Recent trending has indicated that future land rigs will be set
up to run and build stands of tubing in order to reduce run
times. Along with the highmarket demand for a non-marking
systemon complex wells (e.g. HPHT, sour, etc.), the recent influx
of these onshore wells and the ongoing need for solutions to
facilitate operations in corrosive environments will continue to
propel future adaptive iterations of the CLS and complementary
technologies.
Halliburton
Halliburton helps its customers maximise value throughout
the lifecycle of the reservoir – from locating hydrocarbons and
managing geological data, to drilling and formation evaluation,
well construction and completion, and optimising production
throughout the life of the asset.
The DataSphere® permanent monitoring suite provides
customisedmonitoring solutions to optimise production in
real time. The systemoffers wireless transmission of power and
communication across well tubulars, using inductive coupling
technology. This enables operators to place permanent gauges
behind casing, providing access to real time pressure and
temperaturemeasurements frombehind the casing without
a penetration.
In a completedwell, the A-annulus is the area between the
production tubing and the smallest casing string. A typical well
will also have a B- and often a C-annulus between the different
casing strings. These annuli do not normally have any connection
towellbore fluids, butmaintaining pressure in them is essential to
ensuring the integrity of the casing strings. LinX systemtechnology
enablesmonitoring of these trapped annulus spaces in subseawells
to verifywell integrity, andwith that, maximisation of production
constrained by thermally induced annulus pressures.
When installed behind casing and in direct contact with
the formation, the systemallows monitoring of almost any
section of the formation along the wellbore. This reduces the
risk of out-of-zone injection, and allows monitoring of injector
connectivity between wells and communication between
reservoirs during production.
The ability to provide data in real time with the well flowing
lowers the financial threshold to obtaining data that is key to
field optimisation; otherwise, the only option is often to drill and
complete dedicatedmonitoring wells at great cost.
The system is HPHT-rated and can provide tubing and annuli
measurements all on the same downhole cable and topside
interface card.
The systemhas recently been deployed to determine
communication between injectors and non-producing formations,
where it provided decision-making data in the planning of future
wells and reservoir optimisation strategies. It was installed at
6300mmeasured depth (MD).
The systemhas also recently been deployed to determine
communication between a producing and non-producing zone
during production. The systemwas installed at 3000mMD
and provided communication from the A-annulus through to
the C-annulus.
NexTierOilfieldSolutions
NexTier Oilfield Solutions is a provider of integrated
completions, focused on accelerating production in demanding
US land basins. The company’s completion services include
coiled tubing, cementing, fracturing services, pumping services,
wireline and perforating services, wellsitemake-up and pressure
testing.
As it becomes ever more important to boost efficiency
and improve environmental performance, the company
is increasingly deploying technologies that reduce diesel
consumption and the release of carbon emissions. Among these
initiatives are: incrementally adding Tier 4 dual-fuel engines
to the current Tier 2 fleets; incorporating additives that make
diesel burnmore cleanly and with greater power output per
gallon; undertaking a digital transformation to enhance the
effectiveness of equipment monitoring, increase operational
reliability and provide increased visibility for customers; and
evaluating electric-powered and natural gas-driven pump
designs.
TheHibernate
TM
warm-start systemautomatically turns off
frac pumps between stages and enables remote group restarts
froma data van. Recently deployed over 62 days on aWest Texas
fleet, pumps equippedwith the systemreduced total engine
hours by 34%and decreased engine idling by approximately 54%,
compared to pumps in the same fleet operated using traditional
methods. On an annual basis for a full fleet, these results translate
to fuel andmaintenance savingswithin the seven-figure range.
In addition, the systemdecreases personnel exposure to heavy
machinery, improves onsite air quality and reduces noise.
To further improve efficiency and reduce operational
expenditures, it is recommended to combine wireline and
fracturing services on the same job. Across the US, integrating
these essential services in partnership with the company has
resulted in an average of 20%more stages completed per day.
NOV
National Oilwell Varco (NOV) offers intervention technologies and
a range of stimulation packages. In response to the longer laterals
required inmany shale operations, the company has focused on
helping achieve themaximum returns for customers’ wells.
The Genesis
TM
line of high-capacity coiled tubing units
helps streamline logistics, allows customers to legally carry
more pipe to the site, and can feature the newest Hydra Rig
TM
injector, the HR-6120, which was specifically designed to handle
quench-and-tempered coiled tubing.
