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.
