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

The majority of petroleum production comes from the brown field where production has decreased from year to year in Indonesia. To increase the recovery factor of petroleum from the reservoir, an advanced step of production is required, Enhanced Oil Recovery (EOR), which can optimize the depletion of old oil fields. EOR is the application of technology that requires cost, technology and high risk. Therefore, before implementing EOR, in a field, we must carefully evaluate both technically and economically to obtain an optimal additional recovery. This research was conducted to increase oil production by injection of Methyl Ester Sulfonate (MES). This study begins with a screening parameter crude oil, formation water, Berea’s core, and determination of phase behavior, interfacial tension (IFT), thermal stability, imbibition, and core flooding tests. The result for concentratin optimum in 0.3% MES and had IFT 0.3267 dyne/cm. The results of core flooding tests are: Recovery factor of waterflooding is 33.95 % and recovery factor of MES injection is 4.19 %.

Abstract

In spontaneous imbibition researches, surfactant has been employed to control interfacial tension (IFT) and wettability. In this paper, the evaluation of grain size effect on spontaneous imbibition of surfactant solution is presented. In this work, the synthetic porous media (sand packs) with uniform and non-uniform grain size from 30 mesh to 100 mesh were made. The porous media were initially saturated by oil. Then they were immersed in brine with salinity of 62 to 40,000 ppm for 24 hours. After that, the porous media were immersed in surfactant solution with concentration of 0.2% for another 24 hours. The total oil recovery during these treatments was measured. The experiment was separated into three parts in order to investigate the effect of uniform grains, non-uniform grains, and salinity in spontaneous imbibition. The results show that grain size and porosity were proportional to oil recovery. In the case of porous media with uniform grain size, the effect of grain size on recovery factor is stronger than that of porosity. Meanwhile the salinity has an the optimum condition for a maximum recovery factor. In this study, it happened at salinity of 20,000 ppm. Oil recovery factors observed in this study ranged from 66.7% to 91.1%.

Abstract

Field Z is a mature oil and gas field with several production facilities that have passed their service life design, re-assessment of service life for the critical equipment is needed to carry out. This study focuses on identifying the damage mechanism, determining the residual life assessment, and assessing the effect of pressure and temperature on the residual service life of four separators in field Z. The approach is to recalculate the maximum allowable pressure and the minimum thickness of the separator, estimates the corrosion rate using API 510 and API 581, and estimates the residual life assessment of the separator. The result shows that estimation of corrosion rate with API 581 provide lower value than API 510 due to different methodology. However, the result prove that the operating pressure and temperature of separator will affect to the residual life through minimum thickness and corrosion rate, respectively. The higher operating temperature, the higher corrosion rate. Both of these will reduce the residual life. The calculation estimates that at current operation condition, three of four separators in field Z still can be utilize d at least until next five years. While one separator needs to replace immediately considering to the negative remaining service life.

Abstract

One of the efforts that can be done to evaluate the performance of water injection in a field is by monitoring the injector wells. Observations can be made by looking at the flow rate and injection pressure at each injector well. The response given by each injection well will be able to represent the injection performance on a field scale. The EX structure is a structure that has been produced for more than 40 years. In addition, water injection has also been applied for approximately 16 years. There are four injection wells operating in this EX structure with an average injection flow rate of 3000-8000 bwipd per well. Evaluation of injection well performance is carried out by conducting a Hall Plot on each injection well from the start of the injection process to the last data obtained. Based on the evaluation results, it was found that there was plugging in the EA-IIS and EJ-IVS injection wells. Stimulation activity is needed in both wells to restore the well injection capability. Meanwhile, for the EA-IS and EB-IIL injection wells, there are no significant problems in those wells so they can still function properly as injection wells.

Abstract

The Enhanced Oil Recovery method is a method that can be attempted to increase the recovery of petroleum. One of the materials that can be used is Methyl Ester Sulfonate surfactant from palm oil, as a vegetable surfactant whose raw materials are widely available in Indonesia. In this study, the compatibility test of Methyl Ester Sulfonate surfactant was carried out on light crude oil type T samples. The study was carried out with various surfactant concentrations, starting from 0.25%, 0.3%, 1%, 1.5%, and 2%. In the aqueous stability test, the results obtained for all clear conditions for the surfactant concentration were measured for 3 days in an oven with a temperature of 60oC. Whereas in the phase behavior test, good results of the upper phase emulsion were obtained at concentrations of 0.3%, 1%, 1.5%, and 2%. The volume of the top phase emulsion ranges from 25% to 37.5%. (Normal). From the results of this study, it can be concluded that for the crude oil sample T, palm oil MES surfactant is stable for use as a surfactant injection fluid, with a surfactant concentration composition that produces a fairly large upper phase emulsion of around 25% - 37.5% at a surfactant concentration of 0.5% - 2%.

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.

Abstract

Polymer injection is one of the EOR methods using chemical which is injected into the reservoir to increase oil recovery. The polymer functions to maintain the flow of fluids, especially water, so that it does not boil ahead of oil towards production wells. This is due to the ability of the polymer to increase the viscosity of the fluid in the reservoir. The polymers commonly used in the petroleum world are synthetic polymers and natural polymers which are often referred to as biopolymers. The type of biopolymer in this article is Xanthan Gum while the synthetic polymer used is Terrafloc. The characteristics of these two polymers are compared so that the performance that will be obtained in an effort to increase the recovery of petroleum can be estimated. From the results of the viscosity measurement, it turned out that the Xanthan Gum polymer had a much greater viscosity value than the Terrafloc polymer. Thus, the use of Xanthan Gum and Terrafloc polymers can be adjusted to the needs related to the type of crude oil in the reservoir to be injected so that the results of obtaining petroleum can be optimal.
