Well test. Design & analysis / Испытание скважины. Проектирование и анализ

Well test analysis is one of the cornerstones of reservoir analysis, as it is only through the wells that we ever have the opportunity to make direct contact with the reservoir. Nonetheless, the reservoir parameters of importance to us are not measurable directly, hence the need to make an indirect interpretation of pressure and flow rate transients in the process we call well test analysis. The need to solve the inverse problems inherent in well test analysis makes the field one of the most intricate mathematically, while still dependent intimately on the practical characteristics and accuracy of the pressure measurements themselves.

There are few in our field who accomplish the bridge between mathematical analysis and engineering practicality as proficiently as George Stewart. He has worked centrally in the field of well testing and well test analysis for much of his professional career, starting in the 1970s when he was one of the founding faculty members at the very successful Department of Petroleum Engineering at Heriot Watt University in Scotland. In addition to advising decades of student research projects in well test analysis, George has been a key figure in the development of well testing in an industrial context. He was the principal architect of one of the earliest and most successful commercial well test analysis software packages, as well as a leading participant in the development of the wireline formation tester class of downhole tools. Additionally, by extensive active involvement in real reservoir development projects, George has accumulated a vast personal encyclopedia of practical reservoir experience, which he is able to recall in great detail. Whatever proposition may be discussed in a professional meeting, George has an example that supports (or refutes) it. <...>
