Canadian Dip-In DAS (CanDiD) Project 1
| Description: | The objective of the CanDiD-1 project was to acquire distributed acoustic sensing (DAS) data in a deviated wellbore during hydraulic fracturing operations in nearby horizontal wells, and thereby to characterize the subsurface strain and microseismicity that accompanied the growth of tensile fractures during well stimulation. The experiment took place in the Dawson Creek region of northeastern BC, Canada. As one of the first times that a temporary optical fibre was used for this purpose in Canada, a secondary technical aim of CanDiD-1 was to evaluate the effectiveness of a temporarily deployed fibre. The data were acquired using a DAS gauge length of 7.1 m and a spatial sampling interval of 1m, with a temporal sample rate of 1 kHZ. A fibre optic cable was deployed from the wireline truck and tractor to a measured depth of 4300m into a deviated well. The raw strain observations were acquired in a proprietary data format and have been converted to .hdf5 data format, which can be read using the open source package h5py (https://www.h5py.org). |
