Modern anesthesia is a very complex process, in which an important role is played not only by a highly qualified specialist, making quick and deliberate decisions in emergency and planned situations, but also a set of ways to solve the problems faced by him. This review provides information on pharmacological drugs – anesthetics, used to perform spinal and epidural anesthesia, which are described in chronological order. The origin of anesthetics is considered; as well as their inventors and promoters, positive and negative effects; indications and contraindications; choices of local anesthetics for various surgical interventions; methods of their application; dose and volume; and physiological effects of neuraxial blocks. In recent years, there have been global changes in the pharmacological arsenal of anesthesiologists. New pain management drugs with significant benefits have emerged. Modern anesthetics provide a longer analgesic effect than their precursors, lack significant toxic effect, do not cause significant hemodynamic changes during surgery, and have a short latency period, which allows them to be recommended for spinal, epidural and spinal-epidural anesthesia. Keywords: Local anesthetics, spinal anesthesia, epidural anesthesia, spinal-epidural anesthesia.

Objective: Clinical observations of the use of complex myocardial revascularization (YurLeon III technique) and traditional coronary artery bypass graft (CABG) in patients with diffuse atherosclerotic lesions of the coronary network are presented. A year after CABG+YurLeon III surgery, left ventricular ejection fraction (LVEF) increased from 45% to 57%, the perfusion defect according to synchro-single-photon emission computed tomography (synchro-SPECT) decreased from 30% to 5%, the overall index of total physical well-being increased from 23.81 to 53.97 and general mental well-being elevated from 46.97 to 47.57 points. With isolated CABG, the patient had an improvement in contractility, perfusion, and key indicators of quality of life (QoL) in the early stages after surgery. However, the dynamics after a year revealed a slight decrease in LVEF, and an increase of the zone of myocardial perfusion defect.

THROMBOEMBOLIC COMPLICATIONS IN PATIENTS WITH ACUTE CALCULOUS CHOLECYSTITIS
Authors: Kavka Mariya
Published: March 2023

The aim is the analysis of clinical and anamnestic, biochemical and hemostasiological parameters in thromboembolic complications in patients with acute calculous cholecystitis (ACC).

Materials and Methods. A retrospective analysis of clinical information was performed regarding 206 patients with a diagnosis of acute calculous cholecystitis, who were hospitalized in the Emergency Medical Care Hospital of Lviv (current name: St. Panteleimon Hospital of the First Territorial Medical Association of the City of Lviv) in the period from 2014 to 2018.

Results and Discussion. It was established that 2.91% of patients with ACC had thromboembolic complications, which were manifested in the form of deep vein thrombosis and PE of small branches and were more often diagnosed in patients with significantly older age (on average, 72.67±11.13 years of age). Thromboembolic complications in patients with ACC developed reliably more often in people who had concomitant pathology (hypertensive disease, IHD, COPD, liver cirrhosis, stroke). Patients with a complicated thrombotic diagnosis were also diagnosed with final non-thrombotic complications: local and general peritonitis, perivesical abscess, perforation, abdominal sepsis and subhepatic abscess. The average duration of laparoscopic cholecystectomy (LCE) in patients without complications was 60.00 [45.0-70.0] minutes, in patients with non-thrombotic complications - 62.50 [38.5-85.0] minutes, and in patients with thrombotic complications it was significantly longer - 95.0 [95.0-95.0] minutes (p<0.05).

Conclusions. In patients with complicated acute cholecystitis, thromboembolic complications with local and general peritonitis, perivesical abscess were diagnosed more often (p<0.05). Patients with complicated acute calculous cholecystitis underwent cholecystectomy (83.33% [46.48-99.96]) reliably more often than patients with uncomplicated acute cholecystitis, whereas LCE was performed only in 16.67% [0.04-53.52] of cases. Therefore, cholecystectomy lasted for more than 1 hour in 80% [38,45-99,94] of cases.

