Enhanced Oil Recovery (EOR) becomes increasingly important as the global crude oil reserves are being depleted. This is especially true in Indonesia where the growing internal demand exceeds its oil production as many fields are in their mature stages and thereby slowing down the overall oil production rate. Thus, it is imperative for Indonesia to look for alternative strategies to improve production from the maturing fields by adopting various tertiary techniques in order to achieve a national target of 1 MMBOPD oil production by 2030.

Field X is an onshore mature carbonate field that has been identified as a potential chemical EOR candidate. Carbonate reservoirs with moderate high reservoir temperature, 90 °C in the case of Field X, are known to be creating additional challenges for chemical EOR, particularly in formulating a tailored surfactant blend that exhibits stable behaviour, high performance and trouble-free operations.

In this paper, the surfactant-polymer (SP) formulation design, optimization and lessons learnt leading up to a successful bio-based robust chemical EOR formulation with suitable adsorption strategy for relatively low salinity (8000-9000 ppm of salinity) and high temperature (90 °C) carbonate field are presented. A multi component surfactant formulation using a novel bio-based surfactant, internal ketone sulfonate (IKS), as a primary surfactant was designed for the high temperature X reservoir. The raw materials for producing IKS surfactant that is used in this formulation is sourced and manufactured in Indonesia which also in turn creates circular economy benefits. In addition, the use of bio-based surfactant chemistry greatly decreases the carbon footprint compared to petroleum-derived chemicals and IKS has the significant advantage of improved raw material availability. The SP formulation was evaluated following a systematic workflow in order to achieve good thermal stability, SP compatibility, ultra-low interfacial tension (IFT) and favourable residual oil production with managed surfactant adsorption mitigation.

As expected, the main challenge was the reservoir conditions and the nature of rock during the course of this study which resulted in a very promising oil recovery strategy in economically realistic conditions using sustainable bio-based chemistry.

The gas-fields in the north Malay Basin and Gulf of Thailand region are well-known with the presence of high CO2 and H2S concentration in the reservoirs. Sophisticated and robust tools are needed to measure important data in order to support further development and reservoir management of the field. Thus, reservoir data such as pressure and fluid type become crucial in achieving the production target and reservoir management of this field. Fields are located in the North Malay Basin, a few hundred kilometres from the onshore border of Malaysia and Thailand. This paper describes deploying large dimension of wireline formation tester in slim hole and high deviation well which the tool option is limited in the current market.

The well design with slim hole 6-1/8" high deviation in the pay zone interval brings with them operational challenges for deploying wireline logging a critical direct measurement of downhole fluid analysis (DFA) and obtain low contamination sample which unable to provide accurate measurement under slim hole. As the Wireline formation testing (WFT) which equipped with pump out capability in the market is limited. The existing slim – WFT which can provide only a limited pumping volume leads the operator to find alternative methods due to the limitation of direct measurement to require downhole data. Hence, a more popular WFT with larger pump volume is required. A combination using a large volume WFT equipped with rollers and articulated hole finder (AHF) are appropriate to acquire downhole fluid information.

The ability of fluid characterization using a pump out formation tester coupled with downhole fluid identification has been introduced to aim an accurate decision and provide real-time data. Capability to pump-out formation fluid and acquire sample that met the expectation of contamination levels. As a result, successful determination of fluid contact, formation pressure, fluid type, reservoir mobility, and CO2 content which are the main driver to production optimization and field development. In addition, wireline data acquisition is accessible in slim hole 6-1/8" high deviation, bring more options the tool availability in the current market as only few contractors are able to provide those technologies. Using this structured approach to wireline conveyance, the operations were successfully accomplished and met the well objectives by performing pressure tests and sampling with adequate stationary time resulting in significant savings for the operator.

Deploying large dimensions of WFT in slim hole 6-1/8" high deviation wells are often a source concern for subsurface, drilling and service company personnel. However, this is the first ever implementation in the region and worldwide which pushing the limitation of the tool deployment and alternative options for operators with the well design alike.

