...ESP Design in an AICV Completed Well An oil well was selected as a candidate for an ESP-AICV integrated completion. The well is located in a fractured carbonate reservoir and was planned to be drilled in a horizontal section. Water was expected to encroach causing the oil rate to decline...

... Abstract The novel dual electric submersible pump (ESP) completion was designed to maximize oil recovery by improving waterflooding efficiencies while minimizing capital expenditures (capex) and surface facilities. The design enables the operator to produce oil and formation water from the same...

... Abstract The objective of this paper is to demonstrate the problematic of asphaltene deposition during oil production via ESPs in Mittelplate oilfield. Furthermore, different measures implemented for prevention and removal of asphaltene precipitations are presented and summarized. Production...

... field in ONGC are facing an acute problem of decrease in pump efficiency and ultimate failure of Electrical Submersible Pumps due to deposition of inorganic scale. The methodology for carrying out the study consists of a detailed Compositional Analysis of a sample of scale retrieved from inside the ESP...

... and water flowrates in source water wells, extended-life ESP to enable production across a wide production range to cover the response of the waterflooding, increasing solids production, heavy oil, and installations of ESP in deep and tortuous wells. This technical and strategic approach covers artificial...

...Oscillations and Instabilities, what is the right term to use? Abstract Electrical submersible pumps (ESP) oil well production often requires handling large amounts of free gas, leading to numerous ESP trips, which limits drawdown. To maximize production and eliminate downtime, a technique...

... Abstract The Electrical Submersible Pump (ESP) has become one of the most popular ALS worldwide due to its capacity of lifting high fluid volumes with high efficiency, however, its application is questioned under some circumstances related to difficulties that this system presents when managing...

... The inorganic scales that were detected during several workover jobs after pulling out the ESP of the well were later identified as calcium carbonate, located in the tubing section near the ESP motor, and calcium sulfate scale, located in the motor section, shown in Figure 1 . The use...

... Abstract As the second most widely used artificial lift method in petroleum industry, ESPs help maintain or increase flow rates by converting kinetic energy to hydraulic pressure. During the entire life of an oilfield, water is invariably produced with crude oil. As the field ages, the water...

... and temperatures, absolute and relative tubular movement play a significant role in completion integrity and longevity. Collaboration with one of KOC’s major Electrical Submersible Pump (ESP) service partners yielded a unique dual concentric design that facilitates ease in completion deployment and equal ease...

... It is most profitable to reach this transition point with as few ESPs as possible. The first ESP install can be capitalized which reduces its financial burden however subsequent replacement ESPs cannot. Which is why operators need to increase the run life of their ESPs and increase the mean time...

... oil by 2 orders of magnitude (from 1000 cP to 10cP) for extending Electric Sumersible Pump (ESP) run life, this paper is exclusively focused on motor preheating results. The motor is energized with low voltage at a frequency of 120Hz maintaining the voltage low enough in order to keep the supplied...

... Abstract As an artificial lift method for high-flow-rate oil production, electrical submersible pumps’ (ESP) performance surfers from gas entrainment, a frequently encountered phenomenon in ESPs. When it occurs, ESPs can experience moderate or severe head degradation accompanied with production...

...-ranging impact for mature fields around the world. The study uses a sample of 10 wells initially completed with electrical submersible pumps (ESPs) with different production characteristics and well profiles from a mature field in South America. Reactivating abandoned wells is particularly challenging...

... Abstract Electrical submersible pump (ESP) technology has evolved to become a critical component in many production operations and well productivity enhancement. However, one of the important challenges in real-time ESP-enabled well management is the implementation of intelligent systems...

..., but with some operational limits. This completion used a conventional ESP with Y-tool to create a counteractive pressure drawdown just below the Oil/Water contact in an effort to limit the progression of the water cone. The major limitations with this ESP configuration were casing size (can only be used in 9...

... perforations and sucker rod pump (SRP) unit changes. The artificial lift systems of more than one third of the producers were converted to electrical submersible pumps (ESPs). Three new high-rate horizontal producers were also drilled. To maintain reservoir pressure, nearly all the produced water had to be re...
