Extended 카지노 보증 Drilling (ERD)

Extended 카지노 보증 Drilling (ERD) is a technology for drilling longer horizontal wells at a high inclination angle to 카지노 보증 underground oil/natural gas deposits further away from the drilling spot, instead of drillingwell

In exploration and development of oil and natural gas, we drill wells to 카지노 보증 subsurface deposits where oil/natural gas is likely trapped. However, in the event we are unable to drill wells from directly above town areas overlie them, we drill wells from surface locations at a short distance away, using the directional drilling technology. ERD is an advanced version of the directional drilling technology. More specifically, drilling at a high inclin longer distances.

In recent years, the ERD technology has been increasingly adopted in E&P projects. For instance, using the technology, we are able to locate and produce oil or natural gas from deposits below the seabed by diagonally constructing offshore platforms directly above these deposits and drilling vertical wells to 카지노 보증 oil/natural gas.

카지노 보증 Initiatives in Japan

The ERD technology has been applied in drilling of wells in Japan as well. In fact, JAPEX has accumulated experience and track record in drilling horizontally and vertically 카지노 보증 wells.

In 2014, JAPEX drilled a horizontal well with a total depth of 4,600m and a horizontal length of 500m at Yufutsu oil and 카지노 보증 field in Tomakomai City, Hokkaido.

Moreover, as part of the CCS (Carbon dioxide Capture and Storage) demonstration project offshore Tomakomai in Hokkaido, a government project Japan CCS Co., Ltd. (JCCS) has worked on and JAPEX completed in the JAPEX Group under₂injection wells for feasibility study. The ERD technology was used also for 카지노 보증 these injection wells

카지노 보증 of CO₂Injection Wells for CCS Feasibility Study in Tomakomai

In 2015, JAPEX completed the drilling of an extended 카지노 보증 well with a deviation or horizontal 카지노 보증 of 4,346m, a total drilling length of 5,800m, and a vertical depth of 2,753m. The well well deviation equivalent to 7 times the height of the Tokyo Skytree.
