The use of horizontal drilling and hydraulic fracturing has been credited for much of the success that has been achieved in ultra-low permeability shale reservoirs, making it possible to produce natural gas, natural gas liquids and crude oil at economic rates. Even though thousands of wells have been drilled and completed using these techniques, there are relatively few modeling tools available to the industry that are designed specifically for these applications leaving much of the optimization process up to trial and error techniques that are costly and time consuming.
This presentation will cover a recent case history where new software tools and workflows were used to more effectively design and predict well performance including the use of shale reservoir characterization, hydraulic fracture simulation and reservoir simulation tools designed specifically for these complex well geometries and difficult reservoir conditions.
The workflow is focused on designing stimulation treatments that maximize the stimulated volume of the reservoir around the wellbore and also maximizes the connected fracture area within this volume. This combination can result in increased production rates while also increasing the possible ultimate recovery that can be achieved from a given wellbore.
This presentation provides information on these new tools, the workflows generated for these new tools and the results of an early application that has yielded impressive results, even when applied in an established shale field within the USA.
