Operation Case

Open hole fracturing and acid stimulation utilising the traditional cemented liner and hydro jet perforations or mechanical packers with ball-activated frac sleeves have been deployed successfully in the US and Canada for years. One of the primary concerns about the conventional liner methods is assurance of knowing where the fracture or acid is placed. There is no way to determine if there is adequate annular isolation to ensure the planned treatments are placed in the zone of interest. In cased holes, conventional methods to stimulate perforated zones through matrix and fracture acidising would require isolating and stimulating each zone separately in multiple trips. Otherwise, bull-heading treatments with large volumes of fluid would make it difficult to control the penetration rate into the fractures, and zones could not be selectively acidised. To eliminate these issues, an inflatable packer straddle system was run in eight tight CSG reservoirs in the Bowen Basin (Queensland). The system was run to stimulate these reservoirs in two vertical wells with cased hole perforations. It is understood that this was the first use of this process in Australian CSG wells. This paper addresses the main considerations of tool operation, case histories highlighting job procedures, and lessons learned from previous operations. It also addresses the use of other tools with the straddle system and possible modifications to the system to make it suitable for operational conditions where higher rates and abrasive sand-laden fluids are required.

Psychodynamic Understanding

This article aims to advance the psychodynamic understanding of imagination failures by studying lessons learned in the US government’s public inquiry into September 11th, 2001 (9/11). Analyzing the findings of The 9/11 Report, I theorize that two forms of macro-level hubris—America’s “hubris of empire-building” and Al Qaeda’s “hubris-nemesis complex”—amalgamated in a uniquely generative manner leading to events on 9/11. Previous studies of public inquiries often demonstrate that inquiry reports are monological story-telling performances used to create sense-making narratives that function hegemonically to impose a simplified version of reality to assign blame and depoliticize events in order to facilitate closure after shocking events. In contrast, findings here suggest that by constructing a critical narrative, The 9/11 Report may serve as a new type of public inquiry report that invites learning about the complex factors that underpin crisis. The article concludes by identifying fruitful areas of future research and ways to theorize further about the collective psychodynamics of macro-level hubris and the psychodynamic factors that hinder learning and contribute to imagination failures.

Terrorism and violent extremism have undoubtedly become among the top security concerns of the 21st century. Despite a robust agenda of counterterrorism since the September 11, 2001 attacks, the evolution of global terrorism has continued to outpace the policy responses that have tried to address it. Recent trends such as the foreign fighter phenomenon, the rampant spread of extremist ideologies online and within communities, and a dramatic increase in terrorist incidents worldwide, have led to a recognition that “traditional” counterterrorism efforts are insufficient and ineffective in combatting these phenomena. Consequently, the focus of policy and practice has shifted towards countering violent extremism by addressing the drivers of radicalization to curb recruitment to extremist groups. Within this context, the field of countering violent extremism (CVE) has garnered attention from both the academic and policy-making worlds. While the CVE field holds promise as a significant development in counterterrorism, its policy and practice are complicated by several challenges that undermine the success of its initiatives. Building resilience to violent extremism is continuously challenged by an overly securitized narrative and unintended consequences of previous policies and practices, including divisive social undercurrents like Islamophobia, xenophobia, and far-right sentiments. These by-products make it increasingly difficult to mobilize a whole of society response that is so critical to the success and sustainability of CVE initiatives. This research project addresses these policy challenges by drawing on the CVE strategies of Canada, the US, the UK, and Denmark to collect best practice and lessons learned in order to outline a way forward.

SEAD – a project funded by the US National Science Foundation’s DataNet program – has spent the last five years designing, building, and deploying an integrated set of services to better connect scientists’ research workflows to data publication and preservation activities. Throughout the project, SEAD has promoted the concept and practice of “active curation,” which consists of capturing data and metadata early and refining it throughout the data life cycle. In promoting active curation, our team saw an opportunity to develop tools that would help scientists better manage data for their own use, improve team coordination around data, implement practices that would serve the data better over time, and seamlessly connect with data repositories to ease the burden of sharing and publishing. SEAD has worked with 30 projects, dozens of researchers, and hundreds of thousands of files, providing us with ample opportunities to learn about data and metadata, integrating with researchers’ workflows, and building tools and services for data. In this paper, we discuss the lessons we have learned and suggest how this might guide future data infrastructure development efforts.

