This paper aims to develop a practical method to evaluate operational performance of workover rigs and present an approach to measure the overall equipment effectiveness (OEE) based on results of the evaluation method.

The area of this study focuses on workover rigs processes in the oilfield and investigates the impact of workover activities on the production at the Sarir Oilfield in Libya. The loss of time from workover procedures and electrical submersible pumps ESP installation and pulling, which affect oil well production, should be eliminated in order to reduce the cost. Several example calculations of workover operation efficiency involving actual workover operational data are presented. The method of evaluation of workover process has been developing which were the bases of OEE calculation.

The measure was developed to help support continuing efforts around process improvements and cost leadership at Oilfields. The results on the empirical findings are introducing OEE for the workover activities which will be used as a valuable indicator for workover activities improvement.

The result of this research makes it possible to represent the OEE as a benchmark that will be used to compare the performance of workover process.

This paper presents a successful and effective evaluation of OEE which will provide a useful observer to set of operational improvement areas and how such activities could be organised and managed more effectively.

The offshore supply vessel (OSV) industry is critical to offshore oil and gas operations around the world and contributes to the economic and ecological impacts experienced by the local communities supporting the offshore oil and gas industries. The OSV industry has not been studied significantly and the economic and ecological impacts to local communities is generally unknown. This paper aims to address these issues.

In this paper, the authors review the activities and logistical requirements involved in offshore exploration and development with special attention paid to workflows and the manner in which service vessels are utilized in the Gulf of Mexico. The authors estimate the OSV needs per stage of activity for offshore operations based on data collected from company planning documents, fleet utilization data from oil and gas companies and service providers, interviews and surveys. The statistical data is synthesized and reconciled and despite large variances the data sources are in reasonable agreement. Empirical data on circuit factors are also provided. The applications and limitations of the analyses are discussed.

In the US GOM, a large variety of marine vessels transport goods and provide services to exploration, development and production activity. OSVs provide a vital link between offshore E&P activities and shore‐based facilities. Offshore oil and gas operations cannot function without them and their utilization and spatial distribution provide a way of understanding the impacts of the offshore oil and gas industry on coastal communities.

This is the first empirical analysis of any offshore service vessel industry. The data presented here can be used to predict the environmental, economic, public health, and infrastructural consequences of alternative offshore development policies.

The purpose of this paper is to know what scientific literature presents about the theme evaluation of seaport performance, thus enabling the construction of knowledge in the researchers and the identification of gaps in the research that will lead to advances in the area from the identification of the characteristics of a portfolio of relevant international publications.

From the basic philosophical (constructivism), of the kind strategy (research-action) and the method used for the accomplishment of such strategy (structured process knowledge development process – constructivist (ProKnow-C)) the current research has a qualitative approach.

From the analysis of the bibliographic portfolio composed of 23 articles, the main results were: focus of the evaluation of seaport performance is on operational and tactical efficiency rather than on strategic and global performance; the majority of the studies does not relate to the reality experienced by seaport managers due to the limited interaction with these managers, evidencing a distance of the researchers from the object of their research; and performance evaluation was barely used/explored as a tool to support management, only for the sake of evaluation itself.

The search occurred in the databases Web of Science, Scopus, Proquest, Ebsco, Sciece Direct and Wiley.

The identification of gaps that might promote advances in this field of knowledge, once the seaport segment is not exploring the potential that performance evaluation can offer and is already available in literature.

Overall equipment effectiveness (OEE) is a metric for estimating equipment effectiveness of the industrial systems. The purpose of this paper is to identify maintenance improvement potentials using an OEE assessment within the croissant production line.

The present work is carried out by analyzing the failure and repair data of the line. The failure data cover a period of 15 months. During this period the croissant production line usually operates over the entire day (24 h per day) in three 8-h shifts per day, and pauses at the weekends. Descriptive statistics of the failure and repair data for the line based on scheduled and unscheduled interruptions were carried. Moreover, the actual availability (A), performance efficiency (PE) and quality rate (Q) measures, together with the complete OEE for each working day for the croissant production line, were shown.

The main objectives are to understand the operation management of the croissant production line, and to measure the OEE characteristics in precise quantitative terms. OEE analysis can help the company to identify the primary problems concerning the A, PE and Q and acts immediately.

This paper presents a successful evaluation of OEE which will provide a useful guide to aspects of the production process, which identifies the critical points of the line that require further improvement through effective maintenance strategy (i.e. total productive maintenance). Moreover, the analysis provides a useful perspective and helps managers and engineers make better decisions on how to improve manufacturing productivity and quality.

Describes flowline problems inherent in the land and swamp fields. Non‐destructive testing ‐ general visual inspection and ultrasonic thickness survey based on the nominal diameter sizes, age category and location of flowlines ‐ was carried out. The readings obtained were used to calculate the percentage weight loss of pipe per metre and deduce the flowline sections that need to be replaced to avoid rupture of the steel pipe or fitting in service, using residual life estimates. The reduction of the wall thickness of the pipes/ fittings is caused by a combination of corrosion initiated by physical deformation anomalies and the presence of corrosive media along the flowline tracks (inside and outside the pipes). Offers new measures to help the company mitigate the various flowline problems.

