Gravel Pack Tool (GPT)
The Gravel Pack Tool is used to monitor gravel pack density and any changes that may occur in it during production.
Gravel pack screens act as a filter to prevent sand production in to the wellbore that can lead to reduced hydrocarbon production, damaged screens and completion erosion. The GPT is used to monitor pack material density and also indicate distribution along the gravel pack screen. Comparisons of GPT log data obtained at different times during the life of a production well can highlight variations in the pack density, indicating whether the gravel pack in the producing zones remained unchanged.
