LINK-WellOpt

What is LINK-WellOpt?

LINK-WellOpt is a new Petrel Plug-in to help user to optimize well place- ment in maximizing recovery based on reservoir models without running expensive flow simulation, yet producing highly correlated models.

LINK-WellOpt provides a rapid solution to the challenge in deciding the field development strategy in optimizing well locations under geologic un- certainty. It provides a bridge between geologic and simulation models.

LINK-WellOpt is capable of handling computation in structurally complex reservoir with faulted corner point geometric model, heterogeneous media, and completely general well architecture. The power of LINK-WellOpt lies in its ability to handle high resolution geologic models rapidly without the need for upscaling and the associated loss of reservoir heterogeneity

LINK-WellOpt uses geological model (fine or coarse scale) available as Petrel project. LINK-WellOpt helps Reservoir Modeler (geologist and engi- neer) in understanding the dy- namic impact of the model, toward cumulative recovery. LINK-WellOpt provides qualita- tive (e.g., visualization) as well as quantitative output (numerical table and plots)

How does the Optimization Workflow look like?

Once user has generated reservoir model(s) and possible well combinations, program calculates the diffusive time of flight using Fast Marching Method (FMM). This map is used by the program to calculate the drainage volume considering the ac- tual well schedule. At this step, user may perform evaluation of drainage volume by visualizing the 3D view of drainage vol- ume as well as the quantitative report within each well’s drainage volume. The results of drainage volume calculation will be used by the program to calculate the estimated flow rate and cumulative recovery at each well using semi-analytical approxi- mation of pressure and transient rate. The relative recovery and their ranking for each well/model combination will be report- ed to the user as the final results.