Published: February 2024

To limit global warming to 1.5°C and reduce GHG emissions in line with the European Climate Law, large-scale deployment of carbon capture and storage (CCS) infrastructure is critical to achieving the net zero targets. The European Commission is promoting CCS as a strategic climate technology for decarbonizing hard-to-abate sectors, and as a platform for carbon dioxide removals. However, access to CO2 storage sites remains a key constraint for accelerating CCS deployment. The objective is to advance a large-scale carbon capture and storage (CCS) solution in order to develop a flexible, scalable, open-access CO2 collection, transport and storage infrastructure comprised of: CO2 terminals for onshore collection and processing to low-temperature, low-pressure liquid CO2 and LCO2 carriers that will transport the CO2 to an offshore floating injection unit (FIU) that will inject the CO2 into a deep saline aquifer for permanent storage.

Published: February 2024

The drastic reduction of greenhouse gas emissions set to the energy sector has to happen while the world continues to face an increasing demand in energy to fuel global development. To solve this complex equation the transition to gas production to enhance the existing energy mix is a recognized step to produce more affordable energy with reduced carbon footprint. Many of the gas resources still available today are subsea and bring with them specific subsea production challenges.

During the last decades the subsea industry has developed, qualified, and deployed advanced production technologies capable of significantly enhancing the recovery factor of subsea assets. Subsea boosting and processing technologies have now been deployed in many fields over the globe. They have proven their reliability and efficiency to extract more hydrocarbon from subsea reservoirs. They represent a game changing opportunity to boost the productivity of future subsea gas production while reducing the total cost of ownership of subsea assets as well as their associated carbon intensity.

Subsea compression takes advantage of more than 25 years of advancements in the boosting domain. The lessons learned in the subsea boosting domain provide an unparalleled experience with over 120 systems delivered across the globe, totaling close to 5 million hours of cumulated operating time. The benefits of subsea compression are particularly evident for deep waters and long tiebacks. Studies show that the reservoir recovery factor can be increased, to give up to 25% more gas while the total power required per volume produced can be reduced by more than 60% if subsea compression is used.

With two systems already in operation and two projects currently in execution, subsea compression proves to be a mature solution to boost subsea gas production for a large spectrum of field configurations and flow conditions. From simple system architectures capable of boosting the unprocessed wet gas stream to a more advanced solution where separation of gas and liquid is applied, the proven subsea compression technology bricks offer a unique flexibility and scalability to accommodate a wide range of reservoir sizes and system constraints. In other words, sustainably unlocking subsea gas resources to any scale.

Published: February 2024

In this work we present a coupled computational fluid dynamics and fluid-structure interaction approach for simulating the dynamics of floating offshore wind turbines (FOWTs). The multiphase flow over the platform is solved using a cartesian cut-cell approach coupled with an environmental flow generation module which can model a variety of wind-wave conditions. This is in turn coupled with a 6-degree-of-freedom fluid-structure interaction model to simulate the platform motion, while the mooring lines are represented using a dynamic lumped element model. Finally, an actuator line model (ALM) is used to model the wind turbine rotor. We have applied this methodology to study both the aerodynamic loading on the rotor and the platform dynamics of a FOWT design consisting of a 3.6-MW horizontal-axis wind turbine attached to a Stiesdal TetraSpar platform in a variety of conditions such as free decay, regular and irregular waves. The FOWT geometry and cases presented here are based on those specified by Phase IV of the OC6 (Offshore Code Comparison Collaboration, Continued with Correlation and unCertainty) project under the International Energy Agency Wind Technology Collaboration Programme (IEA Wind) Task 30. We have selected a set of cases to study the response of the FOWT to various types of loading. The first set of tests are to determine the exact equilibrium location of the FOWT for numerical simulation. In these tests we will also investigate the effect of grid resolution on the results. Next, we simulate the free decay response of the FOWT in the surge, heave, and pitch degrees of freedom. After that we investigate the turbine thrust for both floating and fixed platform configurations. Finally, we present a set of cases that illustrate the platform response to both regular and irregular waves. The simulation results match very well with the experimental data for all the cases that we have studied. Thus, this approach can be seen as a viable method to carry out predictive simulations for studying FOWT platform motions, hydrodynamic loading, and aerodynamic performance.
Innovative and Novel Development of a Dynamic Well Productivity Modeling and Performance Prediction System

