The Horizon South block is operated by Stratos Energy Ltd. (40% interest), with co-investments from Novara Petrochem (30%) and Helix GeoVentures (30%). The license was awarded under a modernized shared-risk production framework on August 22, 2019, with commercial operations deemed effective from January 26, 2020. Initial exploration drilling in this block commenced with the deployment of the Aurora-1 well, operated by TerraNova Drilling Co., which was spudded on May 21, 2002, in a water depth of 2,436 feet. The well was drilled to a total measured depth of 13,441 feet (with a true vertical depth of 13,100 feet below sea surface), and operations concluded by June 7, 2002. Earlier hydrocarbon indications in the same structural corridor were confirmed by the successful drilling of the Epsilon-4 well in 2001, operated by a former license holder, BlueArc Resources. The Aurora-1 and Epsilon-4 wells are located on the southwestern flank of the main geological structure, separated by a subsurface saddle feature. 1.2 Field Development Strategy The proposed development plan involves a subsea tieback of the new field to pre- existing offshore infrastructure. This concept takes advantage of available processing and transportation capacity in maturing production assets projected to enter late-life phases. The tie-in site is favorably located near the Central Nexus Facility, minimizing the need for extensive retrofitting and enabling a streamlined integration into the existing production system. 2.0 Regulatory Framework, Standards, and Compliance Requirements The CONTRACTOR shall adhere to all applicable regional and global regulatory frameworks governing marine operations, offshore development, and industrial safety.

It shall neither be shown to Third Parties not used for purposes other than those for which it has been sent. granularity=word contentanalysis={punctuationbreaks=false dehyphenate=false} layoutanalysis={tabledetect=0 layoutdetect=0} This chapter outlines the equipment supply scope for PROJECT ALPINE, consistent with the design principles established in the Basis of Design (reference [17]). PRIME ENERGY emphasizes product standardization to facilitate potential expansion to additional fields within the Horizon South block by utilizing equipment built on the same fundamental design. Confirmation of this potential will be made once further details for these optional developments are finalized. Certain specifications detailed below presuppose particular equipment configurations which may evolve as the design matures. Finalized scope and quantities will be determined at the Contract Award stage between the Contractor and PRIME ENERGY. It is the Contractor’s obligation, subject to PRIME ENERGY’s approval, to update this scope as designs develop to guarantee delivery of the required equipment in accurate quantities, fulfilling all project objectives and ensuring system operability. The Contractor must identify all equipment and tooling necessary to meet contractual requirements—including compliance with the External Interface and Responsibilities Matrix (reference [4])—prior to Contract Award, incorporating them into both Scope of Supply and Scope of Work, and including them in the commercial proposal. Any components omitted from the Master Equipment List but required for system functionality shall be supplied at the Contractor’s cost. Modifications to scope, such as additions or reductions driven by PRIME ENERGY instructions or emergent needs, will be managed via Variation Orders. PRIME ENERGY will not accept Variation Orders arising from the Contractor’s failure to identify required items during initial planning, considering such omissions a contractual breach. Additionally, the Contractor is responsible for supplying all proprietary special tools essential for successful completion of the works that are unique to the Contractor’s technology and unavailable from third parties. The Contractor shall also include in the scope sufficient fabrication spares, particularly for long lead-time items, to prevent project delays due to manufacturing issues. 10.2 Equipment Qualification Criteria The Contractor shall propose field-proven equipment wherever possible.
