三十年页岩气开发过程中，我们学到了什么？

发一篇SPE 综述，还是很全面的一篇资料，摘要如下：
The first lessons from this study are:
• No two shales are alike. Shales vary aerially and vertically within a trend, even along the wellbore.
• Shale “fabric” differences, combined with in-situ stresses and geologic changes are often sufficient to require
stimulation changes within a single well to obtain best recovery.
• Understanding and predicting shale well performance requires identification of a critical data set that must be
collected to enable optimization of the completion and stimulation design.
• There are no optimum, one-size-fits-all completion or stimulation designs for shale wells.

SPE标题：Water Fracs and Sand Quantity: A Barnett Shale Example
摘要：Chief Oil and Gas, LLC has an active drilling and completion
program in the Barnett Shale, Newark East Field, Ft Worth
Basin near Ft Worth, Texas, USA. This Mississippian age gas
producing reservoir consists of naturally fractured shale. Most
hydraulically induced fractures have been observed to be more
of a network of fractures, referred to as fracture fairways, than
the usual ‘planar’ fractures. These fairways apparently result
from opening many of the natural fractures allowing for
production. All wells must be hydraulically fractured for
economic production. The Barnett Shale hydraulic fracturing
trend in the last few years has been to water frac with small
concentrations of sand. The water frac treatments reported on
here have varied from approximately 600,000 to over
1,500,000 gallons and 120,000 to over 400,000 pounds of
sand. Most of the wells have been completed in the lower
Barnett with a lesser number in the upper and lower. Results
from both types of completions are included in this work.
Production histories versus treatment volume and pounds of
sand are presented as well as production decline data. Results
indicate a much better correlation of production history with
sand quantity than with fluid volume.
