OVERVIEW
Abandonment and Site Restoration (“ASR”) or Post Operation Activities are activities for the permanent closure of wells, termination of operation and eliminate the capabilities of Production Facilities and facilities supporting facilities so that they can be re-operated including permanent demolition, as well as carrying out environmental restoration in the WK in Business Activities Upstream Oil and Gas. |
COURSE CONTENT
|
MODULE 1: Regulatory Frameworks, Policy & ASR Strategy
-
- Introduction to the ASR Lifecycle: Understanding asset retirement obligations (ARO) within the upstream oil and gas value chain.
- International Standards & Treaties: Compliance with UNCLOS (UN Convention on the Law of the Sea) and regional maritime conventions.
- National Legal Foundations: Reviewing state-specific policies (e.g., Indonesia’s Permen ESDM 15/2018 and PTK-040, or the EPRA guidelines internationally).
- The Polluter Pays Principle: Evaluating historical versus current Production Sharing Contract (PSC) liabilities.
- Residual Liability Allocation: Managing long-term contractual risks and legal handovers between older and newer field operators.
MODULE 2: Well Plugging & Abandonment (P&A) Engineering
-
- Well Architecture & Integrity Evaluation: Assessing aging casings, downhole corrosion, and structural erosion.
- Subsurface Geological Assessment: Identifying fluid migration paths, formation pressures, and key cross-flow risks.
- Barrier Element Selection: Comparing mechanical bridge plugs against standard cement and advanced alternative materials.
- Rig vs. Rigless P&A Methods: Operational trade-offs, coiled tubing deployment, and new rigless isolation technologies.
-
- Verification and Isolation Protocols: Ensuring permanent structural isolation through strict downhole pressure and pressure-testing criteria.
MODULE 3: Facilities Decommissioning & Infrastructure Removal
-
- Hydrocarbon Flushing & Decontamination: Clearing all toxic, hazardous, and flammable wastes out of processing flowlines.
- Onshore Infrastructure Disassembly: Methods for dismantling gathering stations, pipelines, storage tanks, and terminal facilities.
- Offshore Structure Dismantling: Topside and structural jacket removal strategies (e.g., piece-small, single-lift, or reverse float-over).
- Subsea Infrastructure Engineering: Decommissioning deepwater subsea trees, manifolds, umbilicals, and buried subsea pipelines.
- Heavy-Lift and Logistics Management: Transporting large marine components to coastal offloading hubs safely.
MODULE 4: Environmental Assessment & Site Restoration
-
- Environmental Based Assessment (EBA): Conducting pre-abandonment baselines compared to the region’s Initial Environmental State.
- Soil and Water Bioremediation: Treating oil-impacted zones and decontaminating toxic soil from upstream operations.
- Waste Management & Recycling: Maximizing scrap steel salvage while strictly regulating offshore hazardous waste disposal.
- Ecological Land Restoration: Re-contouring topography and restoring native flora/fauna to closely mimic surrounding ecosystems.
- Onshore Closeout & Long-term Auditing: Securing regulatory approvals, tracking biodiversity indices, and post-restoration monitoring.
MODULE 5: Financial Accounting, Cost Estimation & Contracting
-
- ASR Fund Structuring & Accounting: Accounting for asset retirement obligations (ARO) and joint escrow fund deposits.
- Cost Estimation & Equation Modeling: Building deterministic and probabilistic budgets covering engineering design, permits, transport, and disposal.
- Cost Recovery & Contractual Strategies: Deducting project execution spending via cost recovery lines inside operating contracts.
- Decommissioning Project Campaigns: Lowering operational overhead through resource sharing, multi-well campaigns, and contract structuring.
- Case Study Analysis: Reviewing international execution benchmarks, major cost overruns, and global lessons learned.
