Abstract

Surfactant flooding may increase oil recovery by lowering interfacial tension between oil and water. Bagasse is one of the organic materials which contain fairly high lignin, where lignin is the basic substance of making Natrium Lignosulfonate (NaLS) Surfactant. In this research, bagasse based surfactant was applied for surfactant flooding. The research was divided into two sections, namely: phase behavior test and NaLS Surfactant flooding where the water contained 70,000 ppm NaCl. Two surfactant concentrations which were used were 0.75% and 1.5% NaLS surfactant. Phase behavior tests were carried out to find the middle phase emulsion formation. Based on phase behavior test results, the percentage of emulsion volume for 0.75% and 1.5% NaLS is 13.75% and 8.75%, respectively. NaLS surfactant flooding was performed for to obtain the best recovery factor. FTIR equipment used determine recovery factor. The optimum condition was obtained at 0.75% NaLS surfactant concentration where the recovery factor was 4.4%.

Abstract

Formation water is a by-product of oil and gas processing. This formation water is very different from fresh water because formation water contains harmful chemicals and other elements contained in oil or gas. To prevent formation water from contaminating the environment, it is necessary to reduce the formation water content using an adsorbent. Some of the parameters that indicate reduced mineral and chemical content that must be considered for this research are pH, TDS (total dissolved solid), SG (specific gravity), and salinity values. In this study observed changes in these parameters with the administration of adsorbents. Two types of adsorbents used are bagasse and bentonite. The parameters of pH and TDS were measured using litmus paper and TDS paper respectively. While SG and salinity were measured using a salinity hydrometer. The process of giving the adsorbent causes a decrease in these four parameters. The addition of 3 grams of bagasse caused the pH, TDS, SG, and salinity of the formation water to decrease to 7.8, 3086 ppm, 1008 and 12 ppt, respectively. While the addition of 3 grams of bentonite caused these four parameters to decrease to 7.8, 2720 ppm, 1010 and 14 ppt respectively.

Abstract

The physical properties of the drilling mud greatly affect the success of the mud in lifting cuttings. The value of the physical properties of the drilling mud that is not in accordance with the required specifications can make cutting removal not optimal. In this study, an analysis of the physical properties of XCD Polymer and PHPA drilling mud will be carried out at temperatures of 100 oF, 200 oF, and 300 oF. This research is experimental which will test the characteristics or physical properties of the mud used. At the beginning of testing the physical properties of the XCD Polymer and PHPA mud using the initial composition of each of these muds, the results obtained did not fit into the mud specifications that had been determined due to the influence of the temperature increase. If you continue to use the same mud composition, the higher the temperature, some of the physical properties of the drilling mud will decrease. To overcome this problem, additives are added to the mud composition at each temperature to be tested. This is done so that the results of testing the value of the physical properties of the mud tested at each temperature are in accordance with predetermined specifications. After re-testing using the composition of the mud that has been added with additives, the results obtained from the two tested muds are the density value of 8.9-11.2 ppg, viscosity of 24-33 sec/qt, plastic viscosity of 20-33 cps, yield point of 21-28 lb/100 sqft, gel strength 10 seconds and 10 minutes respectively of 4-6 lb/100 sq. ft and 6-8 lb/100 sqft, filtration loss of 1.9- 4.6 ml, the thickness of the mud cake is 0.6-1 ml, and the pH is 9-10.
