... demonstrated a satisfactory result paving the way for field-wide execution in the field. The large-scale polymer injection pilot has been carried out from September 2019 – August 2021 with 12 polymer injectors and 20 producers. Both technical and operational data were thoroughly analyzed during the pilot...

The optimizer iteratively reallocates the well rates, diverting the injected fluid to high efficiency injector-producer...

... Treatments To retard or eliminate water movement and channeling, three chemical treatment methods have been practiced in the industry for over half a century: Emulsion injection into water-producing zone, which involves injection of an emulsion (e.g., paraffin-in-diesel) into water-producing zone...

It provides a roadmap...

... (StoSAG) and reservoir-simulations runs for a synthetic example considering a three-layer, channelized reservoir with 4 injectors and 9 producers. Results show that the proposed LS-SVR-based optimization framework is at least 3 to 6 times computationally more efficient, depending on the cases considered...

... injection. A separately designed wellbore tractor specific for both fluid detection and valve manipulation is then deployed to detect and control the injection entry points to create an effective EGS through paired horizontal injectors and open hole producers. The wells will be connected through multiple...

... producers to other producers within the new patterns. A lower surfactant dosage was applied to one of the new patterns to optimize chemical consumption, while sustaining the performance. The surfactant concentration was also reduced in the first pattern to study the effect of a lower dosage on a known...

... Abstract The use of CO 2 injection to produce oil from the residual oil zone (ROZ) of the Wasson field in the Permian Basin has proven to be highly successful when an appropriate development plan is used. The significant volume of oil in place in the ROZ presents a large target for both...
