Abstract Analyzing the pore structure in carbonate reservoirs plays a crucial role predicting fluid flow characteristics within these formations. The goal of study was to use machine learning techniques for analysis and estimation permeability reservoirs. We implemented algorithms by examining 2D scanning electron microscope (SEM) images samples from Jaisalmer sub-basin captured at various magnifications. In initial stage analysis, binarization were applied determine sample porosity. Among...

Unconventional reservoirs such as fractured basalts, shale gas and tight sand are currently playing an important role in producing a significant amount of hydrocarbon. The Deccan Trap basaltic rocks form the basement Cambay Basin, India, hold commercially producible In this study two wells drilled through basalts chosen for evaluating lithology, porosity oil saturation reservoir sections. Well logs, gamma ray, high resolution resistivity, litho density, compensated neutron elemental capture...

Low-resistivity pay sands have been identified in four wells, namely: AM-7, AM-8, TA-1 and TA-5, which penetrate the Eocene pay-IV (EP-IV) sand unit of Kalol formation Cambay basin. These wells are located near Dholka Kanwara oilfields The main objective this paper is to evaluate nuclear magnetic resonance (NMR) logs low-resistivity reservoirs from these determine petrophysical properties more accurately than conventional done. thickness varies 5 17 m under study area. has characterized by a...

Abstract Amplitude variation with offset (AVO) analysis is an important tool for identifying natural gas-bearing reservoirs. The changes in seismic amplitudes based on the of density and velocity rock matrix are captured through AVO analysis. current work was performed Ghotaru region Jaisalmer Sub-basin area, where limited discrete hydrocarbon discoveries were observed from Lower Goru Formation during earlier various exploration campaigns. nature reservoir lithofacies developed challenging...

Abstract The Rajasthan basin situates in the western part of India. architecture comprises three significant sub-basins such as Barmer-Sanchor, Bikaner-Nagaur and Jaisalmer. Barmer-Sanchor are intracratonic categories, whereas Jaisalmer sub-basin comes under nature. current study was conducted sub-basin. two regions through a comparative quantitative interpretation with help vintages seismic surveys. Ghotaru Bandha adjacent areas where has seen few hydrocarbon discoveries; however, no...

Abstract Geoscientific evidence shows that various parameters such as compaction, buoyancy effect, hydrocarbon maturation, gas effect and tectonic activities control the pore pressure of sub-surface geology. Spatially controlled geoscientific data in tectonically active areas is significantly useful for robust estimation pre-drill pressure. The reservoir which complex changing frequently circumference motivated us to conduct this study. changes have been captured from fine-scale broad scale...

<title>Abstract</title> Imaging and interpreting seismic signatures in the Goru Formation of Bandha region Jaisalmer Sub-basin is challenging due to its complex geological setting, which features significant lateral velocity variations, dipping flanks, steeply inclined reflectors, overburden strata. This study introduces an innovative polar coordinate velocity-based Reverse Time Migration (RTM) technique with a novel algorithm for reconstructing images intricate structures. A comparative...
