The decline in production from of a field is the common problem in the oil and gas industry. One of the causes of the decrease in production is the decline of reservoir pressure. Based on the analisis result, it was found that SNP field had a weak water drive. The most dominant drive of the field was fluid expansion. In order to reduce the problem, a reservoir pressure maintenance effort was required by injecting water. In this research, the effect of water injection to reservoir pressure and cumulative production was analyzed. From the evaluation result, it was found that the existing inejection performance using one injection well to Zones A and B was not optimum. Because, the recovery factor was predicted to 29.11% only.By activating the four injection wells, the recoverty factor could be increase to 31.43%.

Flow regime analysis on the results of pressure build-up Z-01 well test was conducted to determine the type of flow that occurs in each time region section. In the early time stage there is a flow which is dominated by linear flow which is then followed by bilinear flow. At the middle time there is a radial flow where the pressure disturbance has spread towards the reservoir. In the late time flow stage is dominated by steadystate flow where the flow is affected because there is a support pressure caused by the constant pressure boundary. In the analysis of pressure build-up used to determine reservoir parameters can be used in the middle time region. This is used because the plot results between ΔP vs. log HTR (Horner Time Ratio) are straight lines which can be used to calculate reservoir parameter values such as permeability (k), formation damage factor (s). This test was analyzed using the Ecrin software and obtained a dual porosity model with a permeability value of 4.8 md, skin -3.57. From the analyzed model, it is obtained that the well fracture-finite conductivity model means that the Z-01 well has been stimulated to increase production.

A multiphase flow system is commonly faced by oil and gas industries where it constituted of complex design and analysis [1]. Previous studies on the multiphase system have established a number of models including Hagerdon & Brown, Duns & Ros, Orkiszewki and Beggs & Brill [1]. Numerous studies have been carried out on the multiphase system related to production engineering [3]. However, the study on the multiphase system is found limited to be related to well control and drilling management. The multiphase system is interestingly important in well control especially during unwanted circumstances such as kick. Flow behavior and pattern might be different from one phase system where normally only gas kick is considered during design stage of the drilling campaign. Since the multiphase kick might represent different outcome compared to one phase system, an accurate calculation of multiphase kick is desired. Therefore, the purpose of this study is to observe the impact on the multiphase kick with on the pressure drop reading and its connection with a circulating system. The study will cover on Pressure drop calculation using Beggs & Brill correlation by consolidating all the data given from various sources; Identification of flow regime of the multiphase system for the base case with several reference pressure; Sensitivity analysis including the effect of different liquid content and liquid flow rate towards the pressure drop. The expected outcomes from this study are beneficial for well control management where necessary actions to prevent blowout.

In thisresearch the application of permanent magnet motor and asynchronous motor in X Well was evaluated. The permanent magnet motor and asynchronous motor used in this research are PM51 – NFO 150 FLT @50hz and AM51 – NFO 150 FLT @50hz, respectively. Several parameters are compared such energy losses, energy consumption, motor heating, and production rate. Based on the data analysis, there are some advantages by using permanent magnet motor which can help to improve efficiency and consume less energy, therefore can give more profit within the same period of production. These advantages consist of durability for motor, consume less electricity energy to maintain the operation of ESP string, give bigger production rate, and longer expected life time than an asynchronous motor. The implementation of permanent magnet motor is recommended in oil well that has high fluctuation in production flow rate, since the setting flow rate of the motor is adjustable. This advantage can be useful to give longer lifetime and hence to reduce the pump replacement program

In this paper, a numerical study was conducted to investigate the effect of spatial heterogeneity of multiple porosity fields on oil recovery, residual oil saturation, polymer retained, and polymer adsorption. The generated porosity fields were applied to UTCHEM for simulating polymer and water flooding in heterogeneous two-layered porous media. From the analysis, the increase of reservoir heterogeneity resulted in higher polymer retention and lower polymer adsorption. In general, polymer flooding results in more balance residual oil saturation in the upper and lower layer than water flooding. This indicated that the vertical sweep efficiency of polymer flooding was better than water flooding. Residual oil saturation ratio between layers after water or polymer flooding was about equal along with the increase of reservoir heterogeneity. Spatial heterogeneity of multiple porosity fields had only a small effect on recovery factor. The variation of the recovery factor of polymer and water flooding due to the reservoir heterogeneity was under 1%.

Naturally fractured reservoirs have an important role in the production and reserves of hydrocarbons, where more than 40% of the oil and gas reservoir production comes from this reservoir type. There are two systems that affect the production mechanism in this reservoir, namely the matrix as a fluid source and fractures as a fluid transfer network to the wellbore. This study discusses the characterization of naturally fractured reservoirs using curve type matching. In this study, the Warren and Root model is applied to create a reservoir model that applies the fluid flow mechanism from the matrix to the fracture with pseudo steady state interporosity flow. Pressure transient analysis is commonly known and widely used by reservoir engineers as a tool to identify reservoir characteristics, where there are two important parameters that influence reservoir productivity, namely the ratio of the storativity coefficient (omega) and the interporosity flow coefficient (lamda). Based on the results of the analysis, it is found that the coefficients are strongly affected by the values of porosity fracture and permeability fracture also the productivity of the reservoir.

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.

The Enhanced Oil Recovery (EOR) method aims to increase oil production. One of the EOR methods is CO2 injection. CO2 injection mechanism is by expanding the volume of oil, reducing viscosity, and reducing the mobility ratio. The purpose of the study was to compare the recovery factor gain in the waterflood, Miscible CO2 Continuous injection, and Miscible WAG CO2 injection methods with a three-dimensional simulation methodology using CMG Compositional software in the CW Field. From the CW field, a sectoral model was chosen to be studied, namely the area of the CW-A well and the CW-B well because the two areas have different reservoir conditions. The optimal injection well pattern for the CW-A Well area and the CW-B Well area is Inverted Five Spot. CO2 injection is said to be miscible because the injection pressure and reservoir pressure are above MMP (2800 psi) and mixing occurs between CO2 and oil to form a homogeneous phase. The optimal CW-A (Low Permeability) well area using the 4 PV CO2 Continues Injection scenario (injection rate 31.8 Mscf/d) produces an RF of 61.18%. Optimal CW-B (High Permeability) Well Area using CO2-WAG 2 PV injection scenario in 90 days (3 months) cycle, WAG Ratio 1:3 (injection water rate 20,036.84 bwpd and gas injection rate 33.75 Mscf/d) produces RF of 61.76%.

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.
