ESimTech is a leading provider of drilling and well control simulation systems. One of their flagship products is the Drilling & Intervention Real-time Interactive Virtual Environment (DRIVE) simulator. DRIVE is a full mission drilling simulator designed to train drilling crews and engineers in safe drilling practices and well control techniques.

What is the DRIVE Simulator?

The DRIVE simulator is a high-fidelity real-time drilling simulator that allows users to train in a virtual environment. It provides a realistic 3D visualization of the rig and wellbore displayed on multiple large-screen displays. The system accurately simulates the drilling process and well control operations using mathematical models of the bottomhole assembly, drillstring, and well geometry. Users can monitor and control real drilling parameters such as pump pressure, flow rates, drill pipe rotation, and hook load from an authentic rig control console.

The simulator experiences various downhole conditions and events such as formation pressures, influxes, losses, and well control scenarios. This allows users to practice recognizing and reacting to operational upsets without safety or economic risks. Critical well control techniques like kick circulation, drillpipe circulation, and well kill procedures can be realistically simulated. The system objectively evaluates trainee performance and provides debriefing and assessment tools for instructors.

The DRIVE simulator offers a safe, realistic, and repeatable environment for drilling crews to gain experience handling well control situations and non-routine events. It is an extremely effective training tool that improves human and organizational response in emergency well control scenarios.

How does the DRIVE Simulator Work?

At the core of the DRIVE simulator is a mathematical well modeling software that dynamically simulates downhole conditions in real-time. It takes into account the physical properties of the borehole, drillstring, drilling fluid, and formation being drilled. As trainees operate the control console, their commands are input into the simulation software which then calculates the resulting downhole response.

Sophisticated subsurface and drilling mechanics models compute pressure and flow dynamics to realistically emulate the drilling process. Formation pressures, fluid properties, drill bit hydraulics, surge and swab pressures are all accurately simulated. The software also implements programmed surface and downhole events like influxes, losses, and well control scenarios.

On the surface end, the DRIVE simulator features an authentic drilling rig control console and virtual displays that provide an immersive training environment. Multiple large-screen projections surrounded the rig console, visually recreating the rig floor and various downhole views. Trainees can thus monitor drilling parameters, pump pressures, flow rates and make real-time control adjustments from the console.

The simulation computers render 3D graphics of the rig displays in real-time synchronously with the downhole calculations. This creates a completely interactive and realistic experience of drilling operations for trainees. At the same time, the simulator objectively records and evaluates their performance for structured debriefing later.

Benefits of DRIVE Simulator Training

Some of the key benefits that the DRIVE simulator provides for drilling and well control training include:

- Safety - It allows crews to train extensively on emergency well control procedures without risks to personnel or equipment.

We are excited to announce that Drawell Analytical will be showcasing our latest advancements in laboratory equipment at the upcoming Shenzhen Exhibition. Among our top-tier products is the biosafety cabinet, an essential tool for laboratories working with potentially hazardous pathogens. Our laminar flow cabinet features an enclosed, ventilated workspace designed to ensure maximum safety for both researchers and the environment. Equipped with safety laminated glass, electrical sockets, and valves, it is engineered to meet the stringent requirements of any laboratory setting.

 

The microprocessor system with an LCD digital display makes operating and monitoring the cabinet air velocity seamless and efficient. Contaminated air is meticulously managed through HEPA filters and a robust blower system. Dirty room air is drawn into the front of the cabinet, where it mixes with contaminated air from within. This contaminated air is then pushed below the work surface, moving through the plenum located on the back side and rising up to the blower, ensuring a clean and safe working environment.

 

One of the key features of our biosafety cabinet is the efficient HEPA filtration system. Contaminated air is pushed through these filters by the cabinet's blower motor, with 30% of the filtered air recirculating into the room or being removed by canopy exhaust, and 70% entering the cabinet from above. This air flows down onto the work surfaces under unidirectional flow, which is crucial for preventing cross-contamination between samples. The laminar flow ensures that the air supply inside the chamber is evenly distributed around the work surface.

 

The air supply inside the chamber also provides an essential protective air curtain on the front space of the biosafety cabinet, which not only protects the samples but also ensures the safety of the researcher. This comprehensive protection mechanism supports three critical aspects: researcher safety, sample integrity, and environmental safety. For more details on our advanced biosafety cabinets, visit our product page.
