Abstract

Energy is vital to Indonesia's economic activities in various sectors. Energy plays an important role in the sustainability of the economic structure, which includes is the manufacturing industry. However, limited natural resources are one of the challenges for policymakers. Although energy conservation policies have been implemented in Indonesia since 1982, their enforcement in the manufacturing industry sector has not been solutive in supporting the development of the manufacturing industry in all regions. This study aims to determine the relationship between the development of energy intensity and economic growth in 26 provinces of Indonesia, using the growth and share analysis method from the data the authors have obtained. The results showed that the paper and printed goods, cement, and non-metallic minerals industries are the sub-sectors with high energy consumption. Then, Riau, DKI Jakarta, and West Java provinces are in the dominant quadrant for economic growth, but their energy intensity is in the low/slow quadrant. This indicates that industries in these three provinces have efficient use of energy.

Abstract

Well integrity failures may arise during the production phase of a well in a field. Those failures could create a Sustained Casing Pressure (SCP), a pressure that is measurable at the wellhead that can not be bled-off. SCP has to be addressed carefully to avoid any uncontrolled fluid flow to other formation or to surface. To maintain SCP value from degrading the other barrier integrity, the pressure threshold should be known and maintained for each annulus in a well. The maximum pressure threshold known as Maximum Allowable Annular Surface Pressure (MAASP). This case study will calculate MAASP from three wells in X field using three known method as outlined in API RP90-2 and ISO 16530-1. API RP 90-2 define two methods in calculation MAASP (known as MAASP – Maximum Allowavle Wellhead Operating Pressure), Simple Derating Method (SDM) and Explicit Derating Method (EDM). The result then compared and evaluted to know the differences, trend of MAASP for each methods, and create a generalization of MAASP/depth for field rule of thumb. For A annulus, the MAASP obtained using API RP90-2 SDM and EDM method is always greater than that obtained using the ISO 16530-1 method. However, for B annulus, the MAASP obtained using the API RP 90-2 SDM method varies, occasionally being greater or less than the ISO 16530-1 method. While in C annulus, the MAASP obtained using the API RP 90-2 SDM and EDM methods is always less than the ISO 16530-1 method. The MAASP/depth generalization will be presented for MAASP ISO 16530-1.

Abstract

A naturally fractured reservoir today plays a significant role in improved worldwide oil and gas production. More than half of the resource is mostly found in this reservoir. In this reservoir, there are two porous media: the matrix, which acts as the fluid source in this reservoir, and the fractures, which act as the fluid network that flows to the wellbore. Many authors have researched works to model this reservoir. There are two models are done in this study, such as Warren and Root model, where the fluid flow mechanism matrix to fractures is known as pseudosteady-state flow and the Kazemi-Gilman model is known as transient interporosity flow. Reservoir engineers generally utilize pressure transient analysis to determine this reservoir's characteristics. The purpose of this study is to assess whether it is feasible to verify the parameters of the reservoir for pressure transient analysis using a synthesis simulation model. It also aims to observe how reservoir parameters behave in relation to the characteristics of naturally fractured reservoirs by utilizing various values for porosity, permeability, and fracture spacing.

Abstract

The inability of the gas to lift liquid to the surface causes liquid to accumulate in the downhole, this event is called liquid loading, and sand deposits at the bottom of the well are caused to be swept away by the gas flow. If a well has liquid loading and sandification, well production will decrease and even the well will die. For this reason, it is necessary to carry out a predictive analysis of the well and a method to overcome the problem of liquid loading and sandiness using a plunger lift.Liquid loading is not always easy to identify, because the well is still producing significantly. The method used in the petroleum world to identify liquid loading is the "Turner et al" method. The plunger is a piston-type device that moves freely in the tubing and according to the inside diameter of the pipe, rising when the well pressure is sufficient to lift it and moving back down due to the force of gravity. The plunger lifting system uses gas pressure buildup in the well to lift the accumulated liquid column out of the well. The researcher conducted a liquid loading analysis on well A1 and well A2. From the results of the study it was identified that well A1 did not experience liquid loading, because the calculation results showed that the well's critical gas flow rate was 3.3 MMSCFPD which was less than the actual gas flow rate of 5 MMSCFPD. Well A2 is experiencing liquid loading, because the results of the calculation of the well's critical gas flow rate are 3.6 MMSCFPD, while the actual gas flow rate in the field is 3MMSCFPD.After removal of fluid and sand from the bottom of the well, the production rate of the A2 gas well increased to 5 MMSCFPD.

