Abstract
New generation Polymer-filled and jacketed wireline cased hole cables eliminate all inherent bottlenecks of traditional wireline logging cables, enabling unprecedented operational efficiency with substantial reduction of well control risk and costly maintenance. This Technology enables a Mexico operator to deliver all their Operator Field wells ahead of time, without any HSE or well control incident while gaining 9 days of early production.
Recently developed Polymer encapsulation and bonding technology completely seal Wireline cables electrical core and armors. The result is elimination of armor birdcaging (see glossary) and stranding, grease injection and associated equipment, cable gassing-up and well fluid related armor corrosion. Total armor torque balance and polymer outer jacket substantially reduce Chrome or glass coated completions damage, cable friction and maintenance requirements. The result is unprecedented well control safety, grease related environmental and reservoir damage elimination, higher operational efficiency with faster rig-up/down and tripping speeds, reduced tractor conveyance needs with improved well access in complex completions and proven early production gains.
Contrary to conventional Wireline cables, the new generation polymer encapsulated cables come with a gas blocked core and a pressure balanced sealed cable termination. Potential well fluid migration through the cable cross section is thus completely prevented. Along with the polymer jacketing, well control risk is all but eliminated. During 2018, and for the first time in Mexico, 45 cased hole interventions, 130 descents and more than 1,000,000 feet in the well polymer cable deployments were carried in a North Mexico gas field. All Perforations, Production logging and other cased hole descents were completed totally free from HSE, operational or well control issues. Logistically challenging cable maintenance trips were all but eliminated, saving substantial time and cost to all parties involved. Compared to conventional wireline operations, time saved using polymer encapsulated Wireline cables represented a 50% reduction in rig-up and rig-down time, as well as 40% operational efficiency gain. With wells delivered early to production all contractual targets were exceeded, adding 9 days of additional production of gas and condensate.
New generation Polymer encapsulated wireline cased hole cables have enabled the Mexico Operator plan and carry out efficient, safe, cost effective, and environmentally friendly Wireline Cased Hole operations, delivering producing wells ahead of time and exceeding contractual requirements.
Combined Plug Setting and Multiple Sleeve Shifting Electric Line Operation to Deliver a Precise, Highly Effective and Efficient Intervention Solution

Abstract
A plug needed to be set in a well located in the Norwegian Continental Shelf to shut off an existing production interval, followed by the opening of several pre-installed reservoir control sliding sleeves, in order to optimise oil production from the well. It was suggested by the service company that such a two- run operation could be combined into a single run to save time and cost.
An electric line deployed solution was designed to ensure high accuracy and control across the combined operation, providing power to both the plug setting and sleeve shifting tools, along with real- time command and toolstring status readout at surface. The combined setting and shifting functionality required the use of a through-wired shifting tool to enable real-time activation of the plug setting tool, which was positioned below. A bi-directional shifting tool was used, which, in conjunction with a bi- directional stroker, would enable sliding sleeve shifting in both directions, if required, during the operation. Furthermore, its dogs were retractable on command to ensure no inadvertent shifting occurred while traversing the multiple sleeve positioned in the well.
Pre-job system integration testing was done at the service company location using a mock up completion comprised of two sleeves rigged up with a tubing joint in a horizontal set-up. This tested that there was no incompatibility between the plug setting and sleeve shifting components of the combined tool string, and that no inadvertent tool hang up occurred within the completion.
The toolstring was run in hole, depth correlated and the plug set and released. Subsequent correlation was then done for the sleeve section. The real-time control and surface readout of stroker force and position enabled a precise sleeve shifting operation, and all sleeves were shifted successfully as per requirements.
The stroker also provided a means of pulling the plug when it got inadvertently stuck whilst running to set depth and the electric line winch was unable to pull the string free. Multiple release subs were also positioned in the toolstring to enable independent recovery of the plug and stroker assembly if required. In addition, a memory pressure/temperature gauge was run, which provided further validation of sleeve shifting upon download and analysis. A tractor was used to convey the toolstring across the highly deviated section of the well.
This single-run combined service solution delivered flawless operation with considerable time savings.
Digital Slickline: Case Studies Setting and Pulling Crown Plugs
Authors: Heaney F. M. , Smith C. 
Published: March 2019

