据世界石油8月16日报道称，2018年6月，位于德克萨斯州东北部和路易斯安那州的海恩斯维尔（Haynesville）页岩地层的天然气产量平均为6.35亿立方英尺，占美国干燥天然气总产量的8.5％，是Haynesville自2012年11月以来的最高水平。
海恩斯维尔页岩层位于深度10,500英尺到13,500英尺之间。相比之下，马塞勒斯页岩的深度介于4,000英尺到8,500英尺之间。这个深度使得海恩斯维尔页岩的钻探成本普遍高于其他页岩层。 然而，近年来盈亏平衡成本有所下降，使海恩斯维尔的天然气在当前价格水平上具有经济效益。

EIA: Haynesville natural gas production reaches five-year high
In June 2018, natural gas production in the Haynesville shale formation, located in northeastern Texas and Louisiana, averaged 6.35 Bcfd, accounting for 8.5% of the total U.S. dry natural gas production, Haynesville’s highest production level since November 2012.
The Haynesville formation lies deep underground between 10,500 ft and 13,500 ft. In comparison, the depth of the Marcellus shale ranges between 4,000 ft and 8,500 ft. This depth makes drilling costs in the Haynesville shale generally higher than other shale plays. However, breakeven costs have decreased in recent years, making Haynesville natural gas economic at its current prices.
