Artificial lift
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.
Three case studies consider the gas-related reasons electrical submersible pumps fail in unconventional shale environments.
Whether it’s reviving inactive gas-condensate wells or identifying overlooked reserves in brownfields, operators are making the most of older wells and fields.

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.
-
To have the flexibility to treat both rich and lean gas wells [up to 100% gas volume fraction (GVF)], a new multiphase pump system has been developed by comparing the different boosting systems performance and analyzing well-by-well production scenarios.
-
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.

Each year at the SPE Artificial Lift Conference and Exhibition, energy professionals convene to connect, grow, and learn—and also to laud outstanding innovators in their field.
