The borehole wall stability of depleted reservoirs is a key problem that restricts the deeper potential exploitation old oilfields. Based on these, according to seepage and elastic mechanics theory porous media, combined with laboratory rock experiments, dynamic evaluation model geomechanical parameters reservoir established, this basis, method wellbore new wells in changing laws influencing fa...

Sense of purpose is seen as a catalyst for successful ageing, predicting wide range health outcomes and mortality. However, its role in fostering subjective well-being during old age has received less attention, especially the bidirectional nature this relationship. The present study examined how sense predicts predicted by life stage. Panel data from Health Retirement Study ( N = 8980) were us...
