Reverse circulation coring with extraction of existing pipes

If it was impossible to deepen or enlarge an existing well due to insufficient piping diameter, our technicians can extract the old column by coring. More precisely, we do a reverse circulation coring with large diameter till the bottom of the old well, than we drill deeper till the required depth, and finally we extract the old piping and we set down the new one in the same site.
