Sintana Energy Inc (TSX-V:SEI, OTCQB:SEUSF, FRA:3ZX1, AIM:SEI) has kicked off a large-scale 3D seismic programme on its AREA OFF-1 licence offshore Uruguay, marking the start of a major data-gathering push on the Atlantic margin block where a Chevron affiliate is operator.
The company said contractor Viridien has mobilised the BGP Prospector vessel for a survey covering around 4,300 square kilometres.
Acquisition is scheduled across two seasons - February to May 2026 and November 2026 to April 2027 - with most work over the block’s key prospects expected to be completed during the first season.
On timing, Sintana said fast-track results from seismic acquired in the first season are expected in the fourth quarter of 2026, with full pre-stack depth migration results from that season targeted for the second quarter of 2027.
"We are excited to see activity on AREA OFF-1 beginning so soon after completion of our acquisition of Challenger Energy in December," said chief executive Robert Bose.
"3D seismic acquisition is a key next step in defining the potential of Uruguay's offshore embedded within our Transatlantic portfolio, and which is underpinned by a relationship with Chevron that spans the conjugate margins.
On timing, Sintana said fast-track results from seismic acquired in the first season are expected in the fourth quarter of 2026, with full pre-stack depth migration results from that season targeted for the second quarter of 2027.
"We look forward to providing further updates on progress over the coming quarters."
Sintana holds a 40% non-operated interest in AREA OFF-1 and, it is carried for the total cost of the 3D seismic acquisition programme following the farm-out of a 60% operating interest to an affiliate of Chevron.
