WDTN18

WDTN18 is a well pad located in Battelle District, Monongalia County, WV. Drilling of the initial six (6) Marcellus wells was completed in 2023 before CNX launched Radical Transparency monitoring. Air monitoring began in June of 2024, ahead of hydraulic fracturing activity. These wells were transitioned to production in October of 2024 and were monitored through six months of production activity (Trip 1). Additional air quality monitoring commenced ahead of drilling six (6) additional Marcellus wells, which began in August of 2025. Hydraulic fracturing of these wells began in March of 2026 (Trip 2). These wells started production in September 2026.

Air Quality Monitoring

Upwind and downwind air quality monitoring equipment measuring PM2.5 (particulate matter) and VOCs known as BTEX was installed within 500’ of the well pad by a qualified third party, Clean Air Engineering.

The prevailing wind direction for this region is from the southwest. Clean Air Engineering positioned the PM2.5 monitors such that one would be subject to winds from upwind of the well pad and the other would be in the path of wind traveling across the well pad (downwind).

The Radical Transparency program includes monitoring of well pads in the construction, drilling, and completions phases of development through approximately 6 months of production. The first phase of air monitoring for this site was archived under the Radical Transparency program. Data from the archived, first phase is shown below.
