2. Operation Challenges
Geological challenges:
1. Few drilling data in this block; 2. Big change in lithology; 3. Exist High Pressure salt formation above 1800m; 4. Leakage zone in horizontal section, the safety window of mud
• Horizontal section: through the resistivity and GAMMA real-time data tracking reservoir, through the survey data to adjust the track to ensure oil drilling rate of 100%, increase drilling efficiency and well production.

Experience
• In China, GWDC has drilled 1,039 Horizontal Wells, more than 5,000 Directional Wells which includes more than 3,000 cluster wells. • Globally, in past three years, GWDC has finished 146 horizontal wells in Kazakhstan, Sudan, Thailand, Cuba, Colombia, Uzbekistan and other regions.
4. Geology-Oriented Technology
Build-up section by MWD+GAMMA and horizontal section with LWD (include MWD, GAMMA and Resistivity)
• Build-up section: to adjust the trajectory through MWD and motor, to distinguish the formation through GAMMA data and logging data; combined with MWD survey data and GAMMA data, client can calibrate the TVD.
