As part of HWYH Gas Plant development, hydraulic fracturing campaign commenced in 1998 to stimulate the sandstone and carbonate formations in the Ghawar gas fields in Saudi Arabia. To date, over 200 wells have been matrix acidized, acid fractured, and proppant fractured. Whereas post-treatment performance provides a good indication of treatment success, pressure transient analysis (PTA) remains the best approach to determine the effective fracture parameters such as fracture half-length and fracture conductivity. Knowledge of these two parameters is a key element to the optimization of hydraulic fracturing process.
