Introduction

OverDrive System helps to expand capabilities of your top drive and use its 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

Removes personnel from the derrick and rig floor Removes equipment / scaffolding from rig floor Reduced risk exposure

Client Value - Safety


Flat Time Reduction / Hazard mitigation

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

Push down or reciprocate while rotating or circulating

Getting casing to bottom

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)

Russia operations


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

Why Sakhalin Energy chosen the system and what was achieved



One more 500 ton Modular system for Sakhalin Energy Lunskaya platform

Two Compact systems for application on continental

Test facility construction on Noyabrsk base
