Abstract

Quantification of pressure interference among wells in a well system is determined by determining a base productivity index for a target well in the well system. The base productivity index is free of interference on production through the target well from flow through other wells in the multiple wells. A current productivity index for the target well is determined. The current productivity index is affected by interference on production through the target well from flow through other wells in the multiple wells. An interference modulus is determined for the target well based on the current productivity index and the base productivity index for the target well. Using the interference modulus for the target well, an effect, such as a numerical value representing the effect, on the target well, of the simultaneous flow through the other wells in the multiple wells is determined.

Abstract

The laterals of a smart multilateral completion are divided into a number of compartments for improved monitoring and controlling of unwanted fluid production. The productivity index (PI) of each compartment is determined by conducting downhole tests utilizing the downhole liquid metering, real-time pressure measurements, and the electrical inflow control valve (ICV). The PIs and other testing results are used to calibrate a multiphase single well simulation model to select the optimum ICV opening setting at each compartment. The calibrated simulation model is used in a fluid dynamic simulator (e.g., PIPESIM) to generate simulation results based on different ICV opening settings. The optimum ICV opening setting is selected based on the simulated well production delivering the target oil rate while satisfying the constraints of (i) the maximum allowable liquid production rate from each compartment and (ii) the maximum allowable reservoir pressure drawdown all the compartments combined.

Abstract

Methods for seismic imaging of a subterranean geological formation include receiving first acoustic impedance data, having a first resolution, associated with wells in a subsurface region. A system receives seismic data including second acoustic impedance data having a second resolution. The system performs a quality control process configured to identify a mismatch between the first acoustic impedance data and the second acoustic impedance data. The system resamples the second acoustic impedance data into a three-dimensional (3D) grid model. The system scales up the first acoustic impedance data into the 3D grid model. The system downscales the second acoustic impedance data controlled by the first acoustic impedance data in the 3D grid model. The system generates third acoustic impedance data representing fine-scale impedance data. The system extrapolates the fine-scale impedance into areas or regions having no seismic data coverage or poor seismic data coverage.

Solidified nitrogen is placed at a downhole location within a wellbore formed in a subterranean formation. The solidified nitrogen is encapsulated by an emulsifying agent. The emulsifying agent is configured to dissolve in response to exposure to a downhole fluid. The solidified nitrogen encapsulated by the emulsifying agent is exposed to the downhole fluid at the downhole location within the wellbore, thereby dissolving the emulsifying agent and releasing the solidified nitrogen. The solidified nitrogen is allowed to sublimate into nitrogen gas within the wellbore, thereby reducing hydrostatic column in the wellbore. The downhole fluid is produced from the wellbore to a surface location.
