TTI offers a “Zero Discharge” disposal solution for the management and disposal of Naturally Occurring Radioactive Material (NORM & TENORM) generated from upstream petroleum operations, in the form of contaminated soil, sludge, water, pipe scale, etc. This unique integrated service includes NORM field surveys & assessments, equipment decontamination & waste segregation, permanent SFI disposal, and HSE controls.
SFI NORM disposal eliminates pollution caused by dumping and surface storage of NORM waste; and eliminates the high costs of NORM treatment and incineration. TTI’s SFI NORM disposal service is fast becoming the disposal solution of choice by regulators worldwide

SFI Operations – NORM Disposal
Terralog Technologies Inc. (TTI) has provided full scale SFI™ services for the safe disposal of NORM waste generated by Saudi Aramco. TTI was the operator of the Aramco NORM disposal facility in KSA. This project is the first large-scale deep well disposal-injection operation in the GCC area for NORM waste disposal.
A dedicated team was established by Saudi Aramco to analyze the levels of NORM generated by the company’s production operations, and to develop a comprehensive NORM management process. Six methods of NORM waste permanent disposal were considered, and SFI was established as the optimum option in terms of economic and risk assessments (Ref: M. Cowie et al., 2012). SFI project field operations started in April 2015 and over 25,000 bbl of NORM contaminated waste material (including fluid, fines and sludge) have been injected in the first phase of the project.
Special emphasis was placed on the design, equipment selection and operating specifications to ensure safe handling of NORM, maintain wellbore integrity, maintain waste containment in the in-situ target interval, reduce operating costs, optimize formation response and maximize formation storage capacity. The following three stages are applied in order to ensure ‘Process Control’:
- Stage 1: Daily Assessment of Operating Data & Operating Issues
- Stage 2: Detailed Engineering Analyses of Formation Response
- Stage 3: Conceptual Model Development of In-situ SFI Mechanisms
Deep well disposal of NORM contaminated waste has proven to be a viable solution for this project; and all NORM waste streams have been safely handled during SFI operations.
