Functionalization of micromodels with kaolinite for investigation of low salinity oil-recovery processes.
Sandstone formations are ubiquitous in both aquifers and petroleum reservoirs, of which clay is a major constituent. The release of clay particles from pore surfaces as a result of reduced injection fluid salinity can greatly modify the recovery of hydrocarbons from subsurface formations by shifting the wettability properties of the rock. In this paper we demonstrate a microfluidic approach whe...
متن کاملSPE 118830 Efficient Simulation for Low-Salinity Waterflooding in Porous and Fractured Reservoirs
Low-salinity brine injection has emerged as a promising, cost-effective improved oil recovery (IOR) method for waterflooding reservoirs. Laboratory tests and field applications show that low-salinity waterflooding could lead to significant reduction of residual oil saturation. There has been a growing interest with an increasing number of low-salinity waterflooding studies. However, there are f...
متن کاملTitle : “ Evaluation of the Impact of Reservoir Heterogeneity and Mixing on Low Salinity Waterflooding ” Speaker :
The impact of heterogeneity induced mixing between the injected low salinity water and the high salinity connate water is investigated in secondary low salinity waterflooding (LSW). Although LSW has proved to be a promising EOR process in laboratory experiments and field trials, its efficiency can be altered due to mixing with in situ higher salinity connate water. This mixing is caused by mole...
متن کاملSPE 113410 Application of Coalbed Methane Water to Oil Recovery by Low Salinity Waterflooding
Development and production of coalbed methane involves the production of large volumes of water. The salinities and sodium adsorption ratios of coalbed methane (CBM) water from the Powder River Basin range from 370 to 1,940 ppm and 5.6 to 69 respectively. Surface discharge of CBM water can create serious environmental problems; subsurface injection is generally viewed as economically nonviable....
متن کاملLow Power FFT Architectures via Folding Transformation
This paper presents a technique to develop a low power parallel-pipelined architecture for Fast Fourier Transform (FFT). A technique to design FFT architectures via folding transformation and register minimization techniques is proposed. Both complex valued FFT (CFFT) and real valued FFT (RFFT) architectures can be derived using the proposed approach. The proposed architecture for RFFT helps to...
