| Sand and sand-based materials became the most popular type of proppant due to availability and low cost. However, a study of production rates published by the Society of Petroleum Engineers has shown that the additional strength and uniform size and shape of ceramic proppant provide higher performance than other types of proppant (SPE 77675). Wells that have been fractured with ceramic proppant consistently exhibit improved production of oil and gas in a variety of reservoir condition.
?There are different types of proppants.Proppants options effects the output. The main contents of proppant selection includes the type, size and concentration. Proppant selection and the pressure of the rock strata, closely linked to environmental conditions and production requirements.
?It is basically controlled by the closure pressure, when the closure pressure is low, the choice of quartz sand as a support agent; when the closure pressure higher, generally used in high-intensity strength ceramic or ceramic. Fracturing proppant selection is according to the requirements of fracturing conductivities and economy. Usually more than 3000m deep in our selection of ceramic, ceramic in deep fracturing chase. |
