Abstract
Exploration well with carbonate reservoir is a challenging well to plan for due to risk of total losses because of karst presence. It became even more challenging for a subsea well with high bottom hole temperature (BHT) and prospect of well testing. Flow of HT reservoir fluids (BHT up to 175 deg C) to surface will resulted in significant heat transfer to adjacent casing & its annulus fluids, and lead to annular pressure build-up (APB). High APB will lead to loss of well integrity via 13-3/8" intermediate casing burst and 9-7/8" production casing collapse if left unmitigated. As per The Company technical standards, two APB mitigations were required in a subsea well. The first selected mitigation is an open casing shoe. The exposed shoe will act as a natural relief valve whenever APB exceeding its fracture pressure (FP), therefore, limit the APB to its FP. However, it is challenging to keep the 9-7/8" casing top of cement (TOC) below the 13-3/8" casing shoe and fulfil the open shoe barrier requirement for this well where the open hole interval is relatively short and subject to be plugged off by barite sagging, insufficient open shoe length for safety margin of excess cement and requirement of minimum annulus cement length for shoe integrity. Extra mitigations were addressed through extensive lab tested solids-free annulus fluid to mitigate barite sagging. Open shoe interval also designed with multiple weak sands exposure and higher FP were considered for worst-case APB simulation. The second barrier is the 13-3/8" intermediate casing and 9-7/8" production casing itself. Based on WellCAT simulation, the intermediate casing unable to meet The Company standards of burst (safety factor, SF &lt; 1.1) in the worst-case scenario whereby APB is unmitigated. The casing burst pressure rating was recalculated using API Bulletin 5C3 equation with the inputs taken from minimum actual casing wall thickness measurement and internal yield pressure from its mill certificate. Technical derogations were raised and approved once the casing passed all the load cases using the revised burst rating by minimum SF of 1.0. The well was delivered successfully with the open hole barrier for both casing was executed flawlessly despite the complex fluid train while cementing.
Treatment and Prevention of Stuck Pipe Based on Artificial Neural Networks Analysis

Published: March 2022

Abstract
Oil and gas drilling is a field practice with risks and uncertainties. Uncertainty and ambiguity of formation conditions often cause downhole accidents such as borehole wall instability, stuck drilling, blowout, etc., and also pose a threat to drilling safety.Due to the incorrect understanding of the objective environment and the wrong decision of subjective consciousness; it caused complex underground conditions and serious accidents.
Collapse stuck is the worst kind of accident in stuck stuck. The procedures to deal with this kind of accident are the most complicated, the most time-consuming, the most risky, and even the whole or part of the wellbore may be scrapped, so we should try our best to avoid this accident during the drilling process.Artificial Neural Networks (ANNs for short) is a mathematical model of algorithms that imitate the behavioral characteristics of animal neural networks and perform distributed parallel information processing.
This kind of network depends on the complexity of the system and adjusts the interconnection relationship between a large numbers of internal nodes to achieve the purpose of processing information, and has the ability of self-learning and self-adaptation.
This paper analyzes the causes of collapse stuck, the mechanical mechanism of drilling fluid wettability on the stability of mud shale formation wall.A surface wetting reversal agent added to the drilling fluid system was used to change the wettability of the shale surface.The mechanism analysis and research results of changing the wettability to change the mechanical properties of the shale fracture surface were applied to the actual production of the collapsed drilling rig.Through the change of drilling parameters, the risk of stuck drilling is predicted in advance, the drilling speed is increased, the drilling time loss caused by stuck drilling is reduced, and the drilling cycle and cost are saved.

Authors: Aye Abalaka A. , Agida Teddy E. , Babalola Akinola A. , Isah Aliyu Y. , Adewole Nathaniel David 
Published: March 2022

Background:
Ultrasound measurement provides a noninvasive means of obtaining information about fetal weight and may help in necessary preparations at and after delivery. Although some ultrasound methods include only one or two fetal indices, others, to improve accuracy, incorporate either three or all the four fetal indices. The aim of this report is to assess the accuracy of two different methods for fetal weight estimation.

Materials and Methods:
This was a prospective study of 170 consecutive pregnant women at term. Ultrasound was used to estimate fetal weight by the Shepard and Hadlock methods, and the actual birth weight (ABW) was determined at birth. The ultrasound-estimated fetal weights (EFWs) and ABW were analyzed.

