Abstract This paper presents a systematic workflow/methodology developed to evaluate the milling operations using coiled tubing to remove frac plugs in a well with deformed liner, post hydraulic fracturing. This paper also presents the challenges encountered during intervention and steps on how they were mitigated. The well was completed by hydraulic fracturing of five stages, each separated by a frac plug. Post stimulation, coiled tubing was mobilized to mill the plugs and provide a full bore to begin production. After spending substantial time while attempting to mill in the initial run, decision was made to POOH and inspect the BHA. It was observed that the mill had significant metal loss on the outer periphery with no damage to the mill face, which thereby concluded the presence of liner damage. A strategy was developed on how to remediate this challenge. Multiple coiled tubing diagnostic runs were performed with real-time coiled tubing capabilities, which included cleanout, camera and caliper runs. Results of each coiled tubing run performed was carefully evaluated to estimate the extent of liner damage. The caliper and video camera runs were important to determine the new reduced ID of the liner. An initial milling attempt with a 3.33" OD mill was performed, which was the smallest size based on the plug manufacturers recommendation. However due to the specific nature of liner damage it could not pass through the restriction. After further discussions, a calculated risk was taken to run with a 3.125" OD mill, which was significantly smaller than the manufacturer's recommendation, and posed an inherent threat of milling through the core of the plug, while leaving the slips intact. This however did not happen, and all four plugs were successfully milled out from the liner, allowing full bore access and well to be flowed back. This paper will act as a guideline on how to design and execute an intervention operation in deformed liners.

Abstract Index of sand production is one of the major issues faced in oil and gas wells on the Caspian region. Although there are multiple technologies to address this issue, the application of these technologies require the well to be cleaned before proceeding with any kind of remedial application. Concentric Coiled Tubing (CCT) sand vacuuming technology has brought a massive advantage for efficiently cleaning the wellbore of sub-hydrostatic wells in Caspian Sea. CCT system is the Coiled tubing string inside of Coiled tubing string which essentially provides a smaller second annular return route for the wellbore solids while simultaneously boosting the return pressure and allowing us to clean the sand where the bottomhole pressure (BHP) is low and not enough to support the circulation of fluids used for the cleanout. Cleanout fluid is pumped through the inner string to power the downhole jet pump comprised in CCT bottomhole assembly (BHA) which creates a drawdown that vacuums the solids and circulates the solids back to surface via the CCT annulus. The solid performance of the CCT system has an established track record worldwide and application of this sand cleanout technology brought a solution for recovering many wells with low BHP and has been successfully implemented since 2013, providing a method for cleaning out tons of accumulated sand particles from challenging wells in Caspian Region. With the complex system being used for cleaning out sand and also surface handling of the solids in the return flow from the wellbore, CCT sand vacuuming technology has proven to be effectively functioning in all cases that it was selected for so far. This Paper reviews the design and mechanism of the CCT sand/well vacuuming system as well as the results of several well intervention cases with its successful execution and lessons learned in Caspian region.

AbstractUsing the lessons learned from recent military operations such as Operation Inherent Resolve (OIR) from Syria and Iraq, we proposed to investigate the need for tactical military units to adapt operationally to grapple with the most common requirements specific to current operational environments, but also for those that can be foreseen in the future. In this regard, by identifying the best practices in the field that can be met at the level of some important armies, such as USA and UK, we will try to determine a common denominator of most important principles whose application may facilitate both operational and organizational adaptation necessary for tactical military units to perform missions and tasks in the most unknown future operational environments.

The Subject

The implementation of sustainability and green public procurement (GPP) initiatives in school districts has been the subject of some debate; questions over definitions and programme goals have led to inconsistency and concerns about programme achievements. The legitimacy of programmes rests not only with the announcement of policy by officials, but with adherence to policy and staff buy-in. This study examines barriers districts face, and makes recommendations based upon district experience on ways to successfully implement sustainability and GPP initiatives. A review of the literature on GPP and legitimacy in the execution of public functions within the education domain begins the study. Major components relative to best practices for GPP programmes are studied through the review of GPP-related documents from a school district in New Jersey considered as an exemplar of such programmes. Analysis of an interview with the district’s representatives suggests that, despite the normative approval such programmes receive, and widespread understanding of the rationale for pursuing such initiatives, there remain critical failings in implementation of these programmes, stemming from education, resourcing of initiatives and prioritization of green procurement in relation to other district priorities. The study concludes with lessons learned from this case, which is important given its positioning within New Jersey as an exemplar and recommendations for future research where work in this area is needed.

Purpose – The purpose of this paper is to present enterprise social networking and gamification as two potential tools to help organizations engage Millennial employees in collaboration and learning. Design/methodology/approach – The research provides general descriptions of enterprise social networking and gamification approaches, shares data on adoption of these approaches from APQC’s “2015 Knowledge Management Priorities Data Report” (based on a January 2015 survey of 524 knowledge management professionals) and includes four company examples adapted from APQC’s Connecting People to Content and Transferring and Applying Critical Knowledge best practices studies. The methodology for APQC’s best practices studies involves screening 50 or more organizations with potential best practices in a given research scope area and identifying five or six with proven best practices. APQC then conducts detailed site visits with the selected organizations and publishes case studies based on those site visits. Findings – Enterprise social networking platforms are in place at 50 per cent of organizations, with another 25 per cent planning to implement them by the end of 2015. By providing near-immediate access to information and answers, enterprise social networking helps Millennials learn the ropes at their new workplaces, gives them direct access to more knowledgeable colleagues who can assist and mentor them, and helps them improve their business outcomes by reusing knowledge and lessons learned across projects. Younger workers can also harness the power of social networking to create a sense of belonging and build their reputations in large, dispersed firms, where it is particularly difficult for them to gain visibility. A recent APQC survey indicates that 54 per cent of organizations either currently employ gamification to encourage collaboration or expect to implement it within the next three years. The rush to gamify the enterprise is, at least in part, a reflection of employers’ desire to satisfy Millennials and make them feel connected to a community of co-workers. Although games appeal to a wide range of age groups, Millennials grew up with digital interaction and tend to prefer environments that emphasize teamwork, social learning and frequent feedback – all of which can be delivered through gamification. Originality/value – The value of this paper is to introduce the value of and relationship between enterprise social networking and gamification platforms to human resource (HR) professionals looking to increase engagement and retention rates for Millennial employees.

Systemic Improvement

Academics and practitioners all too often have little or no contact with each other; the practitioner does not know what research exists that can inform their practices, and the academic does not know enough about the institutions they primarily study to make recommendations that are specific enough to inform a concrete practice or policy. I leverage my experiences both as an academic and as a data analyst and domestic violence coordinator at Family Court to outline lessons learned in the field. I detail how my academic training hindered my work as a practitioner, and how practitioners differ in terms of conducting internal research and presenting data and findings. I use my lessons learned and subsequently list several concrete practices that academics can begin to work into their work to increase communication with important stakeholders, and tailor their work to practical systemic improvement. Bridging the gap between academics and practitioners will lead to better research projects, and findings that will be able to actively enact changes within systems that academics focus on.
