Artificial lift
Economical oil extraction depends largely on reducing wear and tear of downhole equipment and tubulars through regular monitoring and batch treatment to cut the risk of corrosion and costly workovers. Having a data-driven approach to scheduling batch treatment can bring down the frequency of treatment and avoid the unnecessary use of resources.
Artificial lift really shines during a downturn. This is because, when capital spending is constrained, artificial lift is one of the few levers an operator has available to increase production while reducing operating expenses.
An artificial-lift concept consisting of an in-well ESP as the primary method and a mudline system as backup has proved effective in an unltradeepwater heavy-oil field.

Natural-gas wells suffer from liquid loading if the gas-flow rate is insufficient to carry liquids to the surface. Because of the technique’s many advantages, plunger lift has been used widely in gas wells for the removal of liquid columns and the rescue of dying gas wells from liquid loading.

This paper presents the results of a 3-year project aimed at mass field implementation of ultrahigh-speed (UHS) electric submersible pump (ESP) systems in western Siberia.

The complete paper explains the steps taken to improve surveillance of beam pumps using dynamometer-card data and machine-learning techniques and reviews lessons learned from executing the operator’s first artificial intelligence project.

This paper identifies potentially significant hidden value of subsea multiphase boosting technology, or aspects of it that have not received adequate attention during the field-development decision-making process.

The motto of the Olympic Games is “Citius, Altius, Fortius,” Latin for “faster, higher, stronger,” which emphasizes the concept of pushing the limits. As an engineer, that approach really speaks to me—and offshore installations, and especially offshore tiebacks, illustrate that concept very well.

Eni conducted a research project to explore the maturity of new technologies to enable economical development of deepwater prospects with tieback distances longer than 50 km and 150 km, respectively, for oil and gas fields.

SponsoredLiquid loading is declining the production rates and limiting the ultimate recovery of shale gas wells. This article explains how subsurface compression can remove liquids from the horizontal and vertical wellbores and increase one operator’s production by 67%.

Hassi Messaoud is a mature oil field with more than 1,100 production wells. Approximately half of the wells are natural flow and the other half use continuous gas lift (CGL) with concentric (CCE) strings.

The first subsea multiphase boosting system was installed in 1994. Since then, it has grown into a technology with a global track record.

Using maglev technology, a new artificial lift system seeks to boost production output by sucking down reservoir pressure from inside the wellbore and from inside the reservoir.
