EDITORIAL
Both technology and fossil hydrocarbons (oil and
gas) are assets of high strategic value for any
particular society or nation. Technology, in the form
of products, processes and knowledge, is as old as
man and has a broad spectrum of application,
ranging from solutions for the best quality of life of
people.
The strategic importance of oil in modern times lies
in its civil uses. Most nations rely heavily on oil and
gas. And while the technology for its use is widely
developed and globalized, the technology for the
search, extraction and refining of oil is much less
widespread. It follows that not only the physical
resource (the barrels); but also the technology
necessary for the exploration, production and
refining of oil and gas; and the specialized human
talent and capable of administering these
technologies, are of the highest value. These three
elements are of great geopolitical influence and
having them is an advantage.

EARTHSTAR® ULTRA-DEEP RESISTIVITY SERVICE GEOMAPS MULTIPLE OIL SATURATION

ZONE
A major oil and gas operator in southeast Asia
drilled extended-reach smart wells for oil
recovery in a narrow 10-kilometer x 2-kilometer
(6.2-mile x 1.2-mile) carbonate pinnacle
reservoir. These thin oil rim development wells
were challenging because of high uncertainty in
reservoir structural depth and production
performance, with no history or comparable
analogues as reference. Additionally, the
horizontal well placement was targeted at the
middle of the oil zone, with a specific standoff
from the gas-oil contact, which had high true
vertical depth (TVD) uncertainty.
The key performance indicators (KPIs) for
these wells included:
» Drilling the 8½-inch lateral drain with minimal
undulation for ease of running the completion
string
» Achieving all logging-while-drilling (LWD)
requirements across the target interval
» Delivering flawless execution with minimum
non-productive time
EARTHSTAR SERVICE ENHANCES RESERVOIR
UNDERSTANDING
The Halliburton Sperry Drilling team recommended
the EarthStar® ultra-deep resistivity service, which
features a high signal-to-noise ratio arising from
state-of-the-art engineering. This technology is
proven to detect and map reservoir structure and
fluid boundaries up
to 225 feet (68 meters) from the wellbore. For this
particular operation, the EarthStar service resolved
multiple complex fluid boundaries, delineating the
gas-oil boundary and also resolving two distinct
low-resistivity signatures – thus defining the oil-
water contact. Additionally, a detailed pre-well
model, using multiple offset wells and various
possible
geologic structural models, further assured the
operator that the EarthStar service would be able to
resolve the targets clearly.
ACCURATE WELL PLACEMENT AND
GEOMAPPING MAXIMIZE ASSET VALUE
The 12¼-inch hole sections of the Phase 1 drilling
campaign were landed geometrically at the mid-
point of the thin oil rim, based on a base-case, gas-
oil contact. Thereafter, the long 8½-inch horizontal
sections were drilled with minimal undulation within
the +/- 5-foot (1.5-meter) TVD target window, as
specified by the operator, to facilitate running the
completion string. The wells were executed
efficiently with each hole section being drilled
6. Successful Dual Drilling OperationsSaves Aker
BP USD 1.2 Million with Zero HSE Issues
THREE SIMULTANEOUS DUAL DRILLING OPERATIONS REDUCE WELL TIME AND
ATTAIN WORLD-FIRST RECORD
NORTH SEA, NORWAY
In collaboration with Aker BP,
Halliburton Sperry Drilling
planned and drilled two wellbores
at three different proximal
locations in the North Sea,
offshore Norway near Stavanger. A
prerequisite for each location was
to first drill a pilot hole to
evaluate
the presence of shallow gas.
Typically, the conductor hole is
drilled before a pilot hole,
followed by the opening of the
pilot hole for running the outer-
diameter (OD) casing.
The deepwater rig had a dual
derrick design, with full drilling
capacity in both derricks. Since
the derricks’ well centers were
approximately 33 feet (10 meters)
apart, it was decided in the
planning phase of pre-operations
to drill two wells simultaneously:
the “pilot-hole shallow-gas”
wellbore and the “main”
wellbore. While this initiative
was thought to be efficient and
time saving, it could also
potentially introduce risk factors.

