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

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

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

OverDrive™ System Real Results

Petrobras Marianas:ran 18” and 9 5/8” on first Deepwater well in Colombia. Saved (8) hours of rig time compared to conventional run times

Bp Caspian:remote operated equipment eliminated manual handling of conventional casing running equipment. Running on (5) rigs. Improved run rates by 15%.

Exxon Heritage:floated in 18,000’, 28,000 9 5/8” casing strings. Rotated entire string.

Shell Brent:ran 18,208’ casing in 80°

deviation. Previously took (3) weeks to remove drill string. No hole cleaning.

Shell Brent:ran 18,208’ casing in 80°

deviation. Previously took (3) weeks to remove drill string. No hole cleaning.

BP Liberty:scheduled to run 6,200’ 20”, 19,000’ 16” and 36,000’ 11 7/8” casing strings

Nexen Scott:ran 17,286’ 9 5/8” casing in 75° deviation. Severe losses, sticky hole during BHA trip out. 40 hours working casing string.

Eni Black Tip: DwC entire surface and intermediate casing strings

Eni Black Tip: DwC entire surface and intermediate casing strings Ecopetrol:DwC 13 3/8”

Ecopetrol:DwC 13 3/8”

Eni, RWE:After conventional attempts to run casing unsuccessful, OverDrive used to get casing to TD

Bp:Rotated 13,000’ 13 3/8” casing string to TD

SEIC Sakhalin:ERD wells, extreme arctic environment.

Experience globally and in Russia

•

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)

(14)

13

•

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

(15)

14

•

One more 500 ton Modular system for Sakhalin Energy Lunskaya platform

•

Two Compact systems for application on continental

•

Test facility construction on Noyabrsk base
