In 2015 and 2017, Asset Integrity Management (AIM) System Audits were performed of a natural gas transmission and distribution company. The AIM systems were evaluated as part of a National Facilities Audit (NFA) for the Trinidad and Tobago T&T) Ministry of Energy and Energy Industries (MEEI) and for the company directly. To allow comparison of the company-sponsored audit with the NFA performed for the MEEI, the audit protocol and methodology used the same scoring system and benchmarking in both cases. This paper presents the results, divided as Notable Mentions and Opportunities for Improvement for the company. The findings are discussed in the context of the national oil & gas industry in Trinidad and Tobago, and the long-term vision and efforts of the company to improve its AIM performance.

This paper describes the process of deregulating the gas industry and the key features of the new regime. Access conditions for users of the Natural Gas Corporation's North Island transmission and distribution systems are listed and the forward-looking capacity purchase features of the model transmission contract described. The methodology for pricing is also outlined. The paper concludes with comments on competition issues and long-term gas demand growth prospects.

Advancing Aboriginal participation in the workplace comes with its challenges, and those experienced in the oil and gas industry are unique. Barriers to participation need to be regularly evaluated and addressed for success. Although Chevron Australia's focus on Aboriginal employment is fairly recent, it receives strong internal support from senior and corporate leadership. It will be important in the future to further this commitment and build ownership throughout the organisation to achieve long-term results and meet business needs and skills gaps. Camis Smith, Chevron Australia's Aboriginal Employment Strategy Manager, will share Chevron's experiences, lessons and challenges in advancing Aboriginal participation in the workplace, and reinforce its reputation as an employer of choice. Chevron is one of the world's leading integrated energy companies and through its Australian subsidiaries, has been present in Australia for more than 60 years. With the ingenuity and commitment of more than 4,000 people, Chevron Australia leads the development of the Gorgon and Wheatstone natural gas projects, and has been operating Australia's largest onshore oilfield on Barrow Island for more than 45 years.

Given the increasing use of composite materials in various industries, oil and gas industry also requires that more attention should be paid to these materials. Furthermore, due to variation in choice of materials, the materials needed for the mechanical strength, resistance in critical situations such as fire, costs and other priorities of the analysis carried out on them and the most optimal for achieving certain goals, are introduced. In this study, we will try to introduce appropriate choice for use in the natural gas transmission composite pipelines. Following a 4-layered filament-wound (FW) composite pipe will consider an offer our analyses under internal pressure. The analyses’ results will be calculated for different combinations of angles 15 deg, 30 deg, 45 deg, 55 deg, 60 deg, 75 deg, and 80 deg. Finally, we will compare the calculated values and the optimal angle will be gained by using the Approximation methods. It is explained that this layering is as the symmetrical.

The present paper presents the development effort and pre-commercial deployment of Explorer II — a semi-autonomous, self-powered, tetherless robotic platform, carrying a Remote Field Eddy Current (RFEC) sensor, for the inspection of unpiggable natural gas transmission and distribution pipelines in the 6 to 8 inch (152 to 203 mm) range, including those that feature multiple diameters, short radius and mitered bends, and tees. The system is based on a modular design that allows the system to be deployed in various configurations to carry out visual inspection and/or non-destructive evaluation (NDE) of a pipeline. The heart of this system is a RFEC sensor able to measure the pipeline’s wall thickness. In addition, two fisheye cameras at each end of the robot provide high quality visual inspection capabilities for locating joints, tee-offs, and other pipeline features. The system can operate, including launching and retrieval, in live pipelines with pressures up to 750 psig (50 bars). The system is currently being offered for pre-commercial deployments and is expected to be commercially available in the Fall of 2010.

With the rapid development of gas enterprises in this natural gas era, lean management of production and operation (especially, upstream-downstream gas source allocation) became an important premise of their long-term stable growth. Purchase and sale of gas source are the core business of gas enterprises. To maintain a stable growth, gas enterprises have to enhance the informatization of gas source management by constructing an advanced and high-efficient gas management system. To provide useful suggestions to the construction of gas management system, this paper analyzed the characteristics of gas source management and associated businesses of gas enterprises and studied the system platform technology.

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.
