Tubular String Characterization in High Temperature High Pressure Oil and Gas Wells

Tubular String Characterization in High Temperature High Pressure Oil and Gas Wells

High temperature high oil pressure oil and gas well completion testing have always been a technical challenge and basic theoretical research is one of the key factors needed to ensure a successful completion test. The completion test basic theory includes: a stress analysis of the completion string completion string buckling behavior and temperature and pressure distribution prediction. The completion string is the main bearing and power transmission component for oil and gas well operations and production and it is required to take on a combination of loads which result in completion string deformation. Because of these complex relationships completion string stress analysis has become increasingly more complicated. This book discusses the characters of tubular strings in HTHP (High Temperature - High Pressure) oil and gas wells. These characters include the mechanical behavior of tubular strings and the temperature and pressure variation of tubular strings in different conditions. Mathematical models are established for different conditions and solution existence and uniqueness of some models is discussed providing algorithms corresponding to the different models. Numerical experiments are presented to verify the validity of models and the feasibility of algorithms and the impact of the parameters of models for oil and gas wells is also discussed. This book is written for production and testing engineers to provide them with the tools to deal more effectively with the numerical decisions they have to take and for researchers and technicians in petroleum and gas testing and production engineering. Finally it is also intended to serve as a reference book for mathematicians college teachers and students. | Tubular String Characterization in High Temperature High Pressure Oil and Gas Wells

Essential Oils as Antimicrobial Agents in Food Preservation

Essential Oils as Antimicrobial Agents in Food Preservation

Perishable products such as fruits and vegetables account for the largest proportion of food loss due to their short shelf life especially in the absence of proper storage facilities which requires sustainable universal and convenient preservation technology. The existing methods to prolong the shelf life of food mainly include adding preservatives irradiation cold storage heat treatment and controlled atmosphere storage. But with disadvantages in irradiation cold storage heat treatment and controlled atmosphere storage chemical synthetic preservatives are still the main means to control food corruption. As the food industry responds to the increasing consumer demand for green safe and sustainable products it is reformulating new products to replace chemical synthetic food additives. Essential Oils as Antimicrobial Agents in Food Preservation provides a comprehensive introduction to the antimicrobial activity of plant essential oils and their application strategies in food preservation. It is aimed at food microbiology experts food preservation experts food safety experts food technicians and students. Features: Summarizes the application strategy and safety of essential oil in the field of food preservation Describes the synergistic antibacterial effect of essential oil and antimicrobial agents Explains the action mechanism of essential oil as antimicrobial agent against foodborne fungi foodborne bacteria viruses and insects Analyzes the antimicrobial activity of essential oil in gas phase The book discusses how as a natural antimicrobial and antioxidant essential oil has great potential to be used in the food industry to combat the growth of foodborne pathogens and spoilage microorganisms. But because the essential oil itself has obvious smell and is sensitive to light and heat it cannot be directly added to the food matrix and thus the application strategies presented in this book explain how to alleviate those issues.
