Expro Excellence
PowerChokes®
Expro delivers bespoke Managed Pressure Drilling solution
Objectives
  • Expro was approached by the customer to assist in drilling an additional well in West Texas
  • While drilling this formation the customer was experiencing large debris in the drilling returns.  This led to issues in packing off, which can result in Chokes becoming fully blocked
  • The formation being drilled was experiencing pressure related issues.  The customer was keen to implement Managed Pressure Drilling (MPD) techniques to help control the pressure
  • Other drilled wells in the same location had been encountering pressure issues, which had led to non-productive time (NPT).  The customer had not been able to reach their target depth
  • From a safety perspective, not being able to control pressures can lead to well control issues, which are critical, and this is something that all rigs aim to avoid
Expro Excellence


  • Our team was able to offer a 4" choke with low-pressure drop and the capability of flowing 2" debris which vastly reduce the likelihood of pack off
  • Expro's Automated Back Pressure (ABP) uses software that highlights pack off and can automatically engage the second choke
  • We provided a Pressure Relief Valve (PRV) system that reduced the pressure spikes if pack off happened
  • Our fully Managed Pressure Drilling (MPD) system operates with a crew of two or three people compared to other systems who require four to five people
Value to client
  • The customer had no pack off issues despite the size and quantity of debris which can be seen in figure 1
  • Expro's bespoke, cost effective Managed Pressure Drilling solution offered the customer a premium service, which resulted in being able to drill deeper. Currently, none of our competitors can offer such a high performing pressure control as can be seen in figure 2
  • Our chokes can identify both pack off and switch over, giving low frictional pressure at the surface
  • The customer had zero non-productive time (NPT) in this challenging well
  • Expro's MPD system requires fewer personnel to operate
