However,many such studies tend to be theoretical or, from a riser engineeringperspective, have been applied to simplified academic problems witha single object function. This was an issue RiserTec tackled head on by developing designoptimisation methodologies that were applied to a wide range of realprojects with multiple object functions in most cases.MethodologyRiserTec’s design optimisation methodologies include gradient, non-gradient and population-based methods, as well as simple strategiessuch as random or grid search. In each case the methodology requires definition of independentdesign parameters, design constraints, object function anddesign model. The design parameters span the design space andshould be carefully selected in each case, with the number ofdesign parameters influencing overall complexity and cost of theoptimisation process. Moreover, constraint equations, established in terms of the designparameters, can take many forms. In the simplest cases, one ormore design parameters may be required to lie between specifiedupper and lower bound values.

  10. 10. page 10 InnovOil by vNewsBase November 2012DebuggedOil Plus is developing new techniquesto deal with micro-organisms thatdamage oil infrastructureO 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 suchas reservoir souring (H2S generation) and microbially influencedcorrosion (MIC), which damages the integrity of facilities and maycost billions of US dollars each year in lost production. With those challenges in mind, one UK-based companyhas embarked on a mission to gain a greater understandingof the problematic microbes using state-of the art molecularmicrobiological techniques. Oil Plus, which has been servicing the oil and gas sector for morethan 30 years, has launched a joint industry project with the supportof several international oil companies (IOCs) to tackle the problem.

  13. 13. November 2012 InnovOil by vNewsBase page 13 Piping up Materix has developed a pipe-in- pipe concept to deal with abrasion caused by drill cuttings B 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 Contact: Erik Lenes, CEO Tel: +47 9926 0091 Email: Web:

That is all changing now.Increasingly, integrated gravity and magnetic methods are beingused to complement and constrain traditional seismic data to achievegreater success in oil and gas exploration. Integrated exploration techniques have played an importantrole in the deep offshore oil discoveries in the Gulf of Mexico, theRovuma Basin offshore Mozambique and Brazil’s Santos Basin,uncovering potential locked behind massive salt layers up to 2 kmthick. Gravity and magnetics have been used extensively in sub-saltexploration to integrate with the seismic data and image the base ofthe salt, or to assist in the processing of the seismic data. Combiningseismic and gravity methods is also enabling oil explorers to defineprojects better and focus them early on, and to minimise the risk ofexpensive investigation in frontier areas that have not been exploredextensively in the past. Technology has advanced and adapted to meet the needs ofintegrated exploration. From the interpretation side, there is bettersoftware available to integrate the gravity and magnetics with theseismic and other geophysical and geological data. This kind oftechnological integration has been central to the effective use ofthese methods. In recent years, Geosoft has added significant capabilities tofacilitate closer integration between seismic and gravity datainterpretation. Geosoft’s Oasis montaj platform allows to processpotential data in a unique environment, and provides the abilityto load other data such as seismic and wells to constrain theinterpretation process better. Additionally, Geosoft GM-SYSmodelling capabilities – 2D as well as 3D – provide an easy way tocheck the consistency of a seismic interpretation. Using the varied visualisation tools in Geosoft, oil explorers areable to reduce risk and increase their understanding by looking at as 3D seismic data as the generated density cubes may be used directlymuch different data as they can, in as many different ways as they in the GM-SYS model.

The event boasted 60 exhibitors with more than 450 delegates representing 236companies from around the globe. The event, which was hosted in partnership with the UKDepartment of Energy and Climate Change (DECC), tackled themost pressing challenges in the offshore oil and gas industry fromproduction optimisation through to decommissioning. ITF Director Melfort Campbell said the Technology Showcasewas unique in the way it encouraged face-to-face meetings betweeninnovators and operators to find solutions to problems in the globalindustry. Campbell noted the need for advanced development ofnew technologies such as seismic and reservoir characterisationprocesses and advanced well construction and drilling applicationsand tools. He also said operators had identified the sustainment ofasset integrity and life extension and the delivery of cost-effectivedecommissioning as key areas that would require the application oftechnical expertise in the future. Delivering the keynote speech at the event, Trevor Garlick,BP’s regional president for the North Sea, said that slowing thesharp decline in production rates in the UK Continental Shelf wasimperative and that improved technology was vital to maximisingrecovery.
