... Abstract Field results of the developed complex intensification technology with application to carbonate reservoirs are presented in this article. The effect of this technology is obtained by complex treatment of the bottomhole zone (BHZ) with two types of specially selected chemical...

... to their biodegradability, low toxicity, and effectiveness at high temperature and salinity. In this work, we evaluate the potential of a particular biosurfactant for CEOR application in a carbonate reservoir that is characterized by high temperature and high salinity. We evaluate the biosurfactant compatibility...

... Abstract Carbonate reservoirs hold significant reserves of heavy crude oil that can be recovered by non-thermal processes. Chemical, gas, water, and solvent injections are the main methods for carbonate heavy oil recovery. Chemical enhanced oil recovery (EOR) from oil-wet carbonate reservoirs...

... Abstract Factors confronting the application of surfactant flood in high temperature, high salinity carbonate reservoirs include: high concentration of divalent ions in the formation brine, the stability of the surfactant in high thermal environment, surfactant adsorption on carbonate rock...

... Abstract Lab study of chemical EOR for the carbonate reservoir was performed through core characterization, chemical formula screening, surfactant adsorption losses experiments and oil displacement core flooding tests of chemical flooding. The research results lay the foundation of future...

... that the datasets are comparable at every processing step. The processed data shows a good degree of repeatability, and deterministic deconvolution as expected was enough to take care of source wavelet variations between the two surveys. The time lapse VSP and sonic logs were run in carbonate reservoirs where gas...

... Abstract Heavy oil carbonate reservoirs of the giant Wafra field located in the Kuwait - Saudi Arabia Divided Zone hold huge resource of heavy oil in 3 reservoirs, namely 1st Eocene, 2nd Eocene, and Maastrichtian. More than 50 years of primary production from these high porosity, moderate...
