Estimation of net-to-gross (N/G) on a field wide scale was accomplished by integrating rock property trends and high quality 3D seismic data. Edited and anisotropy-corrected sonic logs from deepwater Gulf of Mexico (GoM) were used in combination with core velocity measurements and Biot-Gassmann modeling to determine shale and oil sand trends in low-frequency Vp-Vs space. These trends equally ap...

A geological model was built for the Sadi reservoir, located at Halfaya oil field. It is regarded as one of most significant oilfields in Iraq. The study includes several steps, essential which importing well logs from six wells to Interactive Petrophysics software conducting interpretation and analysis calculate petrophysical properties such permeability, porosity, shale volume, water saturati...

The exploration well ANH-CR-Montecarlo-1X, in the southern part of Cesar-Ranchería basin Colombia, cuts sedimentary rocks assigned to Cogollo Group (Barremian-Cenomanian). present study integrates petrographic techniques (thin section microscopy and scanning electron microscopy), geochemistry (total organic carbon pyrolysis rock-eval) basic petrophysics establish thermal maturity potential thes...

Considering the global drive toward net-zero carbon emissions in near future, need to find clean sources of energy has never been more important. It is estimated that globally there are tens thousands depleted and abandoned oil fields may be adapted produce green energy. These re-cycled with help air injection, either from production hydrogen, as a direct result oxidation oil, or exploitation i...

We discuss petrophysical analysis of wireline logs, methods for formation evaluation and issues in evaluating tight sandstone formations. The main concerns of log interpretation in tight gas sandstones include porosity interpretation, understanding the effect of clay on the log responses, accurate computation of water saturation, and permeability determination (Kukal et al., 1985). Moreover, va...

Characterizing the top seal integrity of organic-rich caprock shale is critical in hydrocarbon exploration and fluid storage sites assessment because acts as a barrier to low-density upward migrating fluids. This study investigated geomechanical properties Upper Jurassic shales various basins from Norwegian Continental Shelf. Usually, paleo-deposition diagenesis vary basin basin, which influenc...

Conventionally, diagenesis has been studied by making qualitative morphological observations which have organised into complex classification schemes. Petrophysics, with its many quantitative measurements, now gives us the ability to quantify effects of type, degree and timing diagenetic process. The aim this paper is examine how different processes affect petrophysical properties carbonate roc...

Abstract The present study is focused on the subsurface geology of Bannu Basin, a part western Indus foreland Pakistan. For this purpose, some regional seismic profiles and deep exploratory wells data have been used in integration.A total ten mappabale reflection events identifed which are representative specific geological units. In general, based formation trends, horizons dipping northwest d...
