Gas Hydrates, Subsurface Structures and Tectonic Features of the Tuaheni Landslide Complex in the Northern Hikurangi Margin, New Zealand, Revealed by Seismic Attribute Analysis

Autor: Maheswar Ojha, Uma Shankar, Ranjana Ghosh

Publikováno v: Journal of Marine Science and Engineering, Vol 11, Iss 7, p 1359 (2023)

The Tuaheni Landslide Complex, located on the upper slope of the northern Hikurangi Margin in New Zealand, is a unique place to research on slow slip creep-like deformation and seabed failure, as well as their possible relationship with the presence

Capillary pressure equilibrium theory mapping of 4D seismic inversion results to predict saturation in a gas-water system

Autor: Moumita Sengupta, Ranjana Ghosh, Amrita Sen, Saumen Maiti

Publikováno v: GEOPHYSICS. 88:M49-M58

Understanding the effect of fluid concentration in rocks is crucial to characterize a hydrocarbon reservoir. Monitoring of fluid concentration specifically becomes challenging during a sequestration/enhanced oil recovery program because the objective

Pore Characteristics of Gondwana Shale of Eastern India

Autor: Trilok Singh, Kumar Hemant Singh, Piyush Sarkar, Ranjana Ghosh

Publikováno v: Journal of the Geological Society of India. 97:363-374

A complete pore characteristic of the Indian Gondwana shale is studied by combining laboratory experiments and numerical modeling. Mercury injection capillary pressure (MICP), nitrogen gas adsorption (N2GA) and scanning electron microscopy (SEM) are

Assessment of gas hydrate using prestack seismic inversion in the Mahanadi Basin, offshore eastern India

Autor: Maheswar Ojha, Ranjana Ghosh

Publikováno v: Interpretation. 9:SD15-SD26

The Indian National Gas Hydrate Program Expedition-01 in 2006 has discovered gas hydrate in the Mahanadi offshore basin along the eastern Indian margin. However, well-log analysis, pressure core measurements, and infrared anomalies reveal that gas hy

Elastic Anisotropy Modeling of Organic-Rich Lower Gondwana Shale in Eastern India

Autor: Ranjana Ghosh, Piyush Sarkar, Kumar Hemant Singh

Publikováno v: Pure and Applied Geophysics. 178:123-139

Analysis of cores from the Lower Gondwana basin in eastern India confirms the presence of abundant organic matter, indicating a high shale gas prospective zone. Shale is intrinsically (transversely) anisotropic due to the preferential orientation of

Monitoring field scale CO2 injection from time-lapse seismic and well log, integrating with advanced rock physics model at Cranfield EOR site

Autor: Ranjana Ghosh

Publikováno v: Acta Geophysica. 65:1207-1218

Causes and effects of global warming have been highly debated in recent years. Nonetheless, injection and storage of CO2 (CO2 sequestration) in the subsurface is becoming increasingly accepted as a viable tool to reduce the amount of CO2 from the atm
