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

Material Balance method is a concept of material equilibrium with measurement of response from reservoir (pressure) due to production, injection, and influx activities so that it can calculate the appropriate Original Oil in Place. By creating a material balance model, it can be done the development plan of Batang Field with the aim of obtaining cumulative optimum oil production. Batang Field is still feasible to be developed using pressure maintenance scenarios seen from OOIP of 144.3 MMSTB, Recovery Factor of 14.9% and Current Pressure of 70-80 psi.  Pressure Maintenance is a water injection with the aim of replacing the fluid that has been produced so that it is expected to keep the reservoir pressure from falling. Ideally this method requires Voidage Replacement Ratio (VRR) = 1 as the target injection. Economic calculation using Cost Recovery from this scenario shows a positive NVP ($ 2,865,000 USD). Therefore, development projects using Pressure Maintenance can be applied in the field. With this paper, it is hoped that it can increase reserves and  lifespan of the Batang oil field.
