He holds 2 patents that focus on enhancing the efficiency and stability of gas wells. His innovative methods are crucial for the oil and gas industry, particularly in optimizing drilling operations.

Latest Patents

Zheng's latest patents include a method for predicting the on-set of formation solid production in high-rate perforated and open hole gas wells. This method describes the stability of perforation and open-hole cavities by incorporating both rock and fluid mechanics fundamentals. It calculates the pore pressure gradient using the non-Darcy gas flow equation, coupled with the stress-state for a perfectly Mohr-Coulomb material. Sand production is assumed to initiate when the drawdown pressure condition induces tensile stresses across the cavity face. Both spherical and cylindrical models are presented, with the spherical model suitable for cased and perforated applications, while the cylindrical model is used for horizontal open-hole completions.

Another significant patent by Zheng is focused on breakout control to enhance wellbore stability. This method encourages breakout formation during the drilling of hydrocarbon-producing wellbores. By selecting the weight of drilling mud appropriately, breakout control is achieved, and the wellbore path can be directed to facilitate this control. This results in efficient drilling operations and enhanced stability of the wellbore as hydrocarbon fluids are produced from subsurface reservoirs.
