Enhance your prospectivity assessments of frontier basins offshore Sri Lanka with our new broadband 2D seismic surveys. The passive margins of Sri Lanka date to the breakup of Gondwana and include the East Lanka and South Lanka Basins. In the north and west are the failed rift basins of Cauvery and Mannar. Initial investigations of the Mannar Basin suggest potential mature source rocks located in the Mesozoic section, resulting in economically viable volumes of hydrocarbons in the Tertiary. Designed using regional discovery-well information, these 2D surveys optimize imaging of both shallow- and deepwater targets and provide a unique opportunity for early entry into an underexplored region with a proven petroleum system.
Acquired in 2018, simultaneously with gravity and magnetic data, this 13,080-km-long offset seismic data is ideally suited for uncovering deep basement structures. The data was processed and imaged using modern broadband workflows, including state-of-the-art noise attenuation and demultiple techniques, adaptive deghosting, and tomography with Kirchhoff migration.
Analysis of the data clearly identifies an extrusive layer of flood volcanics at the reservoir level that includes proven gas reserves. The data was also used to understand prerift basement geometries linked to those seen in eastern Africa. Another use for the data has been initial AVO analysis to help understand potential plays in the Eastern Province.
Prestack time migration (PSTM) and prestack depth migration (PSDM) data and AVO analysis are now available to help you
