Oil and gas production in Canada’s west has led to the need for a significant increase in pipeline capacity to reach export markets. Current proposals from major oil and gas transportation companies include numerous large diameter pipelines across the Rocky Mountains to port locations on the coast of British Columbia (BC), Canada. The large scale of these projects and the rugged terrain they cross lead to numerous challenges not typically faced with conventional cross-country pipelines across the plains. The logistics and access challenges faced by these mountain pipeline projects require significant pre-planning and assessment, to determine the timing, cost, regulatory and environmental impacts. The logistics of pipeline construction projects mainly encompasses the transportation of pipe and pipeline materials, construction equipment and supplies, and personnel from point of manufacture or point of supply to the right-of-way (ROW) or construction area. These logistics movement revolve around the available types of access routes and seasonal constraints. Pipeline contractors and logistics companies have vast experience in moving this type of large equipment, however regulatory constraints and environmental restrictions in some locations will lead to significant pre-planning, permitting and additional time and cost for material movement. In addition, seasonal constraints limit available transportation windows. The types of access vary greatly in mountain pipeline projects. In BC, the majority of off-highway roads and bridges were originally constructed for the forestry industry, which transports logs downhill whereas the pipeline industry transports large equipment and pipeline materials in both directions and specifically hauls pipe uphill. The capacity, current state and location of these off-highway roads must be assessed very early in the process to determine viability and/or potential options for construction access. Regulatory requirements, environmental restrictions, season of use restrictions and road design must all be considered when examining the use of or upgrade of existing access roads and bridges. These same restrictions are even more critical to the construction of new access roads and bridges. The logistics and access challenges facing the construction of large diameter mountain pipelines in Western Canada can be managed with proper and timely planning. The cost of the logistics and access required for construction of these proposed pipeline projects will typically be greater than for traditional pipelines, but the key constraint is the considerable time requirement to construct the required new access and pre-position the appropriate material to meet the construction schedule. The entire project team, including design engineers, construction and logistics planners, and material suppliers must be involved in the planning stages to ensure a cohesive strategy and schedule. This paper will present the typical challenges faced in access and logistics for large diameter mountain pipelines, and a process for developing a comprehensive plan for their execution.

Abstract Reducing well costs in unconventional development while maintaining or improving production continues to be important to the success of operators. Generally, the primary drivers for oil and gas production are treatment fluid volume, proppant mass, and the number of stages or intervals along the well. Increasing these variables typically results in increased costs, causing additional time and complexity to complete these larger designs. Simultaneously completing two wells using the same volumes, rates, and number of stages as for any previous single well, allows for more lateral length or volume completed per day. This paper presents the necessary developments and outcomes of a completion technique utilizing a single hydraulic fracturing spread to simultaneously stimulate two or more horizontal wells. The goal of this technique is to increase operational efficiency, lower completion cost, and reduce the time from permitting a well to production of that well—without negatively impacting the primary drivers of well performance. To date this technique has been successfully performed in both the Bakken and Permian basins in more than 200 wells, proving its success can translate to other unconventional fields and operations. Ultimately, over 200 wells were successfully completed simultaneously, resulting in a 45% increase in completion speed and significant decrease in completion costs, while still maintaining equivalent well performance. This type of simultaneous completion scenario continues to be implemented and improved upon to improve asset returns.

Large Diameter Pipes

Abstract Large diameter pipes and elbows are vastly used in industry especially in mining and oil and gas production. Solid particle erosion is a common issue in these pipelines, and it is important to predict it to avoid failures. Currently, laboratory experiments reported in the literature are limited to diameters less than 4 inches. Therefore, there is not much experimental data available for large diameter elbows. However, the erosion can be predicted by CFD simulations and applying erosion equations in such elbows. The goal of this project is to examine the effects of elbow diameter and Stokes number on erosion patterns and magnitude for various flow conditions for elbow diameters of 2, 4, 8, and 12 inches. The approach of this work is to first perform CFD simulations of liquid-solid and gas-solid flows in 2-inch and 4-inch elbows, respectively, and evaluate the results by available experimental data. Then CFD simulations are carried for 2, 4, 8, and 12-inch standard elbows for various Stokes numbers corresponding to gas dominant flows with the velocity of 30 m/s, and liquid dominant flows with the velocities of 6 m/s. For gas dominant flows erosion in air and for liquid dominant flows erosion in water is investigated. All these simulations are carried for four particle sizes of 25, 75, 150, and 300 microns. The results indicate that Stokes number and diameter of elbows have significant effects on erosion patterns as well as magnitudes in this geometry. This work will have various applications, including validating mechanistic models of erosion predictions in elbows and developing an Artificial Intelligence (machine learning) algorithm to predict erosion for various flow conditions. Such algorithms are limited to the range of conditions they are trained for. Therefore, it is important to expand the database these codes are accessing. Overall, the CFD database of large diameter elbows will reduce the computational costs in the future.

