Unconventional/complex reservoirs
This work applies fuzzy logic, a well-established artificial-intelligence technique, to quantitatively assess connectivity between injectors and producers in a giant presalt field in the Santos Basin of Brazil.
Disposal wells remain the lowest-cost solution for produced water, but concerns over seismicity and long-term sustainability are accelerating interest in alternatives.
With a strong presence across US shale in the Bakken, Anadarko Basin, Powder River Basin, and the Permian, Continental Resources is expanding into Argentina’s Vaca Muerta shale as the privately held E&P giant pursues international growth.

The supermajor would be the second to conduct a hydraulic fracturing pilot project in the country. -
The water-shutoff technique is used in some wells of the U reservoir in the Iro field of the Oriente Basin in Ecuador to restore production after an early water breakthrough. This paper compares the production historical data, workovers, and sand-body correlation of wells to understand reservoir behavior, shale-baffle-sealing continuity, the existence of different san…

A pilot project validates the use of an advanced polymerflooding technology on the Alaska North Slope.

This paper outlines an approach to history matching that uses artificial intelligence with an artificial neural network and data-driven analytics. The approach has been used to mitigate history-matching challenges in a mature, highly geologically complex field offshore Malaysia.

A study of a field case concludes that well spacing can be optimized by combing the information extracted from uncertainty and the interpolated maximum net present value.

Oil prices are up and so is the outlook for companies at the heart of the US unconventional oil sector, but they still have their concerns.

The Norwegian oil company is exiting assets in North Dakota and Montana after a decade of development. A Houston-based private equity producer will take over the shale fields.
