Experimental Study Of Low Salinity Water Flooding And Fracturing Effects In Low Permeability Carbonate Reservoir, Benny Arianto Harahap

Theses

In past decades, there were numerous research works demonstrated that salinity alteration of injected water could enhance the oil recovery. Low salinity water (LSW) injection is a type of Enhanced Oil Recovery (EOR) method, which attracts the industrial, and researchers because of its simplicity to use the implications,

Environment-friendly nature, and less cost. In addition to, hydraulic fracturing, also known as hydraulic stimulation, is another EOR method that improves hydrocarbon flow by creating fractures in the Low Permeability Formation (LPF) that connects the reservoir and wellbore. Fractures will increase the permeability of reservoir and give the flow path for hydrocarbon …

Oil Recovery By Surfactant Flooding; Sensitivity Analysis To Technical Parameters And Economic Analysis, Hadel Mohsen Moustafa

Theses

Various enhanced oil recovery methods including miscible gas injection, chemical, thermal and other methods are applied at the third phase of production after the primary and secondary recovery have been exhausted. Surfactant flooding is one of the chemical methods that is capable of recovering more oil by decreasing the IFT and/or wettability alteration.This piece of work aims to asses and select the development options using surfactant process that maximize oil recovery for a synthetic reservoir model by optimizing technical and economic analysis.

Reservoir simulation study using ECLIPSE 100 was used to study the different development options of surfactant flooding applied …

Evaluation Of Electrocoagulation For Chloride And Ammonium Removal From The Reject Brine Effluent Pretreated By Solvay Process, Miada Abubaker Ali

Theses

Excessive use of desalination, due to the increase in freshwater demand, results in large productions of reject brine. Therefore, the development of an efficient treatment process of the reject brine becomes vital. The Solvay process is one of the main treatment technologies, wherein NH₃ is introduced to convert soluble Na⁺ into insoluble NaHCO₃. However, in this process, Cl^- is not removed and NH₄⁺ is introduced, and therefore electrocoagulation has been proposed for their removal. The experiment was designed using Minitab with different initial concentrations of chloride (7400 – 32600 mg/l), current densities (0.033 …