Published: March 2023

In livestock, pre-slaughter stress begins at the farm or market, continues during transport and upon arrival at the slaughterhouse, ending at slaughter. In this investigation, a survey was conducted in the slaughterhouse of Casablanca in Morocco to record the duration of the preslaughter operations and the frequency of urination in camels. Two groups of camels were constituted, the least stressed animals (Group I, n= 12) and the most stressed animals (Group II, n= 12). Group I animals had a waiting time before loading ≤ 24 h, a loading time ≤ 15 min, an unloading time ≤ 5 min, a water and food deprivation time before slaughter ≤ 24 h, a duration of accompaniment to the slaughter room ≤ 11 min and a frequency of urination during this accompaniment < 3 times. Those in group II had higher duration and frequency values for the same parameters. In addition, serum stress [cortisol (COR)], oxidant stress biomarkers [malondialdehyde (MDA)] and activities of catalase (CAT) and superoxide dismutase (SOD) were analyzed in both groups, and correlations between these biomarkers and the durations of various preslaughter operations and the frequency of urination were established. The most stressed camels (G II) showed high serum concentrations of COR and MDA, and low CAT and SOD activities by comparison to the less stressed camels (G I) (P<0.05). Significant correlations were recorded between COR, MDA, CAT and SOD, and the durations of various preslaughter operations, and between COR and the frequency of urination.

Jenseits der Konzertsäle. Klassische Musik für breite Bevölkerungsschichten in Berlin um 1900
Authors: Rademacher Wiebke
Published: March 2023

Klassische Musik gilt gemeinhin als die bürgerlichste aller Künste. Dass sie um 1900 auch im Arbeitermilieu viel gespielt wurde, ist weniger bekannt. Doch Schumann, Brahms und Haydn waren auch in Brauereisälen, Gewerkschaftshäusern und im öffentlichen Raum regelmäßig zu hören. Arbeiterturnvereine boten sie ihren Mitgliedern zur Sonntagsvergnügung, Wahlvereine spielten sie bei Parteitagen, Abendschulen zur Volksbildung und große Orchester, um ihren Kulturvermittlungsauftrag einzulösen. Rechtskonservative wie arbeiterbewegt-linke, religiöse wie politische Kräfte waren sich erstaunlich einig, dass die Verbreitung von klassischer Musik in weniger privilegierten Schichten ein sinnvolles Unterfangen sei. Wiebke Rademacher beleuchtet am Beispiel von Berlin sowohl die konkreten Aufführungskontexte, als auch die darunter liegenden Diskurse: Braucht man Mozart für ein gesundes und glückliches Leben? Ist das Bürgertum oder die Arbeiterschaft rechtmäßiger Erbe Beethovens? Muss man Noten lesen können, um Bach zu genießen? Anhand von zahlreichen Originalquellen zeichnet sie nach, wie vielfältig und lebendig das klassische Musikleben jenseits bürgerlicher Konzertsäle im Berlin des Fin de Siècle war.
Using the Invisalign® system in conjunction with extraction for the treatment of Class II malocclusion with severe anterior crowding
Authors: Hui Bon Hoa Lionel
Published: March 2023

Clear aligners are a well-established alternative to conventional fixed orthodontic appliances for treating mild-to-moderate malocclusion. This case report details the successful treatment of a 14-year-old female patient with Class II malocclusion, crowding, and dental crossbite using extraction and the Invisalign® system. Achieving satisfactory anterior guidance by correcting the anterior crossbite and reducing the overjet and overbite was the primary treatment goal. Secondary treatment objectives included upper and lower midline alignment, leveling and alignment of arches, and achieving a Class I canine relationship for adequate canine guidance. Two sets of clear aligners were chosen; the first for alignment and the second for refinement. Extraction of teeth 14 and 24 were performed during the first aligner treatment phase, with space closure achieved by the distal movement of canine and posterior teeth mesialization. The second set of aligners refined the dentition by correcting the posterior open bite and extrusion of posterior teeth. Treatment duration was 13.5 months. By the end of treatment, the Invisalign system in conjunction with tooth extraction established an ideal overbite and overjet, corrected the crossbite, and achieved a Class I canine relationship with minimal disruption to the patient’s esthetic appearance. In addition, root axes were parallel and well controlled, despite extractions and space closure. Awareness of the dental biomechanics when clear aligners and extraction are used may be imperative for yielding successful outcomes for patients with Class II malocclusion and extractions.

