Abstract

These paper contains a highlight of laboratory experiment to evaluate the work of chemical for sand consolidation to strengthen the bonding between grains of rock while do not cause permeability reduction significantly. This experiment used reservoir rock and fluids to understand the interaction between the chemical solution and the reservoir rock and fluid. Firstly, the reservoir rock and fluid were analyzed their properties. The rock has been analyzed using CT Scan to drill the best representative core plug for the experiments, using SEM to identify the pore throat and pore geometry of the rock, using XRD to determine the minerals composition which mostly quartz. While the fluids have been analyzed for the anions and cations content, viscosity and other important properties. The brine particle content and also particle size distribution of the rock have been also over lied in the graph in order to know the possibility of bridging particle in the pore throat, but the graph looks good that no problem may arise from the bridging particle. Chemical for Sand Consolidation has been used in this experiment. Sand consolidation chemical normally contain plastic resin that has a property of bonding between solid materials. It sticks on the surface of solid materials and bonding together.The core flooding experiments have been run for 4 times, 2 times using synthetic cores and the other two using native cores. The experiments used synthetic cores reduce the permeability significantly. However, after cutting both ends of the core the permeability has indicated improvement. The other 2 experiments using native cores have reduced the permeability approximately 4 times down. The last two experiments have no cutting the ends of core for further experiments, so they cannot be compared to the first two experiment. So, the experiment procedures must be improved for the next evaluation, such as during curing time the rate of injected oil may be increased to reduce the adsorption of chemical to the surface area of the pore and also to hinder the flocculation of chemical in the pore space.

Abstract

Most of Indonesian oil fi eld had been categorized as mature fi led in which production had been declinedfor some time. Therefore EOR (Enhanced Oil Recovery) technology is a must to be implemented to thesekinds of fi eld. There are several EOR technologies had been employed successfully in laboratory and alsofi eld scales, including gas, thermal, and chemical injection. Most Indonesian oil fi elds have productivelayers depths below 2200ft that will not suitable for gas injection. So that chemical injections become animportant alternative that can be implemented to more wide range of depths. These technologies coveralkaline, surfactant, and polymer injection. This paper will highlight the selection and formulation ofsurfactant formulated from MES (Methyl Ester Sulfonates) produced from Palm Oils. These palm oils areavailable very abundant in Indonesia due to plenty farm palm oil in Indonesia. Normally Surfactants areformulated from petroleum sulfonates which are generated from petroleum base. By Using Surfactant that willbe manufactured from palm oil, it will be expected that the price will be cheaper compare to the surfactantfrom petroleum. A series of researches have been done to select the sources of palm oils, producing MESby sulfonation processes, and fi nally surfactant screening for EOR. Several types of MES produced fromvaries of palm oil taken from market such as: CPO (crude palm oil), several packed palm oils of differenttrademarks have been generated. These MES, then, have been given codes to differentiate among these MESsuch as: 1. CCO-MES (A), 2. CCO ME-MES (B), 3. Oleic Acid- MES (C), 4. Natrium Bisulfi t- MES1 (D),5. ME+H2SO4-MES2 (E), 6. CPO-MES (F). These MES production, then, have been formulated to becomesurfactant formula by adding some chemicals and solvent. After that alkaline ((Na2CO3) with optimizedconcentrations were added to generate the best EOR properties. All those Surfactant-MES have been testedusing Lemigas standard laboratory EOR screening; those are compatibility tests, IFT measurements, thermalstability, adsorption, fi ltration, phase behavior, imbibitions and core fl ooding. The result of the screening ofthe MES-chemicals mixtures shows that mixture of CPO-MES (F) with chemical and solvent with the mixturecomposition denoted as FChS811 has the best performance. 1% of this mixture has the best properties forEOR after adding 0.1% of Alkaline (Na2CO3). Laboratory test results indicates that fulfi ll screening criteriasuh as good compatibility and no precipitation, low IFT, thermal stability, low adsorption, low fi ltrationratio, Winsor type-I phase behavior, high RF on imbibition and core fl ooding tests. This Surfactant-MESmixture has a potential to be implemented for a fi eld trial with Huff and Puff method.

