A US appeals court overturned a district court’s preliminary injunction that prevented construction on part of Energy Transfer Partners' Bayou Bridge crude oil pipeline in the Atchafalaya Basin of Louisiana. The Texas Supreme Court ruled late in April that the Railroad Commission of Texas, the state’s oil and gas regulator, does not have exclusive jurisdiction over environmental contamination cases, which can be settled in court.
Ugandan farmer James Mubona, 73, looked pensive as he sat in a blue plastic chair under a mango tree next to three of his four wives, one breastfeeding a 5-month-old baby, contemplating the imminent loss of his 22-acre farm to an oil pipeline. The construction of the Dakota Access Pipeline sparked a broad, clamorous online debate on social media platforms. But was there a communications gap between the opponents and proponents of the pipeline on Twitter? A US appeals court overturned a district court’s preliminary injunction that prevented construction on part of Energy Transfer Partners' Bayou Bridge crude oil pipeline in the Atchafalaya Basin of Louisiana. The Pipeline and Hazardous Materials Safety Administration (PHMSA) is cracking down on smaller violations in the crude oil, petroleum, and hazardous liquid industries to combat a slow rise in the number of pipeline accidents.
The BC-10 asset, located in deep water offshore Brazil, produces heavy oil in the range of 16 to 24 °API. In this article, two examples of production optimization for this field will be provided (further examples are available in the complete paper). This paper evaluates the feasibility of a number of production- and export-riser configurations for ultradeepwater applications.
New long-term contracts between offshore drillers and equipment makers reduce downtime and risks associated with key components, from blowout preventers to risers. This paper evaluates the feasibility of a number of production- and export-riser configurations for ultradeepwater applications. This paper presents results from full-scale testing of a flexible riser equipped with embedded sensors for distributed-temperature sensing (DTS).
A project spearheaded by ExxonMobil, Shell, Chevron, and the Southwest Research Institute (SwRI) has been established to advance separation technology through improved testing methods and collaboration between users and suppliers. The simplest way to measure return on investment for an offshore water treatment system is to determine whether using the system actually reduces the risk of paying a fine for violating water pollution laws.
A study using a dynamic multiphase-flow software simulated a rapid-unloading event and determined the gas fraction in the riser annulus and the effect on riser fluid levels. The Troll field is one of the largest gas producers discovered off Norway, but ensuring its long-term future required finding ways to drill wells in an increasingly fragile formation to develop its rich oil reserves. The list of wells drilled using dual gradient includes one drilled in the “eastern Gulf of Mexico,” which could be more precisely described as offshore Cuba. A previous attempt to drill an exploration well in ultradeep water in the Gulf of Mexico (GOM) did not reach its objective.
Microbial-influenced corrosion (MIC) has been implicated in few corrosion-related challenges in the well-service industry in the past. DuPont is ramping up the commercial-scale implementation of its microbial enhanced oil recovery (MEOR) method after nearly a decade of development and testing of what it says is a low-risk way to improve production from mature fields.
This paper presents a multirate-test method to detect locations and sizes of blockages in gas pipelines. This paper presents the challenges and obstacles faced in the use of a new technology for the plugging and deoiling of sections of unpiggable flowlines before decommissioning. Since 2007, an operator in Nigeria has registered a significant increase of oil-spill events caused by sabotage and oil-theft activities. The technology presented here allows detecting and locating leaks taking place at a distance from the sensor of up to 35 km.
As natural gas pipeline systems have grown larger and more complex, the importance of optimization of design and operation of pipelines has increased. This paper examines the optimization issue for the Egyptian gas transmission pipeline network. Paradoxical effects can exist when expanding the capacity of natural-gas-transportation networks. This paper derives conditions where it can be expected, how the effect can be masked, and provide analysis to support identification in larger-scale networks. The present work describes the development of a 1D steady-state isothermal reservoir/surface gas-pipeline-network model.
