Published: March 2024

Surge and swab pressures are frequently produced during various stages of well construction, including casing running and tripping operations. Managing downhole pressure within the mud window is crucial for mitigating the risks associated with drilling operations including wellbore failure, lost circulation, kicks, and well control issues. The primary objectives of this study are to emphasize the theoretical foundation of surge and swab pressures, forecast the optimum pipe and casing tripping speeds, as well as identify the changes in surge and swab pressures (i.e., equivalent circulating density-ECD) for both open-ended and close-ended drill strings. To achieve these goals, a steady state surge and swab model was used to simulate a case study in the Rumaila oil field, located in Southern Iraq, by utilizing landmark-well plan software. The results of this study support the evidence that the string trip speed plays a substantial role in controlling the swab and surge pressures. It was found that pulling out the 5" drill string from the 12 1/4" open hole section drilled with a 9.51 ppg water-based mud at a speed of 10 sec/stand resulted in a swab ECD below the formation pore pressure against all formations, thus resulting in a kick. Moreover, it was found that the annular clearance had a significant impact on the surge and swab ECD whereas the surge ECD at the bit was bigger than that obtained at the previous hole casing shoe. For example, in our case study pulling speeds ranging from 10-190 sec/stand for the 9 5/8" casing could cause the swab ECD to be below the formation pore pressure gradient at total depth (TD), which is 9.23 ppg. While it was safe to run the same casing through the same interval within 55-190 sec/stand. Furthermore, the results emphasized high trip speeds ranging between 10-30 sec/stand, where for close-ended drill strings, greater surge ECD was observed compared to the open-ended ones. The surge ECD of a 5" close-ended drill string at 30 sec/stand (60 m/min) at bit was 9.92 ppg, while an open-ended string at the same speed was 9.9 ppg.
Maximizing Production Profits: Optimizing Gas Lift Design in the Halfaya Oil Field
Authors: Ahmed Safwan Riyadh , Sadeq Dhifaf Jaafar 
Published: March 2024

Gas lift is one of the most common artificial lift methods which is effectively utilized in the oil industry for enhancing production. However, proper gas allocation into wells can be challenging due to various limitations such as shortage in injected gas and economic considerations. Therefore, the current research is conducted to address the critical requirement to effectively distribute gas to maximize profits in the Halfaya Oil Field- Mishrif formation. Continuous gas lift is one of the most commonly used artificial lift methods. To enhance production rate, a sufficient amount of gas is injected into the production tubing at specific depths to reduce the liquid column pressure as each well has an optimal point for production in an oil reservoir. On the other hand, constraints of gas availability restrict achieving the optimal state of production. Such restrictions combined with economic limitations including high gas prices and compression costs, emphasized the necessity for optimal methodology to enhance oil production. Aside from the importance of the Halfaya oil field, there are limited relevant studies on artificial lifting methods specifically associated with the gas-lifting method used in this paper. Thus, the purpose of the current investigation is to propose a well-tested gas lifting design for oil production improvement. The approach combines the skill of the fmincon function built in MATLAB as an optimizer and the PIPESIM network model to create gas lift performance curves. This resulted in an oil production rate of 18860 STB/d, with a gas lift rate of 9.42 mmscf/d. Establishing such a systematic optimization process can manage the challenges of gas allocation in the Halfaya Oil Field towards maximizing production rates and ultimately increasing net profits.

Published: March 2024

The scarcity of fresh water and its essential role in sustaining life on Earth have motivated researchers to seek new, low-cost, scalable technologies for water desalination. Therefore, the osmotically assisted reverse osmosis (OARO) membrane process presents an innovative approach to achieve moderate water recoveries from high salinity water without undergoing a phase change. This work aims to investigate the performance of hybrid RO-OARO systems with various designs and operational parameters on recovery and R%. The hybrid systems were evaluated for 60 minutes at feed concentrations of 3.98-5.54 g/l, applied pressures ranging from 3 to 7 bars, and different membrane types. The results showed that the flux of the hybrid system increased by increasing the pressure and decreased by increasing the feed concentration. The highest recovery value was obtained for the RO-OARO system at an RO pressure of 7 bar and an OARO unit at 3 bar for a 3.98 g/l feed concentration. In contrast, when the reverse osmosis pressure was fixed at 5 bar, and the pressure of the OARO unit increased by 2 bar, the recovery value exceeded by about 6%. Furthermore, the FilmTech membrane showed the highest recovery at 31.7%, while the highest R% was 94.55% for the AquaTec membrane. The RO-OARO-OARO system contributed to increasing both the recovery and rejection values by 11.4 and 2.1%, respectively, compared with the RO-OARO system. The experiments in this study revealed a slight increase in the feed concentration of the reverse osmosis unit, indicating the efficiency of the hybrid systems compared to traditional RO systems.

