Collecting borehole data for reservoir characterization

Borehole seismic data collected during and after the drilling of exploration and appraisal wells delivers valuable information for reservoir characterization. 结合地面地震资料, borehole seismic surveys can help calibrate results and improve your predictions, as well as image specific reservoir features around the borehole. Drillpipe-conveyed systems are used to collect information on seismic velocities while drilling and to predict lithological changes ahead of the bit. Wireline-conveyed tools and systems are used to acquire high-resolution seismic images in and beyond the borehole.

Many subsurface 成像 problems cannot be solved without a 3D survey, and when a survey also needs to be performed in the borehole, 解决方案是3D 垂直地震剖面(VSP)技术. 我们的新 Optiq地震 fiber-optic borehole seismic solution reduces VSP acquisition time from the hours required by conventional seismic operations to just minutes.
