AREA OFF-1, Uruguay: commencement of 3D seismic acquisition

 

Sintana Energy Inc. (TSXV: SEI, AIM: SEI, OTCQX: SEUSF), the Atlantic- margin
focused oil and gas company, is pleased to announce that the planned 3D
seismic acquisition campaign on AREA OFF-1, offshore Uruguay, has commenced.

The AREA OFF-1 survey is being carried out by the contractor Viridien, using
the BGP Prospector vessel, and will cover a total of approximately 4,300
km(2). Acquisition fieldwork will take place over two seasons: February-April
2026 and November 2026-April 2027, with most acquisition relevant to the key
prospects on AREA OFF-1 expected to be completed in the first season.
Fast-track results from seismic acquired in the first season are expected in
Q4 2026, with full PSDM results from the first season expected in Q2 2027.

Sintana Energy holds a 40% non-operated interest in the AREA OFF-1 block,
following the farm-out in 2025 of a 60% operating interest to an affiliate of
Chevron Corporation ("Chevron"), and is carried for the total anticipated cost
of the 3D seismic acquisition program.

It is noted that commencement of seismic acquisition follows rejection by
courts in Uruguay of several attempted interventions by activist groups,
demonstrating the depth of the upfront preparatory work for the campaign, and
the robustness of Uruguay's environmental consultation and permitting process.
Sintana Energy remains committed to all operations with which it is associated
being in compliance with the highest health, safety, and environmental
standards.

Robert Bose, Chief Executive Officer of Sintana Energy, commented: "We are
excited to see activity on AREA OFF-1 beginning so soon after completion of
our acquisition of Challenger Energy in December 2025. 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. We look forward to providing
further updates on progress over the coming quarters."
