Geology Quality: A Method of Using 3D Geology Model Data for Completion and Fracturing Optimization in Horizontal Wells

Asia Pacific Unconventional Resources Symposium, 2023
Abstract Engineered completion designs consider reservoir quality (RQ) and completion quality (CQ) for horizontal well completion optimization. This is more effective than the geometric strategy that is sometimes used. However, both RQ and CQ are derived from the wellbore logs, which means the true geology and reservoir properties inside

The geology of the oceanographer fracture zone: A model for fracture zones

Journal of Geophysical Research, 1976
An unreversed refraction experiment located 325 km west of the center of the Oceanographer transform and aligned along the axis of the fracture zone yielded information on the velocity structure of the crust within the fracture zone axis. A layer 2 km thick having a compressional wave velocity of 4.4 km/s overlies a layer with a compressional wave ...

Study of Geology-Engineering Integration Fracturing Design Based on Material Point Method

2021
Due to terrestrial deposited, the tight-oil-reservoir in North Songliao Basin has strong heterogeneity. In view of this characteristic, this paper studied on geology-engineering integration based on material point method, and confirmed reasonable parameters and fracturing models, to increase the efficiency of volume fracturing.
