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 presents how a US onshore operator took a three-step approach to optimize more than 100 rod-pump wells. The approach involved data consolidation, automated work flows, and interactive data visualization. -
Subsea pumps are used for gas/liquid separation, subsea compression, and subsea boosting. Solutions aiming at cost reductions are crucial to make subsea processing projects feasible. A cost- and complexity-reduction solution for the subsea electrical power supply is a critical consideration.
-
Extensive analysis has led to the conclusion that downhole gas compression provides a greater increase in gas production than wellhead gas compression because of the additional drawdown created.

Rockwell Automation’s Luis Gamboa explains his company’s new solution designed to allow operators to collect, sort, and reconcile the quality and quantity of data from multiple sources to optimize field data.

Two things stood out when I looked at this year’s abstracts. First, well over half of the abstracts were related to electrical submersible pumps (ESPs). This is a significant increase from the last couple of years. Second, there was a clutch of artificial-lift-method-selection papers.
-
This paper focuses on a fit-for-purpose methodology to evaluate well-production performance for a wide range of artificial-lift techniques.
-
This paper presents an artificial-lift selection process to maximize the value of unconventional oil and gas assets.
-
This study presents a methodology to define the most-adequate artificial-lift technique on the basis of technical limitations, a suitability coefficient (based on an attributes table), and economic analysis toward horizontal well configuration.

With Over 200 Shale Well Installs, This Slug-Smoothing Lift Technology Is Boosted By Schlumberger JVSlug flow has made the life of an unconventional production engineer a bit complicated, but a new downhole technology may smooth things right out by solving some big artificial lift problems for the shale sector.
-
Unconventional production patterns in the Permian Basin are leading producers to replace electrical submersible pumps (ESPs) with gas lift, which had been little used there.
