In this paper, the compression drive mechanism, which can be considered as most related oil mechanism with reservoir geomechanical properties, has been investigated. The constant total vertical stress on and uniaxial compaction zero lateral strain are two main assumptions in conventional modeling. These not considering arching, leads to a reduction also affects distribution of horizontal stress...

Abstract The city of Matera, as several other ancient historical cities and towns, is recovering a large part its parts developing policy urban regeneration. In the early 90s, during restoration works main square, Piazza Vittorio Veneto, it was re-discovered huge underground space used water reservoir named Palombaro Lungo . It built linking pre-existing smaller caves completed at end nineteent...

We propose a workflow for updating 3D geological meshed models to test different layering scenarios and assess their impact on the simulation of CO2 injection. This operates tetrahedral mesh that encodes rock unit information as well physical properties. The alternative meshes are built by modifying input inserting new horizon defined scalar field. Modifying consistently model while keeping its...

today fingerprinting techniques are increasingly adopted as an alternative and more direct and reliable means of assembling sediment source information. one of the principal assumptions of sediment fingerprinting is that potential catchment sediment sources can be distinguished on the basis of their physical, geochemical and biological properties or fingerprint properties. however, while the so...

Geomechanical studies are very important in the development stages of oil fields to solve many problems such as wellbore instability and sand production. However, this study is not complete without availability mechanical properties rocks. These estimate from petrophysical logs based on compressional shear wave velocities. But often missing most wells, reason might be cost-saving. Therefore, ai...

Introcution: Water-flooding is an effective way to develop the extra-low permeability oil reservoirs and water-flooding induced fracture (WIF) can improve waterflooding efficiency. However, geomechanical properties of rocks may alter due water-rock interactions, which usually increases heterogeneity reservoir affects WIF propagation. Methods: In this study, a method calculate propagation length...

Net pay thickness is defined as that portion of a reservoir which contains economically producible hydrocarbons with today’s technology, prices, and costs. This thickness is a key parameter of the volumetric calculation of in-place hydrocarbons, well test interpretation, and reservoir characterization. A reservoir interval is considered as net pay when it contains hydrocarbons that can flow at ...

Storage of CO2 in deep geological formations has been identified as the most likely near-future option to significantly reduce industrial greenhouse gas emissions in Alberta. In order to assess the risks associated with potential leakage of the injected CO2 the factors influencing the potential loss of containment need to be evaluated. Currently, there is a lack of publicly available, high qual...