Published: February 2024

The characteristics evaluation of a well and associated cost of operation can be critical aspects to effectively and efficiently developing and operating hydrocarbon wells. A well operator may consider many factors that can influence the effective and efficient development of a well, such as physical damage to the formation. This influence on the permeability is often referred to as "skin damage". The skin for a wellbore extending into a formation may include a dimensionless measure of pressure drop caused by flow restriction in the near-wellbore region of the formation. Unfortunately, the skin of a well can increase over the life of the well, which can negatively impact production performance of the well. In some instances, remediation operations, such as stimulations, are conducted on a well to reduce the well's skin in an effort to improve the well's production performance.

Provided are systems and method for analyzing hydrocarbon wells based on field historical skin profiles as well as the predicted post job gain based on field performance decline factor. It provides dynamic calculation of well skin, based on rate tests and other wellhead and reservoir parameters, to evaluate candidates for production enhancements jobs such as acid stimulation.

The innovation is a novel development which is executable by a processor to prioritize performance enhancement job candidates, based on dynamic update of formation damage to specify observed well performance and then it performs a comparison analysis between candidates based on projection of post job performance and added value. Several patents were filed to design this system and provide a platform to all future performance evaluation and enhancement to optimize operational cost and maximize additional profit.

This paper will present a system along with prototype example that is designed to perform the following operations for developing a hydrocarbon well, determining a skin increase threshold for a given period of time; for each of two or more hydrocarbon wells, identifying the hydrocarbon well as a candidate well for performance enhancement, predict production flow rate of the hydrocarbon well that corresponds to skin of zero, identifying cost of operation per barrel gained for the hydrocarbon well based on the predicted production flow rate, and determining, based on the estimated field performance decline factor, a marginal production gain in a dollar value.
The New Era of Subsea Production Systems
Authors: Müller M. , Sommer B.
Published: February 2024

The first all-electric tree system was developed in 2008. The latest, the third, generation will pave the path for offshore CO2 injection and revolutionize gas and oil production. Enhanced subsea control and real-time system monitoring will strengthen system behavior understanding and operation handling. Faster startups and shutdowns, compared to conventional electrohydraulic (EH) tree systems will increase the availability and enhance flow assurance capabilities. Long stepouts will make the system available to carbon footprint manufacturing processes and materials for carbon capture, utilization, and sequestration. Designed for shallow and ultradeep water applications, the wide range of AC/DC system compatibility achieves cost efficiency. The compact and modular tree system can be used in both greenfield and brownfield environments.

The development of the next generation of the all-electric tree system started with an in-depth analysis of the existing EH system. The EH tree was dissected, and components analyzed by subject matter experts. Valve performance, operation, and configuration were analyzed in an interdisciplinary team. Electrical actuator operational limits and performance were explored, and battery capacity and power requirements were evaluated. Expertise in functional safety was applied to develop a superior safety concept in which a detailed failure mode analysis defined the hardware and software requirements. Operational concepts were defined in state machines. Vast numbers of packaging exercises were performed. All of the concepts and subconcepts were rated and compared to the alternatives, and those that best fit the requirement were picked. The dimensions of the development required several concept cycles. Special care was taken in formulating the requirements, and the requirements were continuously reviewed.
Sustainable Metal-Organic Frameworks from Plastic Wastes Using Microwave Technique for Heavy Metal Decontamination
Authors: Sunatda A. , Kanokwan K.
Published: February 2024

