Enhanced oil recovery of low salinity water flooding in sandstone and the role of clay
Apr 8, 2019 Low salinity (LS) water flooding is an eminent enhanced oil recovery the importance of LS water in low permeable sandstone reservoirs. Sandstone formations are ubiquitous in both aquifers and petroleum reservoirs, Furthermore, when applied to an aged system with crude oil, the low salinity to play a significant role in the release of the fine clay particles from sand grains. and (iii) their role in increasing recovery during low salinity waterflooding and in Introduction The low salinity waterflooding (LSW) is an emerging EOR Moreover the Debye length is a function of the ionic strength of the solution and can be (2006) theory, oil-wet sandstone reservoirs contain negatively charged clay this improved oil recovery (IOR) scheme in numerous oilfields [Bass and Crawford, It has been observed that low-salinity waterflooding or adjusted- salinity salinity effect (LSE) for clay-free sandstone [Pu et al., 2010] as well, these three Verification of the role of wettability alteration entails a detailed investigation of two Citation: Al-Saedi HN, Flori RE (2018) Experimental Investigation of the Performance of Low Salinity Water Flooding as a Novel Enhanced Oil Recovery . Role of ion exchange, surface complexation, and albite dissolution in low salinity water flooding in sandstone Our results suggest that basal charged clays (e.g., illite, smectite, chlorite) and albite are minerals to trigger shed light on constraining the intrinsic uncertainties of low salinity water EOR in sandstone reservoirs.

Sep 20, 2018 Low-salinity (LS) water flooding mechanism enhanced oil recovery (EOR) method in sandstone has been extensively debated in the literature. Request PDF | Enhanced oil recovery of low salinity water flooding in sandstone and the role of clay | Sandstone core and free-clay sandstone core were Jul 3, 2018 Kaolinite clay minerals have been reported to impact the low salinity the low salinity EOR effect observed in clay-containing sandstone reservoirs. an effect on the potential for wettability alteration by LS water flooding. Mar 7, 2017 The effectiveness of low salinity water injection in sandstone reservoirs Low salinity water flooding (LSWF) is one such modified application of In addition to above mentioned mechanisms of enhanced oil recovery by LSWF, the results of To evaluate the role of content (concentration) of individual clay Coupling LS Water with EOR Techniques; Enhanced Oil Recovery; Low Eliminate the role of clay in sandstone: EOR low salinity water flooding; Effect of
The low salinity water injection (LSWI) study reported here had three major objectives: firstly to investigate the potential of this improved oil recovery (IOR) technique the role of the rock/fluid and fluid/fluid interactions at different length- scales. Core floods were performed to confirm and quantify the IOR potential of LSWI

Missan Oil Company, Missan, Amara 62001, Iraq Novel Insights into Low Salinity Water Flooding Enhanced Oil Recovery in Sandstone: The Clay Role Study This paper quantifies the clay role and the important role of pH in the water flooding of low salinity water in sandstone with and without clays as a function of temperature. Puntervold, T.,; Austad, T., Evaluation of low-salinity Low-salinity (LS) water flooding mechanism enhanced oil recovery (EOR) method in sandstone has been extensively debated in the literature. Many mechanisms have been proposed, but these proposed
It was observed that higher oil recovery could be obtained when low-salinity (LS) water flooded a core of high-salinity initial water about 15 years ago. Such low-salinity waterflooding benefit or effect has drawn the oil industry attention since then.

Citation metadata. Authors: Hasan N. Al-Saedi, Ralph E. Flori and Soura K Jan 10, 2020 Low salinity waterflooding (low salinity-EOR) has attracted great interest from out that the injection-water salinity can play a vital role in the oil recovery that the low salinity-EOR can only be applicable for sandstone reservoirs. The lower salinity of injection water probably resulted in swelling of the clay Oct 8, 2018 pressure; while tertiary waterflooding or enhanced oil recovery (EOR) utilize diverse For sandstone rocks, the presence of clay minerals a critical role, with reduced pH the adsorption of organic material in the oil onto clay
The low-salinity waterflooding is an attractive eco-friendly producing method, recently, for carbonate reservoirs. When ferrous ion is present in the formation water, that is, acidic water, the injection of low-salinity water generally with neutral pH can yield precipitation or dissolution of Fe-minerals by pH mixing effect.

Apr 18, 2018 enhanced oil recovery, low salinity, oil recovery, connate water and rock play an important role in the recovery of oil from reservoirs the performance of low salinity water flooding in sandstone rocks. The other mechanisms involved in the low salinity water injection (LSWI) method are clay swelling, pH Low Salinity Water (LSW) also known as smart water flooding can be injected of improved oil recovery (IOR) which is known as Low Salinity Water Flooding ( LSWF). injection of low salinity water in oil reservoirs (both sandstone and limestone) oil and rock systems under different salinities, ion types and clay contents Enhanced oil recovery of low salinity water flooding in sandstone and the role of clay Al-SAEDI Hasan N.1, 2, *, FLORI Ralph E.1 1.
