Accord lead innovation projects to develop scientific concepts and software solutions which meet specific requirements within the oil and gas accounting domain.

Our publications can be found here.

The sections below describe some of Accord’s key innovation projects.

Knowledge Transfer Partnership 1 – CHARM

A Knowledge Transfer Partnership (KTP) is a government initiative to drive productivity and economic growth by supporting businesses to develop and realise potential of new ideas. 

KTP Scotland > Centres > North of Scotland

In our first Knowledge Transfer Partnership (KTP) with Robert Gordon University (RGU), we developed CHARM (Compact Hydrocarbon Allocation Reference Model).  

This is a simple, fast and cost-effective process simulation software package which models hydrocarbon behaviour specifically for hydrocarbon allocation purposes. Developed with RGU’s Smart Data Technology Team, CHARM has been tailored to meet an industry need for cost-effective, usable and practical hydrocarbon modelling software.

More details about CHARM can be found here.

Knowledge Transfer Partnership 2 – Data Reconciliation and Gross Error Detection

In 2019, Accord began a second KTP with RGU.  The focus of this KTP is to develop and implement an innovative Bayesian based data reconciliation and Gross Error Detection (GED) approach for hydrocarbon allocation and attribution using a cloud-based software approach.  The aim is to deliver a product which can be integrated within existing systems and which uses established data reconciliation techniques alongside new analytical methods, to determine measurement quality of complex systems and identify likely issues.

Details of this KTP can be found here.  

Net Zero Transition Centre (NZTC) – CHARM Combustor

In 2021, Accord began work on developing the CHARM product to calculate the flare efficiency and emission factors.  In this project, Accord will deploy a dynamic process simulation model, based on recent research, which will allow Oil and Gas Operators to calculate combustion efficiency and provide a control mechanism to improve the efficiency of their flaring operations and thereby reduce the overall emission rates of CO2 and Methane. 

This project is currently undergoing review to be approved by the Net Zero Transition Centre who work with partners to deploy technology for an affordable net zero energy industry.

Accord and DP Diagnostics have developed a patent pending approach to reduce flow rate measurement uncertainty in differential pressure meters with three pressure tappings.  The approach initially combined spatial redundancy of three differential pressure measurements, their associated flow rates and uncertainties to reduce the overall flow rate uncertainty in comparison to ISO-5167.  Further reduction in flow rate uncertainty has been shown to be possible by applying filtering techniques to take advantage of temporal redundancy in measurements.  While Oculus was initially developed for traditional oil and gas applications, recent research has focused on its use in carbon capture and storage, where orifice meters offer to be a more cost-effective solution compared to USM and Coriolis meters, and when equipped with Oculus can additionally be used to estimate fluid properties.
