Abstract

This research is done in PT Geo Dipa Energi Dieng, Banjarnegara Regency, Central Java Province. The consideration is PT Geo Dipa Energi Dieng is one geothermal power plant in Indonesia which has the characteristics of reservoir double phase with water dominated, so interesting to be the place of the research because the equipment production is complex. The method of calculation in this research by using Mass Balance and Weir Box method which is used to calculate the flow rate of geothermal fluid production, the potential of wells and the amount of power electricity generated. Geothermal flow fluid flow rate calculation is very important and must be done at any time, since the production of geothermal wells must be tailored to the needs, the production equipment and the power plant equipment which can be arranged by using the wellhead. Based on Mass Balance and Weir Box Method, the calculation of vapor and brine mass flow rate from January 1, 2017 to February 22, 2017 obtained the average value of vapor mass flow rate (MVapour) is 29.4785 tons / hour, water flow rate of mass (MBrine) is 44.31 tons / hour, total fluid mass flow rate (MTotal) is 73.782 tons / hour, vapor fraction is 39.94688%, brass fraction is 60.05312%, flowing enthalpy is 1620 kJ / kg, potential The total well (gross) is 33.205 MW. The net potential is 13.2653 MW, resulting in 3.93 MWe of electricity. Keywords: Flow Rate, Electricity, Mass Balance, Potential Well And Weir Box

Abstract

The methods of lifting fluid from the well to the surface consists of natural wells method and artificial lift method. One type of artificial lifting is Hydraulic Pumping Unit (HPU) method. In this case, well ALF-04 as the HPU well in Kawengan field which faces lower actual production compare to its theoritic production calculation then decided need to be redesigned. The objectives of redesigned is to reach optimum flow rate of the well. Recently actual flow rate of this well is 309.2 bfpd, and then the result of IPR calculation by Vogel shows the Q max is 957.25 bfpd, it means this well production is still feasible to be optimized till approximately 765.8 bfpd. After redesign calculation , obtained pump setting  depth 755 m, plunger size of 2.5 ", 120" stroke length, and speed of 6 spm, pump displacement 568.425 bpd. For the rod diameter was changing from 0.75 inch to 0.875 inch with total length 2395m , it greatly affects the maximum stress value of 22,774.03 psi, and also has an influence to the increasing of PPRL value of 8243.26 lb, and the MPRL value of 3000 lb.

Abstract

PT Bukitapit Bumi Persada is a company engaged in oil well service including cementing, stimulation, fracturing, coiled tubing unit and nitrogen service. Hydraulic fracturing is a stimulation activity to repair wells due to damage to the formation by injecting fracturing fluid at high pressure to create channels and held with proppant so that the fractures formed do not close again. The TLJ-250 well in the Prabumulih field was stimulated using hydraulic fracturing on Sunday, April 24, 2022. The TLJ-250 well has sandstone lithology with low permeability of about 4 mD with a porosity value of 12% so that this well is not productive to produce hydrocarbons. The fracturing fluid used is water base fluid, which is a water-based fracturing fluid and the proppant used is carbolite 20/40. The process of hydraulic fracturing begins with a breakdown test, step rate test, mini frac, and main frac with the stages of injecting proppant starting with pre-pad, slug, pad, and flush. The reason for hydraulic fracturing in the TLJ-250 well is that the ex bore well is less economical when producing. After hydraulic fracturing, TLJ-250 well experienced an increase in permeability value of about 904.15 mD with an average permeability around 22.32 mD followed by an increase in productivity index (PI) with the Prats method around 3.75 and the Cinco-Ley method is around 3.57 times. The production rate at TLJ-250 well is 158 BFPD with oil production of 21 BOPD
