Cloud Computing Optimizes Vaca Muerta Well Spacing, Stimulation Design

This paper presents a numerical simulation work flow, with emphasis on hydraulic fracture simulation, that optimizes well spacing and completion design simultaneously.

Well spacing and stimulation design are high-impact design variables that can dictate the economics of an unconventional development. The objective of the complete paper is to showcase a numerical simulation work flow with emphasis on a hydraulic fracture simulation methodology that optimizes well spacing and completion design simultaneously. The work flow is deployed using cloud computing functionality.

Objective

The Vaca Muerta shale has grown in drilling activity and overall production significantly over the past decade. The mode of development started from vertical wells with multistage hydraulic fractures, with a transition to horizontal wells in the early 2010s.
