“…(B.garrett, vankirk) 20 indicated that alkaline flooding needs high quality light water, therefore, ion exchange was widely performed in many fields of California for alkaline flooding at hardness levels of (2,000 ppm) where sodium cation is used to replace (Ca and Mg) on zeolite or organic gum.…”

In this research, a lab study was conducted on the process of injection a solution of Sodium Hydroxide (NaOH) into a lab-prepared a matrix Marble model that physically simulates the reservoir properties of the Jeribeh producing formation in DERO oil field. The Sodium Hydroxide (NaOH) solution is chosen due to its efficiency in studying alkaline. The injection operation of the alkaline was performed on the rock model using the volume ratios (15, 30 and 50% PV), (% PV that represents ratio of the injected liquid to the pores volume of the model), to guarantee an efficient displacement. The injection process was continued at each ratio using the displacement fluid until reaching the 250% PV level. Through the results of the displacement processes, the change of the following factors in relation with was graphically studied: where, Oil Displacement Factor (O.F.D), Water ratio in the produced fluid, (W) and: ratio of the produced oil volume at every injection process to the accumulated volume of the injected fluid at the same stage, (R.a=V_O/V_T ). To compare the displacement efficiency using Sodium Hydroxide with the efficiency of water injection (currently applied in DERO field), the model was flooded by (250% PV) of water after it was cleaned with kerosene, then dried and re-saturated with oil. A comparison between the change of the factors when injecting water and injecting Sodium Hydroxide solution was graphically performed. The results of the graphical comparison of both injection methods implied a steady increase of the (O.F.D) and (R.a) factors and a decrease of the water ratio produced with oil when injecting (NaOH) solution at all the studied injection ratios when compared with water flooding.

Oilfield produced water containing a high concentration of total dissolved solids (TDS) and hardness can successfully be softened for use as oilfield steam-generator feedwater. At the Belridge field in Kern County, CA, the combination of caustic softening and weak-acid cation exchange has been used to soften produced water containing 11,000 TDS and 550-ppm hardness to < I-ppm hardness. The resultant sludge containing calcium carbonate and magnesium hydroxide is concentrated by centrifuging and is disposed of in a landfill. Compared to the use of conventional strong-acid ion exchange followed by weak acid or weak acid followed by weakacid ion exchange systems, the process offers the benefits of lower capital and chemical costs, partial silica removal, and elimination of liquid waste discharge. This paper gives design parameters and operating conditions and discusses future applications in thermal recovery projects.