This article discusses a possible scenario of energy transition in Russia, taking into account the economic structure, presence of huge oil and gas infrastructure and unique natural resources. All this allows to consider global trends of energy and economic decarbonization not only as a challenge, but also as a new opportunity for the country. Considering developed oil and gas production, transportation, refining and petrochemical infrastructure, as well as the vast territory, forest, water and soil resources, our country has unique opportunities for carbon sequestration using both biological systems and the existing oil and gas infrastructure. It is proposed to use the existing oil and gas production facilities for hydrogen generation in the processes of hydrocarbon catalytic transformation inside the reservoir. It is suggested to create and use large-scale technologies for CO2 sequestration using existing oil and gas production infrastructure. Considering high potential of the Russian Federation for carbon sequestration by biological systems, a network of Russian carbon testing areas is being developed, including one at Kazan Federal University (KFU), – the “Carbon-Povolzhye” testing area. The creation of carbon farms based on the applications at such testing areas could become a high-demand high-tech business. A detailed description of the KFU carbon testing area and its planned objectives are given.

This year marks the golden jubilee of Australia’s offshore petroleum industry after the first gas was produced from Bass Strait by Esso and BHP’s Gippsland Basin Joint Venture. For half a century our industry has been driven by technology – pioneering technical excellence and pushing the envelope in the pursuit of much needed oil and gas production. Today, the landscape in East Australia is changing and gas is at the forefront of the discussion. Declines in East Australia’s historical conventional fields have seen gas supply tighten and prices rise. There is a strong need for additional affordable and reliable gas supply. While continued improvements in technology remain a critically important enabler in developing Australia’s gas resources; global supply and demand, regulatory frameworks, and the commercial arrangements that underpin new developments are becoming more and more important. ExxonMobil Australia’s new Chairman, Nathan Fay, has a wealth of experience working with gas markets around the world. He will explain why it is so important for policymakers to establishment a stable free market environment to encourage these long-term relationships. To view the video, click the link on the right.

Cumulative Jets

The problem of certification of shaped-charge perforators appear to be very important in oil and gas production. The paper considers five aspects of the problem. First, it is a physical aspect, which means the problem is viewed from the point of view of the physics of a cumulative explosion; the second aspect is a methodological one, which implies the most desirable, permissible, unacceptable methods of certification and qualification; the next aspect is economic, it focuses on the economy on a large scale, allowing a possible loss in a small one. Perhaps, there are things that are currently more important than the most correct physical considerations and the most perfect methods, so technical and political aspects arise. The final aspect is an organizational one which implies a rational division of powers of government departments. The most important and science-intensive aspect is the physical one, as it is associated with the design, construction, and operation of shaped charges of perforators, and this is the main focus of the paper. The paper carefully analyzes the formation, movement in free space, and action on the combined obstacle: steel — concrete — rock of monolithic and powder cumulative jets from metal and composite materials. Moreover, the study comparatively assesses the penetrating action of shaped charges of perforators according to various methods, both domestic and foreign, and assesses economic, technical, political, and organizational factors in the development of the shaped charges certification procedure. Finally, the study gives recommendations for carrying out certification and qualification tests of shaped charges of perforators in Russia.

Piping inspection in Oil and Gas (O&G) production and process facilities (P&PFs) is traditionally set up by dividing the overall piping components into corrosion loops (CLs) reflecting similar corrosion (i.e. corrosion due to chemical or electro-chemical reaction and/or erosion-corrosion) environment and process conditions. Each CL is comprised of a few or several wall thickness measurement locations (WTMLs). The WTMLs are typically identified for each WTML ‘feature’ (e.g. straight section of a spool, bend, tee, weld, end cap, etc.) in a CL. Generally, inspection planning decisions regarding WTMLs are prioritized based on the results of risk based inspection (RBI) analysis. However, the degradation behavior is continuously changing due to the change in product and process conditions during the maturity of O&G production wells. This manuscript illustrates a methodology to visualize inspection coverage and corresponding defect finding rates (DFRs) for different WTML features in a selected sub-system of an oil and gas production and process facility. The suggested methodology aids the visualization of DFRs pertaining to different WTMLs, enabling inspection planners to assign inspection recommendations to the right location at the right time, minimizing ad hoc work. The approach also enables feedback to be provided to the plant inspection strategy (PIS), depending on the corresponding production field and P&PF, whilst reducing the cost of inspection to the asset owner by the minimization of ad hoc inspection recommendations.

The Australian Government formally releases new offshore exploration areas at the annual APPEA conference. Industry nominations provided guidance for the selection of gazettal areas, and in 2014 all 30 areas are supported by such nominations. The release areas are located across various offshore hydrocarbon provinces ranging from mature basins with ongoing oil and gas production to exploration frontiers. Work program bids are invited for two rounds closing on 2 October 2014 and 2 April 2015, while the closing date for four cash bid areas is 5 February 2015. Twenty-nine of the 2014 Release Areas are located along Australia’s northern margin within the Westralian Superbasin, which encompasses the rift-basins that extend from the Northern Carnarvon Basin to the Bonaparte Basin. Evolution during Gondwana break-up established a series of petroleum systems, many of which have been successfully explored, while others remain untapped. Only one area was nominated and approved for release on Australia’s southern margin. The 220 graticular blocks cover almost the entire Eyre Sub-basin of the Bight Basin. In the context of the recent commencement of large-scale exploration programs in the Ceduna and Duntroon sub-basins, this release area provides additional opportunities to explore an offshore frontier. Geoscience Australia’s new long-term petroleum program supports industry activities by engaging in petroleum geological studies that are aimed at the establishment of margin to basin-scale structural frameworks and comprehensive assessments of Australian source rocks underpinning all hydrocarbon prospectivity studies.
