作为巴内特协调活动的一部分，我们对德克萨斯州巴内特页岩地区石油和天然气生产井场设施的甲烷排放量进行了研究，使用创新的地面移动的通量平面（MFP）测量系统进行测量。1我们仅使用公共道路，于2013年10月测量了近200个井场在两周内的排放量。测量的井场的总体被分成具有可检测排放的井场（N = 115）和具有低于MFP仪器的检测限的排放的井场（N = 67）。对于非零排放的井场，分布高度偏斜，几何平均值为0.63 kg/h，几何标准差为4.2，算术平均值为1.72 kg/h。包括非排放井场的人口，我们发现本研究中采样的井场的算术平均值为1.1 kg/h。该分布意味着50%的排放是由于6.6%的最高排放井垫，并且80%的排放来自22%的最高排放井垫。
We present a study of methane emissions from oil and gas producing well pad facilities in the Barnett Shale region of Texas, measured using an innovative ground-based mobile flux plane (MFP) measurement system, as part of the Barnett Coordinated Campaign.1 Using only public roads, we measured the emissions from nearly 200 well pads over 2 weeks in October 2013. The population of measured well pads is split into well pads with detectable emissions (N = 115) and those with emissions below the detection limit of the MFP instrument (N = 67). For those well pads with nonzero emissions, the distribution was highly skewed, with a geometric mean of 0.63 kg/h, a geometric standard deviation of 4.2, and an arithmetic mean of 1.72 kg/h. Including the population of nonemitting well pads, we find that the arithmetic mean of the well pads sampled in this study is 1.1 kg/h. This distribution implies that 50% of the emissions is due to the 6.6% highest emitting well pads, and 80% of the emissions is from the 22% highest emitting well pads.
