iOG Production (Hydrocarbon) Accounting Solution

Production accounting helps you monitor business processes for production, transport, sales and revenue of oil and gas. By monitoring every hydrocarbon produced, transported or sold, the value of the oil and gas from different sources can be determined.

Production accounting is also called as Hydrocarbon accounting (HCA) and covers Production, Revenue, Joint Venture accounting, component allocations and Terminal / FPSO / LNG operations as shown in diagram below. Oil and gas production accountants track and analyse production data, calculate revenue and royalties associated with properties owned by oil companies and ensure reporting requirements are met.

Production and operating data is indispensable for reporting to royalty owners, joint venture partners, purchasers, service companies, transporters and various government organizations. With complex contractual agreements to observe, it is commercially critical to have a system which accurately allocates and calculates these values.
