Abstract:
A jetted check valve includes a body with an upper opening and a lower opening. The jetted check valve also includes a primary poppet slidably disposed in the body to allow the flow of fluid from the lower opening and out of the upper opening and prevent the flow of fluid from the upper opening through the lower opening. The jetted check valve further includes a secondary poppet slidably disposed at least partially within the primary poppet to allow the flow of fluid from the lower opening and out of the upper opening and prevent the flow of fluid from the upper opening through the lower opening. A method of removing debris from above a jetted check valve and permitting production fluids to flow up hole through the jetted check valve. The method includes creating a secondary flow path in the jetted check valve to remove debris that settled up hole of the jetted check valve when production of an oil and gas well has been halted. The method also includes creating a primary flow path in the jetted check valve to permit production fluids to flow up hole through the jetted check valve.