A new synthetic route has been developed on a large scale for the synthesis of fluphenazine hydrochloride. We started the synthesis with the cheap and readily available tert-butyl piperazine-1-carboxylate and 1- bromo-3-chloropropane.This approach is scalable nucleophilic substitution reaction between tert-butyl piperazine-1-carboxylate and 1-bromo-3- chloropropane to afford tert-butyl 4-(3-chloropropyl) piperazine-1-carboxylate, the resulting amino chloro compound was used for N-alkylation with 2- (trifluoromethyl)-10H-phenothiazine and the obtained N- alkylated product was deprotected and then Nalkylated with chloro ethanol to afford fluphenazine hydrochloride. During the synthectic approach, we identified unknown impurity which was properly isolated and analysed by spectral data. Our synthetic strategy is very effective for large scale synthesis of fluphenazine hydrochloride.

Authors: Gandhi Santosh Kumar , Mandal Badal Kumar
Published: March 2023

In this study, a rapid and sensitive stability indicating reversed phase HPLC method was developed for quantitation of Nirmatrelvir and Ritonavir simultaneously in bulk and tablet formulation. Nirmatrelvir and ritonavir were separated on a Thermo C18 column with mobile phase containing 0.01M potassium dihydrogen phosphate buffer and acetonitrile (45:55, v/v). The flow rate was 1 mL/min and detection wavelength was 272 nm. Method linearity was established over a range of 75–225 μg/mL for nirmatrelvir and 50–150 μg/mL for ritonavir. Limit of quantification was 0.694μg/mL for nirmatrelvir and 0.820μg/mL for ritonavir. The recovery (%) was 99.96 to 100.45 (Nirmatrelvir) and 100.25 to 101.35 (Ritonavir). The method precisions were 0.11% (Nirmatrelvir) and 0.33% (Ritonavir). Method was suitable to assay nirmatrelvir and ritonavir in tablet formulation (Paxlovid). Stress degradation studies have shown that this method can be implemented to assay nirmatrelvir and ritonavir in the presence of its degradants.

Nickel-based alloy corrosion in CANDU steam generators: E-pH diagrams of the Ni-NH3-H2O and Ni-CH3COO−-H2O ternary systems
Authors: Razmjoo Khollari Mohammad Amin , Zebardast Hamid , Asselin Edouard
Published: March 2023

Nuclear power plant steam generator (SG) tubes contain nickel as the main alloying element and there is concern about their corrosion. We optimized models for calculating the high-temperature and high-pressure thermodynamic properties of common nuclear alloy elements and then, calculated the E-pH diagrams for nickel in different concentrations of ammonia or acetate ion between 100 to 260 ℃ at 4.7 MPa. This information is used to predict the corrosion behaviour for nickel in the secondary circuit conditions of CANDU SGs. Based on the results, nickel ammonia and nickel acetate complexes are not stable at low concentrations of ammonia or acetate ion. However, increasing the ammonia or acetate ion concentration resulted in the predominance of Ni(NH3)n2+ or Ni(Ac)n(2−n) at the expense of Ni2+ and NiO, indicating a higher risk of nickel corrosion. Calculations showed that under normal operating conditions with [NH3]tot=5×10−5 and [CH3COO−]tot=10−8 m at 260 ℃ and 4.7 MPa, nickel will be passivated as NiO, preventing the rapid degradation of nickel-based alloys. However, in the presence of a crevice that allows the acetate ion to concentrate, nickel would dissolve in the form of the Ni2+ ion, endangering safe operation of CANDU SGs.

Programming artificially a sequence of organic-metal oxide multilayers (superlattices) by using atomic layered depositions (ALD) is a fascinating and challenging issue in material chemistry. However, the complex chemical reactions between ALD precursors and organic layer surfaces have limited their applications for various material combinations. Here we demonstrate the impact of interfacial molecular compatibility on the formation of organic-metal oxide superlattices using ALD. The effects of both organic and inorganic compositions on the metal oxide layer formation processes onto self-assembled monolayers (SAM) were examined by using scanning transmission electron microscopy (STEM), in-situ quartz crystal microbalance (QCM) measurements, and Fourier-transformed infrared spectroscopy (FT-IR). These series of experiments reveal that the terminal group of organic SAM molecules must satisfy two conflicting requirements, the first of which is to promptly react with ALD precursors and the second is not to bind strongly to the bottom metal oxide layers to avoid undesired SAM conformations. OH-terminated phosphate aliphatic molecules, which we have synthesized, were identified as one of the best candidates for such a purpose. Molecular compatibility between metal oxide precursors and the -OHs must be properly considered to form superlattices. In addition, it is also important to form densely packed and all-trans-like SAMs to maximize the surface density of reactive -OHs on the SAMs. Based on these design strategies for organic-metal oxide superlattices, we have successfully fabricated various superlattices composed of metal oxides (Al-, Hf-, Mg-, Sn-, Ti-, Zr oxides) and their multilayered structures.
Boosting Circularly Polarized Luminescence from Alkyl-Locked Axial Chirality Scaffold by Restriction of Molecular Motions
Authors: Huang Wenbin , Zhou Kang , Zhao Engui , He Zikai
Published: March 2023

