Hole Cleaning Sub

Next GenerationA Next-Generation (nxg) modular solution, it possesses technologically-advanced features to deliver the performance – and results – you want.

Easy to handle and rack back, and requiring no changes to drilling procedures, its unique design serves one core objective: maximum cutting beds removal.

Our Hole Cleaning Sub is a perfect example of OILSCO’s ideas in action – to benefit your drilling operations.

A durable tool that is located between sections of drill pipe to redistribute cuttings that settle out of the mud on the low side of the wellbore, it comes into its own in highly deviated sections – in excess of 40°– where the build-up of cuttings beds is often most acute.

CFD analysis has already shown that its innovative design is capable of delivering a clear increase in cuttings removal, over longer periods, compared to a drill string without any mechanical aid.

Key Features:

  • A patent pending unique impeller/spade design for maximum cutting agitation.
  • Industry standard Arnco 350XT hard banding application.
  • Placement programme for optimum hole cleaning performance.
  • Available with standard API connections or customer-specified premium connections.
