Caterpillar Oil & Gas sells 700th Dynamic Gas Blending kit
HOUSTON -- Caterpillar Oil & Gas has reported the sale of the 700th Cat Dynamic Gas Blending (DGB) kit for 3500 engines, the company’s industry-leading dual fuel technology for land drilling, production and well stimulation applications. Originally introduced to the market in 2012, the CARB certified Cat DGB retrofit kits have become the industry’s chosen dual fuel system, operating in global oilfields ranging from the U.S. to China. The 700th kit will be installed on a Cat 3512C land electric drive drilling module rated at 1,045 ekW (1,467 bhp) @ 1,200 rpm.
The Cat DGB system for land drilling, production and well stimulation achieves maximum substitution of diesel fuel with natural gas during operations. Along with the benefit of realizing significant fuel cost savings by substituting diesel fuel with natural gas, there are several other key features of the Cat DGB system that make it a winning solution for the oilfield. Operators can run the system with confidence on CNG, LNG, and a wide range of field gas, knowing that the engine is maintaining U.S. EPA Tier 2 level emissions with the Cat Diesel Oxidation Catalyst (DOC) included in the DGB kit. The system automatically adjusts to changes in gas quality without the need to perform any recalibration or adjustments to the system during or between jobs.
The Cat DGB kit for land drilling and production also includes an EMCP 4.4 panel as standard equipment. In addition to handling routine generator functions such as paralleling and load sharing, the EMCP 4.4 can automatically start and stop generators based on overall rig power demand. “The EMCP 4.4 can dramatically improve owning and operating costs on a drilling rig by reducing unnecessary engine run time and keeping the engines in their sweet spot for fuel economy and gas substitution,” Bohlmann noted.
The Cat DGB solution for well stimulation applications is available in Air To Air After Cooled (ATAAC) and Separate Circuit After Cooled (SCAC) configurations for 2,250 hp and 2,500 hp @1,900rpm ratings.
