Evaluation of the drainage area of a well is an effort to obtain success in planning field development. The size of the drain area not only affects the production rate but will also affect the distribution of pressure and saturation as well as the physical properties of the fluid and reservoir rock. Determination of optimum well spacing is important in field development management. This paper presents observations on the effect of the drain area on the production rate, pressure drop, and recovery factor. Simulation of the well model with a cylindrical drain area is used for various sizes of drainage areas. Based on the analysis in this study, it is concluded that the size of the discharge area affects the production rate, recovery factor, and pressure drop. The decrease in pressure affects the release of dissolved gas as indicated by changes in the gas-oil ratio (GOR) curve and the peak of the GOR.

Biogas is an alternative energy source that could solve two problems at once, the problem of environmentally friendly energy needs and the problem of waste treatment. One of the sources of biogas is obtained from anaerobic bacterial fermentation of cow dung waste. The biogas fermentation process produces impurities such as carbon dioxide (CO2) as a combustion inhibitor. Carbon dioxide will inhibit the combustion reaction, resulting in incomplete combustion. The biogas purification process is needed to reduce the amount of carbon dioxide in the biogas. The purification process is carried out using an absorbent compound of calcium oxide (CaO) to bind carbon dioxide contained in the biogas. Thus, the purpose of this study was to analyze the effect of the biogas purification process using calcium oxide on the characteristics of the diffusion flame produced by combustion. The research was conducted experimentally using the physicochemical-absorption method of purification by flowing biogas through a purificator device that contained a purification solution. After passing through the purification solution, the biogas was regulated at a fuel flow rate of 3 liters/min and then proceed to the bunsen burner. The results showed that purification affected increasing the characteristics of the diffusion flame combustion due to the reduced amount of carbon dioxide in the biogas. This is indicated by increasing the purification molarity, it also increases the flame speed of combustion and the flame angle, as well as a decrease in the flame height.

Barito Basin is known as one of hydrocarbon producing basin which is located in the Southeast Kalimantan. One of its prolific reservoir comes from sandstone facies of Tanjung Formation in the Paleo-Oligocene time. The sandstone undergone diagenesis, subsequently after deposition due to burial process. Burial diagenesis promotes further compaction, cementation and alteration which affect the reservoir quality. This study aims to assess the reservoir quality and its sensitivity against the diagenesis products. Research method was carried out by examine the core samples and scrutiny laboratory observation, such as Scanning Electron Microscope (SEM). X-ray Diffraction (XRD), porosity, permeability, grain density measurement and surface gamma-ray. The results show that the amount and type of alteration is vary by depth, age and lithofacies. Sandstones of sublitharenites and litharenites were buried to depths of 848.29 – 849.80 m and contained significant amounts of authigenic grain-coating and pore-lining clay as well as pore-filling zeolite cements. However, the underlying sandstones from 969.19 – 970.14 m depths exhibit less extensive alteration. In the early burial process, the reservoir quality is modified by the formation of secondary dissolution pores and minerals as a result of silicate dissolution during shallow burial diagenesis. The subsequent burial has reduced the pore spaces through mechanical compaction and cementtion. This study certainly valuable addition to our understanding about reservoir quality in correspond to the burial diagenesis.

One of the zeolite producing areas in Indonesia is Sukabumi. Natural zeolite originating from Sukabumi is composed of three main types of minerals: mordenite, clinoptilolite, and quartz. Zeolite as a catalyst can be improved by carrying out physical and chemical activation processes. Physically the catalyst can be activated by reducing the size of the zeolite through the grinding and sieving method. This physical activation process can increase the surface area of the zeolite. In this study, variations in the size of zeolite 80 mesh and 100 mesh were carried out that chemically activated by the acid activation method through immersion of natural zeolite with HCl and HF from this acid activation process it will increase the acidity of the zeolite. Measurement of functional groups and chemical compounds in activated zeolite using XRF and FTIR. The results of XRF analysis showed that the SiO2 content in 80 mesh zeolite was 69.5% and in 100 mesh zeolite was 82.1% and the FTIR analysis showed the presence of the C-H alkene functional group at a wavelength of 675-995 cm-1, ring C-H aromatic at a wavelength of 690-900 cm-1, C-O alcohol/ether/carboxylic acid/ester at wavelength 1610-1680 cm-1, functional group C=C alkene 1610-1680 cm-1, the O-H functional group is carboxylic acid at a wavelength of 3500-3650 cm-1 and an alcohol monomer/phenol O-H functional group at a wavelength of 3590-3650 cm-1.

Investigating wax formation tendencies in flow line for different rates of production will assist in decision making in determining the location of wax formation and point of wax modifiers injection. In this work, experimental and field data of Niger Delta field waxy crude oil samples were modeled and simulated with Multiflash and exported to OLGA software to investigate the wax formation tendencies in flow line. The properties of the waxy crude oil were modeled and characterized in multiflash and exported to OLGA. What if analysis of five case scenarios (Base case (14,000 bbl/day)), Production turndown case (10000 bbl/day and 12000 bbl/day), Production Ramp-up case (16000 bbl/day) and 18000 bbl/day) were run with Rygg, Rydahl, and Ronningsen (RRR) model for 100 days in a 16 inches flow line of 28500 ft length. For crude oil sample 1 with a production rate scenario of 14000 bbl/day (24,176 kg/s), the wax settles at a distance of 15625 ft from the wellhead. For a production rate scenario of 12000 bbl/day, the deposition is 303 ft closer than the base case. For the scenario of a flow rate of 10000 bbl/day, the deposition occurs 2871 ft closer to the base case. For the scenario of a flow rate of 16000 bbl/day the deposition is 4563 ft further from the base case. Meanwhile, for the scenario of a flow rate of 18000 bbl/day, the deposition of 7163 ft is further from the base case condition. Increase in the rate of production for the three crude samples prolong wax precipitation downstream the flow line. In addition, the thickness of wax deposited increases gradually with the production rate and exhibit a comparable relationship with the specific mass of wax. The precipitation rate is not linear with the rate of production and depends on other properties of the crude. Producing waxy crude at a higher rate will minimize wax formation and deposition tendencies in flow line in the field.

Field X is a marginal geothermal field located in the province of Maluku, Indonesia. An assessment of reservoir characteristics needs to be carried out to determine the appropriate field development method. The purpose of this study is to evaluate the electrical potential that can be generated from Field X. The Monte Carlo method is used to estimate the usable electric potential. The sensitivity of the parameters of generation time, initial temperature, and final temperature was carried out to get a wider picture. Based on the simulation results obtained a proportional relationship between reservoir temperature and electric potential. Higher reservoir temperatures can be obtained by drilling deeper wells. The most probable estimate (P50) of the electric potential of Field X is in the range of 0.141 – 0.248 MWe. An increase in the initial reservoir temperature of 15 oC causes an average increase of 16% MWe. Due to the relatively low reservoir temperature, low temperature geothermal binary power generation should be applied for field development.
