Stimulated reservoir volume (SRV) fracturing in tight oil reservoirs often induces complex fracture-network growth, which has a fundamentally different formation mechanism from traditional planar bi-winged fracturing. To reveal the mechanism of fracture network propagation, this paper employs a modified displacement discontinuity method (DDM), mechanical mechanism analysis and initiation and pr...

Geothermal and unconventional hydrocarbon reservoirs are often characterized by low permeability and porosity. So, they are difficult to produce and require stimulation techniques, such as thermal shear deactivation and hydraulic fracturing. Fractures provide porosity for fluid storage and permeability for fluid movement and play an important role in production from this kind of reservoirs. Hen...

This paper describes a new modeling framework for microscopic to reservoir-scale simulations of hydraulic fracturing and production. The approach builds upon fusion two existing high-performance simulators behavior: the GEOS code hydromechanical evolution during stimulation TOUGH+ multi-phase flow are informed by experimental studies at laboratory scale incorporate important micro-scale mechani...

Hydrocarbon production from unconventional resources and the use of reservoir stimulation techniques, such as hydraulic fracturing, has grown explosively over the last decade. However, concerns have arisen that reservoir stimulation creates significant environmental threats through the creation of permeable pathways connecting the stimulated reservoir with shallower freshwater aquifers, thus re...

The stress-strain relationship in shales is generally time-dependent. This concerns their long-term deformation unconventional reservoirs, and its influence on the situ stress state therein. paper presents an experimental investigation time-dependent of Longmaxi shale gas shale. A series creep experiments subject samples to long-term, multi-step triaxial compression. It found that exhibit varyi...

As oil and gas production from conventional reservoirs is declining and oil price is going up, unconventional mudstone reservoirs (“shale-gas”) are becoming more important. However, while their characterization is of utmost importance for production planning, these low permeability rocks are very challenging to characterize due to their complex nano-scale pores and mineral structure. 3D imaging...

Executive Summary The objective of Reservoir Monitoring Consortium (RMC) is to develop new methods for dynamic reservoir monitoring. We will carry out a number of focused applied research projects in reservoir monitoring that are directly pertinent to the current and future needs of our industry sponsors. We will develop specific workflows for different types of reservoirs. This will include th...

Large-scale data policies easily may have unplanned effects of ‘’homogeneity” on the available data supply. A narrowing of the scope of the data supply tailored to established research paradigms could limit the opportunities for unconventional, but also adventurous, new research directions with the risk of slowing down scientific progress. A systematic assessment of data portfolios not only on ...

In this paper, we propose the use of Alpha-Beta associative approach as an Unconventional Computing method in the pre-diagnosis of malignant tumors of breast cancer, obtaining an accurate result in a simple way; trying to avoid invasive diagnostic methods like biopsies, as far as possible. This proposal provides for the Alpha-Beta Support Vector Associative Machine created in 2008 and tested fo...
