/in /by

Enhanced oil recovery (EOR) techniques are important for increasing oil production as to meet global energy demands. Surfactant flooding is a commonly used EOR method, but it has issues with surfactant molecules adhering on the surface of the reservoir rock more especially at higher salinity range. The study compares the effect of Sodium Dodecyl Sulfate (SDS) surfactant and Aluminum oxide (Al2O3) nanoparticle hybrid at different salinity concentration ratios, stand-alone Sodium Dodecyl Sulfate surfactant and Aluminum oxide nanoparticle on viscosity, salinity ranges of 30,000ppm and 60,000ppm, permeability change and oil recovery. The efficiency of the formulated fluids was tested through flooding experiment using different twelve core samples of Niger – Delta sand formation. The results showed that the surfactant-nanoparticle hybrid solution enhanced the viscosity of fluids, gave better permeability change and higher oil recovery for both 30,000ppm and 60,000ppm salinity change examined. Concentration ratio of 0.1 wt%Al2O3 and 0.3wt% SDS gave the highest cumulative oil recovery of 82.61% using 30,000 ppm and 78.26% for 60,000ppm brine concentration at the same fluid concentration ratio brine followed by 0.2 wt%Al2O3/0.3wt%SDS concentration ratio. The hybrid with 0.1 wt%Al2O3 and 0.3wt% SDS concentration ratio gave lower permeability change of 52.30md than every other concentration investigated. The combination of Aluminum oxide nanoparticle and Sodium Dodecyl Sulfate surfactant enhances surfactant properties as to improve displacement efficiency, reduce surfactant adsorption and permeability damage.

Clinical Insights into Narrow Therapeutic Index Drugs

/in /by

Medications with a narrow therapeutic index (NTI), such as phenytoin, warfarin, and vancomycin, require precise dosing to avoid adverse effects and ensure they remain effective. This is particularly important for at-risk groups like elderly individuals or those with multiple health conditions. The therapeutic index (TI) is a key measurement that indicates the range between a drug’s therapeutic and toxic levels. NTI drugs need careful management because even small changes in their concentration can lead to significant risks and impact their therapeutic benefits. Factors unique to each patient, such as age, existing health conditions, and genetic differences, can affect how NTI drugs are metabolized and their overall effectiveness. As a result, therapeutic drug monitoring (TDM) is crucial for tailoring dosing strategies and minimizing the risk of harm. Interactions between NTI drugs and other medications, especially those that involve cytochrome P450 enzymes, can influence drug concentrations, making treatment more complex. The growing field of personalized medicine, which includes pharmacogenomics, aims to improve outcomes by customizing drug therapies based on individual genetic characteristics. Proper management of NTI drugs requires teamwork among healthcare professionals, including doctors, pharmacists, and nurses. Continued research, along with advancements in drug delivery systems and artificial intelligence, holds potential to enhance the safety and effectiveness of NTI medications.
