During the OSRL 2025 event, WellCTRL Engineering executives Matin Ansari (CTO) and Amir Paknejad (CEO) presented a development that is capturing the attention of the offshore sector: PARSim, a three-dimensional simulation software for hydrocarbon release events.
The solution was explained as a predictive model that allows visualizing, in real time, how fluids released from an offshore well behave, both underwater, at the surface and in the atmosphere. The tool has been described as a significant breakthrough for planners, operators and regulatory authorities.
PARSim (Plume & Atmospheric Release Simulator) is a software package that integrates three essential components into a single platform: subsea plume simulation, sea surface trajectories and atmospheric release. Unlike other fragmented models, this system allows the analysis of the complete path of the released compounds, from the reservoir to their possible release into the air.
This level of integration makes PARSim a unique tool of its kind, and there is currently no other commercial system that combines all these elements with such precision.
The tool works on real well data: pressure, temperature, fluid composition and environment conditions. These data are fed into the model to accurately simulate the behavior of the fluid in different phases:
During the interview, the managers showed simulations carried out in the Gulf of Mexico, showing how a release evolves over two weeks, influenced by marine eddies and atmospheric patterns.
PARSim is intended for use by any company performing offshore operations: from deepwater drilling to subsea pipeline transportation companies. The software allows:
It also plays an important educational role during simulations and forums, allowing the impact of different scenarios to be clearly visualized.
The PARSim modules are based on engines recognized by regulatory agencies such as NOAA and are supported by developments at Texas A&M. This gives the model a high degree of technical reliability, and it is projected that in the future it could be adopted by governments as an official tool for emergency management.
One of the most relevant aspects of PARSim is its usefulness during an ongoing incident. Thanks to its 3D modeling and component analysis, it allows to define:
This type of information can be critical during capping or relief well drilling operations.
The company, with more than two decades of experience in well control engineering, has identified a gap in current tools for offshore response. PARSim arose as a result of that unmet need.
"Our goal is not only to respond to emergencies, but also to anticipate them with reliable models that provide safety and operational efficiency."
Amir Paknejad explained.
PARSim is not simply software, but a comprehensive platform that redefines the way the industry visualizes, anticipates and responds to subsea releases. Its ability to integrate different scenarios in real time represents a significant breakthrough for offshore risk management.
With your participation in OSRL 2025, WellCTRL Engineering reaffirms its commitment to the development of technical solutions in the service of operational safety in marine environments.
