Northern Canadian Well HPHT Company Information Your organisation is a large oil and gas company who explore for both oil and gas and have extensive infrastructure for the transportation of both in the area being explored. Location The well you have been asked to plan is located 120 km northwest of Fort Nelson British Columbia, 59.651706, -123.008860. Your expected lease site is about .750km from a provincial highway. Well details: The well that is planned in a high pressure, high temperature gas well in the Horn River Basin. This well will be used for production. The maximum planned dogleg severity is 6 degrees / 30m. The average ROP for the well is expected to be about 15 m/hr. Complications regarding high torque and drag are expected. Extensive LWD data is required.
