Deep exploration and gas wells with very tight formations to be hydraulically fractured in the Sultanate of Oman, have been preferably perforated with Abrasive Jet perforating systems in order to reduce the perforating skin and to be able to break down the formation compared to the regular deep penetration shaped charges which historically have been unsuccessful used. The complexity of the Abrasive Jet perforating operations requires Coil Tubing, Sand Management System (SMS), specialized perforator BHA, correlating devices, pumping and mixing equipment and a substantial quantity of fluids and sand per interval. Perforating guns with reactive liner technology, conveyed with electric line, have been considered for these types of wells. This technology delivers enhanced perforations facilitating fracturing operations by reducing the break down pressures. Initially well data from three exploration wells "A", "B" and "C" were extensively evaluated with very high chances to succeed. The job execution was planned parallel to the Abrasive Jet perforation in case the formation would have not broken down after the gun perforations. In well "A" two stages were executed successfully using the reactive liner shape charge technology while in the well "B" the first stage was neither broke down after reactive liner charges nor after Abrasive Jet perforations; the second stage in well "B" was successfully executed after the reactive shape charge gun perforations. This initial success of these two exploration wells was replicated in another gas field also with tight formations which historically has been perforated with Abrasive Jetting near well "C". As a result of this, the efficiency, the perforating accuracy and the cost savings are substantial improved; the HSE exposure is much less due to the fact that less resources are needed compared to the requirements for Abrasive Jet. This paper will go thru the design, planning, execution, results and the big step change in the fracturing operations in these types of wells in which Abrasive Jetting is not always the best preferred option.
