This paper validates the extent to which information on the Nigeria Extractive Industries Transparency Initiative (NEITI) data reporting systems is credible and valid, in reporting oil and gas revenues. To conduct a survey, 110 individuals were selected out of 150 employees. We would ask questions and discuss with significant individuals to get information. The questions were examined by professionals to ensure that they were alright. We administered a technique to determine whether the questions were trustworthy. We sussed numbers with statistics and sussed what people said in a special way. The outcomes will indicate procedures to maintain the safety of data, issues and the effectiveness of data checks in NEITI systems, to report oil and gas revenue utilising NEITI. They will also contain suggestions on how NEITI can make its revenue disclosure systems more stable and safer.
