摘要： A system and method for developing a wellbore is disclosed. A sample is obtained from the wellbore during a drilling operation. A first test device tests the sample to obtain a first measurement of a parameter of the sample. The first measurement of the parameter is input to a second test of the sample performed at a second test device to obtain a second measurement of the parameter. A parameter of the developing operation is altered based on the second measurement of the parameter.
