Abstract
The role of the petroleum industry in Nigeria cannot be overemphasized. This work identified the determinants of delay in the delivery of materials to oilfields in Rivers State. A cross sectional survey with a sample size of 190 respondents was adopted for this study. Questionnaires were hand distributed to respondents. For the research instrument, a reliability coefficient of 0.82 was obtained using Cronbach alpha reliability test. The data obtained from the respondents were analyzed with product moment correlation coefficient. The outcome of the test show that poor planning with 0.72, government policies 0.86, weather conditions 0.74 and logistics 0.782 were key determinants of delay in the delivery of materials to Oilfields in Rivers State, Nigeria. If these sources of delay are addressed, profitability in the industry could increase through reduction in unit cost of production. Poor planning Issue 3/2023 156 and logistics can be addressed through efficient staff recruitment and training.
