20,000-psi open-water
shear, seal valves to support
GOM HPHT campaign
The RizeRdillo Advanced Jetting Tool allows for higher pump fl ow rates for BOP
cleaning, enabling a larger volume of fl uid with less pump pressure. No damage
was seen with the BOP by using the higher pump rates during the trial period.
Jetting tool enables higher pump rate for BOP
cleaning on Johan Sverdrup, reducing time by half
Odfjell Technology recently trialed a
new procedure for BOP cleaning on the
Johan Sverdrup platform in Norway,
achieving a 50% time reduction during
the six-month test period. The new pro-
cedure involved increasing the pump
rate to allow more water flow into the
BOP cavities to aid debris removal.
The annular and variable rams were
flushed with two passes at the new rec-
ommended flow rates to remove debris,
then the BOP stack was flushed at the
same rate using the RizeRdillo Advanced
Jetting Tool. The flow rates went from
1,500 liters per minute (LPM) to 5,500
LPM while flushing the annular and
from 3,000 LPM to 5,500 LPM while
flushing the BOP. Results from the test
period proved that no damage occurred
to the BOP and annular with the recom-
mended pump rates, and between six
and 12 hours of time could be saved using
this new procedure.
Separately, Odfjell Technology also
announced deployment of a rigless plug
and abandonment (P&A) unit for a geo-
thermal pilot project in Tromsø, Norway.
The project aimed to progress an
underground heat storage concept . The
key objective was to create a network of
subsurface fractures between a center
injector well, along with surrounding
production wells. All wells had been
pre-drilled down to 300-m depth. Odfjell ’s
rigless P&A unit deployed a hydraulic
stimulation assembly, sand jetting and
fracturing the formation every 5-7 m
from 70- to 270-m depth. After the frac-
tures were established, an injection test
confirmed significant flow communica-
tion between the injector well and the
producers .
With this fracture system in place,
Kvitebjørn Varme, the company oper-
ating the district heating facility in
Tromsø, can use the excessive heat pro-
duced from its plant during summer to
warm up water, circulating hot water
down the injector well into the fracture
network and up through the producer
wells. Heat is transferred from the hot
water to the formation, heating the rock
over time. During winter, cold water will
be circulated into the fracture system,
transferring the stored heat to the cold
water. Hot water is produced from the
production wells, ready to be distributed
directly into the district heating network.
NOV bit sets field record in Colombia’s Acordionero field
NOV and Gran Tierra Energy recently
worked together to deploy the Tektonic
Fuego drill bit technology in Colombia’s
Acordionero field, setting a field record
with the Acordionero 98 well.
A 12 ¼-in. TK59 bit equipped with ION
cutters was run on a downhole motor
assembly for a total of 2,446 ft in 2.25
10 hrs, resulting in an ROP of 1,087.1 ft/
hr. Previous PDC bits deployed in the
12 ¼-in. section, which is composed of
claystone and sand, had shown broken
and chipped damage on PDC cutters
and severe erosion on the steel body.
The previous record in the field was
983.2 ft/hr.
Subsea intervention technology special-
ist Interventek is set to supply a complete
set of fully qualified 20,000-psi open-water
well intervention shear and seal valves to
Trendsetter Engineering later this year.
The agreement allows Trendsetter exclu-
sive rights to deploy the 20K, 5 ⅛ -in., open-
water valves for five years .
These 20K Revolution valves are
designed as a compact, modular addition
for lightweight subsea intervention sys-
tems. They will provide the well control
function within Trendsetter’s new 20K
TRIDENT Subsea Intervention System,
which will first be deployed on a high-
pressure, high-temperature (HPHT) subsea
completion and intervention campaign in
the Gulf of Mexico.
Subsea intervention in an HPHT envi-
ronment would normally use hydraulic
gate valves or rams as a well control
solution, but these are larger, heavier and
slower to operate . Interventek’s shear and
seal mechanism uses separate internal
components and rotary actuators to shear
through a range of wireline or coil-tubing
conveyance systems and seal the wellbore
in a single operation. This also allows size
and weight reduction of the assembly .
Interventek previously introduced the
first 20K-rated in-riser safety valve in 2017,
so the open-water variant is a natural pro-
gression, the company said.
46th GOM well intervention,
3 riserless zone perforations
under C-Innovation’s belt
C-Innovation recently
completed its 46th well intervention in the Gulf of
Mexico , as well as three new riserless
zone perforations . The company’s well
intervention program has performed 31
hydraulic interventions and 15 mechanical
interventions since 2017. The mechani-
cal interventions included 85 successful
wireline runs, both e-line and slickline.
C-Innovation also recently completed its
longest mechanical intervention onboard
the vessel Island Venture. With 79 days
offshore, the operation included 22 e-line
and slickline runs, as well as 22,205 bar-
rels of fluid pumped into the well.

Study touts low carbon intensity of US Gulf of Mexico
oil production compared with other parts of the world
A new study indicates that the green-
house gas intensity of US oil production,
particularly in the Gulf of Mexico (GOM),
is significantly lower compared with
most other regions around the world.
The study, commissioned by the
National Ocean Industries Association
(NOIA), found that total US oil production
has a carbon intensity 23% lower than the
international average outside the US and
Canada . Further, the US Gulf has a carbon
intensity 46% lower than the global aver-
age outside of the US and Canada, out-
performing nations like Russia, China,
Brazil, Iran, Iraq and Nigeria.
Using the largest crude category from
the GOM (API Gravity 37.5), instead of
similar crudes from outside the US and
Canada, could halve the average interna-
tional carbon intensity, the study stated.
The report includes a sensitivity analy-
sis of global methane emissions, indicat-
ing that US production, especially in the
GOM, performs much better relative to
the global average in terms of emissions
intensity even when measured using
other methane estimation methodolo-
gies. “The world needs both climate solu-
tions and a growing amount of energy,
and we don’t have to choose between
the two,” NOIA President Erik Milito said.
“ The Gulf of Mexico produces a massive
amount of energy with a remarkably
small footprint, and its continued suc-
cess is critical for our energy security,
national security and energy affordabil-
ity. This study validates the importance
of the US Gulf of Mexico as a source of
energy with demonstrably lower carbon
intensity barrels.”

DNV to support EGPC with
sustainability program
DNV signed a Memorandum of
Understanding with the Egyptian General
Petroleum Corp (EGPC) to support the lat-
ter in its effort to set science-based targets
for net-zero goals. EGPC is setting these
targets within the framework of the “Egypt
Vision 2030” national plan to reach the
country’s sustainable development goals ,
in line with the 1.5°C pathway of the Paris
Climate Agreement.
Both parties will identify the economic,
social and environmental risks, opportuni-
ties and impacts of EGPC’s activities for all
relevant stakeholders .
