Abstract

Well M field R is one of the wells located in the Rokan Working area. Where this well is an old well that wants to be reactivated by adding new perforation zones at intervals of 5,000 ft - 5,100 ft. In carrying out this work, formation pressure analysis is very necessary so that the activity of adding new perforation zones can run well and smoothly. The initial formation pressure in the well was 2,166 psi with a hydrostatic pressure of 2,253 psi. This means that the well is not experiencing a kick. However, after the new zone perforation work was carried out, the formation pressure which was initially 2,166 psi increased to 2,300 psi. causes formation pressure to be greater than hydrostatic pressure, namely 2,300 psi > 2,253 psi. The greater the formation pressure than the hydrostatic pressure indicates that the well is experiencing a kick problem. Workover fluid planning for the M well in the R field consists of 2 types of calculations, namely concurrent calculations and bullheading calculations. In concurrent calculations, to resist a formation pressure of 2,300 psi a kill weight fluid of 8.85 ppg is required with a total workover fluid volume of 235 bbl and a total stroke of 7,070 stk and requires a pumping time of 236 minutes. Meanwhile, in the bullheading calculation, to resist a formation pressure of 2,300 psi, a kill fluid weight of 8.85 ppg is required with a total workover fluid volume of 101 bbl and a total stroke of 3,040 stk and requires a pumping time of 102 minutes. If you look at the results, bullheading calculations are more profitable than concurrent calculations. However, if you look at the condition of the well, these two calculations are very different. This is because concurrent calculations are carried out when well conditions allow a circulation system to be implemented. Meanwhile, bullheading calculations are carried out when well conditions do not allow for a circulation system.
