... operation. To the authors’ knowledge, a study on the scalability of a commercial reservoir simulator, across two different hardware architectures, has not previously been conducted to this level of detail. The results on realistic models are presented in the hope that they will contribute to the discussion...

... Abstract Reservoir simulation computational costs have been continuously growing due to high-resolution reservoir characterization, increasing model complexity, and uncertainty analysis workflows. Reducing simulation costs by upscaling is often necessary for operational requirements. Fast...

... Abstract Recently, the elevated levels of seismicity activities in Western Canada have been demonstrated to be linked to hydraulic fracturing operations that developed unconventional resources. The underlying triggering mechanisms of hydraulic fracturing-induced seismicity are still uncertain...

... Abstract Automatic differentiation software libraries augment arithmetic operations with their derivatives, thereby relieving the programmer of deriving, implementing, debugging, and maintaining derivative code. With this encapsulation however, the responsibility of code optimization relies...

... Abstract Sour gas injection operation has been implemented in Tengiz since 2008 and will be expanded as part of a future growth project. Due to limited gas handling capacity, producing wells at high GOR has been a challenge, resulting in potential well shutdowns. The objective of this study...

... Abstract Various studies have shown that optimization of SAGD well locations and operating conditions has a great potential to improve the economics of SAGD operations. However, such optimization often ignores geological uncertainties of the reservoir and is based on a single realization. Due...

As a result, mapping dynamic reservoir properties from one grid scale to another one, a process also known as intergrid mapping, becomes a key operation in dealing with composite grid systems. Normally, upscaling and downscaling techniques focus on geological structures and formation...

It is packed with up to 28 primitive machine operations, which are executed in overlapped fashion. Thus, many different operations such as load, store, add, multiply...

... ABSTRACT The problem of multiphase (oil, water, gas), non-iso-thermal fluid flow in a heavy oil reservoir is of great interest in thermal recovery operations, especially steam injection. The much more complex problem of simultaneous stress-strain calculations in the reservoir and adjacent media...
