Sonoro Energy Ltd. (“Sonoro” or “the Company”) (TSX-V: SNV), hereby provides an update to drilling operations at its LG-1 Up-dip well on the Budong Budong Production Sharing Contract (“PSC”) in West Sulawesi, Indonesia.
Coring operations retrieved 27.4 meters of core from depths of 296.0m to 326.9m (90% core recovery). Operations were subsequently switched over to conventional drilling on Saturday, Nov. 4, and proceeded to a total depth of 549m. Logging operations are now under way.
In the core and drilled section, several thin sands ranging between 0.2 to 1.4 meters estimated, were observed with oil and gas shows. Some of the sands were described by an onsite Sonoro geologist as “fast streaming cuts, visible fair porosity, medium to fair sized grains, poorly cemented and good oil shows.” Subsequent core analysis is being considered to provide more technical information on these sands.
Drilling operations were switched to a conventional 61/8″ bit after coring proved to be challenging due to higher required mud weights as a result of overpressures and gas encountered. Conventional drilling proceeded efficiently with good hole conditions to a final depth 549.8m.
Strong oil and gas shows were encountered across various interval from 280.0 to 549.8m, with multiple sands seen interbedded between clay and siltstones. Until logging and drill stem tests (“DSTs”) are undertaken, it is too early to make conclusions.
Logging operations from the well are now underway to provide further information on the sands and oil and gas shows encountered. Should log interpretations be encouraging, Sonoro may then proceed to performing DSTs on specific sands to determine indicative potential rates, pressure and other information.
“The discovery of strong oil and gas shows in the recovered cores, mud, and observed cuttings are strong evidence of a petroleum system being present. Additionally we are seeing better quality reservoir sands in the LG-1 Up-dip versus the previous LG-1 well. Following logging and testing, we will be able to better assess all the available information to determine further prospectivity on this structure and extrapolation to the numerous other targets within the Budong Budong PSC,” said Sonoro’s Chief Executive Officer and Director Richard Wadsworth.
Further details will be provided once the above information is assessed in conjunction with logging and testing results.
