... closely tied to the business scale and success. One first order driver of financial results is the tradeoff between well density and completions intensity which involves assumptions about producing reservoir volume and completed reservoir volume. The complexity of unconventional reservoirs prevents...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 13–15, 2023
Paper Number: URTEC-3864951-MS
... Abstract As the number of greenfield and brownfield development opportunities dwindle, many operators are looking to refracture older existing wells for additional hydrocarbon production. While it is generally understood that a bigger second completions job will yield more oil production...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 13–15, 2023
Paper Number: URTEC-3868861-MS
.... To increase production, they adopted infill drilling and completion techniques to increase the stimulated reservoir volume and increase production. However, drilling these wells close to each other has resulted in interference of production known as fracture-driven interactions (FDI) between the wells...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 13–15, 2023
Paper Number: URTEC-3871063-MS
... Abstract Flow regime changes are important to capture and predict when estimating the future production from tight oil wells. Due to the nature of hydrofracture completions and reservoir heterogeneity, flow regimes are difficult to predict before they are observed. Also, while some wells...

... due to wet zone completion. Rather, the increasing water cut trend is mostly because of improved completion methods, increased well density, and aggressive production techniques that speed up fluid withdrawal rates. Without pressure maintenance from injection, gas cap expansion, or aquifer influx...
