The distribution of Formation Temperature of the Fika Shale Formation within part of Borno basin from five wireline logs was investigated. The area under studied covered about 20 by 40 kilometre square of the total land mass of the basin. The Fika shale sequence were identified at 865m to 1795m in Kinasar well, 640m to 1990m in Krumta, 980m to 1620m in Masu, 700m to 2710m in Tuma, 710m to 2220m in Wadi. The plot of the entire Formation Temperature of the study area reveals remarkable steep variations in temperature with increased range from 680C to 1280C starting from the southern eastern region to the north western region. This is possibly due to substantial temperature enhancing effects of the underlying basement complex. Interestingly, it was also observed that the minimal temperature variation occurred approximately 20C/ meter across the field and this also lays credence to the fact that the notable subsurface geothermal variation may be recent events initiated by the near- surface magmatic intrusive events which may have had adverse effects on the overlying sedimentary cover. Furthermore, it was deduced that the probability of hydrocarbon accumulation is better in the south eastern region than the north western region although the steep temperature variation of 20C/ meter within some part of the study area may perhaps reduce this possibility.
