REQUEST FOR EXPRESSION OF INTEREST FOR KINGFISHER DEVELOPMENT AREA 2D TEST LINE & 3D SEISMIC DATA ACQUISITION AND PROCESSING (RFP-CUL-LD-00855)

CNOOC invites Expression of Interest (EOI) from Professional Competent Companies for provision of Services of Kingfisher Development Area 2D Test Line & 3D Seismic Data Acquisition and Processing.

The project objective:

The overarching objective of this seismic programme is to acquire and process high-quality fully imaged 3D seismic data that resolves the subsurface imaging challenges identified in the licence area. Specifically, the low-quality zones associated with the lake-land transition and their low underlying root causes. The programme follows a phased, decision-driven approach to ensure that the commitment to full 3D acquisition and depth imaging is technically justified, while maintaining flexibility to bypass the test phase when appropriate.

Scope of Work

Package 1 (Exhibit A) - 2D Test Line Acquisition and Evaluation
The Contractor shall acquire, process, and rigorously evaluate one or more 2D test lines with the dual purpose of (a) optimizing the acquisition parameters and (b) judging whether the optimized (present) acquisition parameters deliver a measurable improvement in data quality over existing legacy data, particularly within the problematic lake-land transition zone. The evaluation follows a predefined decision-tree methodology, scoring basic data quality (30 points) and the uplift achieved through dedicated acquisition and processing improvements, as well as interpretative gains in structure, resolution and reservoir characterization (70 points).

Package 2 (Exhibit B) – Full 3D Seismic Acquisition and Processing:
The Contractor shall execute the full 3D seismic survey using the optimized acquisition parameters established from the Package 1. 2D test line evaluation, and to deliver a fully processed 3D volume including Pre-Stack Time Migration (PSTM) and PreStack Depth Migration (PSDM). The final dataset must provide the imaging uplift required to support development planning and reservoir management objectives, effectively overcoming the previously identified low quality zones associated with the lake-land transition. By applying the validated parameters at full scale, this phase ensures that the acquisition and depth imaging programme delivers a technically robust and cost-effective result.

CNOOC shall have the right to select, at its discretion, Work Package 1, Work Package 2, or both Work Packages.

Interested bidders shall submit, via the Company COIRID system, documents relating to the minimum requirements outlined below. (Note: Additional supporting or miscellaneous information may be provided as necessary)
