This paper presents a Digital Twin concept aimed at assets in the oil & gas and wind industry, that provides an accurate estimate of the true fatigue life of these assets in order to unlock potential fatigue life and ultimately extend the life of assets. This concept is divided in four tiers that allow to unlock remaining fatigue life one after the other. The first tier consists of using a high-resolution finite element model of the asset, delivered by Akselos unique RB-FEA technology. The subsequent tiers consist in using data from a few strategically placed accelerometers, as well as wave radar recordings, in order to calibrate the model and estimate the real loading on the asset. This concept delivers a true digital twin of the asset and offers a compelling and costeffective method for offshore assets that are facing life time extension beyond what current methodologies can provide. The concept is being implemented on one of Shell's platforms in the Southern North Sea.
Take a quick look at some of the data points shaping upstream headlines and the movement of oil supplies around the world. A fluid technology has been developed to deposit a thin, impermeable barrier over the pores and microfractures of weak, underpressured, and otherwise troublesome formations to maintain wellbore stability and reduce formation damage.
The recent production freefall could accelerate even further as US sanctions-related deadlines pass, the US Energy Information Administration said. Take a quick look at some of the data points shaping upstream headlines and the movement of oil supplies around the world.

With the purchase, the growing, privately-held Chrysaor Holdings will expand its UK North Sea production to 185,000 BOE/D. The state-run offshore company has found a gas and condensate field that holds an estimated 250 million BOE. The latest example of the offshore sector's march toward automated wellbore construction will take shape later this year in the North Sea. Just 2 months after issuing more than a hundred licenses, the Oil and Gas Authority begins the process again for a whole new set of blocks. The company announced it would “initiate the process” of marketing its UK Central North Sea fields as part of a portfolio review.
Attendees do not require any tools for this course but a basic understanding of how a well is constructed and then operates as a producer or injector is very beneficial. This highly visual and interactive training welcomes delegate participation and questions. Delegates will leave with a better understanding of how important sharing information about a wells construction and operation can be, and how critical it is to document how the well operates and particularly any characteristics that are shown when the well is operating out of character. All persons will be given a PDF copy of all slides.
Petroleum geomechanics is defined as the interaction between the evolving earth stresses and the overburden and reservoir rock mechanical properties. A comprehensive understanding of rock mechanical behaviour is key to successful field appraisal and development. For example, 70% of the world’s oil and gas reserves are contained in reservoirs where rock failure and sand production will become a problem at some point. Wellbore stability issues have been estimated to cost the industry USD 8 billion annually. Around 80%–90% of data comes from “traditional” core and log petrophysics, but the importance of data quality control and a rigorous and consistent petrophysical interpretation is often overlooked by well construction and production engineers.
The course addresses the holistic sand management strategy implementation from geomechanics perspectives, through evaluation and implementation of appropriate solutions for minimisation of well costs and maximisation of reservoir productivity. It will look at the inter-relationships between geomechanics and operations, application of geomechanics in relation to sand production and completions, and show how geomechanics can be best applied to provide maximum value in sand management and life-of-well and field operations. The course comprehensively covers geomechanics and operational-related sand production mechanisms, laboratory simulations of sand production to provide measurement data for model calibration and validation, state-of-the-art analytical and 4-D numerical sanding predictive methodologies for life-of-well and field including scale effect, rock strength properties reduction associated with water-cut and estimation of cumulative sand volume and rate of sand production, and optimal mitigation and management of sand production taking into consideration the feasibility of deferment or elimination of sand control installation. The course is illustrated with field examples. Application of geomechanics in relation to sand production and completions in order to provide maximum value in sand management and life-of-well and field operations.
This course is an introduction to well integrity, its history, its barriers and how to apply it to wells using guidelines, standards and regulations. Following the material selection process, it goes into well construction, completion concepts and Christmas trees. Several concepts will be introduced including well operating envelope description, well handover and operate phase, well problems, change management, case studies and well abandonment. The practical course looks at a wide range of well issues and is based on the instructor's global experience. Attendees will be able to understand well problems, understand the value of data in the diagnosis and solution process, use a range of tools and techniques that will provide support for risk assessments and solutions, and deal with problems in a cost effective way.
This course probes well integrity questions with analytical models embedded in fluid flow and heat transfer principles. Attendees will learn the principles of analytical tools that enable us to diagnose and seek remediation of wellbore safety issues. This one-day training course emphasizes fundamental understanding of fluid- and heat-flow principles leading to improved production operation practices. Beyond those necessary parameters, the input of accurate flowing fluid temperature due to Joule-Thompson effect becomes equally important. To that end, both APB and SCP analyses are discussed.
