Evaluation of Inter-well Connectivity for Well Spacing Optimization

A consequence of modern development of low-permeability (‘unconventional’) reservoirs using multi-fractured horizontal wells (MFHWs) is inter-well communication. Because inter-well communication can affect well performance for many wells, oil and gas operating companies are interested in the development of easy-to-implement, but effective, reservoir engineering methods for quantifying inter-well connectivity between MFHWs. Current methods for quantifying inter-well connectivity include rate-transient analysis (RTA) and pressure-transient analysis (PTA, well-testing). In this research project, a combination of RTA/PTA approaches will be explored, and a workflow developed, for the efficient evaluation of inter-well connectivity. A workflow that integrates these RTA/PTA approaches for more effective inter-well connectivity analysis will be provided to the industry partner. The benefit of this study to the partner organization is the provision of tools, databases and workflows that can assist with the optimization of field development practices such as well spacing.
