Paper presented at the 2001 SEG Annual Meeting, September 9–14, 2001
Paper Number: SEG-2001-0448
... source VSPs in vertical wells has been of limited value due mainly to the very low amplitudes of shear arrivals on the horizontal components and the limited dynamic range and vector fidelity of the downhole receivers. With high fidelity 3- component sensors, shear body wave transmission and reflection...

Paper presented at the International Petroleum Technology Conference, November 15–17, 2011
Paper Number: IPTC-15215-MS
... Abstract Wells equipped with optic fiber Distributed Temperature Sensors (DTS) provide real-time downhole flow rate information offering an opportunity for effective production management in real-time. The downhole information can also be used to update the reservoir model, leading to a better...

...). The current figure which companies should aim to achieve without the failure of any one of the tool's sensors is 250 downhole circulating hours. 3.0 SURVEY ACCURACY 3.1 Introduction The requirement for improved survey accuracy during drilling has long been an industry aim. In achieving this, the following two...

.... In the pressure build-up test, the well is shut-in, either at the wellhead or with a valve downhole. The curve of pressure vs. time (or flow rate) for a pressure drawdown test followed by a shut-in test is of vital interest for the reservoir engineer. Downhole shut-in tests have proved to give more precise...
