Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, July 26–28, 2021
Paper Number: URTEC-2021-5646-MS
..., propped surface area, pressure depletion, and altered stresses due to parent well production were representative to the field conditions. The field-calibrated model was then used for sensitivity studies, varying the child well spacing and frac sequencing, to optimize pad productivity. Results were...

... microstructural alterations were observed after the HnP experiments. We observed an increase in the proportion of pore throat size between 3-10 nm radius and an increase in surface area by a factor of 2 in the Duvernay sample. SEM images also confirm MICP and BET observations where the organic matter pore size...

The preliminary results showed that the complex system yields the same or better performance compared to the simple fractures system scenario depending on the formation properties. Generally, the estimated area from RTA and PTA (production surface area PSA...

... to determine the pore changes due to CO 2 saturation. Barret Joyner and Halenda (BJH) model was employed to determine the pore structure distribution (pore size, pore volume and surface area) before and after CO 2 saturation. The results show that clay minerals and quartz increased whereas other minerals...
