Method of particulate consolidation
Patent
·
OSTI ID:6572508
This patent describes a method of consolidating incompetent particulate in a subterranean formation surrounding a perforated cased well penetrating the subterranean formation. It comprises: introducing a consolidating fluid including an acid curable resin into the cased well which is capable of coating particulate in the formation and positioning the fluid in the vicinity of the perforations; introducing a gas generating charge into the cased well and positioning the charge in the vicinity of the perforations; igniting the gas generating charge; coating at least a portion of the incompetent particulate in the formation with the consolidating fluid; catalyzing the acid curable resin in the consolidating fluid introduced into the formation by the combustion product gases by contact with gaseous acidic products produced during combustion of the gas generating charge; injecting a displacement fluid into the cased well; and introducing an aqueous acidic compound into the formation.
