Oil India (OIL) and Kellton Tech Solutions (Kellton) have launched a large-scale digital wellhead monitoring system that brings real-time production data from field sites onto a unified platform. The initiative uses the Optima Digital Oilfield Platform (Optima) and follows an implementation contract awarded in December 2024 valued at approximately two point five mn US dollars. The deployment was formally launched under the leadership of OIL's chairman and managing director, and completes a significant phase of the company's collaboration. Kellton brings a global delivery capability with over 2,000 professionals across North America, Europe, the Middle East and Asia to support the programme. Optima provides a scalable digital foundation for upstream operations, enabling AI-driven production analytics, predictive maintenance, intelligent workflow automation and integrated asset lifecycle management. The platform combines edge intelligence with cloud-native architecture to support digital twin environments and centralised operational visibility. These capabilities are intended to accelerate decision-making and operational efficiency across production sites. The programme links real-time data from 77 production wells across 46 plinths to Optima and was delivered within a six-month implementation timeline. The integrated edge-to-cloud monitoring environment is built on 482 field devices, including 390 wireless and wired sensors and gauges, secure telemetry gateways and solar-powered infrastructure. The technical stack incorporates Emerson field instrumentation and AWS cloud infrastructure to underpin production intelligence and remote monitoring capabilities. Kellton reported that the deployment enhances visibility across field operations and provides a future-ready foundation for ongoing optimisation and innovation initiatives at OIL. The company has demonstrated the platform in energy enterprises across multiple countries and leverages a global workforce of 2,000 professionals to support delivery and scale. The initiative is described as a milestone in OIL's digital transformation and as a model for intelligent oilfield operations going forward and to strengthen maintenance foresight across assets.
