Background of the challenge

PETRONAS is seeking for an integrated technology solutions in terms of simulation or forward modelling results (short term) and new innovative measurement/hardware system (long term) that can measure and quantify CO₂ at downhole in-situ condition in virgin, producing, and depleted reservoirs, with a focus on potential CO₂ re-injection and storage. The solutions can be derived from the existing technology owned by the vendor or can be new and innovative solutions uniquely adopted and patented by the vendor.

Request for proposal description

In fulfilling such expectation, the proposed technology solution should meet the following requirements:

Scope A: Modelling (to be assessed during challenge period)