Boosting the circularly polarized luminescence of small organic molecules has been a stubborn challenge because of weak structure rigidity and dynamic molecular motions. To investigate and eliminate these factors, here, we carried out the struc-ture-property relationship studies on a newly-developed axial chiral scaffold of bidibenzo[b,d]furan. The molecular rigidity was finely tuned by gradually reducing the alkyl-chain length. The environmental factors were considered in solution, crystal, and polymer matrix at different temperatures. As a result, a significant amplification of the dissymmetry factor glum from 10-4 to 10-1 with a 146-fold magnification was achieved, corresponding to the situation from (R)-4C in solution to (R)-1C in polymer film at room temperature. A synergistic strategy of increasing the intramolecular rigidity and enhancing the inter-molecular interaction to restrict the molecular motions was thus proposed to improve circularly polarized luminescence. The though-out demonstrated relationship will be of great importance for the development of high-performance small organic chiroptical systems in the future.
A Flexible, Modular Platform for Multidimensional Ion Mobility of Native-like Ions
Authors: Eaton Rachel M. , Zercher Benjamin , Wageman AnneClaire , Bush Matthew F.
Published: March 2023

Native ion mobility (IM) mass spectrometry (MS) is used to probe the size, shape, and assembly of biomolecular complexes. IM-IM-MS can increase the amount of information available in structural studies by isolating subpopulations of structures for further analysis. Previously, IM-IM-MS has been implemented using the Structures for Lossless Ion Manipulations (SLIM) architecture to probe the structural stability of gas-phase protein ions. Here, a new multidimensional IM instrument constructed from SLIM devices is characterized using multiple operational modes. In this new design, modular devices are used to perform all ion manipulations, including initial accumulation, injection, separation, selection, and trapping. Using single-dimension IM, collision cross section (Ω) values are determined for a set of native-like ions. These Ω values are within 3% of those reported previously based on measurements using RF-confining drift cells. Tandem IM experiments are performed on a sample of ubiquitin ions that contain both compact and partially unfolded structures, demonstrating that this platform can isolate subpopulations of structures. Finally, additional modes of analysis, including multiplexed IM and inverse IM, are demonstrated using this platform. The ability of this platform to quickly switch between different modes of IM analysis makes it a highly flexible tool for studying protein structures and dynamics.

The mangrove ecosystem is one of the most productive ecosystems on earth. This ecosystem provides a lot of functions for the living organism inhabiting here, such as fishes, mollusks, echinoderms, crustaceans, ect. The mangrove crab is one of the common crustaceans that can be found in the mangrove. This Purtunidae crab is very popular due to their role in the food chain as well as for the economic income that has a high value in the market. However, overexploitation may decrease the crab population. This study aimed to investigate the abundance and occurrence of the mangrove crabs from Munjang mangrove, Bangka Belitung Island from August 2020 to June 2021 using baited traps with the line transect method at four zones. A total of four species of mangrove crabs, Scylla olivacea, S. paramamosain, S. serrata and S. tranquebarica, were found in this location and dominated by S. serrata. Shannon diversity index (H’) was a in low category (<1), evenness index range (J) from 0.35 to 0.89, and there was dominant species in this study. The bed sediment iswas dominated by the muddy clay substratum except in zone 4 with sandy. Overall, this location is a suitable habitat for the Scylla spp. And better management is urgently needed before these crabs are exploited by humans.

Published: March 2023

Advancements in educational technology have kept teaching and learning undisrupted during unprecedented times. Individual and collaborative web-based learning activities have addressed language teachers’ dilemma on how to approach teaching and learning remotely. Weblogging characterised by online journals has been considered to address students’ difficulty in mastering writing as a productive skill. In this study, the effectiveness of a collaborative weblog-based (CWB) project approach was explored. Utilising a quasi-experimental design, 56 English pre-service teachers enrolled in a state university were purposively selected to be the study participants. The validated pre-post-test questionnaire, course syllabus, lesson exemplars, and scoring rubric were used to gather the needed data on students’ writing skills. Results of the paired t-test revealed a significant increase in the three aspects: organisation, elaboration and grammar, usage and mechanics. The CWB project approach is an alternative way to improve students’ writing performance. It is recommended that CWB project may be used by teachers handling writing courses and other related disciplines to address writing proficiency.

