Methods are provided herein for an end-of-life recovery of mobilized hydrocarbons from a stranded hydrocarbon pay zone within a subterranean reservoir by way of a recovery well. In some embodiments, the stranded pay zone is located between mobilized hydrocarbon zones of thermal recovery operations. In some embodiments, the stranded pay zone is an upper stranded pay zone located above a mobilized hydrocarbon zone of a thermal recovery operation. In some embodiments, the stranded pay zone is a lower stranded pay zone located below a mobilized hydrocarbon zone of a thermal recovery operation. The methods herein involve commencing end-of-life recovery at an end-of-life stage after a production threshold is achieved for thermal recovery operations.

Systems and methods include a computer-implemented method for performing well placement and configuration. Two-dimensional (2D) target entry (TE) points are generated in an area of interest (AOI) for wells to be drilled in an oil reservoir, where the 2D TE points are positioned according to a defined well length resolution. A single lateral is designed for each well using the 2D TE points, where each single lateral is designed with a different length, completion zone, azimuth, and orientation. Using the single laterals, a dynamic reservoir simulation is executed for the wells to be drilled in the oil reservoir, including rotating between different three-dimensional (3D) configurations for each 2D TE. A 3D configuration for each 2D TE is selected for each lateral and based on executing the dynamic reservoir simulation.

The invention presents a methodology for evaluating the drainage efficiency of the proposed drainage mesh, by identifying poorly drained regions for mesh optimization and/or implementation of complementary projects, in addition to qualitatively evaluating the drainage effect of a field with different number of wells and units and, finally, comparatively evaluating the drainage quality from different reservoirs, thus observing opportunities for optimizing production management, such as activating different intelligent completion valves, for example. To achieve this objective, it applies a set of filters to the mobile HPHISO map in order to identify the regions that have the greatest potential to be explored and that will bring greater recovery gains for a given oil field.

A method for coupling hydraulic fracture network extension and production performance of a horizontal well in an unconventional oil and gas reservoir includes: establishing a complex hydraulic fracture network model of a fractured horizontal well in an unconventional oil and gas reservoir based on a fracture extension theory; constructing three-dimensional three-phase mathematical models of seepage for the fractured horizontal well based on an embedded discrete fracture model; and constructing a fully implicit numerical calculation model by a finite difference method through three-dimensional orthogonal grids, and solving iteratively, thereby accurately predicting a production performance characteristic of the fractured horizontal well in the unconventional oil and gas reservoir. The method combines a fracture extension model with a production performance prediction model to realize the coupled simulation and prediction of the hydraulic fracture network extension and production performance of the horizontal well in the unconventional oil and gas reservoir.