Abstract
As the scope of deepwater operations increases, the need for cost-effective well servicing is paramount, particularly because of the continued challenges associated with current volatile commodity pricing. One of the first requirements on any subsea deepwater intervention with a horizontal wellhead production tree is pulling the subsea horizontal tree isolation lock mandrel plugs, commonly referred to wellhead or crown plugs. This can be a "show stopper" event if not planned correctly. Because of the critical nature of this action, the majority of operators follow a two-prong approach, with a primary plan of action and a contingency procedure, to help ensure barrier removal proceeds as planned. Although successful removal of the crown plugs is the principal concern, it needs to be completed cost-effectively for the intervention to obtain approval.
The advent of digital slickline (DSL) allows surface readout (SRO) monitoring during the removal and installation of these barriers to provide an increased level of confidence during this important phase of the operation. This paper outlines case studies of the real-time sensors available with the RF communication DSL system that was highlighted previously (Heaney et al. 2018) for pulling and setting these wellhead or crown plugs in deepwater Gulf of Mexico interventions using the traditional jarring approach. Two brands of crown plugs are available on the market, and although both pull the same, there is a difference in the installation procedure and each plug or lock has a unique SRO digital signature.
Additionally, the straight pull battery operated extended-stroke downhole power unit highlighted in McDaniel et al. (2008), Clemens et al. (2014), and Babin et al. (2015) offers a cost-effective contingency that can be deployed on the small-footprint DSL unit. This setup allows starting the operation using the traditional jarring approach, and if required because of high hydrostatic forces, the operation can easily move to a straight pull contingency without rigging down the DSL unit for maximized wellsite efficiency.
New developments as the downhole power generator was ported to DSL are discussed, notably on- command motor controls and SRO, which was traditionally only available in memory. A downhole anchor was added to the toolbox, which can be run in combination with the downhole power generator to expand effectiveness, as new production trees might not allow for a no-go landing shoulder. To address the increased water depths, the 3.59-in. extended-stroke downhole power generator was upgraded to 80,000 lbf pulling force.

Abstract
Thru-tubing uphole re-completion is a workover technique aiming to re-complete the existing wellbore by temporary abandoning the lower producing zone and subsequently perforate upper layer. There are various techniques used to temporarily abandon the lower zone worldwide. Specific to Caspian Sea development, the temporarily abandonment will only be required to set an isolation plug. However, statistically speaking, success ratio of lower zone temporary abandonment, is quite low using current plugs set in different condition of completion. In addition, the risk of deploying balance cement plug also presents significant challenge due to interval limitation between top of the cement and new perforation interval. It is deemed necessary to find a fit-for purpose solution that provides a solution to the Caspian Sea environment plug and temporary abandonment strategy. A new plug technology, metal to metal system, was introduced to provide assurance isolating the lower zone prior to perforating new upper zone. Subsequently, a wireline deployed or pipe (tubing) conveyed perforation is not an attractive solution to thru-tubing up-hole recompletion technique. A new technology to perforate lively is selected from safety and economic point of view for this specific well. The perforation was done in underbalance condition with intelligent coiled tubing. The uphole re-completion (well delivery) performance was more attractive than other conventional uphole re-completion techniques. This paper will elaborate the success of recompletion techniques by deploying multiple new technologies in the Caspian Sea.

The popular festivity known as Corpus Cristi is a clear manifestation of culture in Ecuador. It is considered a crosscultural expression of the cosmovision and iconographic symbolism of religious fusion making an evident imaginary connotation of the population. Where evident, catholics are of a vernacular world and end up being a praise in honor of the favors received from the Body of Christ and the indigenous roots of spirituality. It represents gratitude for the successful harvests obtained in the year by the Pachamama and Taita Inti. The present study aims to provide furnishings with designs of this festival, the park 13 de abril in Pujilí, which is also commonly known by locals as the Danzante Park. The methodology used was an analysis of the artistic projects developed by Panofsky where the work is reinterpreted from a designer perspective. This method is used to propose a method of extracting the iconographic and iconological elements of cultural demonstrations resulting in the innovation of the canton. Taking advantage of the values and cultural heritage of the nation and showcasing its aesthetics, a greater flow of visitors to the area is ensured as well as the dynamics of the local economy.

The growing complexity in environmental degradation requires a serious action for adopting sustainable initiatives in the different institutions design and operation. Leadership in Energy and Environmental Design (LEED), is the most widely used green building rating system in the world that helps institutions to evaluate their current sustainable performance, and provides a concise guidance for identifying and implementing practical and measurable solutions. One of the important challenges to achieve sustainability, especially in hot dry climate region, such as Jeddah city, KSA, is the urban heat island effect that contributes to energy consumption. Effat University, Jeddah is striving towards convoying the sustainable trends in developing and designing its campus, in the light of Saudi 2030 vision, which targets reducing energy consumption. This research contributes to the knowledge of rating sustainability through measuring the level of sustainability at Effat University Campus with reference to the LEED v4 rating system (Operation and Maintenance). The research focuses on site selection category, Heat Island Reduction Credit, Option 1 Non-roof Surfaces. This was carried on through quantitative methodology that based on surveying the university campus landscape elements and materials, and interviewing maintenance key persons. The results of this research would potentially help Effat University to improve the campus environmental and energy performance through recommending a set of evidence-driven actions that can help in reducing heat island effect and enhance the efficiency of the university landscape sitting and material. This would also help in moving Effat University one-step forward to develop a green campus and being LEED Certified.

