Abstract

The amount of shrimp shell waste is quite abundant in Indonesia, but its utilization is not optimal. Shrimp shells contain chitin that can be processed into chitosan. Chitosan polymer can be developed for Enhanced Oil Recovery. Testing the characteristics of shrimp shell chitosan has been carried out, but the recovery factor results in coreflooding are still very small. Additional characteristic tests such as adsorption tests are needed. This study was conducted to determine the characteristics of shrimp shell chitosan polymers by conducting tests such as compatibility tests, viscosity, adsorption. In this study, an experiment was conducted using biopolymer-chitosan with shrimp shell raw materials. The material for making formation water used NaCl with a salinity of 10,000 and 20,000 mg/L. The concentration of chitosan biopolymer was varied with 5,000, 10,000, and 15,000 mg/L. The size of the sand grains used was 60 mesh. The results of the tests that had been carried out all samples were declared compatible for use. The highest viscosity value was 1,055.19 cP and adsorption was 26.63 mg/g.

Abstract

The problem of sand and gas interference in artificial lift pumps is a serious problem. The ARD-22 well in Pangkalan Susu often goes offline due to sand and gas interference. Solutions to overcome sand problems by reducing drag force and mechanical methods. Reducing drag force by setting the well production rate below or equal to the critical sand flow rate. The mechanical method is carried out by adjusting the flow pattern on the artificial lift and also by adding a downhole tool in the form of a Cyclone, which functions to make the fluid flow from the reservoir turbulent so as to separate solid particles from liquid. Another dominant problem with this well is the rising GOR or gas interference which causes gas lock problems, so it is necessary to redesign the diptube as a separation area between gas particles and liquid fluid. The monitoring results from this research showed that the fluid flow from the sampling point showed that there was no intermittent gas and the dynagraph readings also showed normal results. Optimum production can be recovered according to the initial potential of G/N 50/45, production lifetime increased after installation diptube cyclone to reach 7 more months and increased company revenues totaled Rp. 8.306.660,000.

Abstract

Based on the analysis and calculations from daily production reports, there was a decrease in oil production of about 500 barrels of oil per year in the Widuri Field. The output of fluid produced occurred since drilling activities, completion of wells and production. In addition, other problems arise related to production optimization, namely excessive use of electrical energy in electrical submersible pumps, artificial lifts used to produce hydrocarbon fluids in Widuri Field with limited electrical energy capacity. ESP optimization can use VSD, because the ESP pump motor is an induction motor, where the speed is very proportional to the electric power supply. By adjusting the frequency of the ESP motor on the VSD, of course, you will be able to control the operation of the ESP in a wider range of capacity, head, and efficiency, so that you can determine the price of the desired optimum production rate based on 70% - 80% of Qmax. The optimization will be carried out in this research is to replace the ESP type with the number of stages and the number of new frequencies as well as calculating the lifting cost ratio. The purpose and objective of writing this research is to evaluate the volumetric efficiency of the pump that is being installed in the well so that optimization can be done in the study well by doing various ways and calculating the economic of each pump, that it gets the most economical lifting cost price. The method of this paper is the variation of stages and frequencies to get how much% volumetric efficiency, the Pump Discharge (P2) and Pump Intake (P3) methods to optimize the pump in the study well and Oil Lifting Cost for its economy. The conclusion is that you can determine which ESP pump to use based on the oil lifting cost.

Abstract

Polymer injection is one of the EOR methods using chemical which is injected into the reservoir to increase oil recovery. The polymer functions to maintain the flow of fluids, especially water, so that it does not boil ahead of oil towards production wells. This is due to the ability of the polymer to increase the viscosity of the fluid in the reservoir. The polymers commonly used in the petroleum world are synthetic polymers and natural polymers which are often referred to as biopolymers. The type of biopolymer in this article is Xanthan Gum while the synthetic polymer used is Terrafloc. The characteristics of these two polymers are compared so that the performance that will be obtained in an effort to increase the recovery of petroleum can be estimated. From the results of the viscosity measurement, it turned out that the Xanthan Gum polymer had a much greater viscosity value than the Terrafloc polymer. Thus, the use of Xanthan Gum and Terrafloc polymers can be adjusted to the needs related to the type of crude oil in the reservoir to be injected so that the results of obtaining petroleum can be optimal.
