Abstract
Official abstract text for this publication.
A method of drilling into a geological region including a subsurface clathrate reservoir includes drilling a borehole into the geological region including the subsurface clathrate reservoir and dissociating at least a portion of the clathrate in a region near the borehole. After the dissociating, material within at least a portion of the region near the borehole in which the clathrate has been dissociated is compacted to form a compacted region at least partially surrounding the borehole within the clathrate reservoir. After the compacting, well casing is placed into the borehole within the compacted region and the well casing is cemented into the borehole in the compacted area.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of drilling into a geological region including a subsurface clathrate reservoir, comprising: drilling a borehole into the geological region including the subsurface clathrate reservoir; dissociating at least a portion of clathrates in a region near the borehole; measuring an amount of gas, fluids, or both generated during the dissociating to provide a measured amount, comparing the measured amount to a baseline, and using the measured amou…
