Outline Introduction Basics of Reservoir Management Topics related to Reservoir Management Reservoir Management Application (Case Studies) Introduction Definitions Why When Who What How Reservoir...? • Reservoir adalah batuan yang porous dan permeable yang berisi hydrocarbon • Porositas adalah persentase pori-pori dalam batuan • Permeabilitas adalah kemampuan batuan mengalirkan fluida • Saturasi adalah persentase fluida dalam pori-pori batuan q = (kA/m) (dP/dL) Reserve • Original Oil In Place (OOIP) adalah jumlah kandungan hidrokarbon yang ada dalam reservoir pada saat awal ditemukan. Diklasifikasikan sebagai OOIP Pasti (Proven), Mungkin (Possible), dan Harapan (Probable) • Recoverable Reserve adalah pengambilan maksimum hidrokarbon ke permukaan, biasa disebut sebagai Cadangan • Recovery Factor (RF) adalah persentase hidrokarbon yang dapat diambil dari reservoir • Withdrawal Rate adalah (persentase) laju produksi hidrokarbon terhadap sisa cadangan • Volumetric • Material Balance • Decline Curve Analysis • Reservoir Simulation Reserve Calculation Menghitung Cadangan • VOLUMETRIC OOIP = 7758 [Ahf (1 – Swi – Sgi)]/Boi [STB] • Material Balance OOIP = Volume sisa + Volume yang diproduksikan • Decline Curve Analysis Q = qi exp (-Dt) • Reservoir Simulation Reservoir Engineer Reservoir Engineer’s Tool Recovery Stages • PRIMERY RECOVERY Pengurasan Tahap Primer adalah pengambilan hidrokarbon dengan cara “biasa” (termasuk penerapan Artificial Lift) • ENHANCED OIL RECOVERY Pengurasan Tahap Lanjut adalah pengambilan hidrokarbon dengan cara menambahkan energi, bahan kimia atau mikrobial ke dalam reservoir dengan tujuan meningkatkan oil recovery Management POAC 5M Synergy Team + BASICS OF RESERVOIR MANAGEMENT Setting Strategy Developing Plan Implementing Reservoir Management Revising Process Monitoring Evaluating Completing Setting Strategy SWOT Analysis, e.g.: Reservoir Characteristics Environment Aspects Technology/Tools Human Resources Targets: Short-Middle-Long Reservoir Knowledge Geology Recovery Mechanisms Rock Properties GOC Kr Oil Water WOC Sw Fluid Properties Fluid Flow Past Performance P GOR Bo Oil Oil Water Water P Time Environment Aspectsa Internal Culture Attitude Capitals External Oil Price Politics Economy (Macro, Micro) Regulations Technology/Tools Geophysics Geology Drilling Reservoir Production (Recovery) Processing (Storage) Transporting Technology/Tools Production Reservoir Geophysics Geology Engineering Engineering Core Portfolio 2D Seismic Economics Description Management Data Acquisition 3D Seismic Thin Section Log Analysis & Management Depositional Well Transient Tomography Models Stimulation Well Analysis Diagenetic Pipeflow VSP Core Analysis Models Simulation Shear Wave Remote Wellbore CT Scan Logging Sensing Simulation (NMR) Maps, Cross Nodal Fluid Section Analysis Analysis Decline Curve X-Ray Analysis Image Material Analysis Balance Waterflooding Streamtube Models Reservoir Simulation Geostattistics EOR Steps of Developing Plan Development and Depletion Strategy Environmental Considerations Data Acquisition and Analyses Geological and Numerical Model Studies Production and Reserves Forecasts Facilities Requirement Economic Optimization Management Approval Development & Depletion Strategy Depend on “Reservoir’s Life Stages” New Discovery Well Spacing Number of Wells Recovery Methods (Scenario) Matured Fields Production Optimization Artificial Lifts Improved Oil Recovery (IOR) Environment Considerations Regulations Resources Ecology etc Data Acquisition and Analysis Plan, Justify, Time, Prioritize Before During Production Production Collect and Analyze Validate/Store Seismic Data Base Well Test Geologic Production Logging Injection Coring Special Fluid Well Test Steps of Developing Plan Development and Depletion Strategy Environmental Considerations Data Acquisition and Analyses Geological and Numerical Model Studies Production and Reserves Forecasts Facilities Requirement Economic Optimization Management Approval IMPLEMENTATION Implementation Synergy Team Approach Contingency Actions Management Support Field Personnel Commitment Periodic Meeting Avoid: Lack of communication Poor knowledge of the projects Delay initiation in Management Process Synergy Team Production Operation Engineers Reservoir Engineers Production Facilities Engineers Reservoir Reservoir Geologists/ Management Management Petrophysicists Operation Engineers Geophysicists Field Operation Group Monitoring Production Data (oil; gas; water) Water/Gas Injection Data Well Test Data (production/injection; pressure) Environment Production Facilities System Evaluation and Revision Comparing the realization and planning Technical and Non-Technical Aspects Revision Is it better than before (technically; economically)?
