Abstract:
An apparatus for cutting sections of a wellbore tubular includes a housing shaped to enable movement along an interior of the tubular. The housing has an upper end arranged to connect to a conveyance and a lower end comprising a guide. Cutting materials are disposed in the housing and arranged to cut the wellbore tubular in two, longitudinally spaced apart circumferential cuts and at least one longitudinal cut extending between the circumferential cuts. The cutting materials are arranged to create the circumferential cuts simultaneously or with a time delay chosen to optimize energy created when cutting. A method for cutting wellbore tubulars includes positioning the apparatus at a selected position in the wellbore and actuating the cutting materials.
