optimisation technology – which has been around for many years
– provides an economic solution to this problem while offering Vessel Stand-off
significantly improved operator risk management. 15m
The technology has been well documented in literary work,
including studies related specifically to riser design. However,
many such studies tend to be theoretical or, from a riser engineering
perspective, have been applied to simplified academic problems with
a single object function.
This was an issue RiserTec tackled head on by developing design
optimisation methodologies that were applied to a wide range of real
projects with multiple object functions in most cases.
Methodology
RiserTec’s design optimisation methodologies include gradient, non-
gradient and population-based methods, as well as simple strategies
such as random or grid search.
In each case the methodology requires definition of independent
design parameters, design constraints, object function and
design model. The design parameters span the design space and
should be carefully selected in each case, with the number of
design parameters influencing overall complexity and cost of the
optimisation process.
Moreover, constraint equations, established in terms of the design
parameters, can take many forms. In the simplest cases, one or
more design parameters may be required to lie between specified
upper and lower bound values. In more complex forms, the design
associated with any realisation of the design parameters may be
required to have a maximum stress below a specified allowable
value over a set of defined static load conditions.
The object function, again defined in terms of the design
parameters, represents that which the process is attempting to
minimise (or maximise).
One example might be the maximum curvature along the riser
enveloped over a series of defined dynamic load cases. In many
cases, multiple object functions may be involved, such as the
requirement to minimise hang-off load on the platform while at the
same time minimising maximum riser curvature along the riser.

Oil Plus is developing new techniques
to deal with micro-organisms that
damage oil infrastructure
O
ne of the most overlooked challenges facing upstream
developers is the micro-organisms that inhabit oil
reservoirs and the resulting problems they cause.
Micro-organisms are behind complex problems such
as reservoir souring (H2S generation) and microbially influenced
corrosion (MIC), which damages the integrity of facilities and may
cost billions of US dollars each year in lost production.
With those challenges in mind, one UK-based company
has embarked on a mission to gain a greater understanding
of the problematic microbes using state-of the art molecular
microbiological techniques.
Oil Plus, which has been servicing the oil and gas sector for more
than 30 years, has launched a joint industry project with the support
of several international oil companies (IOCs) to tackle the problem.
In the past, the micro-organisms behind H2S generation and

Materix has developed a pipe-in-

ergen-based Materix has developed an
innovative range of Wear Resistant Pipe Fittings
(WRPF) lined with silicone carbide (SiC) that guard
against wear and tear from drill cuttings.
The company, founded in 2008, uses a “pipe-in-pipe”
concept, which sees an inner ceramic pipe act as the exposed
wear component, thus protecting the outer pipe from
abrasion.
Drilling fluid containing quartz and other hard
particles is conveyed at high velocity in pneumatic
pump systems.
SiC is the third hardest ceramic material and
exhibits superior erosion and corrosion resistance
properties. WRPF elbows can thus withstand
aggressive high-velocity particle flow with
multiple lifetime gain compared with traditional
steel pipe fittings. The main product comprises
ultra-compact short-radius elbows for the reliable
conveyance of drill cuttings.
The Materix solution bonds SiC to metals
and makes the assembly reliable where thermal
gradients and pressure prevail.
In the field
The products offered are designed for use in
extremely harsh environments. During field testing,
the technology was qualified in a pneumatic transport
system for drill cuttings on Norway’s Gullfaks field
in 2011, with fluid velocities of 50-100 metres per
second. Tests were conducted during the drilling of
three wells on Gullfaks in co-operation with an oil
service company.
After five weeks, three wells and 230 cubic metres
of abrasive flow, no reduction of the wall thickness of the
ceramic liner could be observed. In addition, 12 conventional
induction-formed long-radius sweep bends in the same system
were changed as a result of leaching and wear.
In high-speed pneumatic conveyance systems, the wear in
bends is significant, with subsequent frequent replacement of failed
components and system downtime.
In order to lower the friction further it is common to add base oil
to the cuttings prior to their conveyance. This doubles the volume
shipped to onshore processing, with consequent cost increases in
freight, handling and processing.
Wear-resistant elbows will facilitate the conveying of dryer
cuttings with significant volume and mass savings, as there is no
need for added lubricants. n

Unlocking potential
through integration
Geosoft aids closer integration between seismic and gravity data interpretation
W
ithin oil exploration there was a time when gravity
and magnetic surveys were considered the coarser,
rougher first cut to zeroing in on the best locations
to set up seismic gear. That is all changing now.
Increasingly, integrated gravity and magnetic methods are being
used to complement and constrain traditional seismic data to achieve
greater success in oil and gas exploration.
Integrated exploration techniques have played an important
role in the deep offshore oil discoveries in the Gulf of Mexico, the
Rovuma Basin offshore Mozambique and Brazil’s Santos Basin,
uncovering potential locked behind massive salt layers up to 2 km
thick.
Gravity and magnetics have been used extensively in sub-salt
exploration to integrate with the seismic data and image the base of
the salt, or to assist in the processing of the seismic data. Combining
seismic and gravity methods is also enabling oil explorers to define
projects better and focus them early on, and to minimise the risk of
expensive investigation in frontier areas that have not been explored
extensively in the past.
Technology has advanced and adapted to meet the needs of
integrated exploration. From the interpretation side, there is better
software available to integrate the gravity and magnetics with the
seismic and other geophysical and geological data. This kind of
technological integration has been central to the effective use of
these methods.
In recent years, Geosoft has added significant capabilities to
facilitate closer integration between seismic and gravity data
interpretation. Geosoft’s Oasis montaj platform allows to process
potential data in a unique environment, and provides the ability
to load other data such as seismic and wells to constrain the
interpretation process better. Additionally, Geosoft GM-SYS
modelling capabilities – 2D as well as 3D – provide an easy way to
check the consistency of a seismic interpretation.
Using the varied visualisation tools in Geosoft, oil explorers are

ITF’s Technology Showcase’s
reputation as a key event for
oil industry innovators and
operators continues to grow
I
TF’s fifth annual Technology Showcase welcomed its largest
number of delegates and exhibitors at Aberdeen Exhibition
and Conference Centre on November 1. The event boasted
60 exhibitors with more than 450 delegates representing 236
companies from around the globe.
The event, which was hosted in partnership with the UK
Department of Energy and Climate Change (DECC), tackled the
most pressing challenges in the offshore oil and gas industry from
production optimisation through to decommissioning.
ITF Director Melfort Campbell said the Technology Showcase
was unique in the way it encouraged face-to-face meetings between
innovators and operators to find solutions to problems in the global
industry. Campbell noted the need for advanced development of
new technologies such as seismic and reservoir characterisation
processes and advanced well construction and drilling applications
and tools. He also said operators had identified the sustainment of
asset integrity and life extension and the delivery of cost-effective
decommissioning as key areas that would require the application of
technical expertise in the future.
Delivering the keynote speech at the event, Trevor Garlick,
BP’s regional president for the North Sea, said that slowing the
sharp decline in production rates in the UK Continental Shelf was
imperative and that improved technology was vital to maximising
recovery.
Garlick said the average recovery rate from North Sea reservoirs Glasgow Caledonian University (GCU) and Shearwater Marine
was around 40%, meaning that more is left in the ground than is Services Ltd have unveiled a new form of video and technical
