Unconventional/complex reservoirs
This year’s selected papers showcase meaningful advances across condensate‑rich tight gas, tight sandstones, and coalbed methane reservoirs, each contributing new tools for improving predictability and field-development efficiency.
This paper presents a novel approach to predict reservoir porosity by conditioning seismic data, calibrating seismic impedance inversion, and tailoring rock-physics analysis.
This paper presents findings reinforcing the argument that acid fracturing is a strong alternative stimulation method to improve productivity in the Austin Chalk formation.

Approximately 5% of world annual gas production is being flared or vented. This is equivalent to approximately 110–140 billion m3 (Bcm) of gas, and equates to the combined gas consumption of Central and South America in 2013. -
For the past 2 decades, the use of DNA sequencing technology has largely been relegated to the domains of criminal forensics and the healthcare industry. One company is betting that the shale industry soon will join that list.

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.
-
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.
-
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.
-
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
-
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
