Downhole casing damage is being increasingly recognized as a challenge to well integrity in the active or child well (the well being fractured) and is a distinctly different than the fracture driven incidents that have an impact on passive wells (typically offset wells). This one-day training course will examine the potential causes and possible prevention actions that may be taken during well drilling and completions steps. This course is an expansion of the instructor’s Well Integrity course, and will additionally cover fracture-driven-interactions (frac hits) and casing failures during fracturing. Students should have an existing understanding of ESP equipment and operations. George E. King of Viking Engineering is a registered professional engineer with over 43 years of experience since starting with Amoco Production Research in 1971.
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.
This paper reviews the mechanisms of initiation and the prevention of top-of-the-line corrosion (TLC). Recent research and developments are highlighted and validated to arrive at best practices for control of this significant corrosion manifestation. Water condensation and/or hydrate formation at the top of pipelines are serious design/operation considerations in pipelines. This paper reports the results of tests conducted in a new experimental setup constructed for investigating gas-hydrate risks in varied operational scenarios.
Well integrity and well barriers have been part of the exploitation for oil and gas for nearly a century, with the introduction of the blowout preventer (BOP) in the 1920s. In response to the 2010 Deepwater Horizon incident that claimed the lives of 11 men and led to the worst oil spill in United States history, the offshore industry devised new technologies and methods that would allow for a quicker response in the US Gulf of Mexico.
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.
On the basis of a case study in Equatorial Guinea, this paper demonstrates how barrier provisions with remotely controlled open/close technology capabilities enable interventions to be removed from a completion design. Every process plant presents a high number and diversity of valves that control the flow of feedstock, products, and service liquids and gases. The new approach joins well performance from production-system analysis and true valve performance from the VPC database to form an integrated system performance tool. This paper describes the first application of the 10¾-in. This paper introduces a fit-for-purpose surface-controlled formation-isolation valve (SFIV) designed for the temporary well suspension required for this strategy.
Thank you for attending the SPE Symposium. As projects require significant capital investment over long timeframes, the consistent application of sound engineering principles through the life cycle of a well must continue even during commodity price cycles. Through the progression of new technology and the practical sharing of ideas among participants, the industry will improve the collective recovery, efficiency, longevity, and liability of existing and planned thermal wells.
Approved in October, the Flow Measurement Technical Section will help engage the greater SPE technical community in flow-measurement-related issues and technologies. It will cover the full spectrum of flow measurement, including single-phase and multiphase flow. At a water treatment plant for an onshore oil field in northern Germany, formaldehyde injection was started in 2015 as a biocide. The goal of this study was to understand the chemical parameters and microbial distribution in the water system and whether formaldehyde injection was effective. To facilitate testing and comparison of products that attenuate microbially influenced corrosion under field conditions, a method using microorganisms from a low-tide, anoxic North Sea sample was developed that allows corrosion measurements to be made for corroding biofilms grown on steel surfaces.
Two intelligence groups share similar views on how the fallout from the COVID-19 pandemic has impacted OFS companies’ valuations and operations. What are the impacts of the energy crunch on OCTG demand? Ardyne’s North Sea long-term contracts were for 175 wells with possibly more to follow, while Allseas contract is for removal and disposal for the Valhall complex. The data-driven maintenance program incorporates riser condition, usage, and fatigue analysis with a risk-based inspection process. InterMoor will support Neodrill with project execution, installation services, and business development of its conductor anchor node technology.
