important investigate effect on under ...

Lapangan MT berlokasi di Tuban, Jawa Timur. Sumur MT-02 merupakan salah satu sumur lapangan yang menggunakan Electrical Submersible Pump (ESP). Dalam pengoperasian pompa ESP sering terjadi permasalahan gas lock. Permasalahan ini ditandai dengan kandungan free tinggi dan ikut terproduksi terakumulasi masuk ke dalam pompa. Apabila cukup banyak pada sumur, maka efisiensi mengalami penurunan menimb...

This paper presents a multiobjective fuzzy genetic algorithm optimization approach to design the submersible induction motor with two objective functions: the full load torque and the manufacturing cost. A multiobjective fuzzy optimization problem is formulated and solved using a genetic algorithm. The optimally designed motor is compared with an industrial motor having the same ratings. The re...

The article is devoted to the investigation of causes failures in centrifugal submersible electric pumping units (CSEP) during work process, measures taken eliminate failures, improve performance and increase time between repairs. In order CSEP, a number changes were made design. Keywords: unit, guidance apparatus, impeller, support ring, friction.
