Secondary Oil Recovery

Abstract One of the most crucial problems that the petroleum industry has been facing for quite some time, is the damage done to the sandstone formations by the produced water that is pumped into the ground during secondary oil recovery. The drastic reduction in permeability of these sandstone beds due to the water-shock, is a great concern in petroleum industry. The changes in produced water composition has made secondary oil recovery difficult. The decreasing permeability of the bed, increases the pumping and equipment cost to a great extent. The control of clay release is essential to the economic and effective operations in many oil fields. The main topic of this research is the effect of electrolytic composition in produced water on the clay particles pumped into sandstone formations or through sand-filters. Earlier studies [1–5] have revealed that high pH and low salt concentrations of water lead to release of clay from sand-grains. Also, there might be some clay particles injected into the ground with the produced water. These injected clays get captured by the sandstone bed. Both the release and capture of clays changes the porosity of bed and the surface area of sandstone particles and thus, reduces the permeability of the bed drastically. This paper just presents the experimental work done to predict the release of indigenous clay in the sand filter in aqueous phase flow. Future work will concentrate more on actual filtration experiments to release of indigenous clays and capture of injected clays in aqueous phase flow and the release-capture phenomena in two phase flows as well. In produced water operations, oil companies need to remove particles from the injection water to avoid formation damage. Consolidated Sand Cartridge filters are an inexpensive alternative compared to tradition means of filtering the particles. This work demonstrates the capability and advantages of these filters. The filter has properties similar to that of sandstone and so, results of clay migration study for the filter may be similar to sandstone bed as well. The Consolidated Sand filter is superior compared to conventional cylindrical sand filters in that its outer surface is expanded out into a six-lobe geometry with a larger surface area for filtration. Hence higher flow rates are achieved through the filter at a given pressure drop and the life of filter increases. Also, it has a glue bound sand structure which reduces the release of clay compared to the conventional sand filters. However, the disadvantage of the filter is that it is bulky and heavy and it adds to the disposal cost for the user. This work serves the dual purpose of characterizing the consolidated sand cartridge filter and also, studying the phenomena of clay release and capture in the sand filter to determine the optimum combination of pH and salt-concentration for minimal permeability loss. The phenomenon of clay release and capture is explained on basis of zeta potential of the particles, which characterize the surface charge of the particles.

Nowadays, oil-in-water (O/W) emulsion has become an important topic in many industries. Petroleum industry is one of these industries. O/W emulsion produced in crude oil recovery causes problems at different stages in petroleum industry. Produced water can not be injected again into the well, because it contains high concentrations of oil, grease and suspended particles. Recently, membrane technology has been applied in separation of O/W emulsion. One membrane that has been developed special for oil filtration is slotted true surface filter. This research investigated influences of pore size and initial concentration of feed emulsion during oil filtration using slotted pore membrane. From the experiment, oil rejection will be higher if we use membrane with smaller pore size, emulsion with high stability and small trans membrane pressure. Based on the slot width it can be concluded that 33 microns membrane gives better oil rejection than 80 microns membrane. Initial concentrations of challenge emulsion also influence value of flux and oil rejection, which will also influence our decision to choose suitable membrane in relation with hydrophilicity of the membrane. During microfiltration process, there was deformation of oil particle through slot of membrane, which can be analyzed by observing size of oil drops in feed and permeate sides. Keywords: emulsion, microfiltration, slotted pore membraneAbstrakSaat ini penanganan limbah emulsi minyak dalam air menjadi topik penting di berbagai industri. Salah satunya adalah industri perminyakan. Emulsi yang dihasilkan dalam proses penambangan minyak mentah menimbulkan masalah pada beberapa tahapan proses di industri. Air yang mengandung minyak tidak dapat digunakan kembali untuk meningkatkan perolehan minyak karena mengandung minyak, lemak dan partikel tersuspensi dalam konsentrasi tinggi. Sehingga dibutuhkan proses pemisahan emulsi minyak dalam air. Akhir–akhir ini teknologi membran telah digunakan untuk memisahkan emulsi tersebut. Salah satu membrane yang dikembangkan adalah membrane berslot seperti yang digunakan dalam penelitian ini. Penelitian ini telah berupaya mengamati pengaruh variasi ukuran pori dan konsentrasi umpan terhadap performa membrane berslot dalam memisahkan emulsi minyak dalam air. Dari percobaan, diperoleh hasil bahwa rejeksi membran terhadap minyak meningkat jika digunakan membrane dengan ukuran ori lebih kecil, emulsi dengan kestabilan yang tinggi, dan beda tekanan yang kecil. Disimpulkan bahwa membrane dengan ukuran pori 33 mikrometer memberikan rejeksi membrane lebih tinggi dibandingkan membrane dengan ukuran pori 80 mikrometer. Konsentrasi awal umpan mempengaruhi fluks dan rejeksi serta mempengaruhi pilihan kita dalam memilih jenis membran yang digunakan. Selama proses filtrasi, terjadi perubahan bentuk atau deformasi partikel minyak melewati slot atau pori membrane yang diamati melalui distribusi ukuran partikel.Kata kunci: emulsi, mikrofiltrasi, membran berslot

Electrochemical Removal

Petroleum produced water (PPW) is a waste-stream that entails huge cost on the petroleum industry. Along with other suspended and dissolved solids, it contains sulfate, which is a major hurdle for its alternative use intended toward enhanced oil recovery. This study proposes a two-step process for sulfate removal from PPW. A synthetic PPW was designed for the study using response surface methodology. During the first step, sulfate present in PPW was reduced to sulfide by anaerobic fermentation with 80% efficiency. In the second step, more than 70% of the accumulated sulfide was electrochemically oxidized. This integrated approach successfully removed sulfate from the synthetic wastewater indicating its applicability in the treatment of PPW and its subsequent applications in other oil field operations.
