传统上，从煤层开采天然气的经济吸引力取决于适当的井距和增产措施。为了提供这一经验证据的分析基础，进行了油藏模拟和经济分析，以深入了解阿拉巴马州橡树树林油田典型良好和恶劣地质环境下的最佳井距和水力压裂处理。作者报道了他们对基于凝胶的压裂处理的经济效益、高渗透率和低渗透率环境下的最佳井距，以及如何确定合适的渗透率值和最佳井距可实现的水力压裂尺寸的研究。
Conventionally, proper well spacing and stimulation govern the economic attractiveness of producing natural gas from coalbeds. To provide an analytical foundation for this empirical evidence, reservoir simulation and economic analyses were conducted to gain insights into the optimum well spacing and hydraulic-fracturing treatments in typical good and poor geologic settings of the Oak Grove field in Alabama. The authors report their study of the economic benefit of gel-based fracturing treatments, the optimal well spacing for higher- and lower-permeability settings, and how to establish proper values for permeability and achievable hydraulic-fracture dimensions for optimal well spacing.
