This study investigated accident rates among oil and gas operators in Rivers State, Nigeria. Using a quantitative method with a questionnaire designed of different categories of questions, weighted average was employed together with other statistical tools like,Duncan statistics, bar and pie charts, etc., using SPSS and Excel. The sample size and questionnaire distributed were 370, and 342 were returned, representing 93%. Company A, B, and C staff represented 24.6%, 28.9%, and 24% of the respondents, respectively. We selected 7.9% of respondents from the Directorate of Company E to evaluate the insight and experience of regulatory agencies. Table 2.0 (a) shows that 66.4% of respondents are drawn from the upstream sector, while 33.6% are from the downstream sector. The results showed that the rate of accident occurrence in the last five years in the selected companies was 14.9% (frequency of 51) (see Table 2.0 (b). The outcome of the ANOVA showed that the variation in perception for different categories of workers is significant at p< 0.05, F - 4.035, sig 0.014. Since the significance level is below 0.05 (p-value), it indicates that there is a statistically significant variation in the knowledge of the different categories of workers about safety regulations and compliance.
