reach drilling article. Complex well geometries in
the West Sak field development on Alaska’s North Slope are approaching
the limits of ERD technology. Authors from ConocoPhilips, ASRC
Energy Services E&P Technology and Halliburton describe
the mechanical and procedural ways to solve weight-transfer
drilling challenges in this remote, environmentally sensitive
drillpipe for HPHT. What do you do when you are drilling
in a deep, hot, mean drilling environment and the fluid drops
away? How do you communicate with your MWD tools and control
the well? Authors from GrantPrideco and Sperry-Sun explain
how it was done on a Central American well using IntelliServ
control in soft sediment. This article presents a
case study of the use of a large 26-in. ID, rotary steerable
system. The reservoir to be accessed stepped out 1.4 mi at
a depth of less than 9,000 ft below mudline. To intercept this
reservoir, at an inclination that conformed to the drilling
design, required deviation from vertical within 300 ft of the
mudline. Authors from Schlumberger and BP tell the story.
an LWD “look ahead” and “see around” logging
tool to guide horizontal drilling within a few feet of a formation
interface. The reservoir was water driven and did not have a
gas cap, so the challenge was to get as close as possible to
the top of the reservoir without leaving it. This sort of precise
placement allowed more reserves to be accessed and developed.
Authors from Schlumberger and Chevron Nigeria describe how it
was done. .
study in ExxonMobil-operated Means oil field, in the Permian
basin, West Texas, has established porosity-permeability relationships
for the Permian Queen, Grayburg and San Andres formations.
The optimized workflow used borehole image and conventional
log processing with calibration to core data. This approach
allowed Schlumberger to quantify porosity and permeability
heterogeneity in vuggy carbonate facies in the field. Petrophysical
rock types have been differentiated using image and conventional
log data and neural network processing. The integration of
log-derived permeability and rock type with production data
has provided the basis for interwell heterogeneity prediction
and field-wide completion strategies.
of Lunnan field, an Ordovician carbonate buildup in the Tarim
basin, West China, used 3D seismic visualization, Amplitude Variations
with Offset (AVO), seismic attribute analyses and various well
logging techniques to identify and characterize the reservoir.
CNPC exploration success rate in the field has increased 85%
due to the study. Lunnan field has been producing over 3.5 million
bbl of crude oil annually. In terms of oil in place, Lunnan field
is the biggest carbonate oil field in China.
recent times, explosives had been used to open up and fracture
the reservoir. The technology featured here is a timing device
that allows explosives to be pulsed in a precise manner to
open up fractures through perforations. The result is small
fractures that provide greater drainage for improved production.
Case studies describe the operations and the results for lease
buzz about wireless land seismic data acquisition is ubiquitous.
But is it real? What, exactly, does eliminating wires do for
you? And how is the data quality with the new systems. A review
and discussion of the various systems made by I/O Vibetech
(Sercel), Asend and others sets the data record straight.
easily exists enough natural gas in the world for more than
doubling of LNG volumes. And markets in North America, Europe
and Japan show no sign of improvement in conventional gas
production. If the supply and demand potential is good, why
are so many re-gasification terminals operating at half throttle?
And what’s taking so long?
Reed-Hycalog Rig Census makes its annual appearance. Our industry
is showing signs that newbuilds already ordered are displacing
older rigs. Yet, there is still modest growth in drilling.
All of which makes this year’s report more valuable than
ever. This exclusive report, full of tables and figures, summarizes
the firm’s annual survey of US drilling contractors'
fleet status and key activity indicators. Content includes
Canadian land rigs and some offshore international fleets.
Industry professionals find the census especially valuable
when forecasting day rates or future rig availability.
in cooperation with the Produced Water Society, this month’s
story focuses on Steam-Assisted Gravity Drainage (SAGD). Although
SAGD feed requires 100% quality steam, operators have typically
used Once-Through Steam Generators, which produce 75-80%
quality steam, then run the output fluid through a series of
vapor-liquid separators to produce 100% quality steam for injection.
A new method implemented in Alberta by Deer Creek Energy uses
mechanical vapor recompression evaporation followed by standard
drum boilers. This method is simpler to operate, is more cost-effective
and results in significant increases in equipment reliability,
on-stream availability and, ultimately, increased oil production.
The plant has also achieved recovery of all liquid waste for
reuse, resulting in zero liquid discharge.
