Reservoir characterization
Known as Arena, the collaboration aims to improve decision-making across increasingly complex reservoirs and growing volumes of subsurface data.
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.
By integrating experimental and mathematical modeling approaches, this work aims to advance the understanding of sand-detachment dynamics and formation instability under varying saturation conditions.

Analytical tools are useful for reservoir management and can provide simplicity while capturing information derived from events occurring at smaller time scales, which are ordinarily sacrificed in numerical simulations to keep run times reasonable. -
Understanding well and reservoir performance is the ultimate goal of data gathering.
-
The Earth is complex in all directions, and hydrocarbon traps require closure—whether structural or stratigraphic or both—in three dimensions.
-
Applying a cutoff consists of defining a threshold value on one or more logs to separate the reservoir intervals in which hydrocarbons are mobile from the gross rock thickness.
-
This paper presents two real-field case studies from the Norwegian continental shelf that use available DFA data to support the assumptions made from other data on reservoir architecture between wells.
-
A study was required to determine the origin of the tremor, evaluate if it could be followed by other tremors in the future, and estimate its magnitude.
-
A US oil company is using its in-house laboratory's digital imaging devices to analyze reservoir rocks in new plays to answer questions raised by complex tight oil formations that cannot be answered using routine core testing methods.

For decades, the industry has worked to realize the potential of gathering seismic data in wells. But it is a hostile environment for standard equipment. An inventor has developed a fiber optic system that can handle the heat, but he needs backers to see if it can deliver in the ground.

For those in shale exploration, “fracability” is a real word, a critical property, and a point of contention.

This paper describes the application of the iterative ensemble smoother to the history matching of the Norne field in the North Sea.
