Reservoir
This paper documents the testing, integration, and field deployment of a metal expandable packer used as an openhole toe isolation plug in a deepwater well under high-pressure, high-temperature conditions.
Three papers are highlighted as the primary contributions because of their broad industry relevance. They focus on improving formation particle-size characterization, expanding the application of openhole gravel packs in depleted and compartmentalized reservoirs, and advancing the understanding of capillary pressure in sand production.
This paper aims to establish a set of best practices for generating particle-size-distribution data from core samples.

Coalbed methane development can require a large volume of wells, but the costs of logging can be prohibitive, so alternate formation-evaluation solutions are being evaluated. This paper compares state-of-the-art mining logging technology with conventional oil-and-gas approaches. -
Research and development firm Battelle is working on a new induced-seismicity study that aims to help wastewater disposal well operators in Ohio stay on the good side of state regulators.

A new multilayer boundary‑detection service has been introduced to resolve the geological uncertainty associated with horizontal wells in Bohai Bay. Geosteering and real time reservoir characterization were used to reduce the uncertainty.

Saturation-height functions (SHFs) play a key role in reservoir description and in quantifying oil in place. The functions must compare well with other sources of water saturation (Sw), such as core measurements and well-log interpretations. This study reconciles different sources of Sw.

Following years of deliberation, the European Union (EU) released a recommendation on unconventional hydrocarbons and a related communication in 2014. This paper traces the origins and development of these documents, which provide vital clues for the road ahead in European shale-gas regulation.

Computational advances in reservoir simulation have made possible the simulation of thousands of reservoir cases in a practical time frame. This enables exhaustive exploration of subsurface uncertainty and development/depletion options.

With the current changes in the industry, are we seeing the demise of unconventional developments? No, clearly not. The unconventional industry is adapting to deliver the energy demands of the future despite the low oil price.
-
This paper describes how seismic reservoir integration, advanced production analysis, and accurate nanoscale and 3D full-field simulations may address profitability issues and help oil companies to be more efficient in developing unconventional portfolios.
-
This paper presents results from the analysis of the effect of in-fill drilling on parent-well performance, and describes a simplistic approach to understanding the effect of the quest for operational efficiencies and economic cycles on development strategies.

Because the uncertainty analysis is complex and time consuming, in this paper, a stochastic representation of the computer model, called an emulator, was constructed to quantify the reduction in the parameter input space.
