Abstract
This article investigated how external environmental forces amplify the susceptibility of Nigerian oil and gas companies to industrial espionage; how the firms can strategically respond to the threats of espionage to birth positive organizational outcomes such as corporate resilience, competitive advantage, and sustainable performance. Drawing upon the Resource-Based View as its theoretical anchor, the article synthesized extant literature in strategic management, information security and organizational intelligence to unravel how firms can transform espionage threats into opportunities for adaptive growth. Literature revealed that industrial espionage in the form of cyber intrusion, insider collusion, data theft, and deceptive intelligence, significantly heightens both strategic and operational risks by undermining innovation, eroding trust, and distorting competitive decision-making. However, the article demonstrates that organizations equipped with integrated strategic response mechanisms including intelligence governance frameworks, cybersecurity architectures, counter-espionage procedures, and ethical intelligence systems can not only neutralize these threats but convert them into catalysts for resilience and sustained performance. The article concluded that effective strategic responses to industrial espionage birth positive organizational outcomes such as corporate resilience, competitive advantage, and sustainable performance. The article contributes to the growing discourse on strategic intelligence in emerging economies by reframing industrial espionage as a transformative force rather than a purely destructive one. It provides both theoretical and practical insights for corporate leaders, policymakers, and security strategists seeking to institutionalize intelligence governance and fortify organizational resilience within Nigeria’s volatile oil and gas ecosystem.

Keywords: industrial espionage, resource-based view, strategic response mechanism, corporate resilience, competitive advantage, Nigeria’s oil and gas sector.

Abstract
This study investigated the relationship between transport management systems (TMS) and operational performance of oil and gas servicing firms in Rivers State. TMS was used as the predictor variable and was treated as unidimensional. Operational performance was used as the criterion variable and was proxied by operational flexibility, delivery reliability, and cost reduction. The study adopted cross-sectional survey research design. The population of the study comprised 33 registered oil and gas servicing firms. A census was taken. 3 copies of research instrument were sent to each of the 33 oil and gas servicing firms. The respondents include transportation manager, warehouse managers, and fleet supervisors. Thus, a total of 99 respondents took part in the study. Spearman Rank Order Correlation was used to test the hypotheses. The findings showed that TMS has a very strong positive and statistically significant relationship with operational performance. Based on these findings, we conclude that TMS predicts operational performance of oil and gas servicing firms in Rivers State, and recommends that oil and gas servicing companies in Rivers State should design and implement appropriate TMS if they seek to enhance their operational performance.

Keywords: Cost reduction, delivery reliability, operational flexibility, transport management systems.

Abstract
This study investigated the influence of supply chain robustness on performance of listed oil and gas companies in Nigeria. Supply chain robustness was used as a unidimensional variable while performance was measured using responsiveness, reliability and assets management efficiency. The study employed a cross-sectional survey strategy. The population of the study consisted 7 listed oil and gas companies, and a census was taken, while 35 respondents consisting supply chain manager, logistics manager, distribution manager, marketing manager and purchasing manager provided data. Data was collected using semi-structured questionnaire designed in the 5-point Likert-type scale. The questionnaire was distributed online using emails obtained from the companies. Responses 33 respondents were used for the study. Hypotheses were tested using simple regression with the aid of statistical package for social sciences version 23. From the analysis, it was found that supply chain robustness has varying degrees of significant influence on measures of supply chain performance of (responsiveness, reliability, and asset management efficiency). It was therefore concluded that supply chain robustness has a strong influence on performance of listed oil and gas companies in Nigeria. The study recommends that listed oil and gas companies should build capabilities that enable their supply chains and firms to prepare for disruptions so they can quickly ‘‘bounce back’’ from such disruptions.

Keywords: Assets management efficiency, organizational performance, reliability, responsiveness supply chain robustness.
