Well test analysis was conducted to determine the characteristics of reservoir rocks. From the well test analysis it is obtained information such as permeability and skin factor. The skin factor is a quantity indicating the presence of disturbance in the formation as a result of drilling operations, production operations, perforating casing, gravel pack installation, remedial well work, acidizing operation, and hydraulic fracture operation. The objective of this research is to determine the relationship of multi rate test method of Jones, Blount, and Glaze and the comparison result among pressure buildup test and pressure drawdown test analyses, using Kappa software or manually calculation. Therefore, in this paper will study the method of Jones, Blount, and Glaze and the well test analyses to determine further work of the wells on block X. The data used in this paper is secondary data, namely the results of well test from three wells.Applying drawdown test analysis of A, Y, and Z wells yield skin factor values of 3.37; 27.10; and -1.39. Where in buildup pressure Horner method analysis of A, Y, and Z wells yield skin factor values of 16.10; 11.18; and -2.07. In the method of type curve derivatives the drawdown analysis of A, Y, and Z wells yield skin factor values of 7.04; 11.18; and 4.20. The analysis of pressure buildup, of A, Y, and Z wells yield skin factor value of 25.11; 14.47; and 1.93. In the analysis using Kappa software of A, Y, and Z wells yield skin factor values of 5.56; 10.2; and 2.00. The skin results of these wells indicate the formation damages. The Short Term Multiple Rate Flow Tests analysis using Jones, Blount, and Glaze method from the plots of Δp/q versus oil flow rate (q) are b’ high and b’/b low. These indicate that the three wells are encountering formation damages. The Jones, Blount, and Glaze method as well as the pressure buildup and pressure drawdown test analyses in block X indicate that these wells require to be stimulated.

Loss circulation is a major problem and known as the biggest challenge during drilling and well construction.This can leadsto various consequences,such as stuck pipe, loss of material and time to combat the losses, and even losing the well itself. Severe loss circulation conditions are often met while drilling geothermal wells in Indonesia. Partial to total losses have start experienced since drilling the surface section. Cement plugs is one of the conventional methods to cure losses. Number of cement plugs differ from one well to another well. Even in some wells, number of cement plugs performed for loss circulation plug can be over 30 times with total of more than 4,000 barrels of cement slurry pumped. Solution other than basic loss circulation material and cement plug must be developed to optimize curing loss time. Engineered fiber base concentration which is include; Base Fluid, LCM and Solid Package was obtained from simulation, then trial and error in laboratory was conducted. Based on the final recipe, the control pill was able to hold pressure and not leaking, even when using 5 mm grid clearance. Additional combined stiff fiber and flexible fiber with concentration of 6 lbs/bbl sufficient to hold exessive loss circulation.

Formation evaluation is a part of petroleum engineering to study reservoir characteristics as well as issues related to success in the discovery of hydrocarbon reserves. Hydrocarbon reserves are influenced by reservoir rock characteristics consisting of porosity (f), water saturation (Sw), and permeability (k.) In low resistivity regions are often found abnormalities in formation evaluation. The abnormality is a low resistivity value produced so that an inaccurate value obtained when water saturation is calculated. In this study, an evaluation process of the abnormality phenomena was performed on low resistivity areas. The evaluation is done by analyzing both log and core data. Evaluation in low resistivity areas aims to obtain a correction factor of the abnormality that occurs. Abnormalities in the calculation of resistivity values caused by the existence of conductive minerals which resulting in a decrease of the resistivity value of the formation. This correction factor can be used in Archie to calculate water saturations, therefore more accurate values of saturation were found.

Oil recovery may be increased by lowering interfacial tension between oil and water due to surfactant injection. Bagasse is one of the organic materials which has a fairly high lignin content, where lignin is the basic substance of making Natrium Lignosulfonate (NaLS) Surfactants. The research was divided into three sections. The first was experiment to produce lignin from bagasse. In this experiment 100 gram of bagasse with size of 60 mesh or 80 mesh extracted by benzene + ethanol (2:1) and then 20%, 50%, or 75% NaOH was added to activate lignin. The maximum amount of lignin produced was 24.88%. The second experiment was to produce NaLS surfactant from obtained lignin. FTIR equipment was used to verify the NaLS surfactant yielded using the method. The maximum amount of NaLS surfactant produced was 20.264% of bagasse mass. After that NaLS surfactant obtained from the previous process was used in chemical flooding experiment. In the experiments, the surfactant concentration in the solution was varied at 0.05%, 0.10%, 0.15%, and 1.00%. While temperature was set at 30°C, 40°C, 60°C, 70°C, or 80°C. The optimum condition happened when a solution with surfactant concentration of 1% was injected at 60°C. The recovery factor of oil using the condition was 0.47.

Drilling mud has a vital role in onshore or offshore oil and gas drilling operations with its primary function as the hydrostatic pressure to balance the formation pressure. There are some formations in Indonesia where the drilling hazards are extensive, but the problem that most likely to overcome is the shale/clay swelling. Today there is a water based mud called Polyamine Mud, a Polyamine mud has the advantages over conventional water base mud and also in some functions are as good as the Oil Base Mud. Some companies are still trying to adopt this technology into their drilling projects with various aspects to be considered and are wondering whether it will help them to drill a formation with shale/clay problem characteristics. A field location on the island of Sulawesi has drilled some wells on the Kintom formation using the Polyamine mud for a total depth of about 7,000 ft – 9,000 ft. The drill hole problem was not only the shale/clay swelling, but was also followed by some problems such as differential sticking and partial to total mud losses. The wells have now been drilled successfully and the gas production was above expectation. This paper will discuss a comparison of the Polyamine mud with the conventional mud system such as KCL-Polymer mud by doing some unconventional tests in the laboratory, including inhibition test, dispersion test, accression test, and bulk hardness test. After being tested in the laboratory, the Polyamine 3% mud system has drilled succesfully in some wells.

Permeability is one of the important of reservoir characteristics, but is difficult to predict it. The accurate permeability values can be obtained from core data analysis, but it is not possible to do at all of the well intervals in the field. This study used 191 sandstone core samples from the Upper Cibulakan Formation in the North West Java Basin. The concept of HFU (Hydraulic Flow Unit) developed by Kozeny-Carman is used to generate the relationship between porosity and permeability for each rock type. Afterward, to estimate the permeability value at uncored intervals, the statistical methods of artificial neural network based on log data are used on G-19 Well, G Field which is located in the North West Java Basin. Based on core data analysis from this research, the reservoir consists of eight HFU with different equations to estimate permeability for each HFU. From this reserarch, the results of permeability calculations at uncored intervals are not much different from the core data at the same depth. Therefore the approach of permeability prediction can be used to determine the value of permeability without performing core data analysis so that it can save the company expenses.
