As exploration companies drill deeper wells, the information and data processing need increases and the well bottom temperatures continue to rise. Multilateral wells need to monitor the pressure, temperature and multiphase flow in each lateral to optimize the production of the reservoir. This push requires permanently installed gauges and data acquisition systems that can last for up to 10 years in harsh high temperature environments. These temperatures and lifetimes are far beyond the capabilities of conventional silicon integrated circuits but recent developments at Honeywell have identified a solution to this problem.
HTMOS® products are being used in a number of downhole applications including permanent monitoring, intelligent completions, measurement while drilling (MWD) control and data acquisition systems. Standard products, memories and gate arrays enable a greater processing capability for advanced systems.
Honeywell’s ability to engineer vibration and shock-resistant high temperature multi-chip modules (MCM) enables the longer and narrower package requirement for ever-narrower instrument packages. Where the cost of electronic component field failure is often in the millions of dollars, our HTMOS products and MCM packaging provides an immediate, substantial improvement in subsystem reliability at a fraction of the cost of drilling rig downtime. Honeywell’s extensive reliability program has demonstrated components that can survive five years of continuous operation at 225°C.
