Though the reservoirs are continuous, and the rock properties are generally good, there is likelihood of the existence of baffles, which also have controlling...

... is 200 m. The pore pressure increases are assumed to be 3.0 MPa. In this field, the distance between wastewater injection reservoir and basement rock is 1.5 km. The rock properties are summarized in Table 1 . In this work, it is assumed that the Young's modulus of the basement rock is about 20 times...

... a unique challenge because optimization is not only required in the horizontal direction (well spacing) but also in the vertical (stacking) and diagonal (staggering) directions in order to optimize among the various reservoirs. In addition, variations in reservoir thickness and rock properties between...

... deviation S D = 1 N − 1 × ∑ i = 1 N E i 2 Results and Analysis Permeability and porosity are among the most important rock properties. Of this two, permeability has been found to be a function of porosity as it measures the ease with which fluids flow...

... Abstract This paper presents an innovative method for inclusion of two-phase fault rock properties into upscaled flow simulation models. Faults are generally represented in conventional full-field flow simulation models of clastic reservoirs as 2D planar surfaces. Often, however, faults...

... resonance (NMR) are compared with the "true" rock properties determined directly through core analyses at ambient and/or reservoir conditions. 20 core plugs were studied at both fully and partially saturated states. Results indicate that temperature is a major factor affecting the dielectric, NMR...

Modern history matching strategies pose the characterization process as an optimization problem involving the estimation of rock properties such as porosity and permeability in all grid blocks ( N g ) of a petroleum reservoir...

... well, which can be anywhere in the range of 6–8 million USD. The reasons for these challenges are partially because of the heterogenous rock properties, high stress, and high clay content of the Wolfcamp formation. Prior to introducing the staging and perforating advisor workflow the wells were...

While this goal (an alternative way to "measure" a rock property) is currently the dominant application of Digital Rocks technology in the industry (and, indeed, the emphasis of the current paper), the true power of DNS is that it offers the possibility of understanding...

Abstract Fracture conductivity in shale is largely dependent upon the shale rock properties and the formation conditions...

The creation of a complex fracture network is a function of the stimulation fluid rheology, rock properties and presence...

The geophysical characterization of these sweet spots is highly dependent on the detailed rock properties of the shale, but most often takes the form of some highly optimized seismic attributes obtained after careful seismic processing and a seismic inversion. These seismic attributes...
