In Part II of this series, Antonio Pinto, senior advisor, and Celso Branco, reservoir engineer, of Petrobras discuss advances in deep offshore drilling related to the enormous Santos pre-salt basin fields of Brazil. Exploiting deepwater resources in a cost-effective manner presents a number of challenges for the industry, In the deepwater Brazilian presalt, research and development may provide solutions.
In Part II of this series, Antonio Pinto, senior advisor, and Celso Branco, reservoir engineer, of Petrobras discuss advances in deep offshore drilling related to the enormous Santos pre-salt basin fields of Brazil. Exploiting deepwater resources in a cost-effective manner presents a number of challenges for the industry, In the deepwater Brazilian presalt, research and development may provide solutions. Technology has allowed industry to develop in ever deeper water to successfully add to energy supplies, despite the high capital requirements. Petrobras has had great success in overcoming enormous technological challenges in deep water during the last decade, but challenges remain. Luke Eaton of ConocoPhillips, Darryl Herrington of LLOG Exploration, and John Thorogood, drilling global consultant provide their perspectives on deepwater technologies.
The merger of Ensco and Rowan creates a company with growing cash flow from the biggest fleet of jackup rigs, and growth potential as deepwater drilling comes back. A strong reason for removing old platforms from the Gulf of Mexico, rather than trying to squeeze more years of marginal production out of them, is hurricanes.
When the underlying cause of flow-related issues on offshore projects is unknown, an expert said an investigation of fluid flow behavior based on an understanding of the first principles of flow assurance is necessary. Past experiences with problematic situations often drive the decision-making process, and while experience may be helpful, it can also lead to the development of biases that hamper an organization’s ability to manage dynamic environments such as unconventional projects. How do mooring systems reduce risks of hurricane damage to mobile offshore drilling units?
ABS will classify a new self-elevating platform with a unique triangular monocolumn design from Calm Oceans Pte Ltd. The hollow hook will weigh close to 1000 kg and have a safe working load of 325 metric tons. ABS granted Approval in Principle to new designs for a floating production storage and offloading hull, a self-elevating unit for a mobile offshore drilling unit, and a tension-leg platform.
Proposal requests were sent to companies to solicit partnerships for the project with ADNOC and ADPower. What are the impacts of the energy crunch on OCTG demand? Technip Energies will work on a backlog comprising more than 50% in LNG-related business. Retaining the TechnipFMC name, RemainCo will generate nearly 90% of its revenue outside the US and Canada. As Oxy looks to divest billions in assets and focus more on its prime US shale fields, it sheds itself of the ISND and ISSD fields off the eastern coast of Doha.
Siemens and GE are among the companies discovering the power of an open-source innovation community to offer solutions for significant oil and gas industry challenges, such as improved corrosion monitoring. ABS granted Approval in Principle to new designs for a floating production storage and offloading hull, a self-elevating unit for a mobile offshore drilling unit, and a tension-leg platform. Whether you are involved in the design and construction of new facilities or the decommissioning of existing facilities, having a solid understanding of decom makes a lot of sense. Are you ready as all around the world offshore facilities have reached, or are reaching, the end of their design life? This study presents an overview of the structural response and failure mechanism of three-sided protected beams and proposes design solutions.
In this study, pressure-while-drilling technologies are combined with software simulations to differentiate drilling-fluid thermal expansion, wellbore ballooning, and formation influx during riserless drilling operations. A scientist hired by federal regulators to look for ways to reduce the risk of well blowouts said it is time for the oil and gas industry to treat kicks taken while drilling the same way doctors treat heart attacks.
Emerson will increase its foothold in the oil and gas industry with the purchase of software maker Paradigm. As the GE-Baker Hughes deal moves closer to finalization we now know who will be leading the combined company. The offshore drilling sector has taken a step towards consolidating an oversupplied market and Ensco will emerge from this most recent deal as the owner of the largest combined fleet of floaters and jackups. A Houston-based energy consultancy concludes that a series of downturn deals have contributed more to the resiliency of the US shale sector than a rise in oil prices.
Africa (Sub-Sahara) BG Group discovered gas in the Taachui-1 well and sidetrack in Block 1, offshore Tanzania. The drillship Deepsea Metro Idrilled Taachui-1 close to the western boundary of Block 1, then sidetracked the well and drilled to a total depth of 4215 m. The well encountered gas in a single gross column of 289 m within the targeted Cretaceous reservoir interval. Net pay totaled 155 m. Estimates of the mean recoverable gas resources are around 1 Tcf. Statoil (65%) and co-venturer ExxonMobil (35%) made a sixth discovery--the Piri-1 well--in Block 2 offshore Tanzania. Piri-1 was drilled by drillship Discoverer Americas, at a water depth of 2360 m.