Plastic waste is a significant environmental concern, with over 400 million tons generated per year, and less than 15% being recycled. Polyethylene terephthalate (PET), derived benzene-1,4-dicarboxylic acid (BDC), is the most common plastic waste which can be used as organic linker for Metal-organic frameworks (MOFs). The sustainable approach with waste management to valuable product is demonstrated by utilizing waste materials, PET bottle, to MOFs product. Not only plastic waste but waste metals such as aluminum foil metal and steel wool also can be recycled using microwave technique. Microwave synthesis can enhance efficiency and sustainability, reducing reaction time in MOFs synthesis. The developed synthesis method by microwave technique is demonstrated to produce MOFs materials from PET plastic waste, steel wool (Fe), and Aluminum foil (Al). Moreover, it can be reduced the operating expense (OPEX) cost of MOFs materials for heavy metal removal in condensate. The results showed that Al-MOF and Fe-MOF were successfully synthesized and gave the good efficiency for arsenic removal in condensate. In addition, recycled-based MOFs have proposed some future trends and challenges of OPEX cost reduction which can be used as an alternative to the conventional porous material, metal oxides and zeolites.
High Pressure Hydrocarbon Separation Performance of In-Line Piggable Liquid Removal Unit – Pseudo Dry Gas Systems
Authors: Bhaskoro P. , Liebana L. , Thomas L. , Wood T. , Roberson M. , Aman Z.
Published: February 2024

Pseudo Dry Gas (PDG) technology is proposed as an alternative concept for transporting multiphase fluids (gas, condensate, and water) for long deep-water subsea tieback developments while delivering significant reductions in Scope 1 and 2 CO2 emissions by the mitigation of compression (Reference 1). Using PDG technology, subsea multiphase pipeline networks can be extended to an excess of 300 km total length and considerably reduce the backpressure to the wells. The basis of the PDG system is to remove the liquid from the main pipeline using Piggable Liquid Removal Units. With the removal of the majority of liquid, the gravitational pressure losses in the system are considerably reduced allowing the pipeline to operate like a "Pseudo" Dry Gas system. The original prototype of this design underwent low pressure flow loop testing (Reference 2). This paper focuses on the configuration of the equipment and the supporting reasoning for high pressure and elevated temperature conditions, along with a key observations the results obtained from the testing program.

The current work involved the fabrication of a 180bar rated PDG unit, a subsea magnetic drive pump and the supporting subsea control system for flow loop testing undertaken at TÜV SÜD National Engineering Laboratories (hereinafter NEL), UK. This development program is supported by operators in conjunction with the Net Zero Technology Center. The testing program is developed to encompass the expected operational envelope that the PDG units would see in service aligned to a broad range of asset-based study work snd to consider critical non-dimensional flow assurance parameters to ensure scalability. The testing parameters considered are pressure (up to 125bar), temperature (up to 40C), and inclination (zero- and two-degrees). In addition, various liquids are considered e.g., two hydrocarbon fluids (representing oil and condensate), brine water, and hydrocarbon and water mixture. An extensive number of test points at different liquid and gas superficial velocities are included both with and without the PDG unit installed to allow for baseline comparisons. Besides pressure, temperature, level gauges and flow meters; an X-ray machine and an iso-kinetic sampling device are installed to provide liquid holdup measurements and to measure the liquid entrainment in the gas, respectively. The latter measurement data is to be used to evaluate PDG separation performance at various liquid entrainment rate.

The results show acceptable PDG separation performance at various high system pressures for all cases indicating marginal impact of increasing pressures in relation to the required performance. The liquid entrainment rate has been measured for different surface tension fluids, upstream and downstream of the PDG unit and results have been included in the calculation of the separation performance of the unit.

Published: February 2024

Bisphosphonates are commonly used to treat osteoporosis. While renal toxicity is common with pamidronate and zoledronate, few ibandronate-related cases are reported. We describe a rare case of ibandronate-associated nephrotoxicity. An 88-year-old woman was admitted for edema. She had been receiving intravenous ibandronate treatment for postmenopausal osteoporosis and had no other diagnosed diseases. She was presented with proteinuria, hypoalbuminemia (1.9 g/dL), and an elevated serum creatinine level (1.8 mg/dL). Renal biopsy revealed podocyte disease, favoring a diagnosis of focal segmental glomerulosclerosis. She was treated with diuretics, tacrolimus, and fimasartan. Steroids were avoided due to severe osteoporosis. Three months later, the edema had subsided and the laboratory findings had improved (serum albumin 3.5 g/dL, serum creatinine 0.97 mg/dL). This case emphasizes the importance of careful monitoring of proteinuria and renal function during ibandronate treatment. In older adult patients, kidney biopsy and immunosuppressive treatment may be considered based on physical activity and underlying diseases.

