An organic geochemical investigation of the carboniferous Mabou Group intersected by groundwater wells in McCully Gas Field, southern New Brunswick - its hydrocarbon source potential and character / C.... : M183-2/8071E-PDF

"Water wells were drilled in November 2015 over the McCully gas field in southern New Brunswick as part of the Geological Survey of Canada (GSC) Environmental Geoscience program. Drill cuttings were collected and immediately put in Isojars at the well sites. Cuttings samples from PO-01 to PO-06 wells have been submitted to the Organic Geochemistry and Petrology Laboratories at the GSC-Calgary for Rock-Eval and hydrocarbon compositional analyses to evaluate their hydrocarbon potential, hydrocarbon property and source rock characteristics. Cuttings from one well (PO-06) have generated results indicative of presence of organic matter and hydrocarbons in the rock although no dissolved hydrocarbons were detected in groundwater at the well site. New Rock-Eval analyses were carried out on the cuttings as well as organic extracts and detailed geochemistry to further address the issue of either in situ hydrocarbon production or external hydrocarbon charge into the sediments"--Abstract, page 1.
