Questar Baseline Announces Instrument Sale to Halliburton Co.
-- Instrument Packages To Be Part of Innovative Monitoring System

LYONS, Colo. — Questar Baseline today announced the sale of eighteen 8000-Series gas-analysis systems to Halliburton Company and its subsidiary, Sperry-Sun Drilling Services. The 800-Series systems, which will be used for mud logging, are to be integrated into Sperry-Sun's Rigsite Network, a revolutionary data-collection method that provides oil-well information for remote real-time analysis.

     Through a variety of sensors at the rig, Sperry's Rigsite Network can remotely monitor drilling operations over the Internet. The Windows-based system can simultaneously display real-time and historic data, enabling the user to make more timely and accurate drilling decisions.

     "Sperry needed a rugged, compact system that stood up to the physical demands of a drilling rig," said Baseline western region sales manager Chuck Slicker. "The digital interface of the 8000 Series made for excellent integration into the Sperry network as well."

     Baseline's 8800 Gas Analyzer and 8900 Gas Chromatograph will work in tandem at the well site to automatically monitor gases brought up in the drilling mud and alerting the drilling operators when they are close to a discovery. The instruments also serve as a safety mechanism for the drilling-rig workers, automatically setting off an alarm if dangerous gases are present in the mud.

     Shipments of the Baseline 8000 Series systems will begin immediately and continue through late summer 2000. 

     Questar Baseline is a subsidiary of Salt Lake City-based Questar InfoComm Inc. (Questar InfoComm Inc. is a wholly owned subsidiary of Questar Corp., a $2.3 billion diversified natural gas company headquartered in Salt Lake City.)
