ABSTRACT The O&G industry continues to seek increased efficiency and reduced cost through digital technologies and the Internet of Things (loT) that may potentially facilitate more effective data capture, data management, analytics, and hence better decision making. Digital investments seem to be focusing primarily on general production and maintenance opportunities. Many operators manage an abundance of corrosion and integrity related data, but these data may not always be used as effectively as possible to assess equipment health. There is an opportunity, depending on the circumstances, to maximize the value of the data that already exist and to advance technologies that provide opportunities to more efficiently gather data. This paper provides an overview and possible methods for consideration in how to capture the full potential of digital technologies for corrosion and integrity management with a focus on upstream pipelines, considering current industry offerings but also potential new technologies. The importance of developing a holistic, long term digital strategy is discussed, where the strategy targets key value drivers and considers people, business processes and technologies. The paper also provides thoughts about where the corrosion and integrity management community can influence technology development in this space. INTRODUCTION Pipeline operators have to manage a variety of risks while ensuring that they can operate cost effectively. The risks depend on the environment the specific pipelines operate in, both internal and external service condition and other factors like 3 party interaction. The operators also need to consider that these risks change over time. Over the last decades, significant advancements have been made in digital technology and the O&G industry and pipeline operators continue to seek increased efficiency and reduced cost through digital solutions that may potentially facilitate more effective data capture, data management, analytics and better decision making. Even though the focus in digital investments seems to be on general production and maintenance opportunities, like condition based maintenance and production optimization, the pipeline industry has developed in several technology areas and there is an increase in digital integrity management service offerings.

Abstract This paper describes the development and deployment of a customised, on-line well integrity management system that has resulted in a major improvement in the effective and timely identification, diagnosis and remediation of well integrity issues in RasGas operations. The system, which was built in-house on a web portal, is a business-driven, interactive and collaborative solution that integrates well integrity surveillance data (annuli surveys, integrity tests, corrosion log results, etc.) with maintenance schedules, and provides timely reporting of potential or observed integrity problems and harvesting of historical well data. This enables RasGas engineers and operations personnel to make informed and timely decisions on well integrity to ensure continued safe operation and a high level of well reliability and availability. Key features of the system include effective visualisation of safety-critical elements and operating parameters from the field, effective tracking of integrity testing and preventive maintenance activities, use of "surveillance-by-exception" principle under which the system sends out a notification to all key personnel if any integrity-critical parameter on any well falls outside pre-established limits. The paper will illustrate the effectiveness of the system with actual field examples. Planned enhancements such as incorporating well failure models and individual well risk rating system will also be described. While there are a number of packaged well integrity management tools available in the market, the uniqueness of RasGas system lies in its in-house development which has resulted in seamless integration with the existing data telemetry and processing workflows, flexibility in incorporating customised solutions and ease of scalability to accommodate increasing well count. The paper describes the key factors that contributed to the successful development and deployment of the system, including buy-in from all stakeholders, continuous feedback from field personnel and timely familiarisation and training of the end users.

