The Mississippian Alida in southeast Saskatchewan has produced substantial hydrocarbons at sub-crops for many years. Most recent development focuses on open hole horizontal drilling and delivers some of the best economics in the WCSB.
Deposited on a broad carbonate shelf, the Alida shows best reservoir potential in local buildups that develop packstone/grainstone shoals. These oil pools occur on local structural highs at or near the Alida subcrop edge.
Alida wells are often characterized by high initial rates and moderate declines.
