Thermal Transient Testing Using Tds Technique

dc.contributor.authorNyame, Michael
dc.description.abstractIn the estimation of most reservoir parameters in well test, the reservoir is assumed to be isothermal which is practically not true due to the fact that there are heat sources due to friction in the wellbore, works done by the drill bit and in thermal recovery. Although, this temperature change is small, it can serve other beneficial purposes in the reservoir and wellbore. The research work used the temperature change to estimate permeability, skin factor and initial temperature of the reservoir. This work brought out equations to be used in the estimation these reservoir parameters and the applied to field data. These results obtained compared with the true reservoir parameters of field data were almost the same especially the permeability and initial reservoir temperature although the same could not be said about the skin factor since that of the estimated and true value were quite different. This research work brought out the idea that thermal transient testing can be used as a tool for estimating some reservoir parameters or as verification for estimated parameters using other well test methods. This research work also generated type curve for dimensionless temperature derivative versus shut-in time for different skin factors (damaged, neither damaged nor stimulation and stimulation) as well as type curve for dimensionless temperature derivatives versus shut-in time for different dimensionless radii with their respective behaviors.en_US