Abstract The communication of data between various operator and service company data stores has long been problematic. Fragile, low bandwidth lines of communication coupled with a lack of standards have left serious efficiency gaps in the movement of data from the acquisition location to decision-making and interpretation centers. Various systems have been developed and deployed to minimize these difficulties; however, all have fallen short of industry requirements. Recent availability of more robust, higher bandwidth lines between locations has led to a new standard of communication called Wellsite Information Transfer Standard Markup Language (WITSML). Using this new technology, data can be acquired and transmitted synchronously or asynchronously among multiple stakeholders with limited effort. The ability to mix and match various data collection vendors and connect these data sources to interpreters and modelers with limited effort is creating new opportunities to improve the success and efficiency of remote operations. This paper reviews four cases that demonstrate the use of WITSML to synchronously transmit real-time data from domestic and international offshore locations to onshore sites. The cases clearly demonstrate that WITSML meets previously neglected industry requirements of durability, flexibility, economy and ease of use in omni-directional data transmission between rig and shore. Introduction The petroleum industry thrives on its ability to acquire, manipulate and share ever-improving types of data. Numerous industry standards have been developed to ease the transfer and manipulation of this data; however, each is limited by the knowledge and technology available at the time the standard was created. Furthermore, the value of using data synchronously with its acquisition is becoming increasingly more evident. Technology advancements in offshore telecommunications have seen the radio replaced by the facsimile, the facsimile by email and now email by synchronous broadband connections over the Internet. Similarly, decision makers want to replace their static reports with secure, synchronous, dynamic information flowing from multiple vendors to multiple assets and stakeholders. Operators have been historically dissatisfied with proprietary data acquisition and transmission solutions that obligate them to a single vendor because a successful operation typically requires components from multiple data-acquisition companies. These demands were the impetus for the American Petroleum Institute to create the wellsite information transfer specification (WITS) standard for moving drilling data between rig and office-based computer systems. The goal was to standardize rig-to-shore data transmission so that various acquisition companies could communicate with each other and the operator in a common language. Like the standards before it, WITS had numerous limitations that prevented it from becoming a perfectly acceptable solution to the aforementioned demands. WITSML is a collaborative effort to update the widely used WITS. Internet standards-driven and hardware and software platform-independent, this new specification for secure, synchronous and asynchronous data transmission has recently emerged from the testing stage into commercial field deployment. Basic WITSML Design WITSML is a standard for sending wellsite information in a standard format between business partners using Internet-compliant rules (i.e. the familiar XML document format and HTTP/S-based delivery protocols). The content of an XML document is defined by XML schemas. A WITSML data object is a logical organization and grouping of the data items associated with the major components and operations involved in drilling a well. For example, the group known as the rig "data object" contains the data item related to the rig such as its owner, type and manufacture.

Compilation of a series of articles published in the Journal of Petroleum Technology between January 2004 and May 2005. Summary In 2002, SPE highlighted the importance of creating technology for oil and gas extraction through the formation of the R&D Advisory Committee. The committee's aim is to foster the continuing development of petroleum engineering technology through collaborations of academia, industry, and government groups worldwide. Included was the introduction of "performance metrics" for this effort and the desire to ensure that the value—financial and otherwise—of R&D to the oil and gas industry receives much greater attention. A major impetus for the committee's activities has been the decline in research activity among major operating companies and the perception that this decline has not only decreased the direct research efforts of these companies but also reduced their participation in collaborative research activities with academia, government laboratories, and private research companies. The need for continued collaborative research efforts is clear, at least from the academic side. For example, in the 2002-03 academic year, industry provided about 42% of the total external funding at the U. of Texas Petroleum and Geosystems Engineering Dept. At the U. of Tulsa, industry funding during the same period accounted for 54% of external research funding. The continuing health of petroleum engineering departments and other research providers throughout the world depends on such support from industry collaborators. The R&D Advisory Committee chose to adddress the current state of industry R&D through a series of articles in JPT that highlight currentR&D activities under way in academia, in government laboratories, and in industry. The articles also attempt to identify the areas of most pressingneed for future research. These JPT articles, published between January 2004 and May 2005, focus on the SPE technical disciplines of Drilling and Completions; Facilities and Construction; Health, Safety, and Environment; Management and Information;Production and Operations; and Reservoir Description and Dynamics, with each article written by recognized research leaders in these fields. The authors were asked to present some recent success stories that show the value of newtechnology development and to predict the R&D needs of the future in their areas. Common Themes A theme common to R&D endeavors in the six disciplines is an emphasis on economic benefit. Many of the successful R&D projects reviewed were relatively short-term, with clearly identifiable economic returns resulting. The longer-term efforts described have less clear definition and higher risk, but with potential economic returns that are substantial enough to be attractive, even in light of the risks. R&D is an astute investment.
