Effect of pressure systems on the development effectiveness of 125m polymer blocks [PDF]

open access: yesE3S Web of Conferences, 2022
Since the industrial polymer drive development in the oilfield, eight blocks have experienced polydrive development successively. With the extension of the development time, the extraction well spacing of polymer drive blocks has been reduced.

Optimization of Fracture Spacing and Well Spacing in Utica Shale Play Using Fast Analytical Flow-Cell Model (FCM) Calibrated with Numerical Reservoir Simulator

open access: yesEnergies, 2020
Recently, a flow-cell model (FCM) was specifically developed to quickly generate physics-based forecasts of production rates and estimated ultimate resources (EURs) for infill wells, as the basis for the estimation of proven undeveloped reserves.

Investigation of the Effect of Natural Fractures on Multiple Shale-Gas Well Performance Using Non-Intrusive EDFM Technology

open access: yesEnergies, 2019
The influence of complex natural fractures on multiple shale-gas well performance with varying well spacing is poorly understood. It is difficult to apply the traditional local grid refinement with structured or unstructured gridding techniques to ...

Study on optimization of well pattern and well spacing for CBM development:Taking Daning Block as an example

open access: yesMeitan kexue jishu, 2023
CBM well pattern optimization design and deployment is a key part of CBM development plan formulation. Reasonable well pattern deployment can not only optimize CBM production, but also reduce CBM development costs and improve economic benefits.

Well Pattern and Well Spacing Optimization of Large Volume Water Injection in a Low-Permeability Reservoir with Pressure Sensitivity

open access: yesGeofluids, 2022
Even with the fractured wells, the primary oil recovery of low-permeability reservoirs is still poor in Block X of Shengli Oilfield. To further enhance the oil recovery, water is injected into the reservoir.

Influence of Well Spacing on Polymer Driving in E Reservoir of Daqing Oilfield

open access: yesApplied Sciences
The E reservoir in Daqing Oilfield exhibits strong heterogeneity, resulting in inconsistent performance of conventional development methods. Polymer flooding is currently implemented using 106 m and 150 m well patterns.
