This study focused on the determination of detailed grain morphology using SEM technology on some Athabasca oil sands samples obtained from the Upper McMurray Formation in the Manville Group which occurs in the Western Canada Sedimentary Basin. The research was carried out using scientific techniques to understand grain morphology—being a major effect in discerning reservoir quality—a factor wh...

In this paper, a case study is used to demonstrate a straightforward methodology of faults, fractures and highpermeability layers integration in a single porosity single permeability (SPSP) reservoir simulation model. The application of this method in the Ghawar Arab-D reservoir indicated an adequate modeling of the water encroachment pattern. The described methodology starts with the identific...

Petro physics, rock physics and multi-attribute analysis have been employed in an integrated approach to delineate porosity variation across Tamag Field of Niger Delta Basin. Gamma and resistivity logs were employed to identify sand bodies and correlated across the field. Petro physical analysis was undertaken. Rock physics modelling and multi-attribute analysis were carried out. Two hydrocarbo...

Representativity and accuracy of digital rock physics (DRP) simulations depend strongly on the size image volume resolution obtained. Even with one fastest DRP simulation techniques like pore network modelling, volumes have typically been limited to few cubic millimetres for highly resolved images. In this paper, a super-resolution technique named enhanced generative adversarial (ESRGAN) is use...

For this study we selected 20 drill cores covering a wide range of depths (400-3000 m), from 15 wells, that provide a reasonable coverage of the field. Only andesite, the largely predominant rock type in the field, was included in this sample. We measured bulk density, grain (solids) density, effective porosity and (matrix) permeability on a considerable number of specimens taken from the cores...

The permeability k and porosity φ of vesicular basalts are measured. The relationship between k and φ reflects the formation and emplacement of the basalts and can be related to the crystal and vesicle microstructure obtained by image analysis. Standard theoretical models relating k and φ that work well for granular materials are unsuccessful for vesicular rocks due to the fundamental differenc...

History matching is an inverse problem of partial differential equation on mathematics. We adopt the constrained non-linear optimization to handle this problem, defining the objective function as the weighted square sum of differences between the wells simulation values and the corresponding observation values. We develop an optimization computing program that include Zoutendijk feasible direct...

Breaking down the time limit constraints for conventional compression–permeation (C–P) cell test, this work has, for the first time, experimentally evaluated the cake characteristics of viable wasteactivated sludge subject to polyelectrolyte flocculation and to freeze/thaw treatment under a pressure range of 25–200 kPa. There exists a threshold pressure exceeding which the cake structure would ...
