Customer Testimonials
“Clearly the Turborunner provided benefit and we are excited about running it again.”
Vic Estes Drilling Engineering Manager, Anadarko
“One technology that we are currently testing and seems to be very promising is the Turbocaser Express.”
Zuhair Al-Hussain VP, Saudi Aramco Drilling & Workover Group
Statoil’s Senior Engineer, Drilling Operations, Michael Mountford, said: “The Turbocaser Express
functioned well and we believe it was a contributing factor to getting the liner down successfully. We are
likely to use it again in the future”.
Senior Drilling Engineer for CNR International – Stephen Cameron, commented: “The Turborunner is a cost
effective solution which greatly enhances the successful running of the liner string in potentially unstable
formations, without compromising the well”.
Senior Drilling Engineer for PetroCanada UK - Steve Salter, commented: “We felt the tool gave us an
operational advantage with little or no operational risk and were happy with the performance it provided.”
Malcolm Banks, wells team leader at BP, said, “We are supporting this development as Turbocaser will
deliver significant cost reduction to our intermediate casing operations in difficult formations. Currently,
rotation of large intermediate casings is expensive and Turbocaser gives us a more reliable and costeffective reaming solution. The fact that Turbocaser is drillable allows additional operational efficiencies
and reduces risk.”
Customer Testimonials
Senior Drilling Engineer for Occidental, Carlos Mercado, commented about a successful Shalerunner run in
Texas achieving successful placement of 5 ½” casing in a troublesome Wolfbone development well: “We felt
the tool gave us an operational advantage with little or no operational risk and were happy with the
performance it provided.”
Rod McNeill, Newfield Chameleon State 2H, said: “Without Shalerunner we would have never considered
running production casing with the Baker 24 stage Frac Point completion without making a dedicated
reamer trip”.
