[1] Estimation of the three-dimensional (3-D) distribution of hydrologic properties and related uncertainty is a key for improved predictions of hydrologic processes in the subsurface. However it is difficult to gain high-quality and high-density hydrologic information from the subsurface. In this regard a promising strategy is to use highresolution geophysical data (that are relatively sensiti...

SCHLUMBERGER is a large, multinational corporation concerned primarily with the measurement, collection, and interpretation of data. For the past fifty years, most of its activities have been related to hydrocarbon exploration. The efficient location and production of hydrocarbons from an underground formation requires a great deal of knowledge about the formation, ranging in scale from the siz...

Abstract The geomechanical characteristics of a drill formation are uncontrollable factors that crucial to determining the optimal controllable parameters for drilling operation. In present study, data collected in wells drilled Marun oilfield southwestern Iran were used develop adaptive network-based fuzzy inference system (ANFIS) models parameters. specific energy (DSE) was calculated using s...

Abstract Underground CO 2 storage is a promising technology for mitigating climate change. In this vein, the subsurface condition was inherited lot of uncertainties that prevent success project. Therefore, study aims to build 3D model under geological enhancing capacity in Shahejie Formation (Es1), Nv32 block, China. The well logs, seismic data, and data were used construction 3-D petrophysical...

Hydraulic fracturing and matrix stimulation are two major methods of the reservoir stimulation. Hydraulic fracturing, which is the newest technique and technically more complex, is very useful in low permeability reservoirs. Although it has been used widely in hydrocarbon production wells, it is a new method in Iran. In this paper, the effect of sufficient barrier layers on hydraulic fracturing...

Investigation of pore system properties of carbonate reservoirs has an important role in evaluating the reservoir quality and delineating high production intervals. The current study proposes a three-step approach for pore throat size characterization of these reservoirs, by integrating core data, well logs and 3D seismic volume. In this respect, first the pore throats size was calculated using...

Abstract The planning and developmental decisions succeeding the discovery of an unconventional oil gas field is utmost importance in attaining successful exploitation production from these tight reservoirs. development hydrocarbon reservoirs require requires adequate execution which could be challenging, due to sequence heterogeneous lithologies formations. In this study, we designed presented...

Abstract Seismic inversion is a geophysical technique used to estimate subsurface rock properties from seismic reflection data. data has band-limited nature and contains generally 10–80 Hz frequency hence combines well log information along with extract high-resolution acoustic impedance which low as high frequencies. This property qualitative quantitative of that can be analyzed enhance geolog...
