Published: December 2022

Konsep green building merupakan salah satu solusi pengurangan kerusakan lingkungan, emisi karbon (penyebab utama pemanasan global), dan krisis energi. Pengimplementasian konsep ini masih sulit dari segi biaya, regulasi, sumber daya dan informasi material, serta metode kerja. Metode VE (Value Engineering) digunakan dengan mengetahui komponen pekerjaan yang bisa dioptimalkan sesuai nilai biaya dan nilai green building. Adapun tujuan penelitian adalah mengidentifikasi dan mengoptimalkan proyek berdasarkan biaya konstruksi, biaya operasi dan pemeliharaan, green material (efisiensi energi dan daya tahan material), K4 (dampak terhadap lingkungan), dan ketersediaan stok material ramah lingkungan. Metode yang digunakan berupa penilaian kualitatif (penilaian GREENSHIP HOMES, paired comparison, dan decision matrix analysis) serta kuantitatif (analisis life-cycle cost yang dikonversi menjadi nilai present-worth). Hasil penelitian menunjukkan bahwa kriteria yang paling diperhatikan responden dalam memilih material adalah ketersediaan stok material, sedangkan efisiensi energi tidak terlalu dipertimbangkan. Rekomendasi alternatif VE layak diimplementasikan pada item pekerjaan dinding bata (bata ringan), keramik lantai 2 (ubin glossy), kusen pintu tambahan dan jendela (kusen UPVC), serta rangka kanopi garasi samping dan rooftop (baja ringan) karena kinerjanya yang menguntungkan jika ditinjau dari nilai manfaat dari green building dan nilai penghematan dari life-cycle cost.

Kota Surakarta merupakan wilayah yang berdekatan dengan jalur lempeng Eurasia dan Indo-Australia. Ada perkiraaan dari Badan Nasional Penanggulangan Bencana (BNPB) bahwa jika terjadi gempa megathrust di pertemuan lempeng tersebut akan mengakibatkan gempa dengan kekuatan di atas 8 SR. Guna mengantisipasi segala kemungkinan buruk yang terjadi maka diperlukan kesadaran dan partisipasi aktif masyarakat, para pemangku kepentingan, dan tenaga kerja bidang konstruksi sehingga korban jiwa dan kerugian materi bisa ditekan seminimal mungkin. Waktu terjadinya gempa tidak dapat diperkirakan dengan pasti. Kota Surakarta pernah juga terdampak gempa Yogyakarta tahun 2006. Dari pengalaman tersebut tampak kesiapan mitigasi bencana gempa di beberapa wilayah terdampak sebagian besar masih kurang. Research Group SmartCrete, Program Studi Teknik Sipil, Universitas Sebelas Maret melakukan pengabdian masyarakat di Kelurahan Mangkubumen, Kecamatan Banjarsari, Kota Surakarta dalam rangka peningkatan kesadaran masyarakat dalam upaya mitigasi bencana gempa. Kegiatan pengabdian diawali dengan penggalian pengetahuan masyarakat tentang mitigasi bencana gempa, kemudian dilanjutkan dengan penyampaian informasi yang berkaitan dengan pengetahuan gempa dan dampaknya pada infrastruktur. Upaya-upaya mitigasi bencana gempa bumi, termasuk penerapan Standar Nasional Indonesia (SNI) gempa pada pembangunan infrastruktur juga disampaikan dalam kegiatan ini. Melalui kegiatan pengabdian ini diharapkan terjadi perbaikan pola pikir, pola tindak dan pola antisipasi serta aksi sigap dari masyarakat terhadap bahaya gempa bumi.

Se antes da COVID-19 a capacidade estatal de prover acesso e atendimento a serviços públicos já era questionável em termos de efetividade, com a rapidez da propagação, contágio e letalidade causada por esta doença pandêmica, isso se tornou um objeto de preocupação central, relacionado à questão urbana e urgente para gestores públicos. Neste contexto, o propósito deste artigo é investigar o papel da capacidade estatal e das redes de cooperação pública, especificamente os Consórcios Intermunicipais de Saúde, no controle de contágio e de letalidade da COVID-19. Como método, a regressão logística binomial foi utilizada para a modelagem considerando 2884 municípios no Brasil. Como principais resultados, a partir das análises realizadas, verificou-se que as quatro hipóteses estabelecidas revelaram evidências para sua aceitação, indicando que a participação de municípios em redes de cooperação pública, como os consórcios intermunicipais de saúde, é uma medida eficaz de gestão urbana para minimizar os efeitos da crise pandêmica. Por fim, a partir da experiência brasileira, como conclusões e contribuições do trabalho, verificou-se que os consórcios intermunicipais de saúde revelam-se elementos coadjuvantes, porém positivos no controle de contágio e de letalidade da COVID-19 em nível regional.

