Over 100 Confomance Fracturing Operations in Brazil - Results and Improvements (SPE-113624)

摘要

Many of the mature oil fields in the world produce commingled water. Water production increases the lift cost of a barrel of oil, as it needs surface handling when to be disposed, re-injected into other wells, or used for a different purpose. Several techniques and chemistries have evolved over the past decades to address reduction of unwanted produced water. These different approaches to minimize water production are grouped under the name of water conformance. Selecting the proper water conformance method for a well depends on the correct understanding of the reservoir. Economics remains the main decision driver as to which technique and chemistry to use.
