This paper reports on microfracturing with nitrogen, an experimental extensometer, stress profile determination from wire line logs, and temperature logging in air-filled holes which are new tools and techniques that add resolution to Devonian shale gas well analysis. Microfracturing creates small fractures by injecting small amounts of fluid at very low rates. Microfracs are created usually at several different depths to determine stress variation as a function of depth and rock type. To obtain and oriented core containing the fracture, the formation is microfractured during drilling. These tests are critical in establishing basic open hole parameters for designing the main fracture treatment.
