Cap rocks are dams which can prevent the upward movement of hydrocarbons. They have disparities and weaknesses including discontinuities, crushed areas, and faults. Gas injection is an effective mechanism for oil recovery and pore pressure. With increasing pore pressure, normal stress is reduced, and the integrity of impermeable boundaries (cap rock, fault, etc.) becomes instable. A successful ...

vartun geothermal region (vgr) is located in west central part of iran, 300 km in the southeast of tehran. vgr area is 277 km2and there are some geothermal surface manifestations such as warm springs and travertine deposits. there are three warm springs which their temperature varies from 35.3 to 43.1 °c. their ph is a little bit acidic and is about 6.1-6.2. based on geothermometery studies var...

Ž . Field experiments show ground penetrating radar GPR can be used to image shallow carbonate stratigraphy effectively in a variety of settings. In south Florida, the position and structure of cap rock cover on limestone can be an important Ž . control on surface water flow and vegetation, but larger scale outcrops tens of meters of cap rock are sparse. GPR mapping through south Florida prairi...

Following the last glacial maximum (LGM), the demise of continental ice sheets induced crustal rebound in tectonically stable regions of North America and Scandinavia that is still ongoing. Unlike the ice sheets, the Alpine ice cap developed in an orogen where the measured uplift is potentially attributed to tectonic shortening, lithospheric delamination and unloading due to deglaciation and er...

in this paper, fourteen mt stations along a profile perpendicular to the main geological structure were used in order to identify the geology of sabalan geothermal field including the extension of the surface cap-rock and clay-cap layers. the mt data collected between 1-8192 hz is of useful quality and provides good control on the surface layers in many areas. it means that reliable modeling sh...

Two separate and distinct diamictite-rich units occur in the mixed carbonate-siliciclastic PolarisbreenGroup, which comprises the top kilometer of47 km of Neoproterozoic strata in the northeast of the Svalbard archipelago.The platformal succession accumulated on the windward, tropical to subtropical margin of Laurentia.The older PetrovbreenMember is a thin glacimarine diamictite that lacks a ca...
