Appendix A: MFrac Simulation Graphs

Figure A1: The Fracture Length 600 ft and Width from 0.05 to 0.55 in Width Contours.

The fracture length and width contours as shown in Figure A1. with different colours as they appear in the

upper right corner represent the width ratio for each segment of the width. Each colour represents a segment

ratio of the whole width.

Figure A2ERROR! NO TEXT OF SPECIFIED STYLE IN DOCUMENT.: The Fracture Efficiency versus Time.

Figure A2 was produced using MFrac, and it represents the efficiency of fracturing against time. The efficiency

decreases with time.
