Abstract

The rapid increase in groundwater exploitation in various sectors in Indonesia has caused preparations in the form of concrete steps that must be faced, especially reducing the impacts caused. The BRG area is an area known as an area in Geological Conditions the existence of intrusions that may result in retained groundwater flows and are productively small and even rare and in addition to that also in terms of environmental conditions of areas surrounded by large industries in the amount of very large groundwater use. Groundwater intake activities impacted the drawdown of groundwater levels. This study in cased the Water Balance conditions of the BRG area groundwater. This study employs hydrology variable to determine groundwater balance. Variables of Rainfall (CH in mm/yr), Evapotranspiration (ET in mm/yr), Infiltration (R in mm/yr) and Run Off (RO in mm/yr). Balance of Groundwater is based on a general formula of Capacity (S). Capacity (S) is directly proportional to Rainfall (CH) as Inflow and Total amount of Evapotranspiration (ET), Infiltration (R) and Run Off (RO) as Outflow. The study revealed that the inflow and outflow of water in BRG area are balanced. The results of the Hydrological Variables of the study area are as follows: Rainfall (CH) is of 8302 mm/yr average value, Evapotranspiration (ET) is of 2726,6 mm/yr average value, Infiltration (R) is of 2,02 x 107 mm/yr and Run off (Ro) 1316,3 mm/yr. The result of Groundwater Water balance is a negative value (Inflow < Outflow). Hydrological calculations decreased in each year for the last 4 years the observation data showed the negative values were getting greater, as follows: (a) the first year -4.01 x 107, (b) the second year -5.63 x 107, (c) the third year -3.10 x 107, (d) the fourth year -4.72 x 107.

Abstract

The production capacity of an oil and gas well is a benchmark in planning production equipment and increases the flow rate of production. In order to increase the rate of oil production, optimization is done optimally using ESP and it is predicted that the production time will be several years ahead. The method used in the well "AD-96" is the Wiggins Method 3 Phase IPR curve to increase the optimal production flow rate by continuing to predict IPR Future through a gradual decrease in reservoir pressure (Pr) scenario. IPR Future in this case provides a development to know the wells in the future. The results of the calculation of Wiggins IPR curve on the well "AD-96" obtained a maximum production rate (Qmax) of 2469 bfpd. To estimate the optimal production rate obtained from a percentage of 80% x maximum flow rate of 1975 bpd, the well is advised to use the Electrical Submersible Pump design with the ESP REDA type pump type DN1800 Pump Performance Curve 60 Hz, 3500 rpm and a Horse Power of 29 HP. , efficiency 76% and IPR Future with water cut of 80% each carried out in the calculation of 4 scenarios at 2000 psia reservoir pressure, obtained a target production flow rate (Qtarget) of 1326 bpd. It is known that the recommended production (recommended production) is between 1200-2400 bpd. Based on the IPR Future scenario, the result shows that ESP does not work at a pressure of 2000 psia.

Abstract

Hydrocarbon exploration currently has a variety of methods in operation to determine and identify a reservoir according to the required parameters. Well log data plays an important role in the development of hydrocarbon exploration. Hydrocarbon saturation can be known by first calculating the water saturation, so the value of Sw is the key to work to determine the type of reservoir and its fluid content at an interval or reservoir zone accompanied by crossover and separation readings on the density & neutron log curve. The research was conducted in the Jambi Sub-basin area, ANONIM field, South Sumatra, DS-19, CS-21, RS-23 wells with shaly sand lithology which produces three productive zones. Based on the results, wells DS-19, CS-21, RS-23 has a gaseous hydrocarbon fluid with Sw value in the DS-19 well of 10.5%, CS-21 well of 27.1%, and RS-23 well of 22.4%.