Published: March 2024

Coffee is the most essential drink today, aside from water, the high consumption of coffee and the byproducts of its soluble industries such as spent coffee grounds can have a negative effect on the environment as a source of toxic organic compounds. Therefore, caffeine removal from the spent coffee ground can be applied as a method to limit the effect of its production on the environment. The aim of this study is to determine the kinetics and thermodynamics parameters and develop models for both processes based on the process parameters by using traditional solid-liquid extraction and Ultrasound-assisted extraction methods. The processes were performed at a temperature range of 25 to 55 °C for traditional and ultrasound baths, and experimental time ranged from 5- 60 min. The results demonstrated that under the above conditions, the extraction process applies to the pseudo-first-order reaction, where the rate constant K value increases with temperature. The transition state parameters were also discussed where these parameters indicated that the system of the process exhibited an activated complex formation state resulting in a thermodynamically unfavorable process, and the thermodynamic parameters at the equilibrium state were also evaluated in terms of the obtained yield percentage. The results also showed that the ultrasound-assisted bath process showed a spontaneous behavior at temperatures of 45 °C and 55 °C with D°G of -1192.9703 and - 2725.25 J/mole. On the other hand, for the traditional method, the extraction process was approaching a spontaneous behavior with the temperature increasing where at 25 °C the D°G value was 10379.944 J and at a temperature of 55 °C it reached 8004.26 J/mole.
Перспективи комплексного освоєння буровугільних родовищ Закарпаття як джерела отримання критичної мінеральної сировини
Authors: Бурлуцький М. С. 
Published: March 2024

Проведено аналіз критичної мінеральної сировини на підставі Звіту Міністерства енергетики США (DOE) “Оцінка критичних матеріалів”, що був виданий в США в липні 2023 р., а також Методології визначення критичної мінеральної сировини в Європейській Раді (2017 р.). В Звіті DOE зазначається, що 2022 р. став рекордним роком впровадження чистих енергетичних технологій. Рекордне поширення технологій чистої енергії, таких як сонячні фотоелектричні установки й акумулятори, сприяють безпрецедентному зростанню критичних ринків корисних копалин. Цей аналіз доповнює визначення критичних корисних копалин Геологічної служби США.В Європі першу доповідь, присвячену критичній сировині, куди було включено 14 мінералів, опублікували ще у 2011 р. Протягом наступних років модернізувалася політика щодо сталого надрокористування всередині Європейського Союзу. У 2017 р. світ побачив першу методологію щодо призначення сировині статусу “критичної”, а в січні 2018 р. – доповідь про перспективи відновлюваної промисловості в ЄС.Логічним завершенням цього процесу стало створення ERMA – промислового альянсу в цій галузі, де сформульовано більш деталізоване визначення “критичної сировини”. Критична сировина в ЄС – це насамперед та сировина, яка є не лише економічно та стратегічно важливою для європейської економіки, але й та, виробництво якої пов’язане з високим ризиком поставок.В статті здійснено порівняння понять критичної сировини в США та Європейському Союзі. На підставі вказаних документів проведено аналіз поточних тенденцій в сфері критичної мінеральної сировини.Варто зазначити, що в Україні поняття “критична мінеральна сировина” або “критичні корисні копалини” до цього часу законодавством не визначено. Між тим, у липні 2021 р. Україна та Європейський Союз уклали Меморандум про стратегічне партнерство щодо сировинних ресурсів.В нашій державі наявні близько 20 критичних корисних копалин, що містяться в переліку, зокрема, критичних для ЄС. Одним з критичних елементів як у США, так і в Європейському Союзі є германій. Наведено властивості, джерела отримання та напрями застосування германію в різних сферах сучасного життя. Проведено аналіз виконаних рініше пошуково-розвідувальних робіт на германій, що вміщують буровугольні родовища Закарпаття. Крім германію, також за результатами здійснених робіт було встановлено, що на родовищах та вуглепроявах заслуговують на увагу також інші рідкісні елементи, такі як галій, берилій, скандій, ітрій, лантан тощо.Проведений аналіз пошуково-розвідувальних робіт на буровугільних родовищах Закарпаття вказує на те, що ці родовища вміщують багато рідкісних, зокрема і рідкісноземельних, металів, які дуже необхідні для економіки України. Великий попит на критичну мінеральну сировину, в тому числі на германій та інші види рідкісних (рідкісноземельних) металів, є підтвердженням необхідності проведення подальших пошуково-розвідувальних робіт на буровугільних родовищах Закарпаття.

Published: March 2024

Background. Ovarian endometriomas account for 35% of all benign ovarian cysts and are identified in 17-44% of women with endometriosis. External genital endometriosis is diagnosed in 10-15% of women in the general population, 25-60% of patients with infertility, 80% of those with pelvic pain syndrome, and in cases of dysmenorrhea, it ranges from 40 to 60%. Priority issues include early diagnosis, management tactics, and preservation of ovarian reserve in women with ovarian endometriomas. However, risk factors contributing to the formation and progression of the disease are nonspecific, and the clinical presentation does not always correspond to the severity of the condition.
Aim. To determine the clinical and anamnestic features of women of reproductive age with ovarian endometriomas.
Materials and methods. A clinical and anamnestic examination was conducted on 120 reproductive-aged patients with ovarian endometriomas (main group) and 30 women without gynecological pathology (control group). The average age of the examined individuals was 29.5±1.3 years. The examination protocol included the assessment of objective and subjective data recorded in a specially designed questionnaire containing 300 questions. Statistical data analysis was performed using the computer program "Statisticа 13.3.721."
