OJAY - CADOTTE / FALHER DEVELOPMENT POTENTIAL
CADOTTE AND FALHER GEOLOGY OVERVIEW
Cadotte: The Cadotte Formation forms a well-sorted, coarsening upwards progradational-barrier bar sequence that transitions northward into offshore interbedded silts and thin sands. Sediments range in size from very fine sandstone to conglomerates, and are primarily comprised of quartz and chert with authigenic components including siderite, calcite, chlorite, and mixed-layer illite-smectite. Erosional scour surfaces exist internally, separating lower to middle shoreface fine- to very fine grained-sandstones, from upper shoreface and foreshore coarser sandstones and conglomerates.
Falher: The Falher Formation is the middle member of the Spirit River Group, and was deposited overall as a reworked progradational stack of coarsening upwards deltaic and barrier bar sequences, influenced by marine processes along a high energy east-west trending shoreline. The Falher can be divided into multiple units. Coarser-grained sandstone and conglomeratic facies form potential reservoirs, which were deposited within wave-dominated upper shoreface and foreshore environments. Finer-grained sandstones, mudstones, and siltstones form the non-reservoir, quality facies that were deposited within lower shoreface, tidal inlet, back-barrier, and coastal plain settings.
CADOTTE AND FALHER DEVELOPMENT POTENTIAL
In the Ojay area, both the Cadotte and Falher form a fairway that cuts across Company lands in a southeast to northwest direction. Both reservoirs are influenced by faulting, increasing connectivity and therefore wellbore productivity. Both the hanging and footwall along the identified faults are targeted, where folding caused by the thrust faults develop open fracture systems at maximum curvature points. Currently ten locations have been identified targeting the Cadotte, four locations targeting the Falher, and four locations targeting both the Cadotte and Falher zones. One dual zone well, c-003-H/093-I-15 has Probable Additional reserves booked.
