Complex Wells Reservoir Simulation Workflow

Complex wells, such as wells containing long horizontal sections, are becoming more common as the industry meets the challenges of developing increasingly remote and complex reservoirs. These wells often contain a mixture of complex devices such as flow control valves (FCV), inflow control devices (ICD), and pumps to improve well cleanup, delay water or gas breakthrough, and increase sweep efficiency of reservoir fluids. Key challenges include designing single wells to full field scenarios quickly, modeling completions and inflow performance, and capturing subsurface uncertainty. ECLIPSE reservoir simulation software simulates complex well topology with its mature and advanced multisegmented well (MSW) model. Petrel Reservoir Engineering (RE) provides powerful well modeling tools that allow efficient design of complex wells and advanced completion design.

Capabilities 

• Accurately simulates multibranched wells together with their comingling branch flows.
• Correctly describes multiphase flow in the wellbore.
• Represents the wellbore with varying fluid mixture composition along the wellbore resulting from influx from the formation.
• Includes wellbore friction, hydrostatic, and acceleration pressures; handles velocity difference between the phases due to slip.
• Simulates crossflow in the wellbore Full field development scenarios: investigates well spacing, well types (horizontal and vertical), and drainage strategies Single well placement: examines infill wells, length (vertical or lateral placement) for sector and full field modeling.
• Multilateral wells: models fork and fishbone wells; allows you to look at the number, configuration, and length of laterals for sector and full field modeling.
• Completion Design: offers full range of options from openhole to inflow control valves for standard and multilateral wells.
• “Simple” well(s) study: investigates infill wells, well spacing, and placement together with recovery and completion strategy.
• Uncertainty analysis and optimization: allows analysis and optimization of well designs and completions using in-built Petrel workflows and engines.