Published: December 2022

A busca pelo desenvolvimento sustentável vem transformando as políticas ambientais em todo o mundo, inclusive no Brasil, onde são encontradas as auditorias ambientais compulsórias com intuito de auxiliar o órgão ambiental no diagnóstico do atendimento a condicionantes legais e da licença ambiental de empresas. Apesar de existirem diferentes metodologias para avaliação do desempenho ambiental de empresas, nenhuma delas garante real qualidade ambiental nas operações, colocando em questão a validade das avaliações, quer sejam por carência de análises quantitativas e qualitativas ou até mesmo pela falta de padronização das metodologias de avaliação dessas diretivas. Assim, o presente trabalho analisou quatro relatórios de auditoria ambiental elaborados conforme a Diretriz INEA 056, Revisão 3, para identificar elementos relevantes para o processo de avaliação de desempenho ambiental de empresas do setor marítimo. Foram encontradas boas práticas desenvolvidas pela ANTAQ para qualificar a interação entre unidades marítimas e meio ambiente, com potencial para aprimorar o processo de avaliação de desempenho ambiental proposto pela Diretriz 056. Concluímos, então, que os relatórios analisados não discutiram profundamente o desempenho ambiental das empresas e, portanto, indicamos o IDA- ANTAQ como base para as avaliações de desempenho relacionadas à Diretriz 056.

The use of liposomal nanoparticles as a drug delivery system today is a promising area of modern nanopharmacology, in particular in the development of antitumor drugs. Liposomal forms of antitumor active pharmaceutical ingredients are characterized by reduced toxicity, stability, and increased antitumor activity of nanoparticle-encapsulated antitumor agent, prolonged action of the drug. Com­mercially available liposomal anticancer drugs are passively targeted drugs that accumulate in cells by passive diffusion in tumor cells due to the EPR effect of the vascular system. This review presents data from the study of antitumor activity of liposomal drugs conducted by Ukrainian scientists in recent decades. Today, the antitumor activity of liposomal forms of therapeutic agents of various natures has been proven, among them are anthracycline antibiotics, platinum drugs, semisynthetic alkaloid derivatives, natural poly­phenolic antioxidants, etc. Thus, the encapsulation of doxorubicin hydrochloride in liposomes has reduced its cardiotoxicity and other side effects, provided an opportunity to treat doxorubicin-resistant tumors. Liposomal forms of complex platinum compounds, in particular cisplatin, have been shown to be more effective than free forms of cytostatics in the treatment of cisplatin-resistant ovarian cancer. The use of polyphenolic antioxidants, quercetin and curcumin, in complex therapy can not only enhance the antitumor effect, but also have a protective effect on healthy tissues and organs.
COMPARISON OF TEMPERATURE DEPENDENCES OF ACTIVATION ENERGIES FOR FLOW AND DIFFUSION IN PURE WATER
Authors: Malafayev N. , Gaponova O. , Shkolnikova T.
Published: December 2022

The problems of calculations and the nature of intermolecular interactions forces in liquids, as their activation energies, in a wide range of temperatures of the existence of the liquid phase are considered by example of pure water. The main methodological problem in standard calculations of the activation energy is the lack of conservation of the number of molecules in the system where temperature and pressure changes. The problem is solved by writing down the Arrhenius correlation and calculating the activation energy through the kinematic viscosity, for which the number of molecules in the system is conserved. When calculating the activation energy for the diffusion process, an alternative calculation method is proposed. It’s based on the viscosity of a given liquid, which is determined much more accurately than diffusion. The calculations of the activation energies in pure water are carried out on the saturation line for the processes of flow and diffusion in the region of existence of its liquid phase, from the melting point till the critical temperature. Approximating formulas containing power and exponential contributions are obtained for them. Good correlation of the approximations with the calculations for temperatures from 0 ° С to 230 ° С is observed. It is shown that the difference between the activation energies of the processes is due to the differences in their physical mechanisms. The activation energy for the diffusion process is larger and decreases more slowly with heating than for the flow process, since all the bonds of molecules for diffusion are three-dimensional and isotropic in space. The flow process is caused by external forces that stimulate the rupture of intermolecular bonds between the layers of the fluid flow, and these interactions become quasi-two-dimensional. As a result, the activation energy for the diffusion process decreases to the critical temperature more slowly, like a root of the second degree, while for a flow it decreases linearly. For both activation energies, exponential contributions are observed near the melting point (0 ... 90 ° C). They are caused by the destruction of the remains of the crystal structure of ice in water in the form of water clusters. In the liquid phase of water, stronger and more stable in time intermolecular bonds of molecules, observed in closed hexagonal rings of water structure, which exponentially decay with increasing temperature, are retained for them.

