Profile

Complex Flow Design is a provider of consultancy services for the energy industry. The company provides contract research and development services within numerical simulations and analysis.
Multi-phase flow numerical simulation software
Complex Flow Design develops state-of-the-art methods and software tools for making realistic numerical simulations of multi-phase flow in process, hydraulic and sedimentation engineering. The framework for these numerical simulations is based on the general-purpose computational fluid dynamics (CFD) software suite FLOW-3D®, developed by Flow Science USA. Complex Flow Design is an associate partner of Flow Science in Norway.
Multi-phase flows are common complex flow processes found in offshore oil and gas exploration and production processes. Understanding and managing multi-phase flows in deep sea processing systems or harsh arctic environments is becoming more important as the oil and gas industry strives to understand and minimise risks.
Realistic numerical solutions for complex flow processes result in more insight and better decisions.
Deterministic process modelling of deep-water petroleum reservoirs
Sedimentary successions of ancient sediment-gravity flow deposits are important reservoir rock hosting hydrocarbon resources in many parts of the world, which makes submarine mass flow processes of great interest to the petroleum industry. Reliable numerical modelling of sediment gravity flows and their deposits is needed.
MassFLOW-3D:

Builds the stratigraphic anatomy of sediment-gravity flow deposits
Identifies preservation and distribution of permeability barriers
Models complex reservoir heterogeneities
Performs sensitivity and risk analysis

MASSFLOW-3D analysis:

Tests play concepts and reduces uncertainty of geological models
Improves the understanding of mass flow processes
Simulates transport and spatial distribution of sediments
Visualises the evaluation of the whole depositional system
Provides a cost-effective solution

3D multi-phase flow analysis of offshore separation and mixing vessels
Complex Flow Design provides 3D multi-phase flow analysis of offshore separation and mixing vessels.
Offshore numerical simulation and analysis tool
The CFD-based simulator Separation offshore Survey (SoS) is the basis for these specialised studies. SoS is a numerical simulation and analysis tool to provide enhanced focus and understanding on multi-phase flow and separation efficiency in gravity separators.
SoS services for gravity separators offshore include:

Analysis for design or redesign of separators at fixed and floating production systems according to NORSOK standard P-100 for separator design
Detailed modelling and simulation of fluid-flow distribution and separation behaviour
Verification of the efficiency of separators to avoid short-circuiting, mixing and stagnant spaces

The performance of gravity separators can be improved with CFD modelling, as it can:

Develop vessel inlet configurations to improve uniformity of gas and liquid flows
Determine the influence of internal equipment on hydraulic efficiency and separation performance
Gauge the effects of changes in operating conditions
Accurately model small-scale phenomena (multi-phase flows, drops, particles, bubbles)

CFD-based modelling and simulation of mud mixing for drilling fluids
Complex Flow Design offers CFD-based modelling and simulation of mud mixing for drilling fluids. In addition to preventing the settling of particles and distributing the flow as evenly as possible throughout the vessel, an optimised mixing tank will provide:

Optimised impeller size and placing
Well-defined circulation with minimum losses in the vessel
Optimal blending time
