Implementing a Risk-Based Integrity Management System (CIMS) in Upstream Oil & Gas Operations
(2026) Nicholas Piet; Rafael Valecillos Alen; Austin Armstrong; Carlos Johnny Portilla Salazar; Benjamin Manning; Enric Truñó Cunill
Abstract Repsol has recently implemented an integrity management system for static equipment, including vessels, piping, tanks, PSVs and pipelines, featuring a risk-based inspection (RBI) module. This software, known as the Computerized Integrity Management System (CIMS), has significantly enhanced operational oversight across multiple upstream assets. The CIMS implementation involved deploying a specialized software platform focused on four core areas: (1) inspection data management, (2) anomaly management, (3) RBI assessments, and (4) preventive and corrective maintenance planning. This transition marked a major shift in the Company's integrity practices, requiring cross-disciplinary collaboration and strong management support to ensure resource alignment and successful adoption. By centralizing integrity data and enabling in-house inspection capabilities, CIMS has improved visibility, ownership, and responsiveness. The shift from a time-based to a risk-based inspection strategy has allowed the Company to prioritize resources toward higher-risk equipment, optimizing inspection intervals and enhancing safety and reliability. This paper will present the implementation journey, highlight key challenges and lessons learned, and outline future plans for continuous improvement.
Review of Internal Corrosion Mechanisms in an Onshore Production Pipeline: a Case Study from the Eagle Ford Basin
(2026) Mónica Fernández; Vanessa Ortiz; Chris Jeske; Carlos Johnny Portilla Salazar
Abstract This paper presents a comprehensive review of internal corrosion mechanisms observed in an 8-inch API 5L X52M onshore production line located in the Eagle Ford Basin. The pipeline, which transports multiphase fluids from a three well pad, exhibited signs of accelerated internal corrosion within the first year of operation. The review integrates metallurgical analysis, microbial DNA sequencing, and operational data to evaluate the contributing factors. Evidence of microbiologically influenced corrosion (MIC) was confirmed through DNA analysis, revealing the presence of sulfate-reducing and iron-oxidizing bacteria which could have been sourced from stagnant hydrotest water or the reservoir. Additionally, the presence of CO2 in the gas phase was identified as a contributor to the corrosion environment. Metallurgical examination revealed characteristic MIC pitting morphologies, while scale composition and flow conditions supported the potential for CO2 corrosion. This case study highlights the importance of proactive corrosion management strategies in new pipeline systems, including proper hydrotest water handling, early implementation of chemical treatment programs, and continuous monitoring. The findings provide valuable insights for improving internal corrosion control in similar onshore production environments.