Authors: Trotsenko A. , Grigorov A.
Published: December 2022

The article considers the possibility of expanding the range of chemicals that exhibit their high anti-corrosion properties in hydrocarbons and can be used as additives to motor fuels through the use of 1,3-diphenyltriazene. This substance belongs to the class of diazocompounds and its anticorrosive properties are determined by the adsorption capacity in contact with the metal surface, due to the presence in the molecule of nitrogen-containing active groups that form a donor-acceptor (coordination) bond with the metal surface.

Studies of anticorrosive properties were performed on metal plates (copper and steel, grade 3), located in the model environment, which consisted of straight-run diesel fraction (240-350 ° C) obtained from gas condensate with the addition of 1% of the mass. 1,3-diphenyltriazene in which was injected 0.1% of the mass. a solution of 97% acetic acid or 0.5% of the mass. aqueous solution of 10% NaCl. The anticorrosive properties of the specified model environment were studied both in static (soft) conditions at 20 ° C, periodic stirring at a speed of 100 rpm. for 90 days, and in dynamic (hard) conditions at 50 ° C, continuous stirring at a speed of 500 rpm, aeration 1.5 dm3 / min for 120 hours.

It was found that in those samples where there was 1% of the mass. 1,3-diphenyltriazene on the surface of metal plates formed a protective film, as evidenced by the change in color of the metal plate, and the absence of signs of corrosion on the surface, as well as a slight increase in its mass (within 0.0002 ÷ 0.0003 g). In samples where there was no 1,3-diphenyltriazene corrosion rate (Km), for mild study conditions was 0.94 × 10-4 ÷ 5.16 × 10-4 g / (m2 × h), for harsh study conditions - 0.56 × 10-2 ÷ 1.07 × 10-2 g / (m2 × year).

The approach proposed by the authors, which takes into account the complex action of several factors (temperature, mixing, aeration and the presence of corrosive agents), allows to adequately, close to the conditions that may arise during the actual operation of facilities, to assess the effectiveness of one or another chemical to protect against corrosion of metal surfaces.

How to stretch system reliability exploiting mission constraints: A practical roadmap for industries
Authors: Mugnaini Marco , Fort Ada
Published: December 2022

Reliability analysis can be committed to companies by customers willing to verify whether their products comply with the major international standards or simply to verify the design prior of market deployment. Nevertheless, these analyses may be required at the very preliminary stages of design or when the design is already in progress due to low organizational capabilities or simple delay in the project implementation process. The results sometime maybe be far from the market or customer target with a subsequent need to redesign the whole asset. Of course, not all the cases fall in the worst scenario and maybe with some additional consideration on mission definition it is possible to comply with the proposed reliability targets. In this paper the author will provide an overview on the approach which could be followed to achieve the reliability target even when the project is still on-going providing a practical case study.
Guest Editorial: Trends in Remote Operations and Drilling Systems Automation Point to an Expanding Footprint What Comes Next and When?
Authors: de Wardt John
Published: December 2022

_

Most industry professionals know that remote operations were becoming increasingly common well before COVID-19 impacted the oil and gas drilling industry. But then during the pandemic, everyone all at once drove to reduce personnel travel and visits to the rig site.

One solution for this was remote operations. A major service company recently reported that more than 80% of its jobs worldwide have a remote component, and up to 100% on a region‑by‑region basis.

Now, evolving remote operations is a firmly established trend.

It is a trend that has gone hand in hand with automation—from automation of data gathering to automation of action sequences. As the industry became comfortable with remote, in all senses of the word (real‑time operating centers [RTOCs] and virtual centers), ideas started to form for future development.

A synopsis follows of findings from an industry survey of remote operations in drilling which suggests various stages of implementation.

Where Are We Going?

Established already are de-manning models such as directional drilling which encompasses measurement‑while‑drilling (MWD) data, mud‑logging analysts, geosteering, drilling optimization, and survey quality control. This is expected to be followed by:

Stage I: Logging‑while‑drilling (LWD), wireline logging, cementing, and pressure pumping.