Authors: Arwani Agus Yusuf
Published: March 2023

This study aims to clarify the role of the Arabic language in Islamic Economy through a library research. It used descriptive approach combined with content analysis approach. Arabic is a compulsory language. When Islam expanded and came into contact with other civilizations, Arabic acted as a bridge of scholarship through the movement of translation. This movement got the right momentum, not only from the ulama, but also political and financial support from the umara, so the synergy of power and knowledge transformed into a powerful force in the development of Islamic science and civilization. Arabic in the future is predicted to play a more optimal role if Islamic educational institutions can synergize with power in establishing its role as a language of diplomacy, language of education, and language of communication in various fields especially in the Islamic economy field.

Published: March 2023

Mutih fasting is a tradition for the bride before the wedding ceremony in Purwokerto, Pati village, Central Java. This study aimed to describe the implementation and meaning of mutih fasting undertaken by prospective brides and determine the value of mutih fasting spiritual education for the brides. This qualitative descriptive study was conducted from August to December 2021. Data were collected by using observation and interviews. The obtained data were analyzed using the phenomenology approach. The results showed that mutih fasting allowed them to get closer to Allah. For prospective brides, fasting was interpreted as an inner preparation by cleansing the heart and soul to achieve wedding success and blessings. Physically, it was interpreted as an effort to suppress appetite so that the bride looked more beautiful, and their aura radiated. Another finding showed that spiritual education was a process of self-purification (Takhalli) for the bride, adorning themselves with noble character (Tahalli), and feeling togetherness with Allah (Tajalli). After this tirakat, it was hoped that the bride had physical and spiritual readiness to enter domestic life, became a pious wife with a clean soul, behaved well and wisely, and received God's protection and help.

Published: March 2023

Background/Aim: Patients who have undergone brain surgery are at risk of falling. Fear of falling causes an increase in the risk of falling and a decrease in movement and daily life activities. However, no previous research has investigated the fear of falling experienced by patients who have undergone brain surgery or the factors that affect it. This study aims to examine the relationship between fear of falling and pain, cognitive status, functional mobility, anxiety, depression, and socio-demographic and clinical characteristics in patients who have undergone brain surgery.
Methods: This cross-sectional study included 115 patients who had undergone brain surgery. The data were collected via a Patient Information Form, the Fear of Falling Scale, the Visual Analogue Scale, the Mini-Mental State Examination, the Itaki Fall Risk Scale, the Hospital Anxiety and Depression Scale, the Glasgow Coma Scale and the Timed Up and Go Test. IBM SPSS 22.0 software was used for descriptive statistics, correlation, and stepwise multiple linear regression analyses.
Results: Of the 115 patients, 73.1% were afraid of falling. Multiple linear regression analysis of the fear of falling in patients who had undergone brain surgery reveals that age (β=0.217, P=0.004), number of postoperative mobilizations (β=-0.141, P=0.031), a reported history of falling (β=0.155, P=0.032), the Timed Up and Go Test (β=0.372, P<0.001), and anxiety (β=0.358, P<0.001) were significant predictors of fear of falling. These variables explained 63% of the common variance.
Conclusion: Age, number of mobilizations, falling experience, functional mobility, and anxiety level can affect the fear of falling in patients after brain surgery. To mitigate this fear, it is important to plan care with reference to these variables from the time of the brain surgery until the patient is discharged. In addition, there is a need for further studies on falling and the fear of falling after brain surgery.

