The
Quantitative Fluorescence Technique (QFT) is a patented
technique used for a more accurate determination of the amount
of drill cuttings by measuring fluorescence, which uses
a sensitive portable fluorometer to give quantitative
values for the oil content in the cuttings. As long
as representative samples can be obtained, either while
drilling or from cores, QFT is a more direct measurement
of the oil content than can be obtained from wireline
logs. This technique uses a portable fluorometer to
ensure the fluorescence of the crude oil that has been
extracted from drill cuttings. |

Advantages
of QFT
QFT provides direct
measurement of oil concentration, making it an effective,
quantitative tool for formation evaluation and correlation
applications. It has been proven effective in wells
drilled around the world, providing information that
- Accurately quantifies oil zones
- Finds oil missed by other techniques
- Pinpoints drill stem test location(s)
- Identifies source rocks
The technique
can be used at the wellsite while drilling or in the
laboratory after the well has been drilled. It provides
oil concentration data from representative drill cuttings,
sidewall cores or conventional cores, and has been used
effectively.
Solves all the problems
- Reliablly detects the presence of crude oil
from cuttings or cores
- Yields a quantitative oil profile
- Simple, fast, and reliable
- QFT works on all type of crude oil
- QFT works in fresh water zones, where wireline
and MWD do not
- QFT works in highly fractured formation, even in
shale where wireline and MWD are difficult to interpret
- Even in highly laminated shale/sand sequences, QFT
will show where the zones of maximum oil concentration are
