Recovery of gas from drilling fluid returns in underbalanced drilling |
摘要 |
The drilling fluid returns from underbalanced drilling are introduced into a separator and a separate gas stream is recovered. The gas stream is cleaned at the well site to remove entrained liquid and particulate solids, to produce gas suitable to be fed to a compressor. The cleaned gas is compressed to re-injection pressure and recycled to the well.
