Уважаемые коллеги!
13 февраля 2020 г. (четверг) в 16:30 в главном конференц-зале ИГМ/ИНГГ состоится аспирантский семинар:
BEHIND CASING/TUBING OPPORTUNITIES IDENTIFIED FROM CASED HOLE WATER SATURATION MEASUREMENTS
Докладчик: Long Jiang, Schlumberger
Abstract: Cased hole water saturation conditions are more complicated versus open hole as the sensors measure through the casing/tubing and cement thicknesses. Traditionally the pulsed neutron tools were used to provide the formation sigma (∑) and carbon/oxygen (C/O) ratios. The cased hole formation resistivity (CHFR) was introduced in year 2000. The latest technology, known as new generation pulsed neutron tool was made available in 2017. The principles and applications of all methods are discussed including regional case studies demonstrating the benefits and impact to the field development. Saturation determination practical steps are also presented for in tubing completions.
More activities are being carried out in cased hole operations, due to the low oil price outlook. The goal is to produce more hydrocarbon from the mature fields at lower costs. These practices prove good timing to discuss and review the traditional versus the new technology used in cased hole water saturation measurements.
The applications include evaluation of bypassed pay, alternative to lack of open hole data due to difficult well conditions, reservoir monitoring with time-lapse analysis, risk and cost minimization through planned cased hole logging providing important benefits to the petroleum industry.
Biography: Long Jiang joined Schlumberger as a field engineer in November 1984. He has worked in many areas including Asia, the Middle East, the North Sea, and Canada. In 2000 he was assigned as senior petrophysicist in Calgary,Canada. He moved to Bangkok,Thailand in 2004 as senior petrophysicist for the region of Thailand, Myanmar, and Vietnam. Long has been principal petrophysicist in Kuala Lumpur, Malaysia since October 2007.He worked various projects in South Asia, South East Asia, China and Europe. He is an author of SPE and SPWLA papers as well as a member of both societies.