Published: February 2024

The potential of livestock production as a veritable means of livelihood especially in rural areas is constrained by the array of challenges. This study ascertained constraints limiting livestock production potentials among rural households in southwest Nigeria. Simple random sampling was used to select 131 and 116 rural households from Ondo and Osun, respectively. Data were analysed using mean, percentages, Pearson product-moment correlation and t-test. Respondents reared goats and sheep, poultry, and pig purposely for household use (91.9%) and sales (85.0%). Management system mostly practised was semi-intensive (71.7%). Radio ranked highest among information sources. Inadequate capital ( =2.01) limits goat/sheep production, poultry production was constrained by predators ( =1.98), while the high cost of livestock input ( =1.93) limits pig production. Poultry production constraints were significantly higher in Ondo (26.77±9.11) relative to Osun (22.72±11.38). Information sources significantly influenced constraints on livestock production (r=0.309). Household size (r=0.170) and years of experience (r=0.179) significantly relate to constraints to livestock production. The study recommends community and rural banking to facilitate easy access to loans and credit facilities; improved veterinary services and an increase in livestock extension personnel.

The study assessed gender roles in the production of African black beans (akidi) in Southeast Nigeria. Specifically, it addressed the socio-economic characteristics of the farmers, agronomic practices, gender roles, constraints, and strategies for improving the production of African black beans (ABB). A multi-stage sampling procedure was used to select 192 ABB farmers for the study. Data were collected using a semi-structured interview schedule. Data were analysed using percentage and mean statistics. Results revealed that the average age of female and male respondents was about 44 and 41 years, respectively. Men, women and youths played complementary roles in various operations in ABB production. Men (37.5%, 32.8%, 32.8% and 13.5%) and youths (32.8%, 33.9%, 34.9% and 10.9%) dominated heavy labour operations like land clearing, ploughing, harrowing and fertilizer application, respectively, while women (60.4%, 53.1%, 59.9%, 63% and 61.5%) dominated other operations like planting, harvesting, processing, storage and marketing respectively.  Therefore, all genders are involved in ABB production in the area. Efforts should be made to target different genders in ABB production. This can be done through the dissemination of improved technologies in the various production operations. This will ensure that roles are not neglected, thereby enhancing the production of African black beans.
Plants and their roles in combating contemporary global challenges
Authors: Bako Sunday Paul
Published: February 2024

This paper examined some aspects of contemporary global challenges that have mostly been occasioned by anthropogenic factors which have uncoupled ecological equilibria. These have been made more severe by pressure from the rapidly increasing human population. Some of these global challenges include deforestation, climate change, pollution of air and soils, ground and surface water scarcity/contamination, food shortages, decreased food quality, extreme poverty and decreased overall health and wellbeing. Plants provide a veritable resource for mitigation of these challenges if they are sustainably exploited to provide qualitative food, raw materials, medicine and ecosystem services. The paper also examined the trends and impacts of these global challenges and concluded that it is imperative for research and development efforts to be directed at the restoration of ecosystem balances, where stability has been disrupted, and to maintain such stability in pristine environments.
Dioscoreophyllum cumminsii (Stapf) Diels., an African underutilised indigenous fruit
Authors: Oselebe H. O. , Nnamani C. V. , Degbey H. , Achigan-Dako G.E.
Published: February 2024

