Abstract

A multi-layer composite synthetic test bed may be used to model fracture propagation and fracture networks. For example, a fracturing fluid may be introduced into a multi-layer composite synthetic test bed at a pressure and a flow rate sufficient to create a fracture network therein. Then, the fracture network may be analyzed to produce synthetic fracture data, which may be used in a fracture model.

forming a multi-layer composite synthetic test bed comprising a plurality of layers in an alternating configuration that corresponds to the selected rock lithology using the materials of construction, the multi-layer composite synthetic test bed being configured to fracture in a manner that corresponds to downhole fracturing in the corresponding subterranean formation based on the selected rock lithology, the materials of construction comprising at least one polymer and an additive;
introducing a fracturing fluid into the multi-layer composite synthetic test bed at a pressure and a flow rate sufficient to create a fracture network therein;
obtaining imaging data indicating a fracture propagation in the fracture network from one or more sensor devices coupled to the multi-layer composite synthetic test bed; and
producing synthetic fracture data based on the obtained imaging data.

2. The method of claim 1 , further comprising: inputting the synthetic fracture data into a fracture model.

3. The method of claim 1 , further comprising: using the fracture model to design a fracturing operation of the corresponding subterranean formation.

5. The method of claim 1 , further comprising: adjusting a temperature and a pressure of the multi-layer composite synthetic test bed.

6. The method of claim 1 , further comprising: correlating the synthetic fracture data to actual fracture data of the corresponding subterranean formation to produce correlated fracture data that maps the synthetic fracture data to fracture parameters of the actual fracture data.

7. The method of claim 6 , further comprising: inputting the correlated fracture data into the fracture model.

8. A method comprising:
determining materials of construction that correlate to properties of a selected rock lithology for a corresponding subterranean formation;
forming a multi-layer composite synthetic test bed comprising a plurality of layers in an alternating configuration that corresponds to the selected rock lithology using the materials of construction, the multi-layer composite synthetic test bed being configured to fracture in a manner that corresponds to downhole fracturing in the corresponding subterranean formation based on the selected rock lithology, the materials of construction comprising at least one polymer and an additive;

(1) mapping the fracture network to produce (A) a map of the fracture network;
(2) analyzing a birefringence in a material of the multi-layer composite synthetic test bed surrounding at least a portion of the fracture network to produce (B) a stress of the material associated with the birefringence; and
