... Abstract This paper shows the comparison obtained in the oil and gas production increase by cyclic gas injection produced at Provincia field and the cyclic solvent + gas injection (same field). According the composition of the production gas of Provincia Field ( Table 1 ) used during the cyclic...

... Abstract There has been a large number of laboratory tests run in the past, looking at recovery of heavy oil by chemical flooding (polymer, surfactant and SP or ASP systems). These tests have all shown a potential for significant incremental oil recovery from chemical injection compared...

... Abstract Solvent injection has been given attention to enhance oil recovery by sole use or in combination with a thermal method to develop light, medium, and heavy-oil fields. To make this process efficient, retrieval of expensive solvent efficiently is required. This can be achieved...

... of the diluent). This study provides guidelines to select one of the three following methods: diluent injection, emulsion injection or reservoir-based technology. Previous operators performed extensive reservoir characterization and simulation modeling which led to recovering over 200 million barrels of heavy...

... Abstract Foam has been used to improve the efficiency of steam injection since the late 1970s and the process has been applied successfully in several fields in particular in California but interest sagged at the end of the 1990s due to low oil prices and little activity took place for several...

... Properties A compact ion chromatograph was employed to obtain the ionic concentrations of the effluents after the water injection experiments. Even though, it was not possible to detect bicarbonate concentrations using ion chromatography analysis, the effluent samples were treated with methyl orange...

... Abstract Steam injection is a known Enhanced Oil Recovery technique with application in heavy oil exploitation. The process is generating a rather high amount of carbon dioxide (CO 2 ) that according to the current climate regulatory initiatives should be reduced. CO 2 injection to enhance...

... Abstract The purpose of this research work is to show laboratory experiments conducted at 1500 psi and 350°C, experimentally simulating a reservoir located in the Gulf of Mexico. The experiments conducted used a novel process that involved a hot fluid to be injected with an ultra-dispersed nano...

... Abstract This paper shows the evolution of the cyclic steam stimulation (CSS) process in a Colombian heavy oil field. Some challenges have been faced like: low injectivity in the first stimulation cycles, presence of swelling clays, low lateral and vertical continuity of the producing sands...

... coning and uneven reservoir drainage that leaves valuable bypassed oil in the ground. To compound the issue, the rapid production increase of highly mobile fluids such as water or gas generates high operational costs for fluid treatment, re-injection, and disposal. Previous publications have explained...

... oil viscosity require an enhance oil recovery (EOR) processes to pursuit a commercial development. Among the recovery methods applied to heavy oil reservoirs, the most popular is steam injection in its different schemes. Nevertheless, in high initial water saturation environments the thermal...

... Abstract Steam injection is one of most successful techniques for improving oil recovery in heavy oil fields. However some reservoirs have characteristics that are not adequate for the implementation of this technique due to reservoir heterogeneity, where steam driving is present in most...

... recovery factor, the foam injection can be mentioned. The foam may be used as a selective block agent of the reservoir, which reduces the effective permeability zones already swept with high permeability. A widely used tool for this purpose is the simulation of petroleum reservoirs, which through...

... Abstract Staatsolie conducted several screening studies in the past decade to explore the potential of enhanced oil recovery (EOR) for its heavy oil fields in Suriname. The latest screening study was performed in 2011. It indicated that combined gas and water injection could be a highly...

...Conclusions A testing site for CO 2 injection has been identified in this heavy oil fractured reservoir complex where the geological structure and faulting system create a relatively confined reservoir volume with limited communication with the main reservoirs. A finely-gridded sector...
