Fluid Identification of Deep Low-Contrast Gas Reservoirs Based on Random Forest Algorithm by CAO Yuan, ZHAO Yuanliang, YUAN Xuehua, YUAN Long, RONG Junqing, ZHAO Pan, BIE Kang

“…However, the degree of carbonate cement development is the main factor of the reservoirs with low contrast in the northern well area. The accuracy of the fluid identification model of low contrast gas reservoir based on random forest algorithm is 89.25%, which weakens the multiple solutions caused by a single fluid identification factor and provides a reliable basis for the efficient development of gas fields.…”

Comprehensive Evaluation Method for Complex Fluid in Low Porosity and Low Permeability Reservoirs by ZHENG Yang, LU Yunlong, SHI Xinlei, ZHU Meng

“…Comparing and analyzing the logging and logging data of oil, gas, and water layers confirmed by testing, pressure measurement, and sampling, it is believed that the intersection amplitude of volume compression coefficient and Poisson’s ratio, apparent formation water resistance, gas logging anomaly multiple, and pyrolysis gas chromatography are more sensitive to the response of fluid properties. Based on the four types of parameters mentioned above, a fluid discrimination model for oil, gas, and water layers is established using support vector machine algorithm, with 70 samples of oil, gas, and water layers confirmed through testing, pressure measurement, and sampling as data samples, including 51 samples as training samples and 19 samples as testing samples. …”
