The economic aspects of technological advances in the drilling industry using the maximum reservoir contact (MRC) method compared to other drilling technologies have been investigated in this study. Field and survey methods from combined implementation research methods have been performed by a dynamic approach using Vensim software. Professors, drilling and reservoir engineering professionals in the oil and gas drilling industry, or equivalent positions, comprised the study’s statistical population. Finally, 120 individuals were chosen by nonprobabilistic sampling (judgment) and the snowball method. In the Vensim dynamic environment, the simulation completion time (based on the 2017 dynamics model) and the initial simulation time (based on the 2013 dynamics model) were adjusted to generate a flow diagram analyzing the economic aspects of technological improvements in this type of drilling industry. According to the causal tree results, the drilling industry’s performance has the highest priority among studies of economic aspects of technological changes in the drilling industry using the MRC method. It has a significant relationship with technological changes in the drilling industry. The sensitivity analysis chart demonstrated that with a change in the variable of indicators of the drilling industry at an average level of 5.25 to 5.5, the target variable, i.e., the performance of the drilling industry, had the least sensitivity and had no particular effect on it. On the other hand, by modifying the effectiveness of the drilling industry, effectiveness indicators at the average level of 6.95, the target variable had the maximum sensitivity and had a very significant effect on it.

As a significant consequence of internal and external characteristics in auditors, independence plays a vital role in promoting professional judgment in auditing. This dimension of individual audit functions has always been considered one of the areas studied in this profession due to its integration with the perceptual and often intangible features of auditors’ behavior. Therefore, this study, understanding the importance of independence functions in the auditing profession, seeks to identify the characteristics of inertia as a stimulus for independence in auditing in the petrochemical industry to act on its interpretive ranking. This research is a mixed method due to the nature of data collection. It first uses interviews to identify the characteristics of inertia in the auditing profession and then employs the checklists of the pair scale to determine the interpretive ranking. Accordingly, the grounded theory and the quantitative part are used in the qualitative part, and Delphi analysis and the interpretive ranking process are used. The statistical population in the qualitative section were 12 auditing professionals who, in terms of theoretical knowledge, had the necessary capabilities to develop the concept studied in this study. They were selected through theoretical sampling based on the snowball technique. The statistical population in the quantitative part were 19 auditors with work experience in the petrochemical industry and a level of technical and specialized knowledge; they were selected using homogeneous sampling. The research results in the qualitative part indicate the existence of 3 categories, 8 components, and 35 concept codes that have laid the inertial features in the auditing profession in the form of an 8-dimensional integrated model. On the other hand, the results in the quantitative part show that the percentage of influence of the locus of control feature is higher than other inertial features in the audit profession in the petrochemical industry, implying that the auditor’s encirclement on individual control in success and failure can avoid a set of external factors such as chance and lead fate in audit functions. In other words, an auditor with the characteristics of an internal locus of control tries to use his/her ability to express independent behavior in professional comments and judgments, regardless of external reasons
