Transient, sandface temperature solutions for horizontal wells and fractured wells producing dry gas

This work first develops transient sandface temperature solutions assuming linear flow into a planar sink as a representation of a horizontal well (or a fractured well). Simplified forms of these equations are developed, making the application of TTA easier. Finally, the effects of heat transfer between the formation and the surroundings, and the effects of flow convergence into horizontal wells are considered. The combination of these for TTA in a horizontal gas well when combined with the existing TTA solutions for a liquid producing horizontal well lays the basis for a comprehensive transient analysis framework for multi-phase production, horizontal wells.