Results:
The women were aged 21–42 years (mean 31.3 ± 7 years). The EFW using the Shepard method was 1.9 kg–5.0 kg (mean 3.6 ± 0.5 kg) and 1.8 kg–4.4 kg (mean 3.3 ± 0.4 kg) for Hadlock method, and ABW was 2.0 kg–4.5 kg (mean 3.4 ± 0.5 kg). The mean EFW using the Shepard method was significantly higher than that of ABW (P < 0.001). The Shepard method significantly overestimated macrosomia compared to that by the ABW. There was no significant difference in microsomia rate between the two methods and ABW.

Conclusion:
The Hadlock method was more accurate at estimating fetal weight compared to the Shepard method and is recommended for the ultrasound estimation of fetal weight in our setting and similar settings.

Authors: Jawahar Anusha , Krishnamurthy Vishwanath , Kulkarni Ashwin , Kumar T. Anil 
Published: March 2022

ABSTRACT

Background:
Metabolic syndrome (MetS) refers to a group of conditions that are associated with increased cardiovascular risk. Ankle–brachial index (ABI) is a noninvasive, inexpensive way of assessing the blood flow in the lower limbs and may be useful as an indirect marker of subclinical atherosclerosis.

Aim and Objective:
To study and compare ABI values between patients with MetS and patients without MetS.

Materials and Methods:
A total of 98 patients attending the outpatient department between October 2018 and September 2020 were included in the study. They were categorized as MetS and non-MetS as per the National Cholesterol Education Program Adult Treatment Panel III guidelines. They were tested for ABI with a handheld Doppler. The ABI values were compared between the two groups.

Results:
Among 98 patients, 49 were cases and 49 as controls. ABI values were found to be 1.09 ± 0.12 among the cases and 1.22 ± 0.05 among the controls and were found to be statistically significant (P < 0.001).

Conclusion:
The patients with MetS had lower ABI compared with the patients who did not have MetS. ABI can be used as an indirect marker of atherosclerosis and can be used in routine clinical assessment for identifying patients at a higher cardiovascular risk.
Optic nerve ultrasound and cardiopulmonary bypass
Authors: Wakimoto Mayuko , Patrick Joseph H. , Yamaguchi Yoshikazu , Roth Catherine , Corridore Marco , Tobias Joseph D. 
Published: March 2022

Introduction:
Despite advances in surgical, anesthetic, perfusion, and postoperative care, adverse neurological consequences may occur following cardiac surgery and cardiopulmonary bypass (CPB). Consequences of the physiologic effects of CPB may alter the blood–brain barrier, autoregulation, and intracranial pressure (ICP) in the immediate postoperative period.

Methods:
We evaluated the effects of cardiac surgery and CPB on the central nervous system by measuring the optic nerve sheath diameter (ONSD) by using ultrasound as a surrogate marker of ICP. ONSD was measured after anesthetic induction and endotracheal intubation (time 1), after separation from CPB (time 2), and at the completion of the surgical procedure prior to leaving the OR (time 3).

Results:
The study cohort included 14 patients, ranging in age from newborn to 6 years. When comparing the Fontan group (n = 5) to the non-Fontan group (n = 9), four elevated ONSD observations were recorded for the Fontan patients during the study period, including one at time 1, one at time 2, and two at time 3. In Fontan versus non-Fontan patients, ONSD was greater at all three time points compared to non-Fontan. The change in the ONSD from time 1 to time 2 was greater (+0.2 mm vs. −0.1 mm), and the mean value at time 2 was significantly higher (4.2 vs. 3.5 mm, P = 0.048).

Conclusions:
Patients with Fontan physiology may be more prone to higher levels of baseline intracranial pressure due to elevated systemic venous pressure and decreased cardiac output. Alternatively, the chronically high central venous pressures may artificially elevate ONSD without clinical changes in ICP, necessitating the development of separate normative values based on the type of congenital heart disease.

Authors: Bahaziq Wadeeah , Hassan Ahmed R. , Jubili Majd Y. , Boker Abdulaziz 
Published: March 2022

Purpose:
Walker-Warburg syndrome is a rare autosomal recessive congenital muscular dystrophy presenting with hydrocephalus, type II lissencephaly, cerebellar malformation, and ocular anomalies. Here, we describe the use of perioperative total intravenous anesthesia in a pediatric patient with Walker-Walburg syndrome.

