... Abstract This study focuses on the reservoir characterization of four geological formations in Alberta, Canada: the Cadomin Fm., Baldonnel Fm., Montney Fm and Belloy Fm. Among these formations, the Montney Formation is targeted for gas production, while the Cadomin and Baldonnel formations...

... a severer deviation of child-fractures towards the parent wellbore, resulting in more substantial well interference and less desirable oil and gas production. The parent-child fracture overlapping ratio in our study is in 0.6 ~ 0.8 for the 400 ft horizontal offset and 0.2 ~ 0.5 for the 600 ft horizontal...

... f , defines the productivity and economic viability of gas wells. Most researchers explain enhancements of gas production from shales by invoking slip flow in the nanopores at high Knudsen number, Kn. However, molecular gas dynamics simulations, experimental results in carbon nanotubes...

... Abstract The gas/oil ratio (GOR) of unconventional wells in the Midland Basin is becoming an increasingly important topic, due to both transportation capacity and the general price conditions for gas products. Coupled with this, interwell spacing tests have caused many to rethink the economic...

..., we incorporated the propped fracture geometry and conductivity distribution into a reservoir simulation model to predict gas production. Based on the field designs of pumping schedules in slickwater treatments, we have generated four proppant schedules, in which 100-mesh and 40/70-mesh proppants were...

The simulation result duplicates this phenomenon, as shown in Figure 6(c). Fu et al. (2019) presented semi-log plots...

... operations were successful indicating that the new method is operationally feasible. In comparison, two offset wells were fractured one of which was with energized crosslinked gel and another with slick water/crosslinked gel system. The two offset wells did not have gas production after flowing back...

... Abstract Hydraulic fracturing is a well stimulation technique for improved natural gas production from tight gas and shale formations. However, the implementation of the technique brings in new formation damage considerations. During the fracturing treatment, a large volume of water is pumped...
