Waseca Formation Wells (Kerrobert, SK)

In June 2023, Sonoro announced it had signed a farm-in agreement with partner Superb Operating Company in pursuit of an exciting opportunity in the Western Canadian Sedimentary Basin, where a proven heavy oil resource fairway and well productivity are well-defined.

First oil at Sonoro’s 14-29 well

Sample of first oil—specifically, CHOPs (Cold Heavy Oil Production with sand)—from our 14-29 multilateral horizontal well near Kerrobert, SK, in January 2024.

After securing a drilling rig and services, and obtaining the necessary license from the Saskatchewan Ministry of Energy and Resources, Sonoro drilled a multilateral horizontal well on the property near Kerrobert, SK in mid-December 2023, with 4 horizontal legs for a total lateral length of approximately 1,600 metres.

Preliminary strip log and sample reports indicate that the Waseca sands encountered in the lateral sections of the 14-29 well were very good, with intergranular porosity sandstone exhibiting strong petroliferous odor and abundant oil staining, along with heavily concentrated oil cut drilling fluid recovered at surface.

Production commenced in January 2024 via a Cold Heavy Oil Production with Sand (CHOPS) process typical of the area, and as of February, we made our first oil sales from the 14-29 well.

The innovative multilateral horizontal well technology utilized in this well was developed in collaboration with Modern Wellbore Solutions—a strategic advancement that’s now been proven to enable the installation of slotted liners at multiple junction points within a single well, allowing for unparalleled access to multiple reservoir sections from one vertical well bore. This technologically advanced drilling technique is expected to boost production rates and maximize reserves.

Says Sonoro CEO Richard Wadsworth: “We are enthusiastic to have this well placed on production (and) see an expected higher well productivity resulting from this reservoir, multilateral well strategy and technology.”

Well 11-30-32-23 W3

The site of Sonoro’s first well near Kerrobert, SK, drilled in mid-November 2023.

Sonoro also drilled a vertical development well in November 2023, about 1.5 km away from the 14-29 well.

This well, with a planned total depth of about 900 metres, targets the same Waseca channel sand in which Baytex’s operating Kerrobert field is located—a field currently producing more than 1,800 barrels of heavy oil per day.

Sonoro’s inaugural well also directly offsets three Baytex wells that have produced more than 252,000 barrels.

This well presents a low-risk, step-out location that can be immediately brought into production.
