Reservoir
Canada’s development of large-scale digital drilling core libraries and open geoscience data platforms follows approaches pioneered in Australia, particularly Western Australia, through decades of government investment in geoscience data collection and preservation.
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.

Recent industry activities have turned their focus to the areas of liquid-rich shale (LRS) and light tight oil (LTO) along with unconventional tight and shale gas. -
Unconventional gas is poised to enter its Golden Age and to effect positive global change if it can meet three challenges. Consider the 7 billion people on Earth who use energy each day.
-
Many different completion techniques, such as vertical-well multiseam completions and multiple lateral wellbores drilled into a single coal seam, have been used to develop coalbed methane (CBM) reservoirs.

Looking back through previous editions of this article, I note that, in 2011, I wrote, “there’s a growing tendency in some quarters to use very simple models.” That may be true, but there is also a growing tendency among vendors to offer models with more and more features.
-
Large volumes of gas can be produced at high rates with conventional horizontal- or vertical-well configurations for long periods of time from some methane-hydrate accumulations by means of depressurization-induced dissociation.
-
Exploration wells, unconventional plays, and development wells can benefit from NeoScope, a sourceless formation evaluation-while-drilling solution. Two case studies share how the technology mitigates the risks or logistic complications associated with chemical nuclear sources.
-
As oil companies have moved to more-marginal reservoir targets, application of conventional techniques has often yielded disappointing results, and tighter zones are often abandoned for more-promising target intervals.
-
A successful field trial in which foam was used as a gas-injection conformance enhancer was implemented in the Cusiana field in Colombia.
-
A number of hurdles need to be overcome to reach a successful action/reaction, problem-free status in EOR operations.
-
The Diatomite reservoir in the Belridge field, California, has been under pressure-maintenance water injection to mitigate reservoir compaction and improve oil recovery.
