OBARETIN WELL

The research looked at the sedimentary process and the exact period of environmental deposition in the imo formation. From the thirty-two (32) ditch cutting samples that were collected and processed, twelve (12) samples were forwarded to the Activation Laboratory for geochemical analysis with the aid of the Ultratrace 7 package. The sample was taken from a depth interval of 1060 feet (1,060 meters) at the Obaretin Well in Nigeria's Benin flanks, where it undergone a complete geochemical study. Twelve samples were taken, and they underwent an effervescence test using diluted hydrochloric acid (Hcl). On the sample, carbonate was detectable. There was some strong (3), moderate (2), and weak (1) effervescence notices. Applying the aforementioned elemental proxies, such as trace, major, rare element the following was determined: grain size, paleosalinity, paleoproductivity, and paleooxygenation. For the grain size, silicon and aluminum, (Si/Al), when silicon increase the aluminium decrease the grain size from sample was coaser and larger in size. While strontium and barium (Sr/Ba) were the proxies used for paleosalinity, the trend line shows that higher salinities created marine environments, while lower salinities create river channels. A decline in paleoproductivity results in a low input of terrigenous material, whereas an increase in paleoproductivity results in deposits of rich terrigenous material. Barium and aluminum (Ba/Al) were utilized as proxies in the paleoproductivity study. Oxic, suboxic, and anoxic environments are the core topics of paleo oxygenation. Numerous elemental proxies, such as Molybdenum and Vanadium (Mo/V), were employed. Environment quality is determined by paleooxygenation. This study has helped in understanding fully about the sedimentary processes and depositional environment.
