A'- method for accessing a subterranean zone ( 12 ) includes ' forming ' a " ' subterranean cavity (38) coupled to a land surface (16 ) and forming a plurality of substantially horizontal bores (22 ) extending at least partially into the subterranean zone ( 12 ) and intersecting the cavity ( 38 ) . Liners (40 , 140) may traverse the cavity . Also the cavity may be gravel packed (38) .
