Abstract

Objective
A lack of data and models for corrosion, scale, and stress cracking at the extreme temperatures and pressures encountered in ultra-deepwater reservoirs increases the economic and safety risks of offshore production. The objective of this project is to develop the necessary data, models, and experimental tools to assess corrosion, stress cracking, and scale formation at extremes of temperature and pressure encountered in deepwater development.

Project Description
Theoretical and experimental high pressure/high temperature (HPHT) research will be conducted at realistic ultra deepwater temperature, pressure, and salinity conditions to validate parameters for HPHT modeling to assess the risk of scale and corrosion. A methodology to apply vertical scanning interferometer as a tool to inspect severity of corrosion and deposit formation will be developed for field operation.

The key overall deliverable will be a detailed technical manual of recommended decision support guidelines based upon extended SAFT/Pitzer models to predict scale and corrosion formation potential in ultra-deep HPHT wells.

The major impact of this project will be the reduction of uncertainty about scale and corrosion formation in ultra deep HPHT wells and concomitant reduction in cost and potential environmental risk.
