... Polymers have been used in EOR to control the mobility of the injected fluid resulting in better sweep efficiency ( Sorbie, 1991 ). The viscosity of the polymer solution depends on several factors including polymer concentration and brine salinity. Typically, increasing the concentration...

... in the Gulf of Mexico (GOM). The effects of salinity, water cut, and amount of methanol on hydrate formation and plugging risk were studied in this paper. The experimental results and modeling in advanced thermodynamics software showed that an increase in the concentration of methanol and salts...

... (Sheng, 2013a). Carbonates are characterized by heterogeneous formations with low permeability and mixed-to-oil wettability. Moreover, carbonates in the Middle East exhibit harsh conditions of high temperature (>70 °C) and high salinity (>100,000 ppm). Consequently, enhancing oil recovery from...

... Abstract For decades, polymer flooding proved to be one of the most effective enhanced oil recovery (EOR) methods. In addition, low salinity/engineered water injection (LSWI/EWI) has been gaining momentum over the last few years. Both techniques seem to be cheaper than other EOR methods...

... salinity, and heterogeneity with low permeability. The main objective of this study is to experimentally evaluate the performance of a biopolymer (Scleroglucan) in carbonates under harsh conditions of temperature and salinity. This experimental investigation includes polymer rheological studies as well...

.... For using classic anionic surfactants offshore, pretreatment of the water for reducing salinity or the use of alkali are required. In either case an additional unit has to be added to the platform, raising the price of oil production. The structure of the surfactant can be modified for sea water, using...

...Abstract Abstract Performance of anti-agglomerants (AAs) depends on many factors, including salinity, water cut (WC), characteristics of the hydrocarbons, gas composition, reservoir conditions, production system conditions, and especially AA stability at the application conditions. Most AAs...

... of these reservoirs are characterized by having relative high temperature and high salinity, conditions where most available chemicals for EOR have limited applicability. Recent efforts to develop high temperature polymers have been reported, however, there is no clear understanding of what would work best in those...

In order to better understand production and make informed decision about future development plans, it is critical for the operator to accurately characterize fluids in the field through well logging. The challenge in formation evaluation lies in the uncertainty in formation salinity, because the injected...

... Abstract We examined the in-situ hydrate saturations and salinities of gas hydrate-bearing sediments at National Gas Hydrates Project (NGHP) Site 01–10A in the Krishna-Godavari Basin, offshore India, to determine the thermodynamic state of the hydrate system. We determined hydrate saturations...

... the viscosity of the pipeline liquids. The technical choice between KHI and AA is based on the presence of an oil or natural gas condensate phase, the salinity of the produced water, water cut and the possibility of placing a heater on the receiving platerform to aid the dissociation of the hydrates formed.