Saves Operator USD 700,000
XBAT™ SERVICEPROVIDES ACCURATE TOP OF CEMENT EVALUATION
DURING CEMENTING OF LINER
OVERVIEW
Acoustic logging-while-drilling (LWD) tools
can be used to provide an assessment of
top
of cement (TOC), offering an alternative
to a conventional wireline cement bond
log (CBL). During the cementing of a
75⁄8-inch liner in an ultra-deepwater
Gulf of Mexico well, the operator could
not establish cement returns during
pumping operations.
The final differential pressure of 150 psi
during cementing was less than the
planned 180 psi, and, based upon the
cement lift pressure, the operator
anticipated the cement column to be
less than planned by approximately 150
feet (46 meters). Foreseeing cement
integrity issues, the operator planned to
perform a cement squeeze job following
a cleanout run, and also planned to use
a wireline CBL, run on a tractor, to
confirm the TOC.
XBAT™ SERVICE HELPS REDUCE WELL
TIME THROUGH EARLY TOC DETECTION
During the cleanout run to drill the
cement inside the liner, a complete fluid
displacement was performed. The XBAT
azimuthal sonic and ultrasonic LWD
service was included in the drill-out
assembly, and was used to log inside
the casing during both the trip-in pass
and
trip-out pass while the liner was
pressurized differentially. A wireline CBL
was run following the displacement, but,
since it was not possible to perform a
pressurized logging pass, the presence of
the microannulus could not be
confirmed.
8. Toc analysis performed inside 75⁄8-inch casing during the trip-in pass of a cement cleanout run (left) compared to the
trip-out pass (right). The trip-out pass occurred with lighter mud than the trip-in pass, following displacement of the
drilling fluid.
WAVEFORMS AND CASING ARRIVAL ANALYSIS CONFIRM TOC
The XBAT service acquired acoustic waveforms during the cleanout run inside
the liner to assist with the identification and confirmation of TOC acquired by
the wireline CBL.The tool was programmed
to fire two high-frequency monopole modes and to acquire data in memory at a
fast sample rate to ensure sufficient data density without the need to slow
down the tripping operations. TOC was identified at around X9,650 feet, based
on based upon four different datasets acquired from the two different firing
modes and from both trip-in and trip-out logging runs. The waveform analysis
and casing arrival analysis complemented each other in confirming the TOC
depth, and helped to identify a micro-annulus, in contrast to the wireline CBL
data, which was inconclusive.
As a direct result of the LWD analysis, the operator resumed normal drilling
operations in the next hole section without the need for the cement squeeze,
and confirmed the suitability of the XBAT service for future TOC evaluation
applications.
9. Tecpetrol Optimizes Location of Fracturing
Zones and Lateral Placement Using LithoFlex
Service
Optimize drilling and completion strategy with cost-efficient solution
The Vaca Muerta Formation in Neuquén, Argentina, contains complex Mesozoic shales
and is rich in tight oil and gas but requires multiple data sets to understand production
potential. Tecpetrol needed to evaluate production potential in a vertical well in the
formation to optimize drilling and completion design; however, well conditions
precluded running wireline. Tecpetrol sought a cost-efficient solution that would
provide an accurate evaluation of rock heterogeneity to assess production potential,
support hydraulic fracturing operations, and help place the lateral.
Evaluate rock heterogeneity from cuttings
Schlumberger recommended using the LithoFlex service to provide a cost-efficient near-
real-time formation evaluation using the HRDM, XRF, and DRIFTS components. Together,
these components provide accurate and comprehensive measurements of lithology,
mineralogy, and elemental composition from cuttings, enabling a well-informed
comparison of rock heterogeneity. By accurately capturing the geochemical fingerprint
in the vertical well, fracturing operations can be optimized, and the best productive
intervals can be used to guide lateral placemen
10. HEAL System Increases Production More
Than 75% from 25 Montney Shale Wells
The horizontal enhanced artificial lift system—
the HEAL System—guides production from the
horizontal section into a sized regulating string
(SRS) in the build section. Production flows up
the SRS, where it is conditioned into a
stabilized multiphase state, lowering fluid
density, lifting liquids, and mitigating slugs.
The conditioned flow is delivered to a vortex
separator, which separates gas and solids from
the liquid. The gas rises through the annulus
and conditioned liquids are drawn up the
vortex separator and delivered to the pump
located in the vertical section. Extremely
efficient downhole separation and consistent
flows minimize gas interference and gas
locking to maximize pump fillage; the system
also maintains a very low bottomhole
pressure, enhancing drawdown to increase
production. As a result of these benefits,
smaller pumping equipment can efficiently
achieve higher production rates, reducing unit
lifting costs.
Production rate increased in excess
of 75%
The HEAL System increased long-
term (>12 months) production by
more than 75% in the 25 wells,
compared with the previous
production decline trend. Average
incremental production was 18,400
BOE per well in the 12 months after
the system was installed. As a result,
the operator recovered the cost of
each HEAL System installation in just
2 to 4 months.
11. SIMplus Retrievable Bridge Plug Installs
Reliable Barrier for Sealing Tubing Leak
Diagnose and remediate leak in constrained operating conditions
An operator suspected possible communication between the casing and tubing in a
well offshore Venezuela. The typically limited space on the production platform
necessitated performing the diagnosis and remediation on slickline. However,
conducting well intervention techniques on conventional slickline could not provide
precise depth placement, much less real-time control and monitoring capabilities to
confirm operations.
Perform digital slickline operations with real-time control and monitoring
LIVE digital slickline services pair the simplicity and compact footprint of slickline
operations with real-time digital telemetry to deliver relevant downhole
measurement data to the surface in real time for significant improvements in control,
quality, and safety. These capabilities enable running real-time production logs on
LIVE PL digital slickline production logging services where previously memory logging
was the only option.
The SIMplus retrievable bridge plug is an expandable barrier that can be deployed on
slickline, electric line, coiled tubing, drillpipe, or tractor to install a high-performance
seal in fluid- and temperature-cycling environments. The SIMplus plug is the only plug
that can be mechanically set by conventional slickline jarring and has achieved a
14310:2008 grade V3 rating to provide operators with reliable conformance to the
most stringent well barrier criteria. Its advanced setting mechanism and large internal
diameter make it the ideal sealing solution for leak detection and remediation.
