Audit findings reveal cybersecurity vulnerabilities across drilling rigs

Lessons can be learned from findings related to use of obsolete operating systems, lack of anti-malware software and security monitoring systems not being used By Austin Hay, Stewart Gillies and Walter Knur, Aberdeen Drilling Consultants The cybersecurity threat to industrial control systems (ICS) is increasing exponentially as technologies develop and systems become increasingly connected, and the lines between information technologies (IT) and operational technologies (OT) become less distinct. This article presents the findings of a sample of cybersecurity audits conducted by Aberdeen Drilling Consultants on ICS for typical rigs based on type, complexity and age. The aims of the audits were to: • Evaluate the drilling contractor’s conformance to operator cybersecurity guidelines. • Assess rig infrastructure for compliance with best ...

Case study: Technical, logistical challenges overcome to access DTS data on demand in remote location

Handling data at source, bringing it into cloud allows more data to be processed and value extracted By Andy Nelson, Tendeka Over the past decade, the implementation of the “digital oilfield” in all its guises has realized technical, safety and economical value across the life cycle of the oil and gas industry. Although a diverse range of digital technologies exist, operators continue to show reluctance to its application, meaning its uptake is still relatively slow and limited. The success of any digital oilfield project is predicated on the quality of the data structure, acquisition, communication, validation, storage, retrieval and provenance of the data. This is made difficult by the variety of sensors producing data, the multitude of data formats, challenges ...

BOP case study: Data analytics used to drive efficiency in anomaly detection, maintenance and design

Same methodology can be applied to many BOP and other equipment components to reduce operational risks and total cost of ownership By Javier Franco, Baker Hughes, a GE Company We are well into the fourth industrial revolution, Industry 4.0, which is marked by the widespread adoption of automation and data exchange in manufacturing industries and in society at large. One need only look at their phone, computer, TV or vehicle – many of which are now embedded with “smart” technology – to realize that we are all part of this revolution. By some estimates, as much as 90% of the world’s data has been generated in the past few years, and advances in smart devices have been a key contributor ...

Tangible results show big data is already transforming today’s oilfield

Examples from offshore, unconventionals and process automation demonstrate power of using data-driven decision to drive improvements By Linda Hsieh, Editor & Publisher, and Sarah Junek, Associate Editor When Gordon Moore, co-founder of Intel, predicted in 1965 that the number of transistors on a computer chip would double every two years, the oil and gas industry probably didn’t give much thought at the time to how computing capabilities would impact drilling a half-century later. Now, with approximately 20 billion transistors on a chip and the ability to store, aggregate and transmit vast amounts of data cost effectively using the internet, this digital ecosystem is rapidly making wellbore construction safer, more efficient and less environmentally impactful, said Clay Williams, National Oilwell Varco ...

Active Control Device drills deepwater MPD section in Black Sea

AFGlobal recently completed the first MPD section in a Black Sea well for Shell on Noble Drilling’s Noble Globetrotter II drillship. Key to this project is the Active Control Device (ACD), which uses a non-rotating device with an actively pressurized, co-molded element to seal the wellbore annulus and divert returns. This eliminates complex bearing assemblies and high-wear rotary seal components found in traditional rotating control devices (RCDs). In this video at the 2019 OTC in Houston on 6 May, Austin Johnson, Lead Development Engineer with AFGlobal, explains how the system works and its potential benefits. Watch the video for more information.
