In this study, we compared quantities of gas flared by the Joint Venture Companies in Nigeria. The ultimate objectives of the study were to ascertain the patterns in quantities of gas flared by the individual companies, to determine if there was a reduction in gas flaring in Nigeria and to verify whether the reduction, if any, is uniform among the Joint Venture Companies. Data on quantities of gas flared and quantities of oil produced in cubic meters (m3) by the Joint Venture Companies were collected from 2015 Annual Statistical Bulletin of Nigerian National Petroleum Corporation (NNPC) through the The time plot of the data showed a general reduction in the quantities of gas flared by the companies over the period under review. However, the reduction was found not to be uniform across the Joint Venture Companies. This disparity in the patterns of quantities of gas flared was confirmed by virtue of Analysis of Covariate Residual (ANCOVRES
