Summary/Abstract
Studies to date have generally shown that individual CO2-EOR offshore projects are uneconomic except under questionable assumptions. The present study is based on an interconnected cluster of nine oilfields in the Central North Sea linked to an onshore CO2 collection hub by a set of existing and new pipelines. Monte Carlo simulation modelling was undertaken of the prospective returns to investments in CO2-EOR in the fields. Relatively high oil prices were employed for the study period (2020-2050) and two contrasting CO2 transfer price scenarios, the first being the Carbon Price Floor (CPF) introduced by the UK Government and the second being relatively low negotiated prices reflecting recent and prospective levels under the EU-ETS. At CPF prices the investment returns were all found to be negative, but at prices averaging £10 per tonne positive returns were generally achieved. The study emphasises the importance of CO2 prices and the taxation system in determining the viability of the investments.

Futuristic least-cost optimisation model of CO2 transportation

Summary/Abstract
The owners of 8 power plants in the UK have announced interest in capturing and sequestering CO2. Using various criteria from the literature twenty fields in the UK Continental Shelf were selected as possible sinks for the captured CO2. Using a linear programming model, the study determined the least-cost transportation network under various constraints on the volumes of CO2 captured from the sources and the injection rates at the sinks. Four scenarios were developed to gauge the sensitivity of the results to these and to the availability of fields for EOR and Permanent Storage. Depending on the scenario, the optimal transportation CAPEX was found to range between £3.5 and £5.2 billion in real terms. With higher minimum injection rates at the fields, accelerating CO2-EOR investments was found to reduce unit transportation CAPEX compared to waiting for their cessation of production dates. On the other hand a combination of the later availability of the CO2-EOR fields plus a lower minimum injection rate yielded the minimum transportation network CAPEX. The modelling also unveiled the problem of CO2 supply overflows in the longer term. The modelling approach has wide applicability beyond the UK.
