“…The American I scoring Scientific Society developed scientific requirements that include core quality, desired core length, number of deflections per core at a specified depth. [20] Although applications are available on the mainframe, Direct links to engineering applications Not provided. Both systems have met the reporting requirements, but Does not support planning or rig site operations.…”

Drilling engineers in general Extraction and production of oil and gas Used by multinational corporations. Existing Safety measures for evaluation and maintenance of wells Design elements to ensure implementation and they are also responsible for estimating the cost of machinery and construction. The main educational qualification for them is Bachelor's degree in Geology or Mechanical but sometimes equivalent credits are given in Petroleum Engineering. Drilling engineers must have excellent knowledge of physics, geology, chemistry and mathematics, as well as strong IT skills.

“…In fact, the successful deployment of the DISC/replicate coring drill partially solved the problem of replicate core drilling. This drill is able to take 108 mm diameter replicate ice cores from the larger-diameter parent borehole, and during the 2012/13 WAIS Divide field Antarctic season the system produced five azimuth and depth-controlled deviations at four target depth levels (Shturmakov and others, 2014). Unfortunately, the system is extremely complicated, expensive and can work only from the DISC parent hole (170 mm).…”

More than 170 years ago, Louis Agassiz, one of the creators of glacial theory, made his first attempt to drill into the bed of Unteraargletscher, Swiss Alps. Since that time, various systems for thermal and mechanical drilling have been designed especially for boring into ice, and some conventional drill rigs been adopted for ice coring. Although contemporary ice-drilling knowledge and techniques are now familiar, there remain many problems to be solved by advanced modern technology. Specific challenges related to improving old drilling methods and developing new emerging technologies include: (1) identification of depth limitation of ‘dry’ drilling; (2) improvement of casing; (3) searching for the new environmentally friendly low-temperature drilling fluids; (4) reliable elimination of sticking drills; (5) improvement of core quality in the brittle zone; (6) additional core sampling from borehole walls after the core has been drilled; (7) obtaining oriented core; (8) designing automation drilling systems; (9) developing rapid-access drills. Possible ways of solving these problems are presented below.

“…As the international deep ice core drilling technologies, Augustin and others (2007b) reported on warm ice drilling in the deeper part of the ice sheet, Johnsen and others (2007) on the Hans Tausen drill developed at the University of Copenhagen and Shturmakov and others (2014) on the DISC drill developed in the USA, respectively. Talalay (2014, 2016, 2020) summarized drill heads of the deep ice electromechanical drills, mechanical ice drilling technology and thermal ice drilling technology.…”

The Japanese second deep ice coring project was carried out at Dome Fuji, Antarctica. Following the drilling of the pilot hole in 2001, deep ice core drilling led by the Japanese Antarctic Research Expedition (JARE) was conducted over four austral summer seasons, beginning with the 2003/04 season and reached a depth of 3035.22 m near the bedrock in January 2007. The new drill was designed and developed with the goals of (1) solving the problems encountered during the first JARE deep coring drill and (2) achieving more efficient drilling. In particular, the maximum core length that can be drilled at one time was increased from 2.30 m to 3.84 m and the chip storage efficiency was enhanced by a special pipe with many small holes. This paper gives an outline of the improved drilling system, the progress of drilling and various drilling data.
