Turbine Frac-Pumper Increases Power

The Jereh Apollo 4500 turbine frac-pumper was launched in March. The Apollo turbine frac-pumper is powered by a 5,600 hp engine weighing 700 kg with a power density 20 times that of a diesel engine. The pump weighs 37 tons and is 10 m in length, optimizing its flexibility and transportation.

Eight sets of Apollo turbine frac-pumpers can complete the work of 18 sets of 2,000 hydraulic horsepower (hhp) frac-pumpers with up to 36,000 hhp, for large-scale fracturing operations. In addition, there is 55 percent savings on well site covering and onsite high/low pressure manifold connection.

The core component of the frac-pumper is the Jereh pump JR5000 at 5,000 hp, the power increase being a key factor in developing higher output power for fracturing equipment (usually a 2,250-hp plunger pump is most commonly used in the market). This unit realizes the perfect match of a 5,600-hp engine at 16,000 revolutions per minute.

The Jereh 5,000 hp plunger pump also solves three core tasks of high-speed and high-torque gear box design, continuously variable transmission control technology and noise reduction technology.

Further advantages of the Apollo turbine frac-pumper include cost-efficiency and environmental protection. Fueled by wellhead gas at the price of $0.17 per cubic metre, the cost of the turbine engine is reduced by 82 percent compared with the cost of a diesel engine, the manufacturer states.

If a 40,000-hp Apollo frac-spread is operated for 1,000 hours in a year, savings would be about $6.5 million per year, a significant amount for global unconventional oil and gas exploitation.

The turbine engine is also designed with a 30-year service-life and maintenance cycle. There is no need to dismantle it when cleaning and it can be washed directly with water. Moreover, life of innovated fluid end is increased more than five times than those in the market, according to Jereh.

The Apollo turbine frac-pumper easily meets EPA Tier 4 emission requirements, while noise reduction technology keeps it under 95 dB (A).

New CT drilling technology delivers downhole results

Lubricant is the time-proven solution to more than a dozen major drilling challenges.

For oil and gas operators worldwide, friction has been the major nemesis of downhole drilling since the industry’s inception. Yet, despite the industry’s ongoing innovative technology as a whole, friction is the one problem that experienced no real breakthrough solution until scientists in a California laboratory developed a unique lubricant. That technology, after proving it could improve downhole drilling, became the building block for spin-off technologies including one for the increasingly popular coiled tubing (CT) drilling.

New Motor Lasts Longer and Enables Deeper Drilling

New Motor Lasts Longer and Enables Deeper Drilling

BEI Kimco Magnetics has introduced a new, rugged brushless DC (BLDC) motor that was developed specifically to withstand the harshest conditions found in the Oil Exploration Industry. The robust design also makes it suitable for other applications found in severe environments where failure is not an option. As the extraction of oil reaches greater depths, drilling equipment must continue to operate reliably in increasing temperatures and pressures, while also enduring extreme shock and vibration. In an industry where one hour of downtime can cost upwards of $100,000, having durable products that have been tested and proven to last is crucial. In some cases, replacing a motor in drilling applications can take up to ten hours or more. BEI Kimco Magnetics understands this need and has designed a motor that can stand up to the challenge, and has the testing results to prove it.

Burners benefit from reduced flame height and lower emissions

In traditional burners, oxygen and fuel has a small premix area before ignition (left). More premix time as introduced by Duplex technology (right) cuts the amount of pollutants generated each time the burner is lit.

Emissions regulations affecting heating units in refineries and steam generators have operators hunting for ways to cut greenhouse gases while maintaining the efficiency of their burners.
