The burial depth, formation pressure coefficient, and residual formation pressure of the target in Dingye-1 and Dingye-2 Wells in the Dingshan block. See Figure 1 for the well locations.

Structural type	Well	Depth (m)	Formation pressure coefficient	Shale gas production (×10^4 m^3/t)	Residual formation pressure (MPa)
Anticline	Dingye-1	2125.76	1.08	3.45	1.67
Syncline	Dingye-2	4417.43	1.55	10.5	23.81
