Oklahoma City-based oil and gas producer Chesapeake Energy reduced its corporate fleet accident rate by almost one accident per million miles driven in 2013, according to the company.

During the year, Chesapeake trained more than 4,600 employees with its safe driving program and implemented a fleet management system that provides real-time alerts to drivers when they exceed predetermined speeding, acceleration or hard-braking limits.

"These alerts serve as a remote driving coaching solution by reminding our fleet drivers to practice safe-driving habits," according to the company's 2014 Corporate Responsibility report.

In 2013, Chesapeake recorded a rate of 2.08 accidents per million miles driven, which was down from 2.92 accidents per million miles in 2012.

Chesapeake's mostly truck fleet consists of 5,619 vehicles, including Class 1-2 pickup trucks, Class 3-6 trucks, and cars. Chesapeake operates 1,707 compressed natural gas vehicles. In 2013, fleet vehicles used 6.9 million gallons of gasoline and 2 million GGE of CNG, which accounted for 22 percent of total fuel usage, according to the report.

Chesapeake is the second-largest natural gas producer in the U.S. with leading positions in the Eagle Ford, Utica, Granite Wash, Cleveland, Tonkawa, Mississippi Lime, Niobrara unconventional liquids plays as well as in the Marcellus, Haynesville/Bossier and Barnett natural gas shale plays.
