Halliburton has successful field trial

Halliburton's Sperry Drilling Services announced the completion of two field trials of its third generation Geo-Pilot 5200 Series system.

Halliburton's Sperry Drilling Services announced the completion of two field trials of its third generation Geo-Pilot 5200 Series system.

The 5200 Series Geo-Pilot system completed its first field test for an operator in Canada, drilling the entire section (2,445 ft / 745 m) in 51 drilling hours, the company says. By choosing to use rotary steerable technology versus a conventional mud motor in the slimhole section of the well, the customer was able to eliminate the additional trip and rig time required to rearrange heavy-weight pipe, as is common in conventionally drilled horizontal wells.

The second field test was completed for an operator in Alaska where geosteering was required to maximize production from the horizontal reservoir interval. The 5200 Series system drilled the entire 7,145 ft horizontal in a single run, setting a world record for the longest run drilled with a rotary steerable in a 6 3/4 in. hole, Halliburton says. Using the Geo-Span downlink service, the Geo-Pilot 5200 Series system was efficiently steered without interruption for downlinking, giving the geologist complete control over wellbore trajectory and no loss of drilling efficiency, Halliburton says.

The slimhole Geo-Pilot rotary steerable system retains many of the main benefits of the second generations Geo-Pilot system concept, which points the bit by flexing an internal rotating driveshaft between bearings.

With the addition of the 5200 Series system to the FullDrift drilling suite, Sperry can offer a slimhole point-the-bit rotary steerable solution capable of significantly extending horizontal production sections and reaching small targets from existing structures. This can eliminate huge capital investments and extend the useful life of production facilities by restoring production levels, the company says.
