Rig spotlight: Trinidad Rig 56

Trinidad Drilling Rig 56

After 20 years in the business, we understand each drilling program has its unique challenges. That’s why we’ve designed and upgraded our rigs with features like back-up secondary systems, centralized control systems, moving systems and safety enhancements to drill deeper, longer and more technically challenging wells.

Rig 56, Trinidad’s first 2000 HP rig added to our fleet in 2011, is no exception. Designed with both natural gas and diesel-powered engines, we’re able to adapt the rig’s power source to fit our customer’s drilling programs.

Jake Hamdan, our in-house engineering expert and Trinidad’s Director of Engineering and Design, gives us a rundown on this adaptable rig.

Rig specs

  • Rig type: CanDrill 2000 (cable-raised mast)
  • Mast height: 72 metres (150 feet)
  • Drawworks: 2,000 horsepower
  • Hook load: 1,000,000 lbs (pounds)
  • Depth capacity: 8,000 metres (just over 26,000 feet)

The Rig 56 advantage

Powering Rig 56 from either natural gas or diesel engines gives us the advantage of “adapting the rig based on cost, power supply, operation and geographical location,” explained Hamdan.

If natural gas is not in abundance, Rig 56’s durable and powerful diesel engines are used.

“Diesel has a very high energy density – almost triple that of natural gas – meaning you get more power from a specific volume of diesel when compared to the same volume of natural gas,” said Hamdan.

Alternatively, if there’s natural gas in the area or it can be supplied through pipelines that already exist, Rig 56 can be powered off the natural gas engines instead.

The environmental and cost-saving benefits of powering rigs via natural gas is increasing in popularity in the oilfield. Hamdan noted that “burning natural gas emits about 25% less CO2 than diesel when combusted.”

Changing out the engines

Changing between Rig 56’s natural gas and diesel engines requires switching the fuel management, supply system and ignition system, explained Hamdan. We also have to switch out the generators to manage the lower power levels that are generated through natural gas.

Dual-fuel systems

Trinidad also uses dual-fuel systems to provide the ultimate optionality, enabling rigs to operate fully on diesel or run on a mix of both diesel and natural gas. Dual-fuel is a relatively cost effective way to add fueling options to our rigs and is an area of growing demand from our customers.

Looking for high-spec rigs with reliable crews? We want to hear about your drilling program. Who knows where it might take us? If Bruce Willis can drill nuclear warheads into asteroids in space, our possibilities just may be endless.