Dioscoreophyllum cumminsii commonly known as Serendipity berry is one of the African indigenous fruits that has received poor attention from scientific research and funding even though it is a reservoir of many nutritional and medicinal potentials. In Nigeria, as well as in other African countries, Serendipity berry fruit is known as a tasty sweetening protein fruit. The berries contain a water-soluble and highly sweet protein called “Monellin” or “Serendip” which is one of the sweetest known naturally-occurring substances in fruits of plants. Monellin is up to 3,000 times sweeter than sucrose, with its precursor coming from protein and not carbohydrate as in sucrose. Monellin could be used as a substitute to sugar for diabetics, dieters and for a healthier life style. It has the potential of being utilised in the formulation of food and drugs to enhance the diets of other vulnerable groups. Dioscoreophyllum cumminsii is threatened and could go into extinction if appropriate actions for its propagation, production and conservation are not undertaken immediately. Currently, there is dearth of information on the consumption patterns, cultivation, management, advocacy for its valorisation and sustainable conservation of its genetic resources.

Introduction: Voluntary medical male circumcision (VMMC) is one of the key interventions against heterosexual spread of HIV. However,  its prevalence in South Sudan is not clearly understood. This study aimed to assess the prevalence and perceptions of VMMC among  University of Juba students.Method: A cross sectional descriptive study design was adopted. Data from randomly selected students from six schools of the University  of Juba were collected using a respondent-administered structured questionnaire. IBM SPSS Statistics version 23.0 was used  for data analysis. Chi-squared tests were performed to determine variables significantly associated with VMMC.Results: Amongst 390 students interviewed, the prevalence of VMMC was 41.8% and the overall male circumcision rate was 83.8%. Most  respondents expressed positive attitudes and perceptions towards VMMC. The respondents believe VMMC is an important health  programme. The decision to get circumcised is associated with age, marital status, religion and state of origin (p<0.001).Conclusion: Most participants were circumcised and perceive VMMC positively. A countrywide study and scale up of the current VMMC  programme are recommended.
Stroke rehabilitation in low resource countries: time to provide an organised service
Authors: Maanoosi Mehran
Published: February 2024

Introduction: Stroke is one of the leading causes of death and disability in lowand middle-income countries (LMICs). The proven efficacy for rehabilitation interventions in improving stroke outcomes in LMICs supports the need to strengthen the rehabilitation workforce.  Low-cost physical rehabilitation interventions requiring minimal resources, self-rehabilitation, tele-rehabilitation and involvement of  family and other carers can be a solution and improve functional outcomes.

Method: A literature search using the terms Stroke and Rehabilitation were carried out by the Chief Librarian at St. Richard’s Hospital, the  University Hospital Sussex. Four databases, namely Ovid Medline, EMBASE, CINAHL and Ebsco CINAHL, were searched using  appropriate subject headings and free text terms such as stroke and rehabilitation . We used free text terms to look for concepts  synonymous with rehabilitation in LMICs. We did not search for individual countries or continents/sub-continents.

Results: Relevant  results from 2015 to current were included. Twenty articles were finally chosen which included the most relevant and useful information for the purpose of this article.

Conclusion: Populations in LMICs are exposed to health systems which do not include rehabilitation  services. In addition, there are personal barriers to accessing quality stroke rehabilitation that could improve stroke survival and  functional outcomes. Although there have been some improvements in the development of stroke rehabilitation in some LMICs, further  investment is required to ensure that LMICs continue to receive the best quality rehabilitation services. There are measures that can be  put in place to reduce these deficiencies. Collaboration between LMICs and developed countries has been growing but this needs to be  extended, especially in training doctors in Rehabilitation Medicine and upskilling therapists. The World Health Organisation Rehabilitation  2030 is an action plan to scale up rehabilitation so that countries, especially LMICs, can be better prepared to address the evolving rehabilitation needs of populations by 2030.

