Otto Energy has begun a 3D seismic data acquisition programme in Service Contract 69 in the Visayan Basin of the Philippines.

The company plans to acquire about 210km² of 3D seismic data and has contracted the seismic vessel BGP Explorer, operated by Exploiter, to record the data.

Service Contract 69 covers an area of 5,280km². Previously acquired data has revealed two sizeable reef structures, Lampos and Lampos South, immediately adjacent to the Calamangan Trough, which has been modelled to generate oil and gas.

The company said that the current success case estimates of oil initially in place in the combined structures range between 22 million barrels and 713 million barrels, with a mean in place volume of 290 million barrels.