Kuraklık stresi, abiyotik stres faktörleri arasında bitkileri en fazla etkileyen stres faktörlerden biridir. Denemede kuraklık stresi altındaki farklı domates (Kamenta F1 sanayi domates çeşidi ve yerli domates genotipi Fereng) bitkilerine K2SO4, KNO3 ve KCI gübrelerinin yapraktan uygulanmasının bitkilerde yapraklardaki makro (potasyum, kalsiyum ve magnezyum) ve mikro (demir, bakır, çinko ve mangan) mineral besin element ve antioksidan (toplam şeker, fenolik ve flavonoid) içeriklerine etkisi araştırılmıştır. Deneme Nisan-Ağustos 2020 yetiştirme mevsiminde Şırnak’ın İdil ilçesi Çığır köyünde açık tarla koşullarında üretici arazisinde yapılmıştır. Araştırmada 3 farklı %100 (kontrol), %66 ve %33 sulama seviyesi uygulanmıştır. Gübre olarak da yapraktan %1 oranında K2SO4, KNO3 ve KCI verilmiştir. Deneme sonucunda kuraklık stresinin her iki domates çeşidinde de yapraktaki K, Ca, Mg, Fe ve Cu içeriklerinde azaltmaya neden olduğu ancak uygulanan potasyumlu gübrelerin incelenen makro ve mikro besin element içeriklerin iyileştirme yaptığı görülmüştür. %100 sulama uygulamasına göre %33 sulama koşullarındaki bitkilerde toplam şeker içeriğinde, toplam fenolik ve flavonoid madde içerik miktarında en iyi sonuçlar elde edilmiştir. %33 ve %66 sulama altındaki bitkilerde Mn ve Zn içeriklerinde kontrole kıyasla artmıştır. Sonuç olarak KNO3 uygulamasının K2SO4 ve KCI uygulamalarına göre yapraklardaki makro ve mikro besin mineral element içeriklerinde daha etkili olduğu belirlenmiştir.

Authors: OZTURK Murat , ENDES Ali
Published: March 2023

In 2021, post-harvest soil samples were taken from fields where chickpea and wheat were grown in Yozgat province to isolate bacteria. Of 74 isolates obtained from soil samples, 14 nonpathogenic isolates were evaluated for their inhibitory potential against two pathogenic isolates (YBUFoc9 and YBUFoc2) of Fusarium wilt disease agent Fusarium oxysporum f. sp. ciceris. Antagonistic bacterial isolates were identified as Bacillus spp. by Blastn analysis based on their 16S rDNA nucleotide sequences. Among them, 2 isolates were identified as B. amyloliquefaciens (BM23 and BM40), 3 isolates as B. subtilis (BM8, BM32, and BM105), 6 isolates as B. cereus (BM10, BM69, BM70, BM104, BM111 and BM215), 2 isolates as B. megaterium (BM44 and BM135) and 1 isolate as B. pumilus (BM28). No effective isolate of any genus other than Bacillus spp. was found. They inhibited mycelial growth of isolates YBUFoc9 and YBUFoc2 from 0 to 78.50% and from 0 to 58.33%, respectively. Among the 5 different species, B. amyloliquefaciens (BM23 and BM40) and B. subtilis (BM8, BM32, and BM105) showed the strongest inhibitory activity against the two fungal isolates under in vitro conditions. In further studies, the biocontrol properties of the most effective isolates (BM23, BM40, BM8, BM32 and BM105) will be investigated and compared with approved fungicides for their fungicidal activity.

Comparative study: PSC- Gross Split and PSC - Cost Recovery's net contractor share. Should the government of Indonesia gives more Incentives?
Authors: Tiresnofa I.
Published: March 2023

The amendments of existing PSC policies were made to adapt with the current situation and done comprehensively in term of economic, social, political, and security perspectives. These amendments were expected to increase the attractiveness of the PSC mechanism to Contractors to attract new investment. The Indonesian government has been using PSC-Cost Recovery since 1971. 4 generations of Modifications to the PSC-Cost Recovery have been made. In 2017 (4th generation), the government modified the PSC-Cost Recovery to PSC-Gross Split. This modification is intended to level up the attractiveness of upstream oil and gas investment climate in Indonesia by increasing the share of PSC-Gross Split contractors compare to PSC-Cost Recovery. This study aims to calculate whether the contractor’s share of the PSC-Gross Split is higher than the PSC-Cost Recovery. The definition of the contractor share in this research is Net Contractor’s Income for PSC-Gross Split and Net Contractor Take for PSC-Cost Recovery. Descriptive statistic shows that, during observation period (2015-2020) for 14 working areas, the average Contractor Net Income for PSC-Gross Split (-1,78%) is lower than average Net Contractor Take for PSC-Cost Recovery (9,47%). However, by using the Welch test, the result indicates that there are no statistical differences (α = 10%) between the Net Contractor’s Income (PSC-Gross Split) and Net Contractor Share (PSC-Cost Recovery). In short, the modification to PSC-Gross Split has not been able to improve the contractor’s share as projected. Therefore, the author recommends the Government of Indonesia to escalate incentive to elevate the share of contractors, at least similar with PSC-Cost Recovery.
The Performance of Oil and Gas Lifting Operation and The Stock Draining in Achieving The National Production Target
Authors: Prasetya A.E
Published: March 2023

