Abstract

The oil and gas industry has an important role in the country, namely as a source of national budget revenue and as an energy provider. To meet the energy supply, it is sought to maximize production in the existing oil and gas field, so that an artificial lift of the Electrical Submersible Pump is carried out in the “D” and “Y” wells of the “NOAM” field. This study was conducted to calculate and analyze the economics of the “D”and “Y” wells of the “NOAM” field in the Electrical Submersible Pump project to determine whether the project is profitable to continue or not, and to find out what economic parameters can affect the profit. The results of the economic analysis of the “D” and “Y” wells, obtained from the “D” well, namely NPV of 4,009,400 USD, IRR value of 44.42% and POT value of 1.43 years. Meanwhile, the “Y” well obtained NPV -2,329,510 USD, IRR -24.62% and POT 3.07 years. From the sensitivity results using spider diagrams that have been carried out at the “D” well, the increase in total production and oil prices affects NPV and NCF, IRR is influenced by production, Capex, and oil prices and for GOI Take is influenced by Opex and oil prices. Whereas in well “Y”, production, Capex and oil prices affect NPV, IRR and NCF and GOI Take is not affected by changes in economic elements. From the results of the calculation and sensitivity analysis, the use of Electrical submersible Pump is economical to continue in well “D” while in well “Y” it is not economical to continue.

Abstract

Hydrocarbon production forecasting is the process of projecting oil or gas production over a period of time. One commonly used method is production modeling with Decline Curve Analysis (DCA). Many previous studies have used the Trial Error and Chisquare test method in DCA. However, this method has limitations including: long calculation time, modeling is done manually and not automatically, and the fit of the production curve with the data is often inaccurate. To overcome these limitations, a method that is fast, automatic and produces accurate curves with data is needed. One of them is the Levenberg-Marquardt Algorithm (LMA) numerical optimization approach. The Levenberg-Marquardt Algorithm method is an iterative method used to solve nonlinear optimization problems. The Levenberg Marquardt Algorithm method has advantages such as: reliability, fast convergence, and has been widely applied in engineering optimization problems. This study aims to forecast hydrocarbon production, calculate EUR (Estimated Ultimate Recovery) and ERR (estimated remaining reserve) at well HS-0105 AG field. First, a DCA program based on LMA was developed with the MATLAB programming language. After that, the production data is inputted into the LMA program to do production modeling until the optimum curve is obtained. After obtaining the optimum DCA curve, a comparison was made with the curve resulting from trial and error. From the results of DCA curve optimization with LMA, the RMSE (Root Mean Square Error) value = 101,756, R2 (R-squared) value = 0,574, computation time 2-3 seconds in the Levenberg-Marquardt Algorithm (LMA) method while the Trial Error and Chisquare test method RMSE (Root Mean Square Error) value 128.905 R2 (R squared) value = 0.569 and long computation time. From the comparison results, the Levenberg-Marquardt Algorithm (LMA) method is much better than Trial Error and is recommended for use. Based on the Decline Curve Analysis with the Levenberg-Marquardt Algorithm (LMA) method, the EUR (Estimated Ultimate Recovery) value is 14339,525 STB and the ERR (estimated remaining reserve) value is 7693,091 STB at the HS-0105 well in the AG field. With the results of this projection, it is expected that the production of the HS-0105 well in the AG field can be stimulated to withstand the rate of decline in production and even increase.

Abstract

Decline curve analysis: this method uses an exponential decline curve to describe the decline in reservoir production over time. This method utilizes historical production data to extrapolate and estimate the remaining reserves in the reservoir. So that the well in the field "Y" can be predicted using the decline curve. Trial Error and X2 Chi-Square Test method and obtained the value of the b exponent, namely 0 type decline curve Exponential, rate of decline (Di) 0.018616 and the smallest value of ∑X2 are 136.614. EUR is 1630,727 BOPD and ERR to limit is 1794,672 BOPD. The remaining production life is 136 months or 11 years.

Abstract

Well kick is the entry of formation fluid into the drill hole which causes formation pressure greater than the hydrostatic pressure of the drilling mud. The purpose of this study is to find out what factors cause a kick to occur, and how to repeat the kick using the wait and weight method. The wait and weight method is a kick countermeasures method with one circulation by new heavy mud. Steps to counteract well kick in the "MTM" well using the wait and weight method, namely by collecting drilling data, analyzing it with calculations of formation pressure when a kick occurs, hydrostatic pressure, KMW, ICP, FCP, maximum allowable mud weight, number of pump strokes , circulation time. Evaluate by comparing the calculation results with implementation data in the field, concluding the evaluation results. The results of the analysis of the implementation of well kick countermeasures using the wait and weight method obtained the initial formation pressure of 6888.16 psi, hydrostatic pressure of 6738.16 psi, KMW of 15.54 ppg, ICP of 1550 psi, FCP of 1431 psi, maximum allowable mud weight of 660.98 psi, total pump stroke was 0.1428 bbl/stk, and circulation time was 47,5 minutes. Well kick was successfully overcome using the wait and weight method.
