Jack-up substructure drilling rig

The engineering company ENCE GmbH (ЭНЦЕ ГмбХ) offers gas production equipment as well as separate drilling tools and turn-key complete field construction projects for oil-production enterprises in the Republic of Turkmenistan (Turkmenia).

Technical Proposal

The jack-up substructure drilling rigs which can be supplied by the engineering company ENCE GmbH (ЭНЦЕ ГМБХ) to various gas production enterprises in the Republic of Turkmenistan (Turkmenia), are designed for drilling operations with hook load capacity up to 650 tons. The rig design includes jack-up and parallelogram substructure used for rotary drilling as well as for top drive drilling. This construction allows quick well-to-well displacement.
