Cairn Implements Smart Well Integrity and Flow Assurance Management System - 1

CASE STUDY Project Summary Organization Vedanta Limited – Cairn Oil and Gas Solution Utilities and Industrial Asset Performance Location Rajasthan, Andhara Pradesh, and Gujarat, India Project Objectives • To develop a smart well integrity and flow assurance management system that automates manual well monitoring and corrective action processes. • To establish a connected digital environment to integrate disparate data and streamline workflows. Products Used AssetWise® Fast Facts • Cairn operates more than 850 oil and gas wells in India that are aging and harbor risk factors affecting well performance. • The company established a connected data environment and implemented a web-based smart well integrity and flow assurance management system. • AssetWise digitalized and automated monitoring and management of Cairn’s entire well stock. ROI • Using AssetWise, Cairn generated a comprehensive central well database that optimized preventive maintenance and corrective action, and increasing productive well time by 10%. • Automating cumulative costperformance plots to evaluate cost benefits improved well productivity by eliminating ineffective operations. • Leveraging AssetWise reduced the potential for uncontrolled fluid release and improved flow assurance management, saving around $1.2 million per year. Cairn Implements Smart Well Integrity and Flow Assurance Management System Bentley’s AssetWise Provides a Connected Data Environment to Streamline Asset Monitoring and Data Analysis Committed to Operational Excellence Approximately 35% of global well inventory suffers from well integrity issues related to corrosion, erosion, and poor-quality cement behind the casing adversely affecting the down-hole well completions and surface pipelines. This situation results in flow assurance issues, asset failure, and subsequent downtime that costs millions of dollars. In addition, oil and gas companies must mitigate risks and safeguard against uncontrolled release of hydrocarbons to protect the environment. As a result, well integrity and flow assurance management have become critical to oil and gas operations. To monitor and control stimulation chemical usage, reduce tubular and pipe corrosion, improve flow assurance, and optimize well integrity, the industry requires continuous visibility into asset reliability, well performance, cost, and environmental impact. Cairn Oil and Gas, Vedanta Limited is the largest privatesector crude oil producer in India. It operates over 850 wells in the Barmer, Ravva, and Cambay areas. With time, well productivity was affected by wax, scaling, corrosion, and increase annuli pressure issues. As manual, errorprone processes fail to provide optimal insight into well integrity management, Cairn explored ways to automate and streamline workflows, and integrate disparate data. The organization sought to implement a smart well integrity and flow assurance management system (SWIM) to efficiently manage associated risks, optimize cost and well performance, and limit environmental impact. “To ensure that the wells are operating optimally, it is very critical that various parameters affecting the performance of the wells are monitored robustly, hence the need for a smart well integrity and flow assurance management system,” said Utkarsh Vijayvargia, senior petroleum engineer at Cairn. A Connected Digital Solution Well integrity and flow assurance management involve a multidiscipline approach, requiring engineers to interact on a regular basis to assess the status of well barriers and safe operating envelopes, as well as manage risks associated with maintaining flow. The sheer number of associated risks Fig.1 – Each well can be monitored to analyze each component’s performance and alert engineers to any possible issues via notifications. Fig. 2 – In order to maintain flow, Cairn monitors cost benefit analysis of individual stimulation treatments of all wells to identify underperforming assets. usually entails numerous stakeholders, voluminous data, and multiple interfaces. With data dispersed among various interfaces and disparate sources, Cairn faced a lack of data visibility and accuracy, which are crucial for decision-making. To implement its SWIM, Cairn relied on Bentley’s AssetWise to establish a connected data environment. The single platform streamlined workflows and converted all processes to a digital format. The interoperability of AssetWise provided a digital solution that interfaced with Cairn’s internal, webbased portal and integrated data from different sources within Cairn. Working in a connected data environment facilitates real-time data accessibility, allowing users to visualize data from wells and run individual queries to produce specified results, including summary data aggregated through the business up to the top level of th
