With considerable drilling experience on land, Petrolog is equally experienced with offshore drilling. The following categories of drilling equipment are available for offshore drilling. Petrolog can provide offshore mobile drilling units (OMDU) through strategic partnership and collaboration with our joint venture partner companies.

Barges equipped with drilling rigs are suitable for drilling in shallow waters immediately offshore as well as in swamps in water depths up to 100 feet and can drill up to 15,000 feet deep wells.
Platform Rigs – Rigs operating from fixed platforms can drill in relatively deeper water.
Jack-up Rigs – These are capable of drilling in varying water depths and are equally capable of drilling in depths of 20,000 ft and in water depths of 100 ft.
Semi submersible rigs are suitable for drilling in water depths greater than 1000 ft. These semi submersibles are of two types. One type of submersible can be moored at the bottom of the sea floor (Water depth 1000 ft) and can drill up to 20,000 ft.   The second type is the one, which is dynamically positioned in the open seas in water depths of 6000 to 8000ft. These are capable of drilling up to 30,000 ft.
Drill ships are equipped with drilling rigs capable of drilling in any water depths. These are usually used to drill wells in water depths of more than 8000 ft., and can drill up to 30,000 ft.
