An improved method for determining oil saturation by chlorine hydrogen ratio based on neutron self-shielding correction

A method is proposed to use iron's captured gamma rays to mark the neutron self-shielding correction factor and combine it with the chlorine to hydrogen ratio to determine the oil saturation. The Monte Carlo method is used to establish a wellbore-formation model to simulate different porosity and formation water salinity. Captured gamma energy spectrum under conditions, studied the neutron self-shielding factor and oil saturation logging response, and verified the method through simulation examples. The results show that: the chlorine-to-hydrogen ratio after iron-labeled neutron self-sh

Difference, origin and oil source significance of tricyclic terpenes in Chang 7 source rocks in Ordos Basin

In recent years, a large amount of industrial oil and gas resources have been discovered in the Paleogene Wenchang Formation (WC) of the southern Lufeng sag, confirming that the WC resources are promising prospects for petroleum exploration. However, because of the complex lithology, multiple sources of crude oil and multi-period charging characteristics in the WC, the accumulation process and model have not been clearly understood. Therefore, in this study, the main sources of crude oil and the process of hydrocarbon accumulation in key oil accumulation periods are determined by combining

Car Crowd Management using Proposed YOLOv5 Model

Car crowd management refers to the process of efficiently and safely managing the movement and flow of cars in crowded areas, such as parking lots, traffic intersections, event venues, and busy streets. Effective car crowd management is essential to ensure smooth traffic flow, prevent accidents, reduce congestion, and optimize the utilization of available parking spaces. It is a critical aspect of urban planning and traffic management to enhance the overall transportation experience and safety for both drivers and pedestrians. In this paper, a system was proposed for managing car crowds at tra

Numerical algorithm for searching the optimal temperature regime of a chemical process based on the method of artificial immune systems

The paper presents an algorithm for calculating the optimal temperature regime of a chemical process in the presence of terminal constraints. The formulation of the problem of optimal control of a chemical process is given, in which constraints on the control parameter and phase variables are given. A method of solving this problem based on the penalty method and artificial immune systems is given. The penalty method allows to reduce the problem with terminal constraints to the problem without constraints by changing the optimality criterion. The new optimal control problem without terminal co

Production of High Cetane Number Biodiesel from Jatropha Curcas L. Seed Oil: Improvement of Physicochemical Characteristics

Finding out how the trans-esterification process influences the chemical make-up and fuel quality of biodiesel made from Jatropha curcas L. seed oil is the main objective of this work. The extracted Jatropha oil was characterized by GC-MS and ICP technique and American Oil Chemist Society standards were used to study its physicochemical properties. Due to the fact that every physicochemical property does not meet WHO specifications, it has been determined to be non-edible oil; these findings demonstrate that the high oil content (30 %) and free fatty acid composition of Jatropha seed oil make
