This paper reviews the IOR/EOR technologies currently being applied to unconventional oil reservoirs.

While sand control in production wells catches much attention, water-injection wells also are subject to sand-control problems triggered by water hammer, cross flow, and backflow. Newly developed screens for water-injection wells have been demonstrated with promising results.

The authors present a novel data-driven tool for fast fracture identification in post-stack seismic data sets.

Seismic imaging provides vital tools for the exploration of potential hydrocarbon reserves and subsequent production-planning activities. The acquisition of high-resolution, regularly sampled seismic data may be hindered by physical or financial constraints.

This paper details the design and execution of what the authors say they believe is the first successful frac-pack operation in a previously gravel-packed well.

This paper discusses a probabilistic flux and erosion model and work flow that extend the ability to estimate inflow through sand screens on a foot-by-foot basis along the wellbore using the well's completion details, production rate, and reservoir and bottomhole flowing pressures.

In 2014, a research and development (R&D) project was initiated to increase the life expectancy of Gulf of Mexico (GOM) Miocene and Lower Tertiary water-injection (WI) wells, several of which had suffered a severe loss of injectivity within only a few years of completion.

The $600-million deal sees NGL net around 580,000 B/D in disposal capacity and 680,000 B/D in transportation capacity via 19 saltwater disposal wells and a network of produced water pipelines. Hillstone also holds an aggregate of more than 110,000 acres in the Delaware Basin.

With its $4.5-billion acquisition of ExxonMobil’s remaining portfolio on the Norwegian Continental Shelf now official, Var Energi says it hopes to realize its ambitious growth plans.

Output fell below 12 million B/D and was down more than 300,000 B/D from an all-time high in April, according to data from the US Energy Information Administration.
