Pre-Abandonment Logging and Well Integrity, 7th Dec 2017

7th December 2017 @ 3:30 pm - 7:00 pm CET

Highlight: Social hour (or longer 🙂 ) starting at 17:30 will be at Le Café Hathor, Maliestraat 22. Which is only 5 min walk from KIVI and it is open bar till we run out of money.

‘The Sound of Silence’ : Innovative Approach to Confirm Barriers Using Spectral Noise logging 

by Gulfiia Ishmukhametova, NAM

Abstract
After initial plug and abandonment activities in one reservoir, measurements showed pressure build up in the annuli. Spectral noise, high precision temperature and production logging were performed to determine the cause of sustained annulus pressure and the location of leaks. The data acquisition was performed both under shut-in and pressure bleed-off conditions and both log responses were compared to identify changes in noise patterns. The noise from specific events such as channeling or reservoir activity was detected, so the abandonment program could remediate these issues successfully.
Application of spectral noise logging in this field yielded evidence that this technology can identify annulus flow for very minor build-up rates (0.1 bar/day). Our work demonstrates the ability to locate the source behind multiple barriers and to validate plug integrity. It was observed that noise responses have a good correlation with ultrasonic cement evaluation logs aiding better understanding of the gas migration mechanism and change in noise patterns.

Biography
Currently Gulfiia is associate Subject Matter Expert for Abandonment Logging at Shell. In her current role she is providing Petrophysical support to Development, WRFM, Exploration in Land Asset and Asset Groningen in NAM. Gulfiia is a petrophysicist with over 10 years of experience in LWD/WL data acquisition, interpretation, petrophysical modeling, structural/ geomechanical analysis with wide operational experience, who spent considerable time in interpretation of complex clay-rich sandstone formations, carbonates, tight gas and unconventional source rocks, as well as complex clastic, carbonate and unconventional fields of Russia, Brasil, USA (Eagleford Shale), Barents Sea, UAE, the Netherlands (Area West, North, Groningen). Prior to joining Shell Gulfiia accumulated vast experience working for major service companies (Schlumberger, Halliburton) which provided her with deep knowledge in processing, interpretation and operations of all types of logging tools, including NMR, FMI, Spectrometry, Acoustic. Gulfiia’s has graduated with Honors as Master of Mathematical Modelling of Processes in Petroleum Refining from Ufa State Petroleum Technology University (Russian Federation).


Employing acoustic impedance properties and flexural wave imaging in annular material characterization

by Kamaljeet Singh – Schlumberger

Abstract
Worldwide, government and regulatory officials are informing the oil & gas industry that unproductive wells must be sealed to permanently remove these potential environmental threats. Services companies are developing tools and methods to limit the economic impact of fulfilling these obligations. A crucial requirement of permanent abandonment procedure is the placement of a cement plug across the wellbore and in the annuli of remaining casing sections in the well once upper sections have been successfully cut and pulled out.
This presentation aims to demonstrate the use of a multi sensor wireline tool to characterize annular material based on acoustic impedance properties and flexural wave imaging. This data is used to confirm annular barrier, support casing cut and pull optimization and evaluate Perforate, Wash & Cement (PWC) P&A technique.

Biography
Kamaljeet Singh has 20 years of Schlumberger Wireline experience in UAE, India, Sudan, Nigeria and the UK including the last 10 years as Well Integrity and Production Logging Domain Champion. He currently works in UK where he was involved in multiple Plug & Abandonment projects in the North Sea.


As usual all have an opportunity to socialise with fellow petrophysical professionals over drinks and snacks.

Doors will open for registration and coffee at 3:30 pm and the talks will commence at 4:00 pm. The social hour will begin at 5:30pm. This time our social hour shall have a extra pleasant twist to it. Stay tuned for updates.

Thanks to the generosity of our sponsors, attendance will again be free. However please RSVP before 6th of December 2017 by sending an email to info@dps-nl.org with your name, position and affiliation.
