Abstract
Methods of preventing the production of sand with fluids produced from a subterranean formation penetrated by a well bore are provided. The methods basically comprise the steps of preparing a resin composition which delayedly forms a hardened open cell foam capable of allowing the passage of well fluids therethrough while screening and preventing the passage of formation sand and then placing the resin composition adjacent to the formation by way of the well bore.