Abstract

The development of biomass-based renewable energy has received extra momentum due to the petroleum/coal-based energy crisis and global warming. Vacuum suction gasification is capable of creating combustible, power-generating synthesis gas. In this vacuum suction gasification, palm shells biomass and wood pellets performed better than rice husks. The production of synthetic gas was stable. It ran for 6.5 hours straight for the ability of palm shells and wood pellets to maintain sustainable temperatures in the reactor to maintain the gasification reaction. Rice husk was not suitable for this type of gasification. It did not maintain a suitable temperature for the gasification reaction to perform well. Value of heat losses in the lining of the reactor was large, more than 2,000 watts which might be the factor that prevented the rice husk from running well. Water was sprayed onto biomass at the reactor’s input to increase its hydrogen content. Oil palm shells responded well to this treatment. It produced better syngas output sustainably. The wood pellet was not responded well to water spray. It crumbled into small pieces. Rice husk is not responded well either. Syngas produced by the reactor was burned and used to boil water. In this gasification system, palm shells and wood pellets had apparent heat values of 5.62 kW and 5.41 kW, respectively. The efficiency of palm shells and wood pellets results in performances of 29.20 percent and 29.96 percent, respectively.

Abstract

Artificial intelligence techniques provide an alternative to conventional empirical correlation methods when experimentally determined oil formation volume factors (OFVF) are lacking. A new mathematical model is proposed using an artificial neural network (ANN) for estimating the OFVF for the Niger Delta crude oils. The method consists of two stages: data decorrelation through principal component analysis (PCA) and OFVF estimation through ANN. Data decorrelation was used to reduce redundancy in the data which decreased the number of neurons in the hidden layer needed for an ANN to achieve high accuracy. In the development of the model, 316 data points were obtained from the Niger Delta region of Nigeria. Application of data cleaning, outliers’ elimination and PCA analysis reduced the data to 243 points. 213 data points were used to develop the model of which 75% was used for training, 15% for validation and 10% for testing. The remaining 30 data points were used to test the predictive capability of the proposed model. The results obtained were compared with widely accepted empirical correlations of Standing, Glaso, Vazquez, Ikiensikimama & Ajienka, and Al-Marhoun. The proposed new model performed better than all of them in terms of coefficient of correlation, AAPE and RMSE. Hence the ANN model will reduce cost, save time, and also predict the OFVF of Niger Delta crudes with higher precision.

Abstract

The design of the fracturing fluid is a very important aspect of the success of hydraulic fracturing. The most common fracturing fluid used in hydraulic fracturing is the cross-linked guar gum fracturing fluid. To determine the optimal fracturing fluid concentration, it is necessary to analyze the fracturing fluid optimization to obtain the best fracturing results in terms of fracturing fluid rheology, regain permeability, hydraulics, cost, fracture geometry, and FOI. From this analysis, it is expected to obtain the most optimal fracturing fluid to be applied to the JARWO Well. This research was conducted by conducting a sensitivity test method for selecting the concentration of the fracturing fluid system that affects the fracture fluid rheology, regain permeability, fracturing fluid hydraulics during injection, total material cost, fracture geometry, and the resulting FOI. The sensitivity of the fracturing fluid concentration that was tested was the system concentration of 35 pptg, 40 pptg, and 45 pptg. Each fracturing fluid is tested in the laboratory to obtain rheology which will then be simulated using MFrac software to obtain the fracture geometry formed. The results of the analysis of the concentration of each fracturing fluid showed that the fracturing fluid with a system concentration of 40 pptg was the most stable in viscosity at pumping time to produce the highest FOI. The hydraulic fracturing fluid with a concentration of 40 pptg is better than that of a concentration of 45 pptg. From the performance of regaining permeability and residue, it is quite good when compared to fracturing fluid with concentration of 45 pptg, and the cost is lower when compared to a fracturing fluid with concentration of 45 pptg. So that the fracturing fluid with a system concentration of 40 pptg is the most optimal fluid for use in hydraulic fracturing activities at the JARWO Well.

Abstract

In month of August, year 2021, there was an alteration in the production-sharing contract for this field. The contract previously used was Production Sharing Contract (PSC) Cost Recovery, which changed to PSC Gross Split. This contract comparison aims to synergetically evaluate the comparison of the two economic models and also to determine a more efficient and appropriate scheme to be applied to field A, as well as to analyze the parameters that can affect the economic indicators of field A. The results of the economic analysis that has been carried out show that the PSC Gross Split scheme is better than the PSC Cost Recovery scheme. For PSC Cost Recovery, the Net Present Value (NPV) obtained for 30 wells is equal to 13,848,000 US$, the average Interest Rate of Return (IRR) is 118%, the average Pay Out Time (POT) is 1.43 years, the Contractor Take is 20,740,000 US$, and the Government Take is 176,587,000 US$. Whereas for PSC Gross Split, the NPV obtained for 30 wells was US$ 37,906,000, the average IRR was 245%, the average POT was 1.30 years, the Contractor Take was US$ 52,544,000, and the Government Take was 136,402,000 US$. The sensitivity analysis that has been carried out shows that the parameters of the amount of oil production and the price of oil have a significant effect on both schemes.
