... out two core flooding tests assembled in series at 8100 psi of injection pressure and 65°C. It was performed two different injection flow rates (1 mL/min and 0.1 mL/min) of 16 times diluted synthetic seawater. It was possible to observe three different porosity behaviors along the sample length...

...% weight of naphthenic acid were used as the saturation fluids. The cores were aged at 110 °C for 20 days to alter the initial water-wet condition. Two sets of tests were performed in the HSC to study the effects of the reduction of Na + and Cl - ions in seawater composition. Additional oil recovery...

... Abstract This paper presents the results obtained from decommissioning an offshore production loop (7.625 in., 19 km) by flushing with inhibited seawater and compares flow-assurance software simulations to data collected in the field. After completion of the subsea production system shutdown...

... Abstract A technical-economic research was done evaluating microfiltration polymeric membranes and cartridge filters as pretreatment of Sulfate Removal Units (SRU). These units were installed in a Stationary Production Unit (SPU) to reduce the concentration of sulfate from seawater (injection...

... Abstract The work addresses technical issues of waterflooding operations in offshore environments from the standpoint of fluid-fluid and rock-fluid interactions. Seawater is the preferred source of injection fluid for waterflooding in offshore reservoirs. Given the elevated CAPital EXpenditure...

... Abstract New local subsea processing systems will need to be developed to allow remotely located satellite oil fields to be produced economically. One such system treats seawater for injection into the reservoir. As reservoir waters often contain elevated concentrations of barium or calcium...

There is free flow of seawater into the base of the protection structure and hence no needs to design against the water pressure. The top...

However, the team recognized the risk of injectivity loss due to improper seawater filtration and chemical treatment. Required filtration level was estimated...
