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.
Well Integrity management is looked at in three distinct stages, the first stage is during the well design which includes material selection, engineering design, cement design, coating and inhibitors and cathodic protection. The second stage is monitoring the well during the life of the well locating possible leaks and/or loss of metal. The last stage is to manage and control any well integrity issues using specialised products, services and techniques. Define the building blocks of a successful well integrity management programme Define well integrity well categorisation based on compliance to the barrier policy outlined in the regulations and develop an approach to risk management Well barriers and their verification Monitoring and surveillance of well integrity (focus on cementing and corrosion) Understand the well integrity ISO standard (calculation of MAASP etc.) To enable participants to understand the well integrity management principles and well Integrity components during the lifecycle of the well and acquire the tools and methods to eliminate and/or mitigate the loss the well integrity during design, construction and well operations. The participants will learn how to manage a well within its operating envelope which has lost its integrity and how to manage a well within its operating envelope which has lost its integrity.
US sanctions appear to have prompted a change in ownership. It is unclear how the new arrangement will impact Venezuela’s diminishing ability to export crude oil. 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.
US sanctions appear to have prompted a change in ownership. It is unclear how the new arrangement will impact Venezuela’s diminishing ability to export crude oil. 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. 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.
Data-driven, or top-down, modeling uses machine learning and data mining to develop reservoir models based on measurements, rather than solutions of governing equations. Seminole Services’ Powerscrew Liner System is a new expandable-liner hanger that is set with torsional energy from the topdrive. Stuck pipe has traditionally been a challenge for the oil and gas industry; in recent years, operators have become even more determined to reduce the effect of stuck-pipe issues. The primary purpose of this study is to develop a method that overcomes the restrictions of rock-mechanics tests with respect to unconventional shale formations. The Earth is complex in all directions, and hydrocarbon traps require closure—whether structural or stratigraphic or both—in three dimensions.
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.
Describing operational sequences, Modern Well Design presents a unified approach to well design process and walks through an overview from spudding the well through drilling and completion to startup and production. Attendees will learn elementary rock mechanics and simple ways to analyze borehole stability. The information is then applied to fracture gradient curve design, which serves as input to the well design process. Discussions regarding the potential for optimization will conclude the course. Some of the practical solutions given in the course come from many years’ experience in the North Sea, and are not published elsewhere.
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.
