The start of the new millennium will see companies in the oil and gas industry faced with a dual challenge. Not only will they have to undertake exploration in more demanding terrain and environments, but they also face far more competition in what they previously regarded as their traditional marketplace. The goal of meeting both shareholder and customer needs, while simultaneously attempting to increase market share by becoming more competitive, will be paramount if this success is to be achieved. While a number of strategies have been developed over the last decade in an attempt to achieve and balance these financial goals, the control and reduction of costs play a significant part in all such ‘cost effective’ programs. Past approaches have targeted the organisational structure, internal processes and strategic advantage through acquisitions, mergers and downsizing. However, any gains realised by such programs must be continuously improved upon by implementing innovative approaches to future reductions and controlling costs. Some companies have shifted the focus from internal cost scrutiny to influencing and ultimately controlling external factors of cost. The supply chain offers a tremendous opportunity to drive out costs, one such approach being to partner with the best suppliers of key components to shorten delivery times while minimizing life cycle costs. It is therefore paramount that one distinguishes between those who are simply suppliers and that smaller group who are the best suppliers, all the while fostering a win-win relationship by sharing growth and profitability. This paper will introduce the concepts of the Supplier Performance Measurement Process (SPMP), which NOVA / TransCanada introduced in late 1997 to measure and manage its suppliers’ performance in the provision of a few strategically critical commodities. To provide context for this paper two such commodities, high pressure line pipe and high integrity pipe coatings are addressed in some detail. The application of the process to these commodities alone yielded a capital cost reduction of 6%. The paper explains in practical terms, the steps involved in the implementation of SPMP, and provides a simple process for eliciting feedback on the efficacy of the procurement process.

Qatar is one of the major natural gas (NG) producing countries, which has the world’s third-largest NG reserves besides the largest supplier of liquefied natural gas (LNG). Since the produced water (PW) generated in the oil and gas industry is considered as the largest waste stream, cost-effective PW management becomes fundamentally essential. The oil/gas industries in Qatar produce large amounts of PW daily, hence the key challenges facing these industries reducing the volume of PW injected in disposal wells by a level of 50% for ensuring the long-term sustainability of the reservoir. Moreover, it is important to study the characteristics of PW to determine the appropriate method to treat it and then use it for various applications such as irrigation, or dispose of it without harming the environment. This review paper targets to highlight the generation of PW in Qatar, as well as discuss the characteristics of chemical, physical, and biological treatment techniques in detail. These processes and methods discussed are not only applied by Qatari companies, but also by other companies associated or in collaboration with those in Qatar. Finally, case studies from different companies in Qatar and the challenges of treating the PW are discussed. From the different studies analyzed, various techniques as well as sequencing of different techniques were noted to be employed for the effective treatment of PW.

Oil and Gas industry in the last decades has increased the use and need of heavy wall thickness line pipes, in particular for onshore / offshore high pressures and high temperatures (HP/HT) and offshore deep water / ultra-deep water applications. The paper presents the results achieved by Tenaris on seamless line pipes in grades X65/X70, according to API 5L / ISO 3183, with wall thickness in a range from 40 to 60 mm and diameter between 6 5/8” and 16”, produced by hot rolling process followed by quenching and tempering. Such line pipes are able to withstand very demanding conditions, like sour environment, very high pressure and wide temperature range. In this publication, the main outcomes of laboratory testing activities on the mentioned materials will be presented as part of heavy wall line pipe qualification. For this purpose, a special testing program, including mechanical and corrosion tests, has been executed. Material demonstrated an excellent behaviour, exhibiting both mechanical, toughness and stress corrosion properties suitable for the envisaged harsh applications.

The offshore hydrocarbon basins of the world and their neighbouring countries are faced with an immense decommissioning challenge. Uncertainties in regulation and costs, coupled with limited environmental data, stifle consideration and support for alternative options to full removal. In separate regions, scientists and industry are forming partnerships and commencing research that advances understanding of regional and ecosystem-scale processes, including the habitat value of oil and gas infrastructure. With similar decommissioning-related marine research priorities being identified globally, a more coordinated approach to such research is needed: a global decommissioning marine research network and taskforce. This taskforce would not only be highly cost-effective, but it would also enable consistent approaches to science and management of the marine environment and secure protection and conservation of global marine resources. This network and taskforce would bring together leading scientists and experts in the oil and gas industry to develop an international research program that will significantly advance our understanding of the consequences to ecosystems as a result of decommissioning, as well as identify the differences and commonalities in environment–infrastructure interactions across different geographical regions. The outcomes would support sustainable installation and decommissioning practices worldwide and ensure that policies adhere to international agreements on environmental protection.

