VERSA-OUT System with PEN-8 Package Enables Removal of VERSAPRO System Filtercake in Less than 24 Hours

Published: 06/07/2018

Concrete blue texture

The well successfully produced during well test operations, eliminating the need for coiled tubing contingency operations. The well cleaned up in less than 24 hours, rather than the anticipated 48 hours, and well test data indicated low skin.

The PEN-8 package successfully dispersed the filtercake left by the VERSAPRO system. The filtercake before dispersal is shown on the left; the filtercake after dispersal is on the right.

Background
In the Gulf of Mexico, an operator planned to use a 1.52-sg VERSAPRO* invert-emulsion reservoir drill-in fluid system to lay down a nondamaging filtercake in an openhole well. A ClearPAC* polymer-free viscoelastic surfactant gravel-pack fluid would be used to gravel pack the interval. A 1.56-sg VERSA-OUT* system was formulated with the PEN-8* advanced breaker surfactant package to break down the ClearPAC fluid and disperse the VERSAPRO* invert-emulsion reservoir drill-in fluid system filtercake for optimal production after the gravel pack to avoid the added time and cost of a coiled tubing operation.
Products Used
VERSAPRO
Invert-emulsion reservoir drill-in fluid system

Minimize formation damage problems in high-temperature, low-permeability, openhole-completed reservoirs.
VERSA-OUT
Water-based filtercake breaker system

Delay invert-emulsion filtercake destruction, allowing placement during the completion to maximize contact and efficiency.
ClearPAC
Polymer-free viscoelastic surfactant gravel-pack fluids

Reduce formation damage and enhance gravel-packing efficiency with polymer-free fluids.