Oil and gas lifting is a key performance indicator for SKK Migas. Oil and gas lifting shall mean the amount of oil and/or gas production which has been sold/distributed. Lifting is assessed based on the achievement of targets that have been determined by the government through the state revenue and expenditure budget (APBN) or on technical figures that are evaluated and agreed upon in the work plan and budget (WP&B). During the period of 2016-2020, observations were made on the performance of Indonesia's oil and gas lifting and the draining of oil tank stocks at the end of each year. At a regional level, the South Sumatera Region has a number of custody transfer points and monitoring points for oil and gas lifting spread across three provinces. This paper also discusses what has been done in the area to improve the performance of lifting operations and reducing dead stock. The lifting supervision method refers to the knowledge of the quantity accounting system (QAS), application of procedures and the use of appropriate instruments. Several changes were made to the lifting supervision strategy starting in 2018. The competence of personnel is strengthened by training and field introductions. The lifting supervisory organization was formed with the setup of regional representative offices in order to improve access to information. The officers supervise the compliance with lifting procedures. Lifting supervisors coordinate with PSC Contractors through shipping coordination (shipcoord), oil distribution operations coordination (KOPM), and gas coordination meeting (GCM). Engagement to field implementer and surveyors is carried out for the accuracy of the lifting equipment and figures. The work schedule of field supervisors is optimized accordingly. Several adjustments in lifting operation were made as a response to the COVID-19 pandemic in order to maintain lifting performance. During the period of 2016-2020, the average performance of Indonesia's oil and gas lifting was 99% of production, followed by a significantly decline in year-end stock levels by an average of 53%. The realization of the lifting figure in the South Sumatra region is 100% of the nomination figure. The South Sumatra region contributes 10% of the national lifting. Lifting supervision carried out according to procedures and supported by good cooperation between the parties, will achieve the lifting operation performance target as expected. This paper provides a fairly complete picture of how lifting operations are carried out and how much lifting supervision has an effect on increasing lifting performance. This paper is also expected to contribute knowledge that can be utilized by lifting supervisors.
Application of Relative Permeability Modifier for Fluid Loss Control During TCP Shoot & Pull to Improve Rig Efficiency - Offshore Indonesia
Authors: Pratama A.
Published: March 2023

Five wells were drilled to produce gas from a sandstone formation with gross intervals of 314-696 ft. The operator required underbalanced perforating to improve perforation clean-up and avoid formation damage from the wellbore fluid. Underbalance (UB) perforating was carried out in previous campaigns with a modular gun system conveyed on wireline, allowing the perforation guns to be dropped into the rat-hole after firing. However, this technique couldn't be implemented for these cases due to a high deviation angle and limited rat-hole length. Several options were available, such as the Coiled Tubing (CT) live-well deployment system and modular gun with detaching system. However, these options increase the risk and rig time requirements. Therefore, Tubing Conveyed Perforating (TCP) shoot and pull was selected as the primary technique with the risk of formation damage during well kill operation. To minimize formation damage, a Relative Permeability Modifier (RPM) was pumped to reduce fluid loss and allow the well to be killed with minimal or no damage. RPM was selected as it is a solids-free fluid compatible with the formation that doesn't require a post-clean-up operation, potentially saving 2-3 days of rig-time. The TCP gun was run with a circulation sub, allowing oil-based fluid to be pumped above the circulating valve to create a 600 psi underbalance on the first well while the rest of the wells were perforated overbalanced. Once the TCP gun was fired, oil-based fluid was circulated with the brine, and RPM was placed into the formation to create a +/-300 psi overbalance condition. Once the well was killed, the TCP gun was pulled safely to surface. The RPM successfully reduced fluid loss in all five wells, where the highest static loss rate encountered after perforating was 160 bbl/hr, which was reduced to 7 bbl/hr after the RPM was pumped.
