Near El Morro in Casanare, Colombia
Historically, extremely low relative permeability and fluid buildup at the wellhead (condensate banking) have been the primary contributors to restricted production of many wells near El Morro in Casanare, Colombia. While hydraulic fracturing is acknowledged as effectively addressing these and other issues, high in-country costs prompted an operator to identify advanced technologies to enhance well performance and reduce costs, with proppant selection a central focus. In an area where wells are drilled to 16,000 ft TVD (19,000 ft MD), high closure stresses put a premium on exceptionally conductive proppant, and one that likewise can deliver transport capacity and not erode pumping and related equipment.
After evaluating multiple proppant types and sizes in lab tests and modeling encapsulated in a specialized workflow, the operator identified the KRYPTOSPHERE® LD ultra-conductive, low-density ceramic proppant as the top candidate for optimizing well performance in two previously completed wells. Along with appreciably higher baseline conductivity than standard intermediate and low-density ceramic proppant, the smooth and uniform shape of KRYPTOSPHERE LD was seen as a viable option for increasing production within specified intervals that were being recompleted.
