Episodic fracturing is discussed in relation to both sedimentary deposition rates and lithology, as well as to pressure release criteria and vertical numerical grid sizes of a one‐dimensional fluid‐flow/ compaction model. It is shown that the evolution of episodic fracturing is a ruggedly stable pattern for fine‐scale gridding, and that a critical fracture pressure of around 0.8 of the lithologic overburden is suggested.