The availability of reliable, cost effective power and temperature control is critical to all facets of oil and gas operations around the globe. Dropping of global oil prices has had significant effects on long-term liquefied natural gas contracts. Oil and gas producers have experienced a decline in profits, and unprecedented pressure has been put on these companies to remain viable. Many marginal operators have experienced freezing of exploration budgets, delays on future planned expansions and the wind down of non-essential operations. Herein are four case studies from the oil and gas industry, which highlight several business solutions that assisted companies to stabilise their profits by starting production early, reducing operational down time and assisting process efficiencies.

The offshore oil and gas industry has seen a continual trend of conservatism in design for applications where a high level of strain is expected during the installation phase, leading to a tightening of the acceptable mechanical property performance of the linepipe. This is especially true with regards to longitudinal tensile properties in the strained and aged condition. Due to the expected change in data seen throughout previous projects, are the tightening expectations realistic for the manufacturers and cost effective for the client? The current condition that is widely accepted for the release of pipes suitable for high strain events is straining and ageing. However is this appropriate given that pipes are coated (aged), installed (strained) then left over time (aged)? These questions will be investigated through a series of tests and data analysis. For this project a conventional ageing as per the standard and a coating simulation were used, with all test pieces having either 0% or 1% applied strain. The test pieces for this project were tested in one of seven conditions; • As manufactured • Aged (at 200°C/5min or 250°C/1hr) • Strained and aged (1% strain applied then aged at 200°C/5min or 250°C/1hr) • Aged and strained (aged at 200°C/5min or 250°C/1hr then 1% strain applied) To ensure a direct comparison in the data the comparable test pieces were taken from the same circumferential position on the pipe. All testing for this project was carried out on material of a similar composition and future development of this work will comprise of documenting the effect on different microstructures, t/D ratios and levels of strain. It was clear from the project that changing the conditions used had an impact on the results. This could have implications for the industry in the future and has set up a scheme of development following on from this project to gain a greater understanding.

The oil and gas industry would continue to benefit from the successful application of innovative pipeline technologies. A comparison of the installed lengths of line pipe licensed by the Alberta Energy Regulatory (AER) in 2005 and 2012 indicates that composite pipeline systems have increased by 577%; a much higher increase than other types of licensed line pipe materials. The primary driver is to address corrosion that accounts for 68% of the AER-listed pipeline failures. Effective use of new flexible steel line pipe requires application within theoretically acceptable boundaries. A case history will be discussed to highlight some of the boundary conditions for flexible steel composite line pipe. Challenges to successfully use new innovative materials include industry’s ability to characterize the composition of the fluids transported by the pipeline, to characterize the composition of the fluids that permeate through the non-metallic components in some of the composite systems, and to construct systems without damage.

ABSTRACT Well integrity technologies have been in high demand within the oil and gas industry in the recent years due to two main reasons; Recent incidents and down term in industry. The recent failures and blow out incidents occurring in different parts of the world encouraged new strategies and well integrity management systems to be deployed in order to ensure wells are meeting health, safety and environmental standards. Moreover, the down term in industry caused by relatively low oil price which led oil and gas operators to scale down on exploration and drilling and alternatively work-over existing wells. It is believed that the most economical way to work-over the well is by performing data acquisition first, which enables the work-over team to do an informed decision and tackle the specified problem, saving non-productive time. One of the fast growing well integrity technologies is leak detection. Unlike conventional data acquisition techniques such as corrosion monitoring, leak detection method traces the fluids entering to the well-bore and gives a dynamic image of what's going on in a producing/injecting well. The leak detection is mainly based on passive acoustic measurement, which is typically based on listening to fluid vibration by moving through different aperture sizes, and recorded in different frequencies and amplitudes. Other measurements are recommended to add such as temperature, pressure and multiphase sensors (in case leak is suspected to be inside the tubing). The technology has been used in various locations around the world with challenging environments. The typical and most desired ones are firstly the surface casing leaks where fluids of various types enter into the annuli between casings and build up on surface. Moreover, high amounts of undesired fluids contributing to the production and the source would be hard to identify with conventional technologies.
