There is a large variety of sensing devices for the exploration of oil and gas. These sensors must operate in exceedingly challenging environments, such as high temperatures and high pressures. The majority of sensors are based on electronics because

Downhole fluid analysis (DFA ) has enabled the cost-effective measurement in oil wells of a variety of chemical properties of reservoir crude oils. An immediate benefit of DFA is the improvement of the sample quality of the reservoir fluid in the sub

Summary This paper presents a case study of a North Sea appraisal well in which a vertical fluid-composition variation, missed by a conventional pressure-gradient-analysis method, was observed in situ in real time by a new fluid-composition analyzer

Accurate viscosity measurement is difficult even under the best of conditions and the lengthy time required to send and receive results from a lab prohibit basing important decisions on the viscosity of the reservoir fluid. Those challenges increase

All aspects of crude oil production depend on the proper acquisition and analysis of petroleum samples from subsurface formations. The analyses of hydrocarbon samples that are acquired in exploration wells guide the subsequent production strategies a
