Paper Number: SPE-203603-MS
... to be drilled in two sections: a pilot hole to the planned section total depth and then with a hole opener to open the pilot hole to the required hole size. Due to the abrasive formation type and difficulties encountered while drilling to the planned depth, decision was made to set the casing shallower than...

... the pilot hole and horizontal landing section to maximize recovery. A pilot hole was drilled to intersect the range 7147' to 7190' of possible OWC depths. The OWC was found to be very close to the most likely contact scenario. Subsequently, the producing section was landed at the optimum location...
