The Malay Basin is a major sedimentary depocentre located off the east coast of Peninsular Malaysia. Recent exploration has focused on mature shelf areas where geology is well understood. Low-risk, infrastructure-led drilling programmes are prevalent, underpinning high success rates. Average discovery sizes are typically < 10 mmboe. Nearly all discovered gas is sold into the domestic market, where PETRONAS controls a monopoly on the purchase of gas, keeping prices low. Despite this, future oil and gas discoveries can leverage existing infrastructure for low cost development solutions (including ERD and sub-sea tieback) to create value. This Exploration Basin report provides a detailed analysis of exploration performance and future potential, including location maps and details on costs, licensing and fiscal terms. We model prospect and play economics and forecast yet-to-find volume. This report is accompanied by excel downloads which detail costs, volumes and value.
