| Summary: | The angular discordance of the Eocene that puts B sands of the Misoa Formation in contact with the La Rosa Formation affects, structure up, the thickness of the B6 member truncating it until eroding it in a northwesterly direction, with the presence of facies changes and local faults. With the objective of contributing to the recovery of gas reserves, a geological review was initiated to locate drainage points; the present investigation had the purpose of identifying the favorable stratigraphic and structural framework to locate in the upper part of the structure, monobore wells to drain the remaining reserves of gas from reservoir B6 LL 370, from the Tia Juana Lago field. It was established that plot A-226 is the most prospective for the establishment of drainage points for the drilling of monobore wells due to the best geological and reservoir conditions. Two locations are proposed (LL-Z-AB-AC-306-A4 and LL-AC-6-C5A1) to complete monobore with 5-1/2” pipe for a production potential of 2,8 MMPCND.
