Abstract

Decline curve analysis often used to determine remaning reserves in a reservoir. To analyze with this method, the decline type curve from production period (trend) must be known. To determine decline type curve, in this paper will use two methods there are: trial error & x2 chisquare test and decline type curve matching. Both of methods have different way to determine decline type curve. Trial error done by making tabulation and calculation, while decline type curve matching done by overlay. The calculation are aimed to determine decline type curve, Remaining Reserves (RR) and Estimate Ultimate Recovery (EUR). Analysis done by taking sample of data well X which is a new well produced since September 2013 till the last data is Febuary 2016. First step of this study done by making type curve from equations and assumptionin literature then plot production rate vs time and choose production period (trend) to be analyzed. After that, determine decline type curve by trial error and decline type curve matching and do forecast until get remaining reserves and estimated ultimate recovery if economic limit rate production known. From calculation of both methods, resulted exponential decline type curve. For the error method obtained RR  41322,3 STB and EUR 240328,9 STB, while for decline type curve matching obtained RR 40534,2 STB and EUR 239540,8 STB

Abstract

Formasi shale sangat reaktif terhadap lumpur pemboran berbasis air akibat hidrasi mineral lempung yang memicu swelling dan ketidakstabilan lubang bor. Maka dari itu High Performance Water-Based Mud (HPWBM) dirancang untuk memberikan inhibisi setara Oil-Based Mud namun lebih ramah lingkungan. penelitian ini menguji pengaruh penambahan polyamine (1%, 2%, 3% v/v) dalam pengurangan swelling shale. Pengujian dimulai dari Mengukur densitas (Mud Balance), viskositas (Marsh Funnel), rheology lumpur PV, YP, Gel Strenght (Rheometer), banyaknya filtrate dan mud cake (API Filter Press/30 min), HTHP @250, pengujian pH (pH Indicator), pengujian K+, Cl-, MBT & A Perencanaan dan pengujian lumpur dilakukan di PT. Adiguna Cakra Semesta. Hasil uji Swelling dengan menggunakan Liner Swell Meter terhadap 4 sample core yang berbeda yaitu HPWBM-Based Pengembangan 24.3%, HPWBM-Polyamine 1% Pengembangan 16.4%, 2% Pengembangan 14.1%, dan 3% Pengembangan 13.5%. Hasil menunjukan reaksi lumpur HPWBM-Polyamine 3% terhadap sample core (Shale) mampu menahan pengembangan shale atau Menghambat hidrasi air filtrat ke shale cukup baik sebesar 13.5%.
