Colorado DJ Basin WaterFrac Formulation

Colorado has a long history and significant ongoing activity in oil and gas development. Over two thirds of the counties in the state have active wells in them with over 26,000 wells in total statewide.

We are featuring typical fluid formulations for two of the most active basins; the Denver Julesburg (DJ) and Piceance Basins. The two DJ wells are typical of work done in Weld county where over 40% of the state's wells can be found. The Piceance well is representative of much of the work being carried out in Rio Blanco county.

* In certain cases, a small percentage of constituents may be protected under existing agreements with suppliers and customers. In these situations, CAS numbers are not listed – but the constituent's listing as hazardous on the MSDS is, as well as other common uses when identified.
** Items identified in the "common uses" column were chosen in part because the constituents found in these products exist in roughly the same concentrations as would be found in fracturing materials at the wellhead. In some cases, however, concentrations present in consumer products are either not publicly available or in higher percentages than would be found at the wellsite.
