Technology for Today’s Drillers, TESCO’s Top Drive System

Over a decade ago, Tesco Corporation pioneered a technology that made modern

drilling procedures available to most rigs.

With the ability to bring time and cost effi ciencies to any drilling application,

TESCO’s line of hydraulic and electric Top Drives has proven successful on rigs

worldwide. In every location land-based or off shore, from the frigid Arctic to

desert heat, urban locations to remote jungle, anywhere there is a well to be

drilled, a TESCO Top Drive can improve operations.

P A G E 3

With the widest selection and greatest number of exclusive features, TESCO

Top Drives represent the world standard in sales and rentals.

Selection Like No Other

From the largest off shore or conventional

derrick styles down to small truck-mounted units,

there’s a TESCO Top Drive to meet your needs.

Hydraulic or electric units are available from 150

ton to 750 ton, 400hp to 1350hp.

Ease Of Installation

Packed securely in three standard shipping

containers, TESCO Top Drives can be transported easily and aff ordably by

truck, rail or sea. They can also be broken down into smaller modules for

easy delivery by helicopter or as air cargo. Once on location, TESCO Top

Drives can be installed on most drilling rigs with little or no modifi cation to

the rig.

Ease Of Operation

The TESCO Top Drive control panel is designed to be easily understood

and operated by the driller. On-site TESCO technicians are available to

help achieve maximum Top Drive drilling performance. Specially trained

technicians know drilling processes as well as TESCO’s equipment, and

provide both maintenance and training for the drilling crew. In addition,

advanced factory training is also available.

Versatility At Its Best

In extremely cold climates, a one-piece skid building is available to

enable maintenance and operation of the power unit in temperatures

below minus 40°C. Units have been operated to 56°C with optional high

temperature packages. For off shore platforms or other locations where

space is at a premium, the power unit can be split and stacked with a

TESCO stacking kit. If ambient noise is a consideration, various soundproof

buildings are available to signifi cantly decrease the sound of diesel powered

hydraulic systems.

Our top drive systems are

easily transported via truck,

ship, helicopter or airplane.

TESCO top drive systems’ innovative

design and worldwide availability of parts

and support services have resulted in

a remarkable record of 99.3% uptime.

Double and triple stands of pipe can

be made up in advance and drilled in,

reducing the number of necessary

connections by 50 percent or more.

P E R C E N T • U P T I M E

C O N N E C T I O N SL E S S

On-site supervision

and user training ensures

maximum drilling performance.

Understanding the TESCO Difference

P A G E 4

In the event of a kick, the well can be secured with the double

ball valve.

• Provides a second alternative to traditional “stabbing valve” well control

procedures.

• Driller can shut-in the well without drill fl oor crew – even while

tripping.

We at TESCO can make your rig more effi cient, and a safer

environment to work.

• Automation of the rigs.

• Safety improvements for rig fl oor crew.

• Elimination of manual tongs to make up connections.

• Quicker connections.

• Ability to close the safety valve remotely at any height in the derrick.

• Possibility to add Stabbing arm.

• With the addition of Power slips, back up tongs are virtually eliminated.

Whether your specifi c drilling operation calls for directional, horizontal,

underbalanced, air or gas drilling, reaming, running casing, well control,

or fi shing, the TESCO Top Drive can contribute in ways that will save time

and money. Here are some practical examples of what a TESCO Top Drive is

capable of and what that means to you.

A TESCO Top Drive can connect to the drill string at any height in

the derrick and provide simultaneous reciprocation, rotation and

circulation of drilling fl uids.

• The ability to ream and backream with full stands.

• Eliminates the need to pick up the kelly to begin circulation and rotation,

thereby decreasing the risk of becoming stuck.

• No need to break stands into singles for reaming.

• No requirement to pump out singles with the resulting hole problems.

The Top Drive can rotate the drill string both clockwise and

counter clockwise with highly controlled torque.

• Ability to “rock” the drill string in order to break the static friction while

“slide drilling”. This allows the drilling of extended horizontal sections in

shallow wells.

• Capable of making “on bottom” connections with the drill string,

eliminating the need to re-orient the drill string in “slide drilling”.

• Facilitates free-point and back-off operations during fi shing.

Double or triple stands of pipe can be made up in advance and

drilled in with the TESCO Top Drive, thereby reducing the number

of necessary connections by 50% or more.

• In air or gas drilling, decreases the number of connections and thus the

“blow down” time.

• Decreases the amount of time that the hole is not underbalanced in UBD

operations.

• Allows 20 or 30 meter core barrels to be drilled without a connection,

decreasing the chances of a “jam-off ”.

The TESCO Top Drive allows for continuous fi ll up and/or

circulation while running casing.

• Saves time fi lling casing.

• Allows circulation, rotation, and reciprocation of casing.

• Decreases circulating time and stuck casing risk.

“Link Tilt” and “Extend” robotics assist in casing handling.

• Increases safety and speed when running casing.

• Reduces need for specialized casing running equipment.

Using the Top Drive Practically

Electric Top Drives

Available from 400hp to 1350hp, TESCO permanent magnet or

AC electric Top Drives are the ideal choice for modern rigs (land or

off shore) with suffi cient electric power.

Hydraulic Top Drives

Available from 475hp to 1205hp with self-contained AC over

hyraulic or diesel prime movers, these units are the traditional choice

for portable installation or for re-powering older mechanical rigs.

TESCO rental Top Drives are available from our International Service

Divisions. These units can be economically shipped and quickly

installed in almost any rig worldwide. An experienced TESCO Top Drive

technician is supplied with every rental unit to ensure the customer

receives maximum benefi t from the Top Drive. Both hydraulic and

electric Top Drives are available for sale in new rig construction,

rig upgrades and permanent installations. A selection of models,

combined with accessories, on-site Installation supervision and factory

training ensure that the customer receives real value for their TESCO

Top Drive investment.
