Unconventional/complex reservoirs
This case study presents a procedure in which the operator compared production from wells with adjusted wettability to a control group, finding that the adjustments resulted in significant improvements in production and reductions in produced water.
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.

With multistage operations becoming the industry norm, operators need easily deployable diversion technologies that will protect previously stimulated perforations and enable addition of new ones. This paper reviews several aspects of the use of in-stage diversion. -
There is increasing interest in drilling the Austin Chalk formation, with hopes that the latest unconventional development methods can deliver a boom in a play that has seen several over a 90-year history.
-
SPE conferences in Calgary examine the challenges of finding and producing heavy oil and unconventional hydrocarbons at a time when Canadian producers are feeling exceptional price pressures.
-
With an uncertain future spawning from the Brexit referendum, the British government is seeking to maintain as much consistency in its energy policy as possible.
-
A new play in the Permian Basin is unconventional in an unexpected way: there is a small group of independents producing from a watery formation where oil production begins after they have pumped only water for weeks.
-
Carbo Ceramics is making big strides in the use of ceramic proppant.
-
Saudi Aramco has begun moving toward the production phase of its ambitious plan to develop its enormous hoard of unconventional gas resources.
-
Understanding petrophysical properties well enough to make drilling decisions, particularly for tight gas can be a challenge. A new computer system aims to help analyze the extensive data involved.

This paper offers an alternative explanation for the early boundary-dominated flow related to dissolution of salt-sealed natural fractures in the shale.

On the basis of production data, diagnostic methods, and field observations, it is becoming increasingly clear that induced unpropped fractures created during the hydraulic-fracturing operation play a critical role in determining the success of fracture treatments.
