Well 1: The section started at 1,207m, with inclination of 13° and built to 43° at 2,714m before dropping down to 28° for well TD at 3,288m.
Well 2: Section started at 1,169m, maintaining the 19° tangent section before dropping slightly into the reservoir to 16° at TD of 2,920m.
Well 3: Drilling started at 1,246m at 42° and built angle to 56°. At 2,601m, a formation fault zone was encountered with total drilling fluid losses. The PBL was activated but losses could not be cured using LCM. A cement plug was set, and a sidetrack initiated at 2,045m at 42°, building again to 56° at 2,684m then dropping down to 17° to TD the well at 3,700m.
Well 4: The longest of the four wells, the section started at 1,305m at 32° and built to 64°, before dropping back to TD the well at 18° at 4,100m.
Over the course of the four wells, the ROP was 30 to 35m/h (limited by rig constraints) and the mud weight was 1.1SG.
