Hydrogeochemical and Structural Controls on Heterogeneous Gas Hydrate Distribution in the K-g Basin Offshore Se India
Natural gas hydrates occur on most continental margins in organic-rich sediments at water depths >450 m (in polar regions >150 m). Gas hydrate distribution and abundance, however, varies significantly from margin to margin and with tectonic environment. The National Gas Hydrate Program (NGHP) Expedition 01 cored 10 sites in the Krishna-Godawari (K-G) basin, located on the southeastern passive m...
متن کاملelimination of btex , voc vapors from glycol in gas hydrant unit
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
15 صفحه اولGas hydrate stability zone modeling in the Krishna Godavari Basin, Eastern margin of India
The Krishna Godavari (KG) basin is rich in gas hydrate and exhibits an area of wide range of gas hydrate stability zone (GHSZ). In this region, we modeled the base of the gas hydrate stability zone (BGHSZ) utilizing in situ temperature measurements acquired during national gas hydrate program (NGHP) Expedition-01. The bottom simulation reflector (BSR) closely approximates the BGHSZ, and due to ...
متن کاملGas hydrate-related sedimentary pore pressure changes offshore Angola
The thickness of the free gas column below the base of the gas hydrate stability zone is a proxy for the pore pressure in the free gas bearing sediments underneath. In the study area the pore over-pressrues derived under this assumption range between 0 and 1430 kPa ± 30% which appear to be the typical maximum over-pressure that the gas hydrate sediments can withstand before hydro-fracturing occ...
متن کاملA committee machine approach for predicting permeability from well log data: a case study from a heterogeneous carbonate reservoir, Balal oil Field, Persian Gulf
Permeability prediction problem has been examined using several methods such as empirical formulas, regression analysis and intelligent systems especially neural networks and fuzzy logic. This study proposes an improved and novel model for predicting permeability from conventional well log data. The methodology is integration of empirical formulas, multiple regression and neuro-fuzzy in a commi...
