U.S. Patent (16/558,432) titled, “Systems and Methods for Operating Downhole Inflow Control Valves to Provide Sufficient Pump Intake Pressure” |
The invention uses data science, physics, and an advanced curve fitting correlation to establish the intake pressure to prevent ESP underloads. The system can be further enhanced to provide automatic advisory for operating ESP wells with ICVs in multilaterals. |

U.S. Patent (16/886,715) titled, “Turbine Powered Electrical Submersible Pump System”
|
Design of a compact turbine powered retrievable ESP capable of generating the required electrical power for operating the ESP downhole in order to reduce surface cable related incidents. The invention comprises an electric motor, a submersible pump, a high-voltage battery, a turbine among other components integrated as one compact piece. The ESP is powered by the high voltage battery and the turbine, thus significantly reducing failure rates since external power cable is not required as it is among most of the failure causes

U.S. Patent (17/010,545) titled, “Systems and Methods to Chemically Liven Dead Wells”
|
The invention addresses field challenges of locked up potential wells arising from high gradient material along the production tubing accumulating during low reservoir pressure wells preventing wells from flowing against network pressure. The patent has application for restoring flow in these wells with accumulation of heavy waxy, heavy gradient oil materials by diluting, breaking down, or reducing the fluid’s hydrostatic pressure gradients in the low-pressure reservoirs, so the wells can flow against the trunk line pressure. The chemical injection string further includes thermal filaments positioned adjacent to each injection valve, configured to increase local temperature in the wellbore.

U.S. Patent (17/140,270) titled, “Managing Water Injected Into a Disposal Well” |
The invention ensures the continuous health of a water disposal network in active oil production systems through maintaining adequate disposal capacity into disposal wells. The invention comprises an oil-in-water meter, adaptive recycle valve, adaptive choke valve, and ESD linked to SCADA, alongside a controlling logic with algorithms installed in the ESD logic that reads the online oil-in-water meter input, compares it with a predefined acceptable range to provide an output instruction for keeping open or closing the wellhead surface safety valve as required. The system works to ensure the oil-in-water content is within the acceptable range prior to disposal. Advantages of the invention includes proactive monitoring and controlling contaminants, thus improving field efficiency by guaranteeing water disposal capacity. Implementing the cost effective system would drastically reduce CAPEX associated with drilling additional wells or OPEX from disposal wells’ treatment efficiency to restore disposal wells’ injectivity. |
