As the most common stimulation treatment in carbonate reservoirs, acid fracturing is also frequently used geothermal wells, but it has not been applied deep thermal reservoirs. The application of a multi-stage technology Xiong’an reservoir introduced this paper. field achieved good effect. Multistage can effectively communicate aquifer reservoir, improve length corrosion fracture, increase cond...

In thin-layered reservoirs, drilling engineers face tough challenges—planning their drilling programs to follow the most productive reservoir layers while avoiding nearby water, gas or high-pressure zones. The rewards for a successful drilling strategy are clear—increased oil production and reduced water cut. In an oil field in the Persian Gulf, for example, oil production was increased four- t...

Reservoir sediments from Lake Roosevelt (WA, USA) that were contaminated with smelter waste discharged into the Columbia River (BC, Canada) were examined using three measures of elemental release reflecting varying degrees of physical mixing and time scales. Aqueous concentrations of Cd, Cu, Pb, and Zn in the interstitial water of reservoir sediments, in the gently stirred overlying waters of i...

A reservoir model of a Recent steady-state sedimentary system in which the reduced sulfur and oxidized sulfur reservoirs were coupled with the oxidized carbon and reduced carbon reservoirs was constructed. The time curve of the sulfur isotope ratios of the sedimentary sulfate reservoir was used to drive the model back to the beginning of Cambrian time (600 million years ago), producing the rese...

Carbonate reservoirs are usually difficult to map and identify in seismic sections due their complex structure diagenetic material with high heterogeneity. The East Java Basin is a perfect example of these carbonate structures excellent hydrocarbon accumulation. In order obtain better characterization the reservoir this basin, acoustic impedance inversion performed here. Acoustic product P wave...
