Abstract Oil and gas recovery may cause formation damage during drilling, completion, production phases. As a result of fundamental chemical, thermal, mechanical, biological interactions, can occur due to impairment permeability porosity, causing undesirable operational economic problem. The fluid-rock interactions resulting from oilfield chemicals injection enhanced oil (EOR) such as chemical ...

In order to accurately predict geomechanical parameters of oil-bearing reservoirs and influencing factors volumetric fracturing, a new method parameter prediction combining seismic inversion, well logging interpretation production data is proposed in this paper. Herein, we present structure model, petrophysical model model. Moreover, three-dimensional typical reservoir was established corrected...

The appropriate design of the operating pressure underground gas storages (UGSs) is great significance to their safe and profitable operation. In situ stress basic data for determining upper limit UGSs, analyzing fault stability in reservoir areas, evaluating trap tightness. Generally, injection UGSs a comprehensive geomechanical problem. After research comparison measurement methods, it believ...

Abstract One of the most important oil and gas drilling studies is wellbore stability analysis. The purpose this research to investigate from a different perspective. To begin, vertical stress pore pressure were calculated. lowest maximum horizontal calculated using poroelastic equations. strike-slip normal fault regime was shown by in situ values. 1-D geomechanical model utilized failure mecha...

reservoir characterization plays an important role in different parts of an industrial project. the results from a reservoir characterization study give insight into rock and fluid properties which can optimize the choice of drilling locations and reduce risk and uncertainty. delineating hydrocarbon bearing zones within a reservoir is the main objective of any seismic reservoir characterization...

The influence of physico-chemical properties of Oyun Reservoir, Offa, Nigeria (a shallow tropical African reservoir) on its zooplankton composition and abundance were investigated at three stations for two years between January 2002 and December 2003. Diversity is not high: only three groups of zooplankton were found: Rotifera with eight genera; and Cladocera and Copepoda with three genera each...
