Compressional and shear sonic traveltime logs (DTC DTS, respectively) are crucial for subsurface characterization seismic-well tie. However, these two often missing or incomplete in many oil gas wells. Therefore, petrophysical geophysical workflows include log synthetization pseudo-log generation based on multivariate regression rock physics relations. Started March 1, 2020, concluded May 7, the SPWLA PDDA SIG hosted a contest aiming to predict DTC DTS from seven “easy-to-acquire”...

Abstract Various wellbore completion strategies have been developed for thermal wells in Western Canada. The idea this paper is estimating the improvement of oil production and steam injection if flow control devices (FCDs) will be installed next to drilled, or FCDs were at a particular well-pad that has not yet completed with any FCDs. approach based on labeled real data 68 well-pads from seven major projects Three phases make up paper's methodology. first phase compares without evaluate...

Abstract In steam-assisted gravity drainage (SAGD) operations, inflow control devices (ICDs) might provide an extra pressure drop (ΔP) on top of the liquid pool's ΔP. To avoid hot-spot zones, this ΔP design heavily relies reservoir quality. Flow-loop experiments can flow قate measurements versus for various nozzle designs. Therefore, efficient ICD should be investigated in a numerical simulation that represents quality and heterogeneity by employing flow-loop data. study, core analysis 40...
Abstract Pursuing more cost-effective well construction and reduced surface footprint has prompted Western Canadian operators to explore extreme extended reach drilling (ERD) wells. However, this endeavor faces a critical challenge: most heavy oil reserves are relatively shallow, resulting in the unwrapped ratio (the total horizontal length when projected on plane true vertical depth (TVD)) of than seven. Therefore, drill ERD wells, two crucial technical challenges must be tackled:...

SAGD pad using maximum possible well-length has taken significant leaps in economical assessment projects. goal this...
Summary Designing and selecting the proper sand control mechanism for horizontal wells in unconsolidated heavy-oil reservoirs tend to be underlooked some cases. Standalone completions pose challenges, which could jeopardize oil production or even lead critical problems. Massive production, screen/formation plugging, hot spots, mechanical integrity failures are of well-known issues. This study attempts optimize slotted liner design a field Colombia.

Abstract NCG is increasingly being co-injected with steam in heavy oil production systems to reduce heat loss and greenhouse gas emissions, as well maintain reservoir pressure. Given increased use of co-injection, the validity conventional subcool models must be revisited since they assume that chamber comprised water alone. The current study makes modifications pure-steam hydrostatic model, Yuan & Nugent (2013) model account for presence chamber. Using typical values from Athabasca...
