Run-life is a concept used in the oil and gas industry to express time to failure for running equipment. When estimating this as part of reliability engineering activities, different metrics and time periods are considered. One metric is the traditional ‘mean time to failure’ (MTTF), but alternatives such as ‘average run-time’ or ‘average run-life’ can also be considered. For calculating these metrics, different time periods can be used. For example, when estimating the MTTF of well completion equipment, operating times or running times are normally used. However, the periods can also include idle time, where the item is technically available, but associated parts of the production facility might not be. For consistency across the industry, on how to interpret the metrics and what to include in calculating them when performing estimations, ISO 14224 (2016) and IEC 60050-192 (2015) in tandem provide guidance to ensure quality in reliability data collection and analysis. While MTTF is defined and a theoretical basis is given, guidance on when to use the different timelines for the estimation is sparse. Neither ‘run-time’ nor ‘run-life’ is explicitly defined in these standards. They provide no guidance on how to interpret and use the metrics ‘average run-time’ and ‘average run-life’, despite these sometimes replacing the MTTF in reliability analyses. In this article, we discuss the variation in metrics and associated timeline definitions. A main purpose is to identify improvement potentials in the international standards and suggest how to achieve appropriate guidance for consistent interpretation and use of time-to-failure metrics in the oil and gas industry. An additional purpose is to clarify whether all these metrics are really needed. There is particularly confusion around ‘run-time’, which some interpret as a reliability metric and some as an item’s cumulative running time. One suggestion is that the standards focus more on ‘running time’, by adding a formal definition, and clarify how it compares with operating time and run-time, and when to use it. We also suggest introducing ‘running time to failure’ and ‘operating time to failure’, which would be consistent with existing terminology, while clarifying the timeline being referred to. We use examples from well drilling and completion systems, to show the reliability implications for modeling and calculations.

Progressive Cavity Pumps (PCPs), if properly sized, can greatly improve a well's deliverability and run-life. As a result, PCP sizing for a large number of wells can be instrumental in a production optimization program. This paper presents a quick look methodology adopted in the Bhagyam field to better understand PCP system performance and to accurately predict pump deliverability under a wide range of downhole conditions for more than a hundred wells. Using nodal analysis, this paper presents the procedure used to select optimum pump size and well fluid rates from well inflow and outflow performance. The paper also presents a correction factor for the effect of viscosity on pump performance and uses the corrected pump performance curves to model the expected liquid rate from a well. The solutions obtained with the analyses have been validated against actual Bhagyam well test data and have proved to be fairly consistent. This procedure has not only been a useful tool for pump selection and performance monitoring but has also made a significant business impact in terms of incremental oil gain.The methodology quickly provides reasonably accurate solutions for pump selection and allows evaluation of real time pump parameters to optimize PCP under varying field conditions.

This paper summarizes the completion designs and operational challenges of successful well completions in more than 400 wells in the Rajasthan onshore block of Northwest India. The Rajasthan onshore block has three core fields, with a total 37 oil and gas discoveries. These wells were completed in over three and a half years without compromising aspects of health, safety, or the environment. During the campaign, a commendable feat of zero HSE incidents was observed. These wells are broadly categorized as development and exploration wells and include a variety of both open- and cased-hole well completions. The completion systems are wide-ranging, varying from monobore conventional completions to open-hole, sand-control applications. The scope of work and challenging parameters include highly deviated open-hole and cased-hole sections, along with complex workovers. A wide range of products and services were designed to maximize well production. The completion design included a variety of packers, flow-control devices, intervention solutions, and other relevant completion tools. There were various operational, health, safety, environmental, logistical, and manufacturing-related challenges that were overcome to drill and complete the wells. The purpose of this paper is to provide insight into the well types, completion designs, and to discuss the associated challenges. The technology and practices established from these successful operations have become the standard operating procedures for completion jobs. This paper will take the reader through the evolution of well-completions technology, from the early days, when perceived risk was both hindered and was the spark for innovation, to the present time, when this technology is routinely used to meet production and reservoir development goals.
