This course provides in-depth background and state-of-the-art tools necessary to  maximize the performance of Hz wells. Practical examples will illustrate how  candidate horizontal wells are selected and designed using multi-disciplined team  efforts to ensure both technical and economic benefits are maximized. Methods  used to predict well performance; such as, expected producing rate, drainage  area, and fluid coning will be explained through class problems. Optimization of  Multi-stage Fracing of Horizontal Wells (MFHW), including the number frac stages,  spacing between the frac stages, size of the fracs, and how to take advantage of  the “sweet spots”, will be illustrated using advanced software. The art of well test  interpretations will be discussed including the benefits of Mini frac (DFIT) to  improve the frac design. The challenge of reserves estimate for  tight/unconventional reservoirs using advanced decline curve analysis and  probabilistic techniques will be reviewed. Excellent course notes will be provided.
