Novel Concept to Improve Water Flood
Wellsite Geochemistry for Production Optimization

Yongchun Tang, Ph. D

To improve water flood, we work closely with many industrial partners to develop novel polymer called surface active polymer (SAP) to improve oil production for mature oil field. This is a unique SAP product that contains within its composition the chemistry for both viscosity and lowering interfacial tension. These SAP polymer products open a whole new range of possible EOR applications. The unique features of SAP polymer provide (1) lowering water and oil interfacial tension (IFT), (2) shear thickening to provide in-depth of conformance control, (3) designed delayed viscosity to optimize significantly oil recovery. Our preliminary results show the SAP flood can significantly improve the water flood efficiency under low crude oil price.

Enabling the wellsite laboratory that has comparable analytical capability to stationary lab has long been motivated and demanded, as it would provide rapid, dynamic and first-hand information of the target well. In the recently years, we have made major progress by implementing advanced and unique technology to our wellsite lab. These include the wellsite C1-C3 isotope logging, the enhanced Raman for maturity calibration, and the modified pyrolysis for better capture of light HCs. By integrating information from the wellsite analysis, we bring new domain of analytical power and insights to the unconventional resources development. Specific application include (1) relative permeability prediction, (2) sweet spot prediction for horizontal wells, and (3) EUR or production decline prediction.


Dr. Tang has more than 28 years of combined experience in both academic (California Institute of Technology) and industrial (Chevron) institutions. From 1988 to 1999, Dr Tang was a team leader of molecular modeling for Chevron where he pioneered molecular modeling technology for both upstream and downstream applications. He is the first to use modeling tools for oil field chemicals, such as scale control, corrosion inhibition, gas hydrate control and surfactants for enhanced oil recovery. After 11 years with Chevron, Dr. Tang moved to California Institute of Technology as director for Caltech's PEER Center. At Caltech, he was PI and Co-PI for many challenging research projects funded by the DOE, NSF, and many large petroleum industries including Chevron, Shell, Exxon, BP, Conocophillips, Saudi Aramco, ENI-Agip, Total, Devon, PetroChina, and China Petroleum Corporation (Taiwan).

In 2009, Power Environmental Energy Research Institute (PEERI) become an independent research institute for both energy and environmental challenges. Dr. Tang is a frequently invited speaker for many international conferences. He has published over 130 papers in the area of molecular modeling, oil field chemistry, geochemistry and chemical engineering sciences. Dr. Tang is also frequently invited to speak by major oil and service company senior executives, such as CEO of Schlumberger for exploration executive and CEO of Shell for Shell internal EOR workshops.

Dr. Tang is also founder for ChemEOR corporation (improve water flood and enhance oil recovery), Paladin Geological Service (wellsite geochemistry, wellsite treatment, and mud logging), ChemWa (oil field waste water treatment) and Tensiogreen (bio EOR).
