| description | PCT No. PCT/SU80/00084 Sec. 371 Date Jan. 31, 1981 Sec. 102(e) Date Jan. 23, 1981 PCT Filed May 30, 1980 PCT Pub. No. WO80/02718 PCT Pub. Date Dec. 11, 1980.The present invention relates to the completion of wells and, more particularly, it relates to a method of drilling a productive bed. The herein disclosed method of drilling a productive bed comprises the tapping of the bed roof using a starting flushing fluid and the determination of the redox potential value at the moment of tapping the bed roof, and subsequent replacement of the starting flushing fluid with a fluid having redox potential value and sign equal to those of the productive bed rock. |
