Non-man-entry cleaning
Robots and mechanized systems do the work inside tanks, lagoons and pits. Your people stay outside.
Robotic recovery and management of oil and gas sludge
Extracting worth from waste
We clean tanks and lagoons with robots, so no one has to go inside, and recover 90–95% of the oil in the sludge we remove.
- No human entry into tanks or lagoons
- 90–95% of oil in sludge recovered
- 10,00,000 KL of sludge processed
- Founded in 2013 by petroleum engineers from IIT (ISM) Dhanbad
- Patented Sludge Treat and Slop Treat chemicals
- Indian patent for our heating coil system, 2026

Trusted by oil, gas and metals majors
Two jobs, one team of petroleum engineers
Founded in 2013 by petroleum engineers from IIT (ISM) Dhanbad, we take hazardous waste out of your assets safely, then turn it back into product.
Oil recovery from sludge
Oily sludge, slop and tar are separated into oil, water and solids. The oil goes back to you.
Built for the places people shouldn't enter
Crude and product storage tanks
Robots enter through the manhole and clean the floor and sludge mounds while operators control them from outside. Recovered oil goes back into the process.
- Crude oil tanks
- Product and slop tanks
- Tank bottom sludge
- Hazardous waste tanks

How sludge becomes oil again
Our mobile processing line runs on your site and handles about 8–30 m³ per hour. A standard storage tank is usually processed in under a week.

Questions we're asked most
More answers are on each service page and in our full FAQ.
Do your people ever need to enter the tank?
No. Our robotic systems are operated remotely from a safe zone, so no one enters the confined space.
How much oil can be recovered?
We routinely recover 90–95% of hydrocarbons from processed sludge. That offsets disposal costs, frees tank capacity and generates revenue.
How long does robotic tank cleaning take?
Typically 3–7 days, compared with 10–14 days for manual cleaning. Robots can work around the clock.
How much does robotic tank cleaning cost?
It depends on tank size and sludge volume. Robotic methods typically save 40–60% compared with manual cleaning by reducing downtime, waste and labour. Robot-as-a-Service (RaaS) plans are available with no upfront cost.
Can it be done on-site?
Yes. Our modular, mobile setups, including tricanter centrifuges and steam-based LSPU units, are deployed on-site, which removes transport costs.

Arham Oil Secures Indian Patent for Innovative Heating Coil System
A proud milestone in our journey of innovation.
Lagoon Desludging: Restoring Capacity and Recovering Value in Oil & Gas Operations
Industrial lagoons collect wastewater, oily residues, process waste and sludge from refinery operations.
How ATEX Zone 0 Robots Are Changing Hazardous Tank Cleaning
Crude, fuel, slop and process tanks all build up residue that has to be removed safely.
Our mission
Our mission is to introduce eco-friendly technology that quickly and economically breaks sludge back into oil, water and sediments, most of which can be recycled. It is time to stop the spread of lagoons.
