Heat extraction from deep, hot rocks for energy production is based on water circulation through a man made fracture or natural fractures. As multiple and non-planar fractures in a stress field affect the geothermal reservoir behavior, so the capability to simulate multiple fractures and joints is needed to help reservoir design and operation. A 3D model is developed in this work to simulate an...

We investigated the complexity of reservoir operation and management as a complex adaptive system in this paper. Based on similarities between the process of extracting reservoirs operating rules and the selfadaptive learning behavior of antibody to antigens in the human immune system, a novel reservoir operating rule extraction architecture is proposed. By using the established co-evolution ar...

Recently, global warming problems with rapid population growth and socio-economic development have intensified the demand for water and increased tensions on water supplies. This research evolves the Multi-Objective Coronavirus Optimization Algorithm (MOCVOA) to obtain operational optimum rules of Voshmgir Dam reservoir under the climate change conditions. The climatic variables downscaled and ...

Grieve oil field, discovered in 1954, is located in southeastern Wind River Basin, central Wyoming. This Lower Cretaceous, valley-fill and channelized, Muddy sandstone reservoir is a stratigraphic/structural trap with an average structural dip of 15 degrees. Multiple recovery mechanisms have contributed to produce more than 30 million barrels of premium light sweet crude, including gas expansio...

CO2-based Engineered Geothermal Systems (EGS) have been explored from the perspectives of thermodynamic performance, in-reservoir chemical reactivity, and economic viability. Previous works have correctly noted the important role that initial water content in the geothermal reservoir will play in determining the viability of the concept, but have not examined reservoir water content from a quan...

In this paper, we investigate the collapsing of eight multioperand addition related operations into a single and common (3:2)counter array. We consider for this unit multiplication in integer and fractional representations, the Sum of Absolute Differences (SAD) in unsigned, signed magnitude and two’s complement notation. Furthermore, the unit also incorporates a Multiply-Accumulation unit (MAC)...
