Title:  Multi-Basin Case Study:  Remediating Damage from Fracture Driven Interactions Utilizing a Rigless Chemical Process and a Bit More

Abstract:

The development of US unconventional wells has reached the point where most new completions risk interactions with existing parent wells.  Fracture driven interactions between child and parent wells result in a wide variation of production impacts but in many cases, production can be negatively affected and cannot be solely attributed to stolen reserves from the child well.  Numerous damage mechanisms are identified with the two most dominant mechanisms being capillary phase trapping and fracture conductivity damage from FR-iron gels. 

Multiple surfactant-nanoparticles chemistry was studied to reduce capillary pressure across multiple unconventional basins.  A new chemistry was developed that significantly reduced the required amount of citric acid to remediate FR-iron gel damage.  The chemistry was integrated into a novel rigless process that utilizes a diversion process combined with a specific volumetric design methodology to improve fluid distribution along lateral and into the propped fracture network and fracture-matrix interface.  Case studies across two different basins are described, yielding 2-10x increases in hydrocarbon production and paybacks in less than 4 months.

This process is being commercially scaled and is being trialed on frac hit wells in other basins.  This technique allows the industry to reassess damage from frac hits and potentially recover reserves that were previously thought unrecoverable. 

This process is being applied to wells that are underperforming as a restimulation technique and a case study from the DJ Basin and Anadarko Basin will be reviewed.
