Electric Submersible Pumps

The electric submersible pump (ESP), sometimes called “submergible, ” is perhaps the most versatile of the major  oil-production artificial lift methods. Technical Data used in the field explained in petroleum courses in Rawalpindi.  This chapter provides the reader with a broad understanding of the key factors in selection, installation, and operation of electric submersible pumps. ESP topics covered include the ESP system; applications; ESP system components, selection data and methods; handling, installation, and operation; and troubleshooting.

The ESP system comprises a downhome pump, electric power cable, and surface controls. In a typical application, the downhome pump is suspended on a tubing string hung on the wellhead and is submerged in the well fluid. Some more details of petroleum courses in rawalpindi are as under.

The pump is close-coupled to a submersible electric motor that receives power through the power cable and surface controls.

The ESP has the broadest producing range of any artificial lift method. The standard 60-Hz producing range of the ESP extends from a low of 100 B/D of total fluid up to 90,000 B/D. Variable-speed drives can extend the producing range beyond these rates. Although most operators tend to associate ESP’s with “high volume” lift rates, the average ESP produces less than 1,000 B/D of total fluid in continuous operation.

ESP’s are used to produce a variety of fluids and the gas, chemicals, and contaminants commonly found in these fluids. Currently ESP’s are operated economically in virtually every known oil field environment. The WOR is, in general, not significant in assessing an application. TSK Training for Skills and Knowledge is the best institute in Rawalpindi Islamabad for Pakistani Students who wants to join oil field after petroleum courses in Islamabad.