Stage II: Establishing operating protocols between RTOC and wellsite while adding mud and fluids management, which will require significantly improved mud data (real‑time and at a high frequency) along with managed pressure drilling and casing running with rig crews operating with automation.

Stage III: Elevating remote decision making, enabling drilling engineers and other operating company staff to perform roles remotely.

Stage IV: A fully digitized operating system with a high degree of automation enabling remote geo‑driller (drilling the borehole).

How Will We Get There?

The new software as a service (SaaS) models in the industry are remotely enabling drilling engineers to understand more than the driller sees on their drilling control screens. This enables the industry to reimagine how operations are controlled and executed. The drilling contractors and original equipment manufacturers will need to upgrade their human‑machine interface (HMI) to advise drillers in near‑real‑time and with operational context.

Some decisions will be relinquished to the SaaS service user in the remote environment. The current trend is leading to critical operations being managed remotely, subject to communications capabilities and routine operations which are happening on-site requiring a view of or under the drill floor.

If operations are to be primarily run from site, it will require an operations room approach where all the drilling and well data are shared with on-site experts in one location (but probably not on the drill floor).
Shale Refracs: Next Big Thing, or a Piece of the Big Puzzle?
Authors: Jacobs Trent
Published: December 2022

A number of recent studies from the US shale sector are arguing that refracturing is a generally successful practice and that high oil prices make that even more true.

New research from the Eagle Ford Shale in south Texas shows that refractured wells using liners can even outperform new wells benefiting from more modern completion designs.

The developers of the liners and packers specially designed for refracs are also reporting increased interest for their technologies as the industry leans toward more sophisticated mechanical isolation techniques.

In terms of the very lowest-hanging fruit, it is believed operators in North Dakota’s Bakken Shale are sitting on some 400 openhole wells that if refractured would generate in excess of $2 billion—and that’s at $60/bbl vs. this year’s average oil price of almost $90/bbl.

But despite the apparent progress and size of the prize, it does not appear that US shale producers are any closer to refracturing on a large scale than they were 5 years ago.

Out of all the US horizontal well stimulations performed through September of this year, a little over 2% were refracs. The figure comes from Rystad Energy which identified in public data roughly 200 refractured wells out of the 8,900 total stimulations from January to September.

Most of these refracs were in the Permian Basin spanning Texas and New Mexico and involved wells of a 2018 vintage or earlier. And most of the operators active in this space completed just between 1–4 refracs during the reporting period.

The consultancy expects that as more data filters in, the count will be around 400 refracs by year’s end. That would likely be a little over 3% of total completions and roughly in line with last year’s final tally of 409 refracs. On a percentage basis, 2022 might also look similar to the 2018 peak of 570 refracs, or 3.3% of that year’s 17,000 completions.

Justin Mayorga, a senior analyst of shale research for Rystad, said the data reflect that a healthy level of activity exists in the refrac space—but there’s little chance the 2018 record will be broken anytime soon.

“It’s a very niche market,” he said. “The companies that are doing it are probably going to continue to do it, but I don’t think refracs are going to explode in numbers next year. I see stable activity that is very similar to this year’s 2–3% of total completions.”

One reason refracs hold just a fraction of the overall completions market is because they’ve only been able to establish a limited business case in a sector that remains laser-focused on bringing in new wells. To this end, many operators active in refracturing describe how they use the technique not to boost production from older wells but more so to protect the outcomes on new child wells that share the same pad.

But the biggest obstacle facing greater refrac activity in the US, according to Rystad and other analysts, is the lack of spare pumping horsepower.
If You Build a Better Sucker Rod, Will Buyers Be Willing To Change?

When the pump breaks down and the oil stops flowing, it’s mostly likely due to a failed sucker rod.

“The statistics are pretty strong. While you would think the rod pump or the progressing cavity pump is the component with the most problems, it is the rod string” that is most often to blame, said Lonnie Dunn, vice president for technology at Lifting Solutions.

That’s a critical fact for Dunn who works for the biggest maker of what are known as continuous sucker rods. Rather than connecting individual rods into a string long enough to run from the surface to the pump, a single long rod is run into the well like coiled tubing.

While he was talking up coiled sucker rods at the SPE Artificial Lift Conference and Exhibition, a competitor at the conference, ChampionX, was announcing a first: a protective anodic coating for its continuous sucker rods that prevents corrosion and reduces the drag when a rod rubs against the surrounding tubing (SPE 209751).

Unlike competitors that have relied on coatings that provide a physical barrier, ChampionX’s defense relies on a powdered metal coating that short-circuits electrochemical reactions that can cause rapid corrosion.