Abstract

Most of oil fi elds in Indonesian have been categorized as mature fi elds, since the primary stages of theoil production nearly fi nished. Therefore EOR technology is the only option to rejuvenate those old oil fi eldsto increase the oil recovery. CO2 miscible fl ooding, one of the proven EOR technology, can be implementedin some Indonesia oil fi elds if they fulfi ll the screening criteria for CO2 injection. Laboratory works initiallyshould be carried out to determine some parameters for calibrating the reservoir simulation program. Themost important parameter is MCMP (multiple contact miscibility pressure), this pressure level can be usedto determine the displacement effi ciency of the CO2 injection. Above the MCMP will be more effi cientcompare to below MCMP injection pressure. MCMP is normally can be obtained in the lab by a Slim tubeapparatus. In case there are no oil and gas sample available, some correlations based on the empiricalfi eld data are also available in the literature as well as EOS (equation of state) for predicting MCMP. Somereservoir fl uids MCMP have been evaluated using those three methods. Then, discrepancies were calculatedto compare the results of Slim tube tests, correlations and EOS calculation. Four correlations such as NPC(National Petroleum Council), Cronquist et al, Yellig-Metcalfe, Holm-Yosendal and one EOS modeling ofPeng-Robinson (1978) have been proposed to predict the MCMP fourteen reservoirs. Moreover, those MCMPwere also run using Slim tube. Holm-Yosendal correlation has nine reservoirs and secondly Yellig-Metcalfemethod possesses six reservoirs with discrepancy below 10% compare to MCMP obtained from Slim Tubetests. While the other methods are not appropriate as well as Peng-Robinson EOS modeling without anylaboratory data for calibration.

Abstract

Wettability plays an important role of two phase Àuids Àow in porous media. The displacement efficiency of oil by injected Àuid is also dictated by wettability characteristic of reservoir rocks. This papers contents a highlight of the reservoir wettability modification by injecting TFSA (Thin Film Spreading Agent) surfactant for EOR applications through a laboratory study . TFSA used in this study is called Coconut Ethanolamide with a HLB (Hydrophilic-Lipophilic Balance) level around 13 to 15 which is very suitable for TFSA purposes. Several laboratory evaluations have been done to screen this surfactant with the aim of getting the best properties that fulfill the criteria for EOR chemical injection. Then TFSA solution tests have been carried out including compatibility, thermal stability, phase behavior, and filtration test. The results suggest that all measured parameters are suitable for chemical injection. Others parameters measuring rock Àuid interactions for instance: adsorption, wettability, imbibition, relative permeability, and core Àood experiments has been done to find the quantitative numbers for screening this surfactant. All experiment results categorize as moderate levels for passing the screening criteria for chemical injection except for the adsorption which is excellent. Even though the results of laboratory tests show this TFSA is valid for chemical injection, improvement by adding some chemicals is still suggested to find a better TFSA formula.

Abstract

Carbon dioxide for enhanced oil recovery (CO2 EOR) can magnify oil production substantially while aconsistent amount of the CO2 injected remains sequestrated in the reservoir, which is benefi cial for reducingthe greenhouse gas (GHG) emission. The success of CO2 EOR sequestration depends on the proper sourcessinksintegration. This paper presents a systematic approach to pairing the CO2 captured from industrialactivities with oil reservoirs in South Sumatra basin for pilot project. Inventories of CO2 sources and oilreservoirs were done through survey and data questionnaires. The process of sources-sinks matching waspreceded by scoring and ranking of sources and sinks using criteria specifi cally developed for CO2 EORand sequestration. The top candidate of CO2 sources are matched to several best sinks that correspond toadded value, timing, injectivity, containment, and proximity. Two possible scenarios emerge for the initialpilot where the CO2 will be supplied from the gas gathering station (GGS) while the H3 and F21 oil fi eldsas the sinks. The pilot is intended to facilitate further commercial deployment of CO2 EOR sequestrationin the South Sumatera basin that was confi rmed has abundant EOR and storage sinks as well as industrialCO2 sources.

Abstract

MES (Methyl Ester Suffocates) can be formulated to become surfactant-MES that has surfactant potential properties for EOR (enhanced oil recovery). A such formulated surfactant MES by adding some solvents and chemicals to adjust its properties in order to generate a compatibity with reservoir fluid and rock has been developed. This formulated surfactant MES, therefore, has been tested its properties for enhanced oil recovery in a selected oil field. The oil field produces an oil withc39.45oAPI, and brine content of about 18,900 mg/L equivalent NaCl concentration. While reservoir rock is not available and substituted by Bentheimer standard core. Basically the production enhancements of surfactant solution for EOR processes are wettability alteration and interfacial tension reduction. In these experiments, some evaluations have been done to observe the capability the formulated surfactant MES for oil production enhancements includingwettability alteration and imbibition capability. Formulated low interfacial tension surfactant-MES that will be evaluated for spontaneous imbibition ability have been diluted in the brine of 0.5 and 1.0% concentrations. Tests on wettability alteration indicated that the surfactant solutions could not change the wettability of the rocks. The initial wettability is mixed wet and still mixed wet after ageing in the surfactant solution. On other hand the spontaneous imbibition tests resulted in significant oil production coming out from the cores, i.e. 67.07% oil recovery with 0.5% surfactant and 92.25% for 1.0% surfactant solutions. But optimum oil recovery factor by brine imbibition is only 41.69%
