Cabot Oil & Gas has jumped on the natural gas-powered drilling rig bandwagon. Yesterday, Cabot announced they have begun using “field gas”–Marcellus Shale gas from the very wells they’re drilling–to help power the drilling rigs they’re using to drill for the gas. According to Cabot, this is the first time field gas has been used in drilling rigs in northeastern PA. Cabot is using Caterpillar engines that run on duel fuel technology–part natural gas, part diesel.
You may recall other Marcellus drillers are also using duel fuel, and some are using 100% natural gas, to power their rigs. Those companies include EQT, CONSOL, Seneca Resources and Antero Resources (see Antero Res 2nd Marcellus Driller to Use 100% NatGas Rig Engines for a description of other drillers’ efforts to date). The unique aspect of Cabot’s announcement is that they’re using field gas and not trucking in LNG to power their duel fuel engines. It means far fewer truck trips to the drill site.