Urban areas have been identified as one of the key challenges to tackle in the next decades. Most of the environmental impacts associated to urban contexts are linked to an unsustainable use of resources basically due to urban planning and society’s consumption behaviour. Currently, the paradigm of sustainable cities brought out in the past years situates urban contexts as an opportunity to reduce these impacts. There is a wide range of strategies focused on cities and their transition to a more sustainable urban model: compactness, sustainable mobility, energy efficiency, waste management and greening are some of the most relevant approaches with clear indicators and implementation plans. However, rural areas are still pending for a precise strategy that highlights their ecological added value avoiding to be defined only as “not urban”. Rural areas should be emphasized from their productivity perspective and their key role in terms of resilience and adaptation to Climate Change. In the framework of the Interreg Med Programme, Thematic Communities are working on the capitalisation of projects from different kind of approaches of application in the Mediterranean Area. Four of these communities - Renewable Energy, Green Growth, Sustainable Tourism and Efficient Buildings - have several projects that present rural areas as one common territory of intervention. The aim of this paper is to expose the standards and goals proposed by the Interreg Med Thematic Communities for Rural Areas Revitalization as a resilience strategy in the Mediterranean Region, using a cross-cutting approach. The cross-cutting approach stresses the relation among the environment, society and economy: rural liveability, increasing RES production with sharing microgrid systems & efficient buildings, as well as green economy based on sectors such as agricultural & tourism activities. These standards and results will provide reference values to shape final policies recommendations. Consequently, the present paper is based on the joint cross-thematic effort and work from four thematic communities of the Interreg MED programme, previously mentioned. It includes some references to existing research studies, but the aim is to open the path to identify new challenges of Mediterranean rural areas and find potential solutions from a holistic approach.

Published: March 2019

Environmental lighting and acoustics is highly compromised in developing countries such as the Philippines. In urban centers such as the City of Manila, the night time population which compromises mostly the younger generation experience difficulty in mobility. Furthermore the exposure to too much noise may render the population indifferent to their surroundings.España Boulevard is a main thoroughfare connecting the city of Manila’s University Belt to the eastern metropolis. The study focuses on examining the current situation of pedestrian infrastructure in the City of Manila where community and pedestrian wellbeing should be a primordial concern in one of the densest cities in the world. Universal design is a basic consideration to support the pressing need for safety and mobility of residents and transients travelling to and from the City of Manila.This initiative is in consonance with the United Nations Sustainable Development Goal Number 3 on Good Health and Wellbeing as a part of the third UN’s SDGs of 2015-2030. This serves as a foundation for programs and projects that concern the general public, specifically pedestrians and communities.A foot-survey was conducted using downloadable apps on lighting and sound intensity to assess whether they are in compliance with prescribed international standards. Photomontage on urban design proposals are presented as possible imagery of green urbanism solutions in attaining ideal metrics for both environmental lighting and acoustics.

Abstract
The development of new catalysts from abundant raw materials, generating attractive photocatalytic activity, constitutes a real challenge in the context of sustainable development concerns. In this setting, a dolomite was treated at 800 °C (D800) and then chemically modified by Ca(NO3)2 (CaD800) using a simple procedure. The resulting materials were characterized by X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy (EDS), solid state UV spectroscopy, and used as catalysts of pentachlorophenol (PCP) degradation in aqueous solutions under UV light irradiation. The treatment of dolomite at 800 °C enabled a full decarbonation of CaMg(CO3)2, with formation of CaO, Ca(OH)2, and MgO. Additional CaO was generated after chemical treatment as revealed by EDS analysis; the Ca/Mg ratio increased from 1.29 (D800) to 1.44 for CaD800. This CaO in aqueous medium hydrates by giving Ca(OH)2. CaD800 was found to be the best photocatalyst with a PCP degradation rate of 95% after only 1 h of treatment, for a CaD800/D800 degradation rate constant ratio of 1.58. In this regard, we investigated the Fourier transform infrared spectra of CaD800, PCP, and CaD800 loaded with PCP after degradation. We thus evidenced the involvement of Ca(OH)2 in the PCP degradation process. Catalytic activity was discussed through the contribution of OH radicals and electrodonation.
