Introduction • OverDrive System helps to expand capabilities of your top drive and use it’s rotational power for tubular make ups

• OverDrive System completely replaces conventional set of casing running equipment (elevator, slips, power tong, fill up & circulation tool, weight compensator)

• Incorporated swivel allows string rotation and push down casing while running, circulating, reciprocating or cementing

• Integrated TorkSub measuring shaft gives more precise torque readings

Introduction Flat Time Reduction / Hazard mitigation

Getting casing to bottom

Push down or reciprocate while rotating or circulating • Increased Drilling Performance (casing running & reaming) • Reduces potential for differential sticking • Potentially eliminate dedicated wiper/reamer trips

• Increased Drilling Performance (Drilling w/ Casing - DwC™) • Eliminates drill pipe and bottom hole assembly • Reduced well bore exposure/damage • Improved borehole quality • Improved cement jobs

Experience globally and in Russia Russia operations

•

Currently OverDrive systems successfully supports only one offshore project on Piltun platform with Sakhalin Energy Company

•

9 wells completed, 24 casing jobs totally without serious incidents or NPT

•

Casing sizes from 18-5/8” to 5” , sections lenghts up to 4000 meters

•

20 persons qualified to operate the system (10 Sakhalin personnel, 10 continental Russia for future projects)

12

Experience globally and in Russia Why Sakhalin Energy chosen the system and what was achieved

•

Safety (reduced crew size, no personnel on rig floor, less manual operations) in severe northern conditions

•

Abilityy to get casing to bottom mitigating formation hazards

•

It turned out that OverDrive operations are faster than conventional comparing with Sakhalin Energy twin Lunskaya platform in spite of the fact that speed was never high importance criteria for choosing this system

•

Three occasions when OverDrive System was utilized to rotate the string in order to pass tight spots. Absence of system would lead to casing pulling out, serious NPT figures and unplanned costs

13

Experience globally and in Russia Plans for current year

•

One more 500 ton Modular system for Sakhalin Energy Lunskaya platform

•

Two Compact systems for application on continental

•

Test facility construction on Noyabrsk base