Overall equipment effectiveness (OEE) provides a quantitative metric based on the elements availability, performance and quality for measuring the performance effectiveness of individual equipment or entire processes. Although these elements are important, other performance factors such as the efficient use of raw materials and the production environment (e.g. production system, logistics, labour, etc.) in which the equipment or process operates may also have a significant contribution to process performance. The purpose of this paper is to present an alternative measure derived from OEE, overall resource effectiveness (ORE), which considers these factors.

The paper reviews the OEE’s background and explores its limitations. Then, it shows the conceptual and mathematical development of the ORE measure and the formulas used for its calculation. Empirical and simulation-based investigations and applications of ORE are carried out through two cases study for its validation.

The results derived from both the empirical and simulation-based investigations demonstrate that OEE may not be an appropriate measure for some specific processes and that ORE may offer a more complete perspective on and information of key performance indicators.

ORE can provide production managers with more complete information concerning the performance of their processes. This will allow them to take better decisions regarding the management and actions needed to improve their processes.

This paper presents a novel and alterative approach to measure the performance of manufacturing equipment and processes.

A systematic literature review is performed to reveal the state-of-the-art in the implementation of lean principles in the petroleum industry. This paper aims to generate a conceptual framework and reveal research gaps with respect to lean concept application in the petroleum industry.

After formulating research questions, the search strategy is generated, followed by data extraction, literature review and synthesis of the results. The search covers any studies in peer-reviewed scientific journals and conference proceedings in the period 1990-2017 that discuss the implementation of the lean concept in the petroleum industry.

The lean concept has been used to improve operational and technical aspects, contractor/supplier relationships, team organization and project management practice in the petroleum industry. Based on the literature review, a conceptual framework is generated comprising four main elements: leadership and commitment from management, employee involvement, cooperation and trust with contractors/suppliers and lean project management. These elements are the pillars that are founded on lean philosophy and principles to support technical/operational improvement in the organization. The types of literature identified indicate that the subject of the study is still immature.

This study focuses only on the upstream sector of the petroleum industry, which restricts the generalizability of the results to midstream and downstream businesses.

This paper provides knowledge and information regarding the current state of lean implementation in the petroleum industry. The developed conceptual framework provides general guidance for practitioners regarding lean implementation in the petroleum industry, and is also expected to support research on theory building.

Few studies have discussed the application of the lean concept in the petroleum industry. This paper contributes a platform for researchers and practitioners to comprehend how the lean concept has been applied in the petroleum industry, and provides a foundation for further studies on lean implementation in the petroleum industry.

The robust appraisal of exploration drilling concepts is essential for establishing the economic viability of a prospective recovery field. This study evaluates the different concept selection methods that were considered for drilling operations at the Trym field in Norway. The construction of drilling rigs is a capital-intensive process, and it involves high levels of economic risk. These risks can be broadly categorised as aleatoric (i.e. those related to chance) and epistemic (i.e. those related to knowledge). Evaluating risks in the investment appraisal process tends to be a complicated process. Project risks are evaluated using Monte Carlo simulation (MCS) and are based on the fuzzy analytic hierarchy process (AHP). MCS provides a useful means of evaluating variabilities (i.e. aleatoric risks) in oil drilling operations. However, many of the economic risks in oil drilling processes are unanticipated, and, in some cases, are not readily expressible in quantitative values. The fuzzy AHP is therefore used to appraise the qualitatively defined indirect revenues comprising risks that affect future flexibilities, schedule certainty and health and safety performance. Both the Monte Carlo technique and the fuzzy AHP technique found that a cumulative revenue variation of up to 30% is possible in any of the considered drilling options. The fuzzy AHP technique estimates that the chances of profitability being less than NOK 1 billion over a five-year period is 0.5%, while the Monte Carlo technique estimates suggest a more conservative proportion of 10%. Overall, the fuzzy AHP technique is easy to use and flexible, and it demonstrates increased robustness and improved predictability.

On May 27, 2020, a blowout occurred in Well No. 5 at Baghjan (Assam); the well, owned by Oil India Ltd., caught fire on June 9, 2020. For almost five and a half months, the company tried to douse the 200-foot high flame but failed to do so. Finally, on Day 173, Oil India Ltd succeeded in capping the well. Biswajit Roy, Director (Human Resources and Business Development), was tasked with investigating the nature and cause of the crisis. Roy pondered on the nature of the crisis: Had it been purely technical or stakeholder-induced? What had led to the chaotic condition? Could things have been done differently?

The purpose of this study is to define and develop a new technological development path for latecomer firms in developing countries.

An analytical framework for development based on the technological capability (TC) dimensions is developed and examined in the drilling sector. Since the process of TC accumulation is dynamic, the case study approach is the best method for an exploratory theory-building study. Through a comparative case study of two Iranian drilling contractors, a new path for the technological development of latecomer oil service companies is proposed.

The study of two cases indicates that despite having similar scope and levels of TC, one of them demonstrated superior technical performance. To address this difference, the concept of operational efficiency is introduced which is considered the outcome of increasing the depth of TC.

Although upgrading the level of technological and innovation capability is an important path for technological development, latecomers that suffer from various disadvantages can perform their routine activities with superior performance and develop through their basic operational/production capabilities. Also, specialized indicators designed for assessing the level and depth of TC in the drilling industry have important insights for evaluating the technological and competitive position of oil service companies.

To the best of the author’s knowledge, this study takes the first step in defining and elaborating on the concept of depth of TC as a development path for latecomers. It also introduced a novel approach to the global operational/production efficiency frontier as a target for their catch-up.
