a novel discrete singular convolution (dsc)  formulation  is  presented for the seepage analysis in irregular geometric porous media. the dsc is a new promising numerical approach which has been recently applied to solve several engineering problems. for a medium with regular geometry, realizing of the dsc for the seepage analysis is straight forward. but dsc implementation for a medium with ir...

Declining oil prices has led to a reduction of petroleum exploration as production no longer lucrative area investment in the previous years. Current activities are supported by field work which intensive considering resources required. There is need develop low cost methods delineate areas potential hydrocarbon resources. This research uses Land Satellite (Landsat) 8 Operational Imager (OLI) f...

Submarine groundwater discharge can significantly influence the near shore transport of chemicals into surface waters. Quantification of the sources and rates of such discharge is critical to development of management strategies. Quantification requires a groundwater seepage meter that provides continuous measurements at high resolutions over an extended period of time. An ultrasonic flow meter...

Most of the hydraulic structures are founded on permeable foundation. There is, however, no procedure to fix the basic barrage parameters, which are depth of sheet piles/cutoffs and the length and thickness of floor, in a cost-effective manner. Changes in hydrological and climatic factors may alter the design seepage head of the hydraulic structures. The variation in seepage head affects the do...

Numerous hydrocarbon seep sites at the continental shelf, slope, and in deep water basin are known to feed Black Sea reservoir of dissolved methane. In this study, we identified likely sources gas oil that emitted four located on slope offshore Georgia Eastern 830 1,140 m depth – an area with seepage only (Batumi area) three areas coupled (Iberia Mound, Colkheti Seep, Pechori Mound). The geoche...

The Jurassic Shaximiao Formation in western Sichuan has made significant contributions to the natural gas reserves and production of China, with many fields successively discovered. accumulation evolution progress discrepant gathering law are continuously improved constantly deepened exploration development. In order find evidence for difference method reshape migration their dynamic processes ...
