The oil and gas industry has historically relied on experience-based, toughness target values when qualifying various components, including subsea forgings. However, this experience has been mainly with lower strength grades of steel and modest thicknesses. The increasing demand for higher yield strength steels or thicker cross sections to meet design needs necessitates the development of adequate toughness requirements to ensure safe operation of these components. The approach presented here involves utilization of fracture mechanics assessment methods to develop a more rationalized basis for toughness requirements. The guidance developed in the paper is related to critical components, both static and those that are fatigue-sensitive. And the fatigue-sensitive requirements can be applied to weld procedure qualification.

Due to increasing demand for energy around the world, the prevalence of global megaprojects within the oil and gas industry is increasing. Process pipes, valves and vessels may be manufactured and coated in China or Korea, where labour costs are comparatively low, before being transported to the final project location, such as Western Australia. During the transport and fabrication phase, coated steelwork may spend months or even years exposed to harsh offshore or coastal environments before going into service. This means coatings must be able to provide protection throughout an extensive construction phase, in addition to the in-service lifetime of the steel. This paper examines the demands on high temperature performance coatings both before and once in service. Test methodology and exposure data are reviewed with a focus on how modern aluminium pigmented silicone coatings provide a solution to the corrosion challenges faced in global megaprojects.

Within the oil and gas industry, significant costs are often incurred by the operating company during the well-construction phase of drilling operations. Specifically, the operators cost to drill a well can cost tens or hundreds of millions of USD. One specific area where significant changes in drilling operations have occurred is in the offshore environment, specifically operations from mobile offshore drilling units (MODUs). With the ever-increasing demand for oil and gas, operators globally have increased drilling budgets in an effort to meet forecasted demand. However, the increased budgets are often eroded or offset by increasing drilling costs. Therefore, operators are continually in search of new technology, processes, or procedures to help improve drilling operations and overall operational efficiencies. One Latin America operator identified a common operation as a possible area where operational cost could be easily reduced through the implementation of systems that allow the manipulation of valve manifolds remotely. Additionally, operating such valve manifolds remotely enhanced operational safety for personnel, which was an equally important consideration. This paper details the evaluation of existing equipment and procedures and a process used to develop a new remote-control system using a machine logic control (MLC) that has been designed, built, tested, and deployed successfully on MODUs operating in Latin America.

One of the most important criteria for ensuring the safe operation of the facility and increasing its durability is its reliability. Ensuring the safe operation of pipelines is in many ways a problem of increasing their reliability and durability and seems to be a complex task, which includes solving technical and technological, as well as economic and organizational aspects. To date, emergencies related to the rupture and damage to steel pipelines because of their operational wear and exposure to external factors are still the most frequent cause of accidents in the oil field. Despite the fact that numerous studies are devoted to this problem, at present it has not yet been completely resolved, and many questions still remain open. In this article, we are considering the prospects of using fiberglass and polymer-metal pipes in the oil and gas industry as an alternative to steel pipes.

In the case of assembly wellhead, a spacer spools was used to provide space and connect between parts of the wellhead. In order to design spacer spool with specified material should comply the standards and procedures of the oil and gas industry. The results of the material calculation were using the ASME BPVC guidelines. These three materials strengths were calculated if used as a body spacer spool. Based on acceptance criteria on API 6A 21st Edition, these three materials were categorized as acceptable to be used as a body spacer spool for this specification. These three materials strengths were also calculated the stress of the flange and flange rigidity criteria. Based on the acceptance criteria on ASME BPVC guidelines, the results showed that these materials can be used for flange because it had stress value under yield strength of material which was flange rigidity criteria for operating condition has 0.59 and 0.66 for testing condition because had value of rigidity that met with minimum acceptance criteria.

As the “anti-frack” movement gains momentum in society and the media, the oil and gas industry is faced with increasing demand for public participation and consultation in hydraulic fracturing operations. In Alberta, public participation has taken a number of forms, occurring during both the regulatory process and hydraulic fracturing operations themselves. This article analyzes the adequacy of these public participation opportunities by outlining the current opportunities for participation and the Alberta Court of Appeal’s rulings regarding the adequacy of notification and consultation. Ultimately, the article concludes that despite a number of new regulatory initiatives, opportunities for public participation in hydraulic fracturing operations have not increased. However, the article remains optimistic that changes can and should occur, increasing opportunities for public participation and improving the timing and quality of such consultation.

Only put off until tomorrow what you are willing to die having left undone. - Pablo Picasso, Spanish painter/sculptor, 1881-1973 It’s Time To Look at the Horizon “Opening our sails” is a metaphor that the worst of the storm has passed or is passing, and it is time to get our-selves shipshape, making necessary repairs and preparations, and get back on course. As individuals, and certainly as SPE, we must be ready to cautiously open our sails. The pandemic may be at or near its peak, and despite relatively strong economic performance in most sec-tors, we know that the global economy remains fragile. As an industry, we don’t have the luxury of waiting. We must provide energy and feedstock in advance of global needs, so it is time to get busy and plan not for what was but for what will be. The energy map, meaning the needs, resources, economies, and priorities of the world, is changing. The oil and gas industry will continue to adapt, but as I have mentioned many times, the need for the service we provide is greater now than ever before. We need to be prepared for both increasing demand and public apathy for what we do. This is nothing new, and capital investments in oil and gas should begin to increase as we enter the new year. Perhaps not at the rates we saw during the “shale revolution,” but investors know how essential we are to a strong global economy and will act accordingly. I believe Picasso was right. We must develop the discipline to sacrifice for our passions completely, for what we are doing is too important to wait and too important to sleep. Person-ally, I have a compulsive need to serve and to create. The service part probably came from having older parents who came from, let’s say, very modest circumstances, and the creative part perhaps from the desire to take things apart and put them back together with the fewest possible parts left over. I mention this because each of us has an artist, a writer, an engineer, a doctor, and maybe even a mad scientist inside them. And each of us has our own compulsions. In the post-pandemic, we need to channel that same discipline that Picasso implies. Our passions are our compass, and our energy derives from our compulsion to fulfill those passions. My challenge to you, as an industry, is to align your passions. Someone recently told me that the pandemic had provided us the opportunity of a generation to realign our priorities. I believe it is the opportunity of a lifetime. We can choose to fear the future, or we can create it. It is that simple.
