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 CO 2 EOR sequestration depends on the proper sources-sinks integration. 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 industrialCO 2 sources.

Abstract

Carbon utilization in oil fi elds as EOR project has becomes main issue nowdays. Therefore preliminary CO2-EOR screening has been done for the oil fi elds laid on South Sumatra Basin, where CO2 emission arise from a number different sources of activities in South Sumatra area. Around 103 oil fi elds and consisting 581 reservoirs have been analysis to select which of those fi elds fulfi ll CO2 injection criteria. The criteria applied of the selection are based on EOR Screening Criteria Revisited papers introducing by J.J Taber at. All. 1977. The results of the screening are categorized as miscible, immiscible and failed for CO2 injection. Afterward, CO2 storage and incremental oil recovery due to CO2 injection were calculated using equation normally used in the oil industries. The incremental oil recovery due to CO2-EOR has been assumed as high as 12% of OOIP at miscible process and only 5% for immiscible displacement. The calculation of CO2 storage is based on the ultimate primary recovery for each fi eld in addition of the additional recovery due to CO2-EOR. Both primary and tertiary recovery have been used as the basic of calculating the CO2 storage. The results of the screening whether reservoir categories in immiscible, miscible injection and failed to fulfi ll EOR-CO2 injection criteria can be summarized as follow: 18 fi elds immiscible, 77 miscible, and 7 failed. Total incremental oil recovery estimate from CO2-EOR is approximately 480.5 MMSTB. While the total CO2 storages estimate are about 70 MMton for voidage replacement due to production at ultimate recovery and 22 MMton at EOR-recovery, so the total CO2 storage is approximately 92 MMton.

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

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 these kinds 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 calculated to 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

This laboratory experiment is a highlight of the preparation of ASP (Alkaline-Surfactant-Polymer Mixture) chemical injection for field implementation to determine the injectivity parameter and the effect of fluid properties change during flow into the porous media. Therefore, the experiments were focus on injectivity which is represented by permeability change. Besides, IFT and viscosity reduction, and also adsorption of injected chemical on the surface of pore throat were also investigated. ASP chemical solution has been prepared for experiments, the mixture consists of 0.3% of Surfactant-A, 1000 ppm Polymer KP and 0.2% alkaline of NaOH. This mixture has been evaluated the bulk properties for instance: IFT, viscosity and other parameter such as: compatibility, thermal stability, phase behavior, and filtration that are suitable for enhanced oil recovery for the target oil field. The next step is to examine the interaction between rock and injected fluid that may change the fluid and rock properties. ASP injection in carbonate rock in this experiment may result in permeability damage and almost totally block the pore throat. Reduction of permeability is very significantly approaching the value of PRF of level 88.76%. The damage could not be revocable after post flush of water that is indicated that the permeability reduction is permanent. Fluid properties of the ASP including IFT and viscosity show that the IFT looks constant and no signifycant change, on the hand the viscosity of the fluid drops down to almost 32.6% from the original. However, the adsorptions are still categorized as normal.

Abstract

Buton island as a potential area for conventional oil and gas, as well as asphalt/bitumen has long been the target of evaluation aimed at exploiting this potential, although to date no economic exploitation has been implemented. In this study, the potential of Buton asphalt/bitumen with mineable and in situ (non-mineable) status was studied and evaluated. In this study, qualitative and quantitative analysis have been carried out from Landsat 8 and Shuttle Radar Topography Mission (SRTM) data with the aim of identifying the presence of active faults and gravity due to orogenic processes. The lineament density pattern shows a general direction of NE-SW to NNW-SSE. The lineament process between satellite image data and gravity surveys helps efforts to identify the distribution of asphalt on Buton Island. Through combining distribution patterns of the Sampolakosa, Tondo, and Winto Formations, contain asphalt/bitumen, the study produces distribution of asphalt/bitumen accumulation in the region, both in surface/mineable and in situ categories. The 'best estimate' reserves obtained are 786.6 million barrels and 46 million barrels, respectively for asphalt/bitumen surface/mineable reserves and in situ/non-mineable reserves. It is hoped that this information regarding the potential/reserves of asphalt/bitumen on Buton Island may support efforts to exploit it
