CARBO
The oil and gas industry is taking unprecedented steps towards
digital transformation. Data analytics, AI, machine learning and
process automation are nowcommonplace terminology. As
drilling contractors and operators alike have embraced amore
technologically engaged oil and gas landscape, newchallenges
have emerged fromthe substantial amounts of data being gathered
pre-, during and post-completion. Bringing field data to the office in
an efficient and visual manner and storing it in one location is one
such challenge.
, a real time frac data visualisation platform, was
developed by CARBO to process high quantities of data quickly
and allow for better insights into awell’s performance, enhancing
operational efficiencies and enabling organisations to realise the
value in their completions data. Focusing on the completions
phase of thewell, the platformreducesmanual datamanipulation,
transformation and cleansing. The technology connects to other
FRACPRO software, enabling real time online frac job data display
while centrally gathering completions data into a secure cloud
data repository. An open application programme interface (API)
enables data feeds to and fromother platforms. The platform
will continuously streamthe completions data to cloud storage
for instant and secure access available anywhere. Data related
to fracture design and execution, including downhole pressures,
depths, surfaces pressures, diagnostic fracture injection tests (DFITs)
andmany other data channels, are securely stored and instantly
accessibleminute-by-minute and stage-by-stage. Engineers or
data scientists can upload historic completion-related data from
other sources (e.g. data files, spreadsheets, flat files or any other
digital format) to it. With organised high-quality completions data
in one place, engineers and data scientists can spendmore time
analysing, thinking and realising the hidden value in their data and
significantly less timemassaging andmoving data.
The system is production ready and has been purchased
by several customers. Demo licences have also been issued to
prospective customers.
EnventureGlobal Technology
Enventure Global Technology is a provider of solid expandable
solutions for the energy industry. Solid expandable technology
can be used for multi-stage fracturing to fracture unlimited zones
or sections, and provide a large inside diameter to accommodate
larger perforating guns and flow areas as well as larger frac
volumes and rates.
Solid expandable refrac liners are amulti-zone isolation
completion solution that use solid expandable technology and
elastomer technology to enhance fracturing operations. In addition,
refrac products support any type of perforating, plug and fracturing
programme, fromconventional shaped charge perforation on coil
to pump down composite plugs for isolation. These solutions also
allow for the creation of multiple newperforation and fracture
intervals or zones to support refracturing programmes.
Expandable refrac liners have two advantages over
conventional refrac liners. First, because they can be anchored to
the base casing, they remove the need to performa cementing
job. Secondly, after expansion, they preservemost of the well’s
inner diameter (ID). Larger ID reduces pressure loss due to
friction, which in turn, allows the operator to use higher flow rates
when fracturing. For example, when a 3.5 in. liner (2.992 in. ID)
is installed and cemented within a 5.5 in. production liner, flow
rates can be limited to 40 bpm to 50 bpm (depending on the
required treatment pressure, lateral length, true vertical depth
[TVD] and type of fluid used). A 4.25 in. expandable liner will have
a post expanded ID of 4 in., which under the same conditions, can
achieve 80 bpm to 90 bpmwhilemaintaining the target treatment
pressure, which typically exceeds 10 000 psi.
With the number of refracture operations growing in recent
years, the use of expandable liners as amethod of mechanical
zonal isolation has also increased. Expandable liner companies
have completed numerous successful refracture installations in
most basins in the US.
During this growth it was learned that improvements were
needed in expansion technology – along with pre-planning
collaboration with the operator – to perform installations in
more extreme environments. In collaboration with its clients, the
company has extended the safe operating windowwith a tiered
offering of expandable liners to provide zonal isolation, ranging
fromvertical refractures to long horizontals and now into higher
temperature environments.
Frank’s International
Frank’s International offers tubular running services, tubular
fabrication, and speciality well construction and well intervention
solutions with a focus on complex and technically demanding
wells tomeet the demands of the rapidly changing oilfield. The
company has developed equipment for installing corrosion
resistant alloy (CRA) tubulars that extend the life of the well safely
and efficiently.
The collar load support system for stands of tubing
(CLS-S) is a robust non-marking tubular handling system that
accommodates a wide range of pipe sizes. The systemallows the
running of threaded and coupled stands of tubulars as well as
single joints without causing damaging dye penetrationmarks.
In doing so, it removes the potential for corrosion cracking
due to stress concentrations. Further, the risk of slip crush and
iron transfer is minimised as the systemenables the tubular to
be supported by the load face and not by penetration, thus
avoiding the slippage issues prevalent on certain alloys with
conventional inserts. In addition, there are significant time savings
to be achieved from running stands as opposed to single joints.
Casestudy
On a recent job the CLS-S was used to run 5½ in. Super 13 Chrome
completion stands on amulti-well project for a supermajor in the
North Sea. In combination with the FLUID GRIP® Tong, the CLS-S
was deployed to run the 14 600 ft high pressure high temperature
(HPHT) completion, achieving a time saving of approximately
32 hours. This systemwas chosen specifically for its non-marking
capability while running Super CRA.
The smallest version of the systemhas been designed for
the 27.5 in. rotaries that are typical to the onshoremarket.
