throughout the life cycle of your equipment.

Available for both new and existing Top Drives, Tesco presents

Automated Rig Controls (ARC) - a technologically advanced,

software-based platform designed to enhance and optimize

the drilling process. ARC takes input from Drilling Engineers,

Drillers, Directional Drillers and live rig data to accurately model

drill string characteristics and adjusts top drive parameters

in real time. Data flow between ARC components and the rig

enables an optimization of well profile, rate of penetration (ROP)

and bit life. Additional functionality available with the ARCFit

assists rig personnel in managing the maintenance and service

of drilling equipment.

New Tesco Electric Top Drives can now be delivered “ARC-

Ready” upon request, equipped from the factory with the

features necessary to run Tesco’s drilling optimization suite

of products. Components include a Top Drive mounted

Remote I/O, a VFD PLC panel, an ARC-Ready Driller’s Panel

and an updated Service Loop. For retrofit Electric Top Drives,

a hardware kit installation and integration will be required

to ensure full ARC functionality. No matter your Top Drive,

options for user interface includes a choice of Tesco-supplied

touchscreens or the ability to supply your own. In order to

remain connected to back office drilling support staff and to

have data available globally, customers may choose a Tesco-

supplied satellite or connect the ARC system into their own

internet connection.

Once the hardware is installed, customers have access to the

ARC suite of drilling optimization products with a subscription.

aRcTork™Tesco’s ARCTork maximizes your ROP, plus it lengthens the life of your bit and BHA tools.

Drill string anomalies such as stick-slip present challenges in

the drilling process that can lead to equipment damage and

reduced ROP.

When stick-slip occurs in drilling, the bit slows down or even

stalls on bottom intermittently as the bit “sticks and slips”,

resulting in significant torsional vibration. The result of this

condition causes severe stress on downhole tools, damage to

drill pipe connections, decreased ROP, decreased bit life and

severe wear on top side drilling equipment.

Tesco’s ARCTork system for reducing stick-slip improves

rotary drilling efficiency by mitigating the vibrational effects

that create stick-slip. The ARC system uses drill string, well

plan and live data parameters to determine if stick-slip is

occurring and auto tunes the VFD parameters to keep your

equipment operating optimally.

Features & Benefits:n Dramatically dampens vibration by mitigating stick-slip

while drilling and reamingn Reduces damage to equipment, therefore extending the

life of the drill bit and other BHA equipmentn ROP is increased and time is saved for the entire drilling

operation by mitigating the effects of stick-slip

Tesco’s ARCSlide maximizes your ROP during directional drilling operations.

The ability to drill long reach horizontal wells has been

partially achieved by reducing the friction caused by the drill

pipe lying flat in the well bore and maintaining weight on bit

by oscillating or rocking the drill pipe. In traditional manual

methods to oscillate while drilling, the driller must mark the

pipe and count the number of pipe rotations that have gone

into the drill string to know when to change the direction

of the pipe’s rotation. Tesco’s ARCSlide oscillation system

provides an automated solution. The ARCSlide software

utilizes intelligent control algorithms to automate drill string

rotation resulting in a reduction of well bore/drill pipe friction,

allowing for an increase in weight on bit resulting in higher

ROP.

ARCSlide, when used with a mud motor, eliminates the need

for expensive rotary steerable technologies.

Horizontal and directional wells are only successful if the drill

bit stays on target throughout the entire well bore. Traditional

methods of adjusting the tool face incrementally until the

desired outcome is obtained can be time consuming and

challenging. Tesco’s solution to automate this process

is the ARCGuide tool face control system that can work

independently or with the ARCSlide oscillation system. Once

the well plan has been loaded into the ARC system, the

ARCGuide calculates the required Top Drive movement to

correctly affect downhole tool position in order to optimize

the well bore construction. Manual tool face control can

also be used when the driller wants to control Top Drive

operations.

Tesco’s ARCGuide can also be used in combination with

Tesco’s ARCSlide system in order to automatically correct the

tool face while in oscillation mode. These systems working

together reduce the need for driller interaction and increase

drilling efficiency by minimizing course corrections.

ARC customers also gain access to an exclusive web portal

called Tescomation. This platform provides the viewer

full access to all of the data collected through any of their

equipment running Tesco software. Tescomation allows

customers insight into the status and location of equipment.

Beyond that, Tescomation also contains helpful features like

the automatic alert system which sends a notification when

equipment has exceeded a safe level of operation.

Tesco’s ARCFit helps track equipment maintenance and predicts future events.

TescomaTion™

Complementing the ARC software, the ARCFit is Tesco’s

solution for ensuring rig operations keep running smoothly.

ARCFit uses a sophisticated system of sensors,

communication infrastructure and real-time monitoring

support to keep equipment running. The system monitors

pressures, fluid flows and temperatures – constantly

monitoring critical components. In addition, shock and

vibration sensors are included in ARCFit which allows for the

prediction of critical system failures by analyzing real-time and

historical data. Depending on the condition or the parameter,

real-time alerts can report when parameters have exceeded

set limits.

ARCFit software provides a resource for both on and off-

site staff to view current status of their equipment in real-

time, view equipment location and perform preventative

maintenance by recording and reporting maintenance and

service events. Having historical data available also aids in any

troubleshooting that may occur, thereby reducing NPT.
