Abstract
Chevron Thailand presently drills a well in about 4.5 days on average. In addition,
Chevron Thailand
drilled an approximate 41.5% of cumulative depths that Chevron
worldwide d
rilled last year. As the
reservoirs in the gulf of Thailand are small to
marginal, the key driver to make the wells more economical
and profitable is to
complete the wells as many and as quickly as possible, while safety is still number
one
priority. The b
est way to achieve the level of performance is to perform offline
operation as much as
possible such as cementing and picking up drill pipe offline to
save rig times (Offline operation means
performing an operation simultaneously with
other activities on t
he rig floor). Chevron Thailand has been
going to the next step of
a significant improvement in the offline activities by performing open
-
hole
wireline
logging under the rig floor which eliminates times for logging the well and saves
around 10% of
times pe
r well or 11 hrs. Furthermore, under rig floor cased
-
hole
logging and perforation have been
performed to accelerate production of the wells.
This presentation will describe the concept of the offline open
-
hole wireline logging
and engineering
design of the
components that make this new concept an operational
reality. This presentation will also
show the system that enables performing both
online and offline open
-
hole logging, cased
-
hole logging
and perforation. This
complex integration of newly design and m
ethod will lead us to achieve a new
milestone of drilling
performance in the gulf of Thailand.