Clinical Features:
A 2-month-old girl with Walker-Walburg syndrome was admitted for urgent ventriculoperitoneal shunt insertion. Anesthesia was induced using intravenous atropine (100 μg), ketamine (10 mg), and fentanyl (15 μg). The patient was monitored for various clinical parameters based on American Society of Anesthesiologists standards. Anesthesia was maintained using intermittent doses of 0.5 mg intravenous midazolam and 5–10 μg fentanyl in incremental boluses. The postoperative course was uneventful.

Conclusions:
To our knowledge, no published cases have reported the use of total intravenous anesthesia in patients with Walker-Walburg syndrome who have potential risks for anesthetic-induced malignant hyperthermia. This report described the key features, potential anesthetic management plan, and current literature review of Walker-Walburg syndrome.
Comparison of the effectiveness of intravenous fentanyl versus caudal epidural in neonates undergoing tracheoesophageal fistula surgeries
Authors: Nagappa Saraswathi , Kalappa Sandhya , Vijayakumar H N , Nethra H N 
Published: March 2022

Background:
Caudal epidural has become an inseparable part of pediatric pain relief as it depresses the stress response better than any other form of analgesia, resulting in the reduction in the need for systemic opioids; in addition, it facilitates early recovery and promotes good postoperative respiratory functions.

Aim:
To evaluate the effectiveness of epidural analgesia in neonates undergoing tracheoesophageal fistula repair in terms of requirement of perioperative fentanyl opioid, postoperative neonatal infant pain score (NIPS), on-table extubation, duration of intubation, reintubation, perioperative hemodynamic response, and any other side effects.

Materials and Methods:
A comparative, prospective, single-blind, randomized trial on 30 neonates scheduled for tracheoesophageal surgeries were randomly allocated to two groups: group I: neonates receiving caudal epidural block with ropivacaine 0.2%, 1 mg/kg bolus followed by infusion 0.1 mg/kg/h; group II: neonates receiving initial intravenous [IV] fentanyl 1 ug/kg and maintenance with 0.5 μg/kg/h IV bolus.

Results:
None of the neonates received opioids in group I. There were statistically significant differences in the mean NIPS at 30, 60, 90, 120 150, and 240-min intervals between group I and group II. Further, 80% of neonates were extubated in group 1 compared to 50% in group II, which was statistically significant (P = 0.025). The duration of intubation was more in group II compared to group I, with a suggestive significance of P = 0.093.

Conclusion:
Caudal epidural infusion provides adequate perioperative analgesia, promotes rapid weaning from the ventilator, and contributes to a successful outcome.

Simenon et Kierkegaard, inspirateurs de La Promesse
Authors: Barilier Étienne 
Published: March 2022

La donnée initiale de La Promesse est directement empruntée à Maigret tend un piège de Simenon. Mais cette histoire de piège cache une idée de sacrifice, chez Simenon lui-même, et bien plus encore chez Dürrenmatt. La Promesse apparaît alors comme une variation sur le récit du sacrifice d’Isaac tel que l’interprète Kierkegaard dans Crainte et tremblement. Le cœur de la méditation du philosophe danois, comme de la fiction de l’écrivain suisse, c’est l’absurde, qui pour Kierkegaard est salvateur, et donne son sens suprême au geste d’Abraham, alors qu’il est pour Dürrenmatt le non-sens même, vouant l’homme à craindre et trembler sans espoir d’apaisement.

Development of a Statistical Reliability-Based Model for the Estimation and Optimization of a Spur Gear System
Authors: Aikhuele Daniel 
Published: March 2022

In this paper, a statistical model which is based on the stress-strength theorem, has been proposed for the estimation and optimization of spur gear systems embedded (running) in a mechanical device. First the model is used for the estimation of the variation of the bending stress and the contact pressure distribution in the spur gear systems, which several studies have confirm as the main source of failure (failure modes) in the spur gear system. The optimal variation values of the stress and strength distribution as well as the reliability of the spur gear systems are then determined, via a statistical reliability analysis method embedded in model, which is otherwise refers to as the proactive approach. The proactive approach is apply mainly to evaluate and predict the system failures. The computational results from the analysis shows that, the higher the stress distribution function, the lower the reliability of the spur gear system. Also, with a distributed strength functions of 696.3MPa and a mean value of 100MPa of the spur gear system, the optimal stress values is between the range 0 to 369.5MPa.
