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.

One of the biggest ways to lower the cost of production from shale would be to identify zones that are productive, or not, before fracturing them. -
The importance of reducing emissions of methane, a short-lasting but powerful atmospheric greenhouse gas (GHG), received close attention from panelists at an IHS CERAWeek strategic dialogue, Tightening the Valves on Global Methane Emissions.
-
When it comes to hydraulic fracturing, steadiness may not be a virtue. That was the conclusion of a test to see if rapid pump rate variations would lead to greater production than conventionally fractured stages when the pressure was held steady.
-
With the world’s fifth-largest estimated shale gas reserves, there is great potential for Saudi Arabia to replicate North America’s unconventional growth.
-
A strategic objective of Saudi Aramco is exploring and developing deep and unconventional gas reservoirs, many of which are considered extremely tight.
-
On the far end of the flowback spectrum is a completion process called soakback. If the well has to be shut in until takeaway capacity is available, the completion fluids soak into the shale rock. Flowback analysis can help understand what happens in the formation.
-
Researchers at Yale University who analyzed groundwater wells in the Marcellus Shale area have determined that hydraulic fracturing is highly unlikely to be a direct source of contamination.
-
While the collapse in oil price is reshaping opinions about the North American shale revolution and the outlook for oil producers, natural gas producers in the United States are in a somewhat different position
-
Shale-gas resources were explored in Saudi Arabia by adopting a “technology-driven” approach against the US-based approach that might be termed the “factory” or “statistical” approach.
-
Although refracturing is a topic that has gained a lot of interest, many shale producers have been sitting on the sidelines because early results did not justify the spending
