Hydrocarbon accounting is a term used to describe
how ownership of gas and oil is determined and tracked from the point of
production to the point of sale. It is sometimes known as Hydrocarbon Value
Realisation, Product Measurement and Allocation or Production Management
and Reporting. Whatever term is used, it generally encompasses several business
processes that are usually defined in contracts or operating agreements.
On-line metering and laboratory analysis generate measurements that, along
with commercial data, are the inputs to allocation. Computers programmed
with the allocation rules use this input data to determine production ownership
and the output is communicated through reports.
