得克萨斯州沃斯堡盆地的纽瓦克东部(Barnett Shale)气田目前是得克萨斯州日产量最高的气田，年增长率超过10%。然而，尽管多年来来自多家公司的非常有能力的地质学家和工程师对巴尼特气藏进行了深入的研究，但对于控制德克萨斯州北部巴尼特气藏成功的根本因素，仍然存在几个误解。巴尼特气藏在断层和构造挠曲(背斜和向斜)附近地区的产量较差。裂缝在这些构造环境中最为丰富，不利于巴尼特油田的生产。开放的天然裂缝在巴尼特地区很少见，与巴尼特的产能几乎或根本没有关系。在巴尼特页岩热成熟的地区，天然气生成略有超压(约0.52psi/ft[11.76kpa/m])。巴尼特组内的石灰岩层是泥石流的产物，泥石流起源于现今盆地中心以北的碳酸盐陆架。看来，巴尼特可以作为其他盆地的勘探模式，特别是瓦奇塔趋势的类似盆地。德克萨斯州北部巴尼特油藏的开发历史为坚持如何在非常规领域取得成功提供了一个很好的例子。加油站。
Newark East (Barnett Shale) field, Fort Worth Basin, Texas, is currently the most productive gas field in Texas in terms of daily production and is growing at an annual rate of more than 10%. However, despite the fact that the Barnett play has been studied intensely by very capable geologists and engineers from several companies over a period of many years, there continues to be several misunderstandings concerning fundamental factors controlling the success of the Barnett play of north Texas.Barnett gas production is poorer in areas near faults and structural flexures (anticlines and synclines). Fractures, which are most abundant in these structural settings, are detrimental to Barnett production. Open natural fractures are rare in the Barnett and have little or nothing to do with Barnett productivity. In areas where Barnett Shale is thermally mature with respect to gas generation, it is slightly overpressured (about 0.52 psi/ft [11. 76 kPa/m]). Limestone beds within the Barnett formation are the product of debris flows that originated on a carbonate shelf to the north of the present basin center. It appears that the Barnett can be used as an exploration model for other basins, especially analogous basins of the Ouachita trend.The history of the development of the Barnett reservoir in north Texas provides an excellent example of how persistence can lead to success in nonconventional. gas plays.
