From spud to TD, the Joanne 30/7a-Pl 1 well was drilled to a measured depth of 23,035' in 23.65 days. This extraordinary performance was achieved despite a 1600' sidetrack in an upper hole section. Adding time for skidding over the well slot, logging the reservoir interval, running and cementing the production liner and suspending the well brought the total time on the well to 31.65 days. The horizontal displacement for this extended reach well is 18,560', including a 4287' horizontal section in the thin Palaeocene Andrew sand reservoir. PI 1 was the eleventh well drilled on the Judy template using the Santa Fe Galaxy jack up drilling rig in Phillips J-Block development The drilling program featured a diligent and continuous search for methods to improve performance. This resulted in the implementation of several innovations during the course of the project A continuous improvement trend was clear throughout the template drilling project culminating in the PI 1 well. Several world records were set while drilling this well, including the 24 hour footage and total footage in a single run. This paper will present the techniques used in the P11 well to show how the impressive result was achieved. |
