Coiled tubing memory intervention data tool

CT MIND provides key insights from downhole data to improve job and tool efficiency

Overview

The battery-operated coiled tubing (CT) memory intervention data (MIND) tool records high-frequency data downhole without a cable. It provides data for insights into job and tool performance to improve operational strategy and efficiency.

Applications

CT milling
CT cleanout
Full range of CT services, except for CT drilling

Benefits

Job performance

Provides key downhole data from harsh environments to improve job performance

Tool performance

Uses bottomhole assembly (BHA) data to characterize tool performance

Easy-to-use solution

Integrates with no change required in the job design

Efficient assembly

Requires only minimal rig-up or rig-down efforts

No moving parts

Comprises only fixed parts

Toolstring attachment

Deploys without the need for a cable

Features

Battery operated
Designed to measure multiple parameters
Rated for high-shock and high-vibration environments

How It Works

Customized settings record targeted data

A stand-alone computer utility configures the CT MIND tool after the installation of batteries. The tool connects to the toolstring, operates independently, and stores the desired data in memory during the operation. Various triggers (e.g., time-based, value‑based) can initiate recording at specific times during an operation. When the CT MIND tool returns to surface, the user connects a special cable to download the recorded downhole data.

Wide range of sensors captures vital data

The CT MIND tool measures

axial load
torque
annular pressure
annular temperature
accelerations (three axes).
