The development of multilateral wells and long-reach wells has become important to maximizing recovery for many fields. These technologies are often applied in offshore environments, where large reservoir areas are drained from one or more platforms.

This paper describes an “active” monitoring technique that uses a direct search method to optimize the sequence of interval-control-valve (ICV) positions during a routine multirate test in an I-well.

The authors present a geology-driven deep-learning estimated-ultimate-recovery (EUR)-prediction model for multistage hydraulically fractured horizontal wells in tight gas and oil reservoirs.

There remain a number of challenges with CO2 EOR. These include gravity override, poor sweep efficiency, and economic factors.

In chemical-looping combustion (CLC), oxygen is transferred from an air reactor to a fuel reactor by means of a solid oxygen carrier.

The industry is in one of its periodic downturns. Jobs are uncertain or scarce. Profitability is challenged. Bankruptcy looms. Projects are being canceled. Deals are dropped or delayed. It seems there is bad news everywhere. So how do we survive in this environment?

An analysis studied whether a well's toe could be affecting the production performance.

Automated particle-size analyzers are something you will not see on most drilling rigs, but some think this outside-the-oil-field technology will play a big role in the future of the drilling sector.

The future of technology in the global energy industry will be driven by cost pressures, the scope of government regulation, and increased digitization

With the recent drop in oil prices, operators are shifting to optimization of existing assets with minimal costs. For mature floods (water, chemical, and CO2), one low-cost optimization strategy is the intelligent adjustment of well-rate targets.