Abstract Given the increased demands on the production of hydrocarbons and cost-effectiveness for the Operator's development wells, the industry is challenged to continually explore new technology and methodology to improve drilling performance and operational efficiency. In this paper, two recent case histories showcase the technology, drilling engineering, and real-time optimization that resulted in record drilling times. The wells are located on shallow water in the Gulf of Mexico, with numerous drilling challenges, which typically resulted in significant Non-Productive Time (NPT). Through close collaboration with the Operator, early planning with a clear understanding of offset wells challenges, well plan that minimize drilling in the Upper Cretaceous "Brecha" Formation were formulated. The well plan was also designed to reduce the risk of stuck pipe while meeting the requirements to penetrate the geological targets laterally to increase the area of contact in the reservoir section. This project encapsulates the successful application of the latest Push-the-Bit Rotary Steerable System (RSS) with borehole enlargement technology through a proven drilling engineering process to optimize the drilling bottomhole assembly, bit selection, drilling parameters, and real-time monitoring & optimization The records drilling times in the two case histories can be replicated and further improved. A list of lessons learned and recommendations for the future wells are discussed. These include the well trajectory planning, directional drilling BHA optimization, directional control plan, drilling parameters to optimize hole cleaning, and downhole shocks & vibrations management during drilling and underreaming operation to increase the drilling performance ultimately. Also, it includes a proposed drilling blueprint to continually push the limit of incremental drilling performance through the use of RSS with hydraulics drilling reamers through the Jurassic-age formations in shallow waters, Gulf of Mexico.

Abstract Based on input from key operators in the Middle East region, a new rotary steerable system (RSS) was launched after a compressed development schedule. This paper describes the development and introduction of the larger tool sizes needed for both onshore and offshore hole sections, including hole sizes from 12 in. and up, in the Middle East. It also outlines the deliberate design of the tool for local assembly and repair. Large diameter (9-1/2 and 11 in.) RSS designs used an existing, smaller design for Middle East applications in both offshore and onshore wells as a basis. When designing these new sizes, engineers took note of lessons learned with smaller sizes of the tool and incorporated design elements for local manufacturing, assembly, and repair. The resulting simple, modular construction enables increased levels of local content and provides for significant reductions in transportation, and therefore associated emissions. Of course, although local content and sustainability are highly desirable, performance is essential, and this paper describes case histories demonstrating how well the new tool worked in real-world Middle East applications. In one notable example, the newly introduced 9 1/2-in. diameter RSS was used to drill an offshore section in the Gulf of Arabia. The tool was mobilized after two older generation RSS had become stuck for days. Consisting primarily of argillaceous limestone, the formation had a history of stuck-pipe events. The new RSS was recommended for this application because of a slicker construction, with a fully rotational bias unit, minimal bottom hole assembly (BHA) stabilization, and an optimized junk slot area, which together help to reduce stuck-pipe risks. The tool drilled to the target depth in a single run, thereby achieving all directional requirements. Notably, after reaching the target depth, the assembly was tripped out of the hole without any requirement for backreaming. This seamless exit, in turn, indicated achieving a smooth wellbore. Other case histories demonstrate results with both new sizes of this tool. The paper also discusses in detail the ability to repair locally and engage the local supply chain. Specifically with Middle East applications in mind, a new, simple RSS design in large diameter versions has demonstrated success in offshore and onshore applications across the region. The design has also proven capabilities for manufacturing and repair local to operations, which enables maximizing in-country value, optimizing use of the tools, and energizing local supply chains.

Epidemic Response

In this follow-up panel, we discuss what we have learned over the last year about responding to an epidemic or pandemic that has demonstrated a level of transmission unprecedented in the modern era. Two medical doctors that have worked on the front of this pandemic share their experiences transitioning from the “sharp end” of the response. Decisions about how to mitigate hazards have occurred at the personal, institutional, and health policy levels, in real-time, with frequent adaptation, and often in advance of concrete evidence. Over the course of the pandemic, hospital systems revised existing protocols to manage perceived risks in real time using emerging information from other centers. With the introduction of vaccines, there is a new type of risk perception. Is the vaccine perceived to be safe? Is there a disparity in perception among different population groups? That said, analyses are also complicated by emerging viral mutations with unclear implications. What factors increase or decrease public compliance with precautions? How are US education policymakers deciding about face-to-face classroom instruction? This panel includes a warnings expert, an expert on education policy, and two practicing physicians.

The US CDC has recognized moist-heat as one of the most effective and accessible methods of decontaminating N95 masks for reuse in response to the persistent N95 mask shortages caused by the COVID-19 pandemic. However, it is challenging to reliably deploy this technique in healthcare settings due to a lack of smart technologies capable of ensuring proper decontamination conditions of hundreds of masks simultaneously. To tackle these challenges, we developed an open-source wireless sensor platform---VeriMask1 ---that facilitates per-mask verification of the moist-heat decontamination process. VeriMask is capable of monitoring hundreds of masks simultaneously in commercially available heating systems and provides a novel throughput-maximization functionality to help operators optimize the decontamination settings. We evaluate VeriMask in laboratory and real-scenario clinical settings and find that it effectively detects decontamination failures and operator errors in multiple settings and increases the mask decontamination throughput. Our easy-to-use, low-power, low-cost, scalable platform integrates with existing hospital protocols and equipment, and can be broadly deployed in under-resourced facilities to protect front-line healthcare workers by lowering their risk of infection from reused N95 masks. We also memorialize the design challenges, guidelines, and lessons learned from developing and deploying VeriMask during the COVID-19 Pandemic. Our hope is that by reflecting and reporting on this design experience, technologists and front-line health workers will be better prepared to collaborate for future pandemics, regarding mask decontamination, but also other forms of crisis tech.
