... fully, resulting in low economic benefit. With over a decade of practice, a cost-effective hybrid well pattern adapted to each layer and each region was formed which shows its efficiency in development of Yan’an gas field. In the hybrid well pattern, directional (vertical) well is adopted to fully...

... are investigated. The effects of different well patterns (five-spot and line drive) and well spacing on fraction of CO 2 retained in reservoir and cumulative oil production are also investigated. Furthermore, the effect of different CO 2 injection modes, i.e., continuous CO 2 injection and water-alternating-gas...

... without recognizing or honoring the inherent complexities of sand bodies in terms of competitive units with different hydraulic transmissivities. We present a study highlighting the impact of improper well pattern selections that place injection wells in very high permeability channels. It can result...

The overall procedure, which we refer to as well pattern optimization (WPO), entails a new well pattern description (WPD) incorporated into an underlying optimization method. The WPD encodes potential...