Artykuł charakteryzuje wpływ wydanego w latach 1882–1883 Dziennika intymnego Henriego-Frédérica Amiela na twórczość i światopogląd Henryka Sienkiewicza, zwłaszcza zaś na jego powieść Bez dogmatu. Polski pisarz zapoznał się z dziełem Amiela na pewno na początku 1890 roku. Wydaje się jednak, że sława Amiela, potęgowana szkicami o nim Ernesta Renana i Paula Bourgeta, już wcześniej zaważyła na przeorientowaniu się twórczych zainteresowań Sienkiewicza odchodzącego pod koniec lat 80. XIX wieku od epiki historycznej ku problemom współczesności i formie powieści pierwszoosobowej. Przedmiotem analizy porównawczej jest więc głośna w Europie powieść Bez dogmatu (1891) przedstawiająca kryzys nowoczesnej tożsamości europejskiej. Analiza zarówno powieści, jak i epistolografii Sienkiewicza wykazuje liczne analogie światopoglądowe z myślą Amiela, zwłaszcza w kwestii rozumienia przyczyn kryzysu kultury europejskiej oraz człowieka drugiej połowy XIX wieku. Obaj pisarze wskazywali na destrukcyjny wpływ racjonalistycznej autoanalizy, metodologii pozytywizmu odniesionej do humanistyki oraz mechanistycznie pojmowanej idei postępu. Sienkiewicza do Amiela zbliżyły także polityczny profetyzm i stosunek do ruchów rewolucyjnych, charakterystyczny dla przedstawicieli nowoczesnego konserwatyzmu europejskiego reprezentowanego przez Edmunda Burke’a i Alexisa de Tocqevilla.

Sienkiewicz and Amiel. About a Meeting of Mind and Two Modern Intimist Strategies

The article presents the influence of Henri-Frédéric Amiel’s The Journal Intime published between 1882–1883 on the works and world-view of the 1905 Polish Nobel Prize winner Henryk Sienkiewicz, and in particular on his novel Without Dogma. The Polish writer must have read Amiel’s journal around early 1890. It seems however, that Amiel’s popularity, amplified by Ernest Renan’s and Paul Bourget’s sketches about him, had already induced a shift in Sienkiewicz’s artistic interests, who in the late 1880s moved from historical epics in favour of the issues of modernity and a first- -person-narrative novel. The comparative analysis investigates the Europe-famous novel Without Dogma (1891) touching upon the crisis of modern European identity. The analysis of the novel, as well as Sienkiewicz’s epistolography, points out to a number of world-view analogies with Amiel, especially in terms of where they saw the roots of the crisis of European culture and humanity in the second half of the 19th century. Both writers emphasized the destructive influence of rationalist self- -analysis, positivist methodology drawing on humanities, and a mechanical perception of the idea of progress. Sienkiewicz also shared Amiel’s political prophetism and approach to revolutionary movements, characteristic for representatives of modern European conservatism professed by Edmund Burke and Alexis de Tocqueville.

To Measure the Carbon Footprint of a Culture. A Case Study of a Theatrical Project

The article presents the results of carbon footprint measurements of a theatre project. For the purpose of the research, data from a survey and in-depth interviews with representatives of Polish theatres were used. Based on this data, a “model” was created, encompassing different variations of theatrical performances, including production, promotion, as well as online and on-site operations during guest performances. The analysis covers both direct emissions related to electricity consumption, transportation, and set design, as well as indirect emissions resulting from the supply chain and possible audience behaviour. The results clearly indicate that the greatest challenge in terms of the carbon footprint of a theatre project faced by cultural managers is mobility and the use of air travel for transporting theatre ensembles and set designs over long distances. Moreover, the transportation needs of the theatre ensembles and set designs for long distance travels pose a challenge. Additionally, the use of individual car transportation by audiences – even for short distances, is problematic – which could be addressed through the implementation of local partnerships. Getting familiar with this analysis can help producers, cultural managers, artists, and those responsible for shaping cultural policies to identify aspects with the greatest environmental impact and take appropriate adaptive actions. Although most of these actions will involve a profound change in traditional project management practices in the theatre, paying attention to relevant indicators, consciously developing new habits, and sharing resources provides an opportunity to expedite adaptation based on knowledge and organizational learning. These types of activities are necessary due to the unrelenting projectification of the field of culture and beyond, which causes organizations to operate in a kind of “projectocene”.
