Spudding of Deep Well 707 and planned board changes

Introduction

The Board of Caspian Sunrise is pleased to update shareholders with news that the first of three new deep wells at the Yelemes Deep structure on the BNG Contract Area has been spudded and with planned board changes later in the year.

 

Deep Well 707

The licence at the Yelemes Deep structure was renewed at the end of December 2025 as an appraisal licence with the obligation to drill three deep wells before the end of 2027 to qualify to apply for a 25-year production licence.

Well 707 is to be drilled to a Planned Total Depth of 3,500 meters, targeting the Lower Triassic T1 reservoir.

The well is planned to test a fault-related structural closure. Its principal objectives are to establish the lateral and vertical extent of the Lower Triassic reservoir, refine the position of the oil-water contact, and evaluate the hydrocarbon potential of the overlying Middle Jurassic section.

Planned board changes

With effect from 31 December 2026 and in accordance with the Company's succession plans, Clive Carver, (Chairman) and Seokwoo Shin (Non-executive director) will leave the board.

Further announcements about new board members will be made in due course.
