EXPERTISE / ALLOCATION
Delivering Confidence
in Allocation
Robust allocation engineering, efficient processes and rigorous analysis are vital to the success of and stakeholder confidence in oil and gas systems — from reservoir engineering to commercial allocation and environmental, regulatory and partner reporting.
In principle, hydrocarbon allocation appears a relatively simple concept, but in practice it requires detailed knowledge of the physical infrastructure, process engineering, measurement and commercial context. An analysis of the uncertainties and how they propagate is key to determining optimal allocation regimes. Development of accurate and equitable allocation systems mitigates against financial and reputational damage.
Accord’s skilled and experienced team have an in-depth and practical understanding of allocation regimes around the world. We support clients on three broad fronts:
Strategic — defining approach, cost-benefit analysis, feasibility studies, stakeholder engagement, devising allocation philosophies.
Technical — detailed allocation equations, uncertainty analysis, mathematical rigour, developing technical schedules, impact analysis and system design.
Advisory — auditing existing allocation regimes, professional recommendations, acting as an expert for dispute resolution, managing projects, advising clients on next steps.
Allocation Engineering, Delivered in Detail
Independent & Impartial
Accord are completely independent and aren’t a subsidiary of any other enterprise in the energy sector — meaning our work, advice and recommendations are always impartial and unaffected by any obligation or prior preference.
Assurance
As well as developing and delivering novel allocation solutions, Accord can offer clients a detailed audit of existing systems and undertake analysis to identify anomalies, project the impact of any proposed changes and determine exposure to risk.
The Right Approach
Our team has significant experience of working with clients of various scales and across a range of hydrocarbon accounting systems. We recognise that each client has unique circumstances and we deliver our work on an individual basis — the right approach for each client and scenario.
Reducing Methane Emissions
After carbon dioxide, methane is the most important greenhouse gas contributing to climate change. Although it has a shorter atmospheric life than carbon dioxide, it is over 80 times more potent so reduction in methane emissions has a key part to play in climate change mitigation. With an increasing focus on methane, operators are seeking to manage their flare activity to understand and reduce their methane emissions.
Accurate calculation of the combustion efficiency is essential to understanding the greenhouse gas emissions from flare systems. Backed by the Net Zero Technology Centre, Accord has developed a tool to calculate online combustion efficiency — Combustor. This will allow operators to calculate emissions accurately and to provide online feedback to control systems to reduce overall methane emissions.
Carbon Capture
Carbon Capture and Storage (CCS) projects — in which CO2 is gathered from various sources, compressed and exported via pipelines into subsea reservoirs for storage — can benefit from Accord's expertise, to overcome such issues as:
- Non-ideal behaviour of CO2 at high pressures
- Impact of impurities from different sources and industries
- Equitable allocation of high compression power consumption
- The “Long Pipeline Effect”
- Calculation of uncertainties
