Introduction

The Niger Delta is one of Nigeria’s most important oil and gas producing regions, supporting extensive infrastructure for crude oil and natural gas production, gathering, processing, transportation, storage, and export. Oil & Gas Separation Plants are critical facilities where produced fluids are processed to separate crude oil, natural gas, water, and other associated components before further processing, transportation, or storage.

These facilities rely heavily on Operational Technology (OT) systems to monitor and control separation processes, pressure, temperature, flow, liquid levels, gas composition, equipment performance, and emergency response functions. The availability and integrity of these systems are essential for safe production, process stability, equipment protection, environmental compliance, and operational continuity.

Modern Oil & Gas Separation Plants can use Supervisory Control and Data Acquisition (SCADA) systems, Distributed Control Systems (DCS), Programmable Logic Controllers (PLCs), Remote Terminal Units (RTUs), Human Machine Interfaces (HMIs), Safety Instrumented Systems (SIS), Emergency Shutdown Systems (ESD), Fire and Gas Detection Systems (FGS), process control systems, separators, compressors, pumps, control valves, pressure transmitters, temperature transmitters, level instruments, flow meters, gas analyzers, process historians, industrial servers, engineering workstations, network switches, industrial firewalls, remote monitoring platforms, and vendor remote access infrastructure.

These systems continuously monitor and control critical process parameters such as separator pressure, temperature, liquid levels, gas flow, crude oil flow, water levels, equipment status, and alarm conditions. A cyberattack targeting these systems could disrupt production, manipulate process parameters, compromise safety functions, damage equipment, or create environmental and operational consequences.

The convergence of IT and OT networks, remote monitoring, centralized control centers, cloud connectivity, Industrial Internet of Things (IIoT) technologies, contractors, equipment vendors, and third-party maintenance access has expanded the cybersecurity attack surface of separation facilities.

Threats such as ransomware, malware, unauthorized access, compromised credentials, insecure remote connections, vulnerable legacy systems, insider threats, and supply chain attacks can affect process control and production operations.

An OT Security Assessment provides a structured approach to identifying cybersecurity weaknesses across separation plant infrastructure, evaluating existing controls, and prioritizing improvements according to operational, safety, environmental, and business risks.

Cyberintelsys provides specialized OT Security Assessment services for Oil & Gas Separation Plants in the Niger Delta, helping organizations protect critical process control systems, strengthen industrial cybersecurity, and improve the resilience of hydrocarbon processing operations.

Industry Standards and Compliance

Industrial Cybersecurity Standards for Oil & Gas Separation Plants

Cybersecurity programs for separation plants should address industrial automation, process control, functional safety, equipment protection, production continuity, and critical infrastructure security.

Organizations can align their OT security programs with recognized standards and frameworks, including:

• IEC 62443 – Security for Industrial Automation and Control Systems
• NIST Cybersecurity Framework (CSF)
• NIST SP 800-82 – Guide to Industrial Control Systems Security
• ISO/IEC 27001 – Information Security Management Systems
• CIS Critical Security Controls

These frameworks support security practices covering:

• OT asset identification
• Asset criticality classification
• Industrial network segmentation
• Secure remote access
• Identity and access management
• Vulnerability management
• Security monitoring
• Incident response
• Backup and recovery
• Business continuity
• Industrial security governance

A standards-aligned approach helps separation plant operators strengthen cybersecurity while maintaining process safety, production reliability, equipment integrity, and operational resilience.

Importance of OT Security Assessment

Oil & Gas Separation Plants operate complex and highly interconnected process environments where OT systems directly influence separation, pressure control, flow management, liquid level control, compression, pumping, and emergency shutdown functions.

A cyber incident affecting these systems could result in manipulated process parameters, unauthorized equipment commands, loss of process visibility, production disruption, compromised safety systems, equipment damage, or environmental incidents.

Potential OT cybersecurity risks include:

• Unauthorized access or manipulation of process control systems
• Compromise of PLCs, RTUs, SCADA and DCS
• Unauthorized control of pumps, compressors and control valves
• Compromise of SIS, ESD and Fire and Gas Detection Systems
• Weak privileged account and remote access controls
• Legacy, outdated or unpatched OT systems
• Poor IT/OT network segmentation
• Malware and ransomware
• Insider and third-party access risks
• Supply chain vulnerabilities

An OT Security Assessment helps identify these risks before they can significantly affect production continuity, process safety, equipment reliability, environmental protection, or business operations.

Key Benefits

A comprehensive assessment can help organizations achieve:

• Improved visibility into OT assets and vulnerabilities
• Stronger protection of DCS, SCADA, PLC and RTU environments
• Enhanced SIS and ESD security
• Improved network segmentation and remote access controls
• Better security monitoring and incident response readiness
• Reduced operational and cyber risks
• Increased production resilience and protection of personnel and the environment

A risk-based assessment helps operators prioritize remediation according to the criticality of process control, safety, production, communication, and supporting infrastructure.

Our OT Security Assessment Methodology

1. OT Asset Discovery and Criticality Classification

The assessment begins with a comprehensive inventory of OT assets supporting separation plant operations.

The assessment can cover:

• SCADA and DCS
• PLCs, RTUs and HMIs
• SIS, ESD and Fire and Gas Detection Systems
• Separators, compressors, pumps and control valves
• Process instrumentation, gas analyzers and industrial sensors
• Engineering workstations, servers and process historians
• Network switches, industrial firewalls and remote access infrastructure

Assets are classified according to their operational, safety, environmental, and production importance.

2. OT Architecture and Network Security Review

The assessment examines communication pathways between process control systems, field instrumentation, safety systems, production networks, centralized control centers, corporate IT environments, and external service providers.

The review may include:

• OT architecture and IT/OT connectivity
• Network segmentation, security zones and conduits
• Industrial firewall configurations
• SCADA and DCS communication paths
• PLC, SIS and ESD networks
• Process instrumentation networks
• Remote access and vendor connectivity
• Industrial communication protocols and network monitoring
• OT-to-enterprise data flows

The objective is to identify unnecessary exposure and potential attack paths toward critical process control and safety systems.

3. OT Vulnerability Assessment

A controlled vulnerability assessment evaluates cybersecurity weaknesses across separation plant OT assets.

Activities can include:

• Security configuration, firmware and patch management reviews
• User privilege and industrial device assessments
• SCADA, DCS, PLC, RTU and HMI assessments
• SIS, ESD and FGS security assessments
