Set new operational benchmarks while achieving objectives
By using the OptiWell service, ADCO was able to complete the well in 36
days—2 days ahead of AFE—with no NPT and zero stuck pipe incidents.
Specifically, in the challenging 12 1/4-in section, early detection and action
taken upon signs of wellbore instability effectively prevented a stuck pipe
incident in that section.
Throughout the operation, cuttings recovery and hole cleaning were both
improved by changing drilling parameters. ADCO was able to reduce total
connection time 35% (23 to 15 min/stand) in the 8 1/2-in section and 31% (22.5
to 15.5 min/stand) in the 6-in section. The operator also increased on-bottom
ROP 18% (53 ft/h to 63 ft/h) in the 8 1/2-in section and 13% (63 ft/h to 71
ft/h) in the 6-in section.
These combined improvements in stuck pipe prevention, connection time,
and hole cleaning circulation yielded an estimated cost savings of USD 564,600
The pilot well was completed 2 days ahead of AFE, and further
time-saving opportunities around the cleanup cycle process were
