Currently, about 65% of worldwide oil is produced by waterflooding, produced water re-injection (PWRI) and production with strong water support. Yet, formation damage is a serious obstacle for oilfield development. Intensive well and water management are necessary to prevent decline in well injectivity and productivity. This is the focus of the training course. We cover the major cases of formation damage, the corresponding reservoir physics, laboratory studies and mathematical modeling, and well behaviour prediction leading the optimal well and water management strategies.
This 1-day course is an introduction to design and optimization of Flow-Control-Devices (FCDs) in horizontal wells in Thermal Recovery Operations. The interaction between reservoir and FCD, and design charts created to evaluate the response of the FCD are discussed. Liquid Pool modeling: a method to calculate the liquid pool level from temperature profile in observation wells will be discussed, and an algebraic equation for liquid pool depletion based on wellbore drawdown, subcool and emulsion productivity is generated and discussed in practical examples. A minimum subcool concept (or target reservoir subcool) is discussed and calculated as a function of skin and pressure draw-down. Liner-Deployed FCDs modeling: The formulation and physics govern restriction-type (Nozzle and Orifice), frictional-type and several other types of FCDs are presented.
This paper aims to evaluate the applicability of input/output analysis to local content management as a tool to assess the relationship between the Brazilian government’s local content policy and social and economic effects of investment projects in the oil and gas and shipbuilding industry. Wärtsilä plans to develop a harbor tug design to maximize ecological operational sustainability to be used a new port facility being built in the Brazilian city of São Mateus, which will have environmental demands among the most stringent in the world.
The paper reviews the types of renewable energy used in oil and gas fields that have appeared in the literature. Use of renewables offers many advantages, including saving hydrocarbon resources, minimizing the oil industry’s GHG emissions, and enhancing its public image. Statoil selected the name “Empire Wind” for its offshore wind site located off the southern coast of Long Island, New York. The company also recently stepped into solar power in Brazil.
Geomechanics – in both completions and drilling operations – has become a critical technology in the development of Unconventional Plays. This course presents the basics of oil field geomechanics and its application to unconventional developments, specifically, the role of stress, pore pressure, mechanical properties, and natural fractures on hydraulic fracturing operations. The first portion of the course will focus on the fundamentals of oil field geomechanics including stress, mechanical properties, and failure. The latter part of the course will focus on hydraulic fracturing for Unconventional Resources with an emphasis on the characterization, geomechanics, modeling, and field aspects of Unconventionals hydraulic fracturing (hydraulic fracturing in heterogeneous rock masses with the presence of discontinuities and weakness planes). Integration is key to Unconventional developments, and geomechanics, which spans multiple disciplines, can be a useful framework for integration.
Both platforms offshore assets were shut in following a leak in ExxonMobil's 100,000 B/D pipeline system. Qatar Petroleum will delay its North Field LNG expansion in Qatar with startup in 2025. Its Golden Pass project in Texas remains on track. The startup of the deepwater field marks the beginning of production from the massive Stabroek Block, which contains an estimated 6 billion BOE. ExxonMobil estimates that at least 5 FPSOs will be producing more than 750,000 BOPD from the Stabroek Block by 2025.
The ruling protects half a million acres of land in the Amazon forest on which the Waorani have lived for centuries from being earmarked for oil drilling, campaigners said. A parade of hundreds of Waorani, members of an indigenous nation in a remote part of the Amazon, marched triumphantly through the streets of Puyo, Ecuador, celebrating a court ruling that held that the Ecuadorian government could not auction off their land for oil exploration without their consent.

Total is determined to push ahead with its plans to drill for oil in the Amazon basin, it said on 1 June as Greenpeace activists interrupted its annual general meeting in protest over the project. This paper provides a broad overview of the Great Amazon Reef System based on the first-ever video surveys of the region.
Described as Brazil’s first-ever integrated SPS and SURF project, the development will include 19 wells, approximately 130 km of rigid risers and flowlines, and 35 km of umbilicals. In a $60 to $70 oil environment, the subsea market is poised to grow around 7% annually up to 2025. But a significant portion of this activity is at risk if the price of Brent crude falls to $50 per barrel. From its record high in 2014, purchases of subsea equipment and SURF fell around 50% until reaching a low in 2018. New data suggest that the subsea market will be a top-performing oilfield service segment.
Wärtsilä’s integrated infrastructure combines the bridge systems, cloud data management, data services, decision support tools, and access to real-time information for the fleet of tankers managed by Sovcomflot, Russia’s largest shipping company. Wärtsilä plans to develop a harbor tug design to maximize ecological operational sustainability to be used a new port facility being built in the Brazilian city of São Mateus, which will have environmental demands among the most stringent in the world.
