Who Should Attend
Geologists, engineers, technicians, and petrophysicists who work with open-hole logs in highly deviated wells and need a better understanding of how to use log data acquired in these wells. Ideally, attendees should already have taken a basic well log analysis course.
By the end of the course, participants should be able to do the following:
- Explain the impact of water trapped in low spots in undulating wells on well productivity.
- Explain the differences in toe-up versus toe-down wells on well productivity.
- Compare the differences in geometric versus geosteered well trajectories and explain when each has its advantages.
- Describe the differences in mud filtrate invasion on log measurements in horizontal versus vertical wells.
- Describe the impact of measurement depth-of-investigation on apparent dip of photo electric, density, and resistivity images.
- Recognize when the well bore trajectory is climbing versus falling relative to the bedding from borehole image logs.
- Describe the process to get correct bulk log measurements from image log measurements in horizontal wells.
- Identify the effects of resistivity and acoustic anisotropy on log measurements.
- Know how to use borehole images to orient pressure and sampling tools.
- Contrast the types of cased-hole petrophysical measurements with those acquired open-hole logging-while-drilling and explain the limitations of each.
- Describe the types of information derived from production logging measurements and contrast that with conventional open-hole log measurements.
This course provides an overview of issues involved in acquiring logging measurements in highly deviated wells as well as difficulties involved in interpreting those measurements. Emphasis will be placed on understanding logging while drilling instruments that make azimuthal measurements and understanding special processing required to get accurate bed dips from those measurements as well as to get accurate bulk properties such as bulk density, neutron porosity, total gamma ray count rate, and deep formation resistivity.
Geosteering versus geometric well trajectory placement will be discussed. A description of how new deep-sensing resistivity tools work will be given and examples will be shown illustrating how these tools may help improve well bore placement. Production and interpretation issues with toe-up, toe-down, and undulating horizontal wells will be discussed.
When insufficient open-hole log measurements have been acquired, cased-hole log measurements may sometimes be used to fill the gap. Pulsed neutron capture and pulsed neutron spectroscopy tools will be briefly discussed and the methods used to deploy these tools down-hole will be covered. There will also be a short discussion of array production logging tools to complete the cased-hole logging options.
