In deep karst reservoirs, the internal environment is complex, and thermal stratification isnot only factor controlling vertical distribution of DIC concentration. Previous studies have not fully understood migration transformation in a deep-water reservoir. this study, reservoir southwest China was chosen, spatial temporal characteristics concentration, pCO2, δ13CDIC value, SIc were investigat...

Two wells close to each other (Well A and Well B) have been selected from the same oilfield in southern Iraq. Both were drilled through Mishrif Reservoir, however, perforated within different sub-units. It was observed that one of shows obvious flow naturally while did not notice any kind flow.
 The type hydrocarbon interpretation by Gas drilling method (GWD), results confirmed both these ...

many large oil and gas fields in the most productive world regions happen to be fractured. the exploration and development of these reservoirs is a true challenge for many operators. these difficulties are due to uncertainties in geological fracture properties such as aperture, length, connectivity and intensity distribution. to successfully address these challenges, it is paramount to improve ...


 The article is devoted to the analysis of geological-petrophysical properties Kursengi and Southern fields Lower Kura depression with a view clarify changes in physical (carbonate content, permeability, porosity) rocks depth. Promising sediments horizons deposits are also considered based on detailed numerous rock samples. Oil gas bearing objects especially distinguished by area, as well...

Since carbonate reservoirs develop pores and fractures have a complex formation pressure system, overflow even blowout seriously threaten the exploration development of these kinds reservoirs. According to characteristics fractured-vuggy reservoirs, field monitoring identification method for has been developed. This is based on top-down logic framework early identification, combined with optimi...
