Reservoir characterization
This work investigates the root cause of strong oil/water emulsion and if sludge formation is occurring within the reservoir using a robust integrated approach.
In this work, a perturbed-chain statistical associating fluid theory equation of state has been developed to characterize heavy-oil-associated systems containing polar components and nonpolar components with respect to phase behavior and physical properties.
The paper describes a parameter inversion of reservoirs based on featured points, using a semi-iterative well-test-curve-matching approach that addresses problems of imbalanced inversion accuracy and efficiency.

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. -
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.

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.
-
In the past decade, there has been a great deal of research and progress in the development of computational methods to assist reservoir engineers in the arduous task of history matching their models.
-
This paper presents an efficient history matching approach that simultaneously integrates 4D repeat seismic surveys with well production data.
-
In this paper, the authors propose a new method for time-lapse-seismic surveys focused on water-injector wells.
