Transcripción del resumen del autor. The rapid post-fracture production decline rate often observed in both oil and gas wells is considered to be associated with loss of fracture conductivity, often attributed to invasion of formation fines into the proppant pack, loss of fracture width due to proppant flowback, and fines derived from proppant crushing. However, recent studies have indicated that solid material generated from geochemical process in the fracture face known as proppant diagenesis, may have considerable impact on proppant conductivity. Liquid resin systems (LRS), a specific type of hydrophobic material, have been used in the industry to prevent proppant flow back. The proppant is coated on the fly on location with a LRS. This technology has also proved to increase and sustain fracture conductivity over time. The production data presented in this paper comes from some low permeability gas fields located at the Burgos Basin in North Mexico which contains sand formations considered as a tight gas. The formation fractured is an intermediate/high temperature and high stress sandstone. The wells previously fractured in these fields had a historically rapid post-fracture production decline rate. The wells successfully treated with LRS material show a significant production increase compared to non-treated offset wells due to a substantial change of the conductivity of the fracture. Based on laboratory experiments on proppant diagenesis and field results, it has been concluded that the proppant diagenesis protection treatment provided by the LRS significantly contributed to the production increase of the wells treated.
