Salt deposits are commonly regarded as ideal hosts for geologic energy reservoirs. Underground cavern construction-induced damage in salt is reduced by self-healing. Thus, studying the influencing factors on such healing processes is important. This research uses ultrasonic technology to monitor the longitudinal wave velocity variations of stress-damaged rock salts during self-recovery experime...

Implementation of waterflooding sometimes cannot increase oil recovery effectively and requires additional methods to recovery. Polymer flooding is a common chemical EOR method that has been implemented in the last few decades provides good effectiveness increasing can reduce amount injection fluid injected into reservoir. Seeing success polymer recovery, it necessary know parameters influence ...

Since the 21st century, under background of steady social and economic development, China’s petroleum enterprises have developed rapidly, but in process oil well engineering, there are also low production, efficiency, order to improve recovery, it is necessary understand implementation effective solutions. This paper analyzes causes production efficiency combination with specific examples furth...

The British Petroleum Deepwater Horizon Oil Spill in the Gulf of Mexico was the biggest oil spill in US history. To assess the impact of the oil spill on the saltmarsh plant community, we examined Advanced Visible Infrared Imaging Spectrometer (AVIRIS) data flown over Barataria Bay, Louisiana in September 2010 and August 2011. Oil contamination was mapped using oil absorption features in pixel ...

A successful cross-linked polymer flooding has been implemented in JD reservoir, an ordinary heavy oil reservoir with high permeability zones. For all that, there are still significant volumes of continuous oil remaining in place, which can not be easily extracted due to stronger vertical heterogeneity. Considering selective plugging feature, polymer enhanced foam (PEF) flooding was taken as fo...

The separation of water from oil that is collected in any oil spill recovery operation is a continuing and necessary requirement during every stage of the effort. Its importance is reflected in the cost of transport and storage of large volumes of oily water, the salvage value of separated oil and the added labor costs associated with long-term recovery operations. This paper addresses the effe...

Water flooding is a commonly used technique to improve oil recovery, although the amount of left in reservoirs after procedure still significant. Gas displacement water an effective way recover residual oil, but occurrence state and flow principles multiphase fluid gas injection are ambiguous. Therefore, process should be studied on pore scale provide basis for formulating reasonable program. M...

a bacterial strain (designated as alcaligenes sp. ms-103) isolated from oil sample of the aghajari oilfield in the south of iran, was able to produce an effective extracellular lipopolysaccharide biosurfactant (1.2±0.05 g/l) on molasses as a sole carbon source. the highest surface tension reduction to level 20 mn/m was achieved by biosurfactant produced by cells grown on molasses under optimum ...

in this research the experimental and theoretical studies on different enhanced oil recovery (eor) techniques, i.e. water flooding (wf), gas injection (gi) and water alternating gas process (wag) were performed on specimens taken from an iranian carbonate offshore reservoir at the reservoir condition. the experimental results for each specified techniques were compared with the corresponding re...