This is an emerging technology where the key components are long-proven. Continuous rod was patented nearly 50 years ago, and methods using anodic corrosion protection methods have been around even longer with uses ranging from protecting subsea risers to galvanized nails.

Still both ideas are new in this slow-changing service sector, where there has been little change in the dimensions of the rods, and key design elements are usually based on API specifications.

These companies are among a handful of innovators working to convince operators that a continuous rod is a better choice at a time when wells present more challenges, from wellbores that curve by design or by accident to reservoirs producing increasingly corrosive fluids.

It has been a slow change because “sucker rods have been around a long time and the product and servicing practices are well established whereas continuous rod, especially on the servicing side, represents a significant change,” Dunn said.

While there are advantages, from faster running times to reduced failures, when it comes to this long-established oilfield commodity, he suspects some customers assume “everything that can be done is done.”

Continuous rods eliminate the time required to make the hundreds of connections needed to make up a rod string. The risk of connection failures is reduced by replacing multiple rods with a long rod requiring connections only at the pumping unit on the surface and the pump downhole.

To back up the promise of more-durable rods, the companies in this sector are adding corrosion-resistant coatings. “The general consensus is that the wells are going to get more and more corrosive, and the industry will be going after oil and gas in harsher conditions,” said Alex Perri, product line director for ChampionX.

In the complete paper, the authors discuss the development of an end-to-end waterflooding-optimization system that provides monitoring and surveillance dashboards with artificial-intelligence (AI) and machine-learning (ML) components to generate and assess insights into operational efficiency in an automated manner. The system allows for fast screening of waterflooding performance at diverse levels, enabling prompt identification of opportunities for immediate uptake into an opportunity-management process and for evaluation in an AI-driven production forecast or a reservoir simulator.

Monitoring and Surveillance Dashboards

The system consists of a series of dashboards covering both subsurface and surface elements. The production data foundation, the data-management platform, can connect to multiple data sources, simplifying data-preparation and -ingestion processes.

The intelligent monitoring and surveillance section consists of monitoring and surveillance dashboards focusing on six key indicators: production scorecard, injection scorecard, injection efficiency, voidage replacement ratio, injection-water quality, advanced analytics, and opportunity management.

The system consists of different modules such as Field, Reservoir, Sector, Pattern, Offset Wells, Surface Facilities, and Advanced Analytics. Although each module contains some automation aspects, the Advanced Analytics module houses most of the automation and ML. The modules are detailed in the complete paper.
Cloud Computing Optimizes Vaca Muerta Well Spacing, Stimulation Design

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 204142, “Well Spacing and Stimulation Design Optimization in the Vaca Muerta Shale: Hydraulic Fracture Simulations on the Cloud,” by Sahil Malhotra, SPE, Alejandro Lerza, SPE, and Sergio Cuervo, Chevron/YPF Joint Venture. The paper has not been peer reviewed.

Well spacing and stimulation design are high-impact design variables that can dictate the economics of an unconventional development. The objective of the complete paper is to showcase a numerical simulation work flow with emphasis on a hydraulic fracture simulation methodology that optimizes well spacing and completion design simultaneously. The work flow is deployed using cloud computing functionality.

Objective

The Vaca Muerta shale has grown in drilling activity and overall production significantly over the past decade. The mode of development started from vertical wells with multistage hydraulic fractures, with a transition to horizontal wells in the early 2010s. Over the past few years, the designs have transitioned to fracturing designs with lower-viscosity fluids with tighter cluster spacing. These designs have demonstrated improved production in wells drilled in multiple zones.

While an emphasis has been made on optimizing stimulation designs, well spacing has not been studied thoroughly yet. The objective of the current work is to optimize well spacing and stimulation designs to maximize estimated ultimate recovery (EUR) and lower the unit development cost per barrel. Stimulation designs contain design variables including cluster spacing, clusters per stage, proppant and fluid amount, fluid type, proppant type, and perforation design. Unit development cost is defined as the capital expenditure per barrel of EUR.

Modeling Work Flow

The work flow was used on a three-well pad in a field in the Neuquén basin targeting the Vaca Muerta. Two wells were drilled and completed in the upper zone, and one well was completed in the lower zone. The pad was initially designed for four wells, but one lower-zone well was abandoned because of drilling-related issues. Well A and Well C were pumped with high-density completions (HDC) designs, and Well B was pumped with a conventional design. The HDC design involved pumping larger proppant and fluid amounts at tighter cluster spacing than in the conventional design.
