Deterministic fracture network models from the Potiguar basin, Brazil

Fracture patterns observed in the Jandaira carbonate formation (Potiguar basin, NE Brazil), digitised using a drone and manual interpretation in DigiFract software. These patterns are translated to a local coordinate system to allow for easier implementation in flow models, and each fracture has its attributes stored, including length, spacing, orientation and aperture calculated using different models. Data is stored in two formats: - Shapefiles (open with open-source QGIS, matlab shaperead, and several python modules including basemap). - Google kml files (open with Google Earth)巴西东北部波蒂瓜尔盆地（Potiguar basin）詹代拉碳酸盐岩地层（Jandaira carbonate formation）中观测得到的裂缝样式，通过无人机采集数据，并借助DigiFract软件（DigiFract）开展人工解译后完成数字化。为便于在流动模型中更便捷地应用，已将上述裂缝样式转换至局部坐标系；每条裂缝的各项属性参数均已存档留存，包括采用不同计算模型得到的裂缝长度、间距、方位（orientation）与开度（aperture）。 数据集以两种格式存储： - 形状文件（Shapefiles）：可通过开源软件QGIS、Matlab的shaperead工具，以及包含basemap在内的多个Python模块打开读取； - Google KML文件：可通过谷歌地球（Google Earth）打开查看。
