Test proppants to mitigate respirable dust hazards ///

Horizontal drilling and multi-stage fracturing allow economical extraction of oil and gas resources from unconventional plays. With unprecedented growth in the last 10 years, the industry recognizes that sustainable growth is possible, only by the implementation of proven and environmentally safe solutions. Development of unconventional resources increases proppant consumption, and the amount of proppant used per wellsite was over 10 times higher in 2013 than in 2004. In 2014, wells utilizing 10 million lb of proppant/well are no longer an exception, but the new norm. Today, industry-accepted proppant qualification standards focus only on the mechanical strength and conductivity of proppants, as described in API 19-C and API 19-D testing procedures. Safety associated with proppant handling is not a part of those industry-accepted proppant selection requirements.
