The operating context

Managing an oil and gas operation where the standard tools don't fit.

Off-the-shelf ERP products are designed for the assumptions of stable markets: reliable connectivity, single-currency reporting, standard vendor ecosystems and conventional supply chains. Serrona's operating environment in South Sudan matched none of these. Field operations and the Juba office needed to stay synchronised across intermittent connectivity. Financial reporting ran in USD with local currency exposure. Materials procurement spanned international suppliers, regional logistics hubs and local vendors — each with different payment and documentation requirements.

Beyond the environment, oil and gas operations carry specific management requirements that generic ERPs handle poorly: well and field asset tracking, production volumes and lifting management, contractor timesheets for a mixed workforce of permanents and short-contract field hands, and regulatory reporting to the South Sudan Ministry of Petroleum.

Arton built the ERP around Serrona's actual operating model rather than adapting the operating model to fit available software — a distinction that determined the design approach from day one.
