Overview

The downhole tractor is an electric motor powered tractor system consisting of a surface control panel and downhole tools which include a Tractor Control Cartridge (TCC), a Downhole Tractor Tool (DTT) and auxiliary tools.

The TracSIM software is provided to enable the user to determine in advance the specific tool configurations to control the operation risks. The conveyance process is monitored in real time so that the user knows where the tractor system and the passenger tool are moving. This increases the chances of success while lowering the operation costs.

Application

The downhole tractor is used to convey in highly deviated and horizontal wells:

· Well logging tools

· Perforating tools

· Completion tools
