Title:  Unraveling the stratigraphic complexity of the Upper Miocene slope-channel systems at MP313, Gulf of Mexico Shelf: Leveraging reprocessed seismic to establish a new trend within a mature field.

Summary: 

Cantium began operating the GoM shelf MP313 field in 2017. A 2024 drilling campaign was launched to target a 25-acre amplitude anomaly in the H-10 Lower sand named Outforde. The target location was downdip from producers that went offline from low rates, high water cuts, or mechanical issues.

H-10 Sd fault block A production began in 1983 and totaled 3.1 MMBO and 4.1 BCF under water drive. Varying oil-water contacts, bottom-hole pressures, and drastic facies changes across the fault block alluded to complex drainage patterns. Our newly reprocessed seismic data revealed two distinct depositional episodes (Upper and Lower Members) of the H-10 sand package previously thought to be a single unit with multiple stratigraphic barriers. 

New data showed that the H-10 Lower member is divided into stratigraphically and structurally isolated NE-SW trending channel-form amplitude anomalies in eastern FB- A. Normalized AVA response curves from the reprocessed gather data showed Class III AVA response at the Outforde take point. Trap and charge were high risk elements as the prospect was heavily dependent on the geologic model and AVA analyses.  

Outforde discovered >100’TVT of net oil, approximately 2.5X Cantium’s pre-drill estimate.  Production began on 04/2024 and reached peaks rates of 1800BOPD. This has opened new development opportunities in neighboring amplitude anomalies for future drilling campaigns.
