Remote sensing and GIS based results from the geometric characterization of braid bar deposits in the Niger Delta are presented in this work. In this study the geometry of 67- braid bar deposits from Landsat images of 1985 and 2015 were documented and compared to determine the relationship that exist between geometric dimensions and the amount of change that has occurred on them. The braid bars identified in this work are all associated with fluvial environment in the Niger Delta. Braid bars in 1985 are observed to be greater in length, width and area than those in 2015. R² values (0.6) indicate that a significant relationship exists between braid bar length and width. R² values also indicate a significant relationship exists between both length and area (0.7) and width and area (0.8) of the braid bars values within the study area. Thus, the utilization of width to predict the length and vice versa of braid bars is reasonable. Hence data from this study provides relevant information on size ranges that can be utilized for the efficient characterization, modelling and development of hydrocarbon reservoirs.
