Artificial lift
By closely monitoring its subsea boosting system, Shell extended maintenance intervals and safely postponed pump replacement at its ultradeepwater Stones field.
The use of real-time wireless downhole pressure gauges proved a valuable alternative to workover operations in two onshore fields in Iraq.
In the wake of the falling number of exploratory wells in the country, Brazil-owned Petrobras addressed audience concerns as well as outlined new avenues for production at the Offshore Technology Conference.

This paper describes an artificial-lift technology, a subsurface compressor system, that simultaneously removes liquids, increases gas production, and improves recoverable reserves in gas wells. -
The way gas injection is used to lift oil and water to the surface needs to change because better control and data may mean more production. At a time when engineers are managing so many wells, they need help from machines.
-
Getting more out of gas lift requires understanding how gas injections interact with the oil, water, and gas flowing up the well—in other words, multiphase flow. Some papers are listed to get you started.

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.
-
A plunger lift optimization software has been developed that enables set-point optimization at scale.
-
A novel PCP configuration was developed from phased design trials and experience in cold heavy-oil production with sand (CHOPS) wells. This configuration uses a modified rotor to create alternating sections of contact and noncontact within a conventional stator.
-
With the acquisition of Schlumberger’s rod lift business, Lufkin gains several products, brands, and key proprietary software.

Wellbore tortuosity is a term that has steadily increased in relevance to the oil and gas industry over the past decade, but its importance is especially clear in the current environment.
