Background Information Technical Data. Having both our own elastomers as well as our own manufacturing facilities we are able to supply customers with bespoken articles designed to suit customer well specifics while maintaining a standardised format. Thus offers an optimal cost effective solution rather than a one size fits all type of solution, additionally by being able to choose from a range of different elastomers we are able to tailor make the a solution which exceeds the performance envelopes of 1 st generation equipment. The design of our equipment is not copied from equipment available elsewhere but is specific to the function as well as the actual elastomer used. To be able to supply a sound engineered product we have to be able to test the compound used and verify its mechanical ability, for some items this is a simple Lab test where there is a reasonably well used standardised test. However for most of the swelling compounds there are not tests available and with it no equipment available to be used to measure this. For water swelling elastomer tests of less than 100 Celsius it is mostly a matter of simply measuring the results coming out of a pot in an oven. However for water swelling samples in excess of 100 Celsius things are not that simple as the effects of steam forming are ever present in the test samples for swelling. These therefore conventionally have to be cooled down to less than a 100 Celsius the conduct the mechanical measurements required for design data. This is both cumbersome and is not really giving real data at the temperature being experienced. To enable us to do this we have developed a series of test cells that measure live chemical and mechanical results results at real conditions. Page 2
Design Equipment: As an important part of the design of products we have a number of elastomer testers in use. These are purpose built items that are used to quantify the compounds mechanical characteristics in the compound design phases. Both sets of testers are live testers that measure the characteristics of the elastomer at Temperatures up to 300 Celsius as well as pressures depending on the tests and configurations of above 300 bar. Compound Mechanical Testers Fig 1. Screen shot of our Seal and Compound tester. The above is a screen shot of the computer control used to control and Monitor our 5 Cell Tester, which tests a sample of elastomer of 4 inch diameter and 12 inch length. This unit was designed and developed in house and is pre-programmed for various test sequences to be conducted with automatic live data storage and automatic start up and warming as well as shut down and sleep functions. It is used for a compound test where it takes the basic data obtained from the Compound tester and then builds on this for both a larger size and for scaling analysis. Its second function is NOT for swelling mechanics but for sealing configuration testing, where the correct shape and form of seals can be determined and the effects of changes to these be quantified and analysed.

Compound Tester Fig 3. Compound tester The compound tester is a tester designed more for the chemical engineer aspects of swelling elastomers than for mechanical testing. Here differences in compound and vulcanisation programs can be compared at elevated temperatures and pressures. As with the previous tester this system is totally autonomous and pre-programed tests can be conducted to allow performance comparison. As with the previous test the results are automatically stored for remote retrieval. Page 5
Q-Configurator Outside of the physical product the most crucial section is that of the correct prediction of swelling versus time, Temperature and salinity on water swelling elastomers. This enables the correct elastomer dimensions to be chosen to suit the well conditions and the job at hand on that well. To enable us to do this we have a computer configurator that enables lab swell data to be pulled from LIMS database. By simply filling in the necessary required dimensions on screen the programme generates the predicted swell curves, showing Hole gauge size and washout size plus the intersection of the swelling curves with this. The programme calculates, based on the data, the time to first contact (the moment the elastomer just kisses the well bore) through to the time when full seal has been generated. Page 6

mm Swell Technical Data. LIMS data base Our LIMS data base contains the results of all the testing we have done and do on all RUMA compounds. A large part of that is the testing on Swell performance of compounds. This can be divided into two main sections, Customer specific tests where we have tested for a custom (this is usually Oil, Oil or water based muds or things such as Formate Brines) however this is also reservoir fluid etc where for one reason or another we require the specific data possibly for close tolerance work or disposal wells. Matrix tests where we test to generate to generate the swell matrix for prediction curves. The matrix is a structure of different swell curves for salinity versus Temperature 8 7 6 5 4 3 2 1 0 Different swell rates at different temperature versus Time in days 0 20 40 60 80 100 120 DAYS 20 25 30 35 40 45 50 55 60 65 70 75 80 Fig 4. Typical Matrix curves Fig 4 illustrates a series of curves on a specific rubber at the same salinity with temperature steps. In total there more than an estimates 3000 different swelling tests in our LIMS. Page 9

Graphs Fig 6 Customer graphs. The above graph is for customer use and is a dual axis representation of our Q-Configurator which is being trialled with Customers before we upgrade our Q-Configurator software to the newest version. It shows on the left differential pressure rating versus swell Diameter and on the right hand side the Diameter increase versus time for the specific conditions shown. Indicated are the first contact time and pressure rating. Page 11
Pressure Rating Pressure ratings is a complex factor to calculate because of aspects out of control of the supplier. In few horizontal open hole wells is the swell packer centred properly. The longer the seal assembly the less likely it will be centred due to corkscrewing, undulating of the well and washout. The combination of all of these means the design of the running guides installed on the seal is a critical first step. Whilst we do have standard sizes we are able to specify and supply different sizes to suit specific customer needs. Fig 7 This is our typical Oblique running guide developed for running on long deviated wells. Fig 8 A standard running guide. Outside of the centring, pressure ratings are very much dependent upon the actual bore, which unless it is in casing is itself never ideally round and even then not very round. Page 12
Engineering Technical Support Technical Data. We offer our customers very specific expertise to help them understand both the products being supplied as well as to help with any technical queries they might have. Because the equipment being supplied consists of two totally different engineered sections we offer technical advice and support for both disciplines. In the case of both these this extends not only to use of our products but is also a more general level as we note that knowledge on elastomers is limited and it is in our view important that this be available to well engineers. We would normally turn around a question within 24 hours and often this is within a couple of hours. Page 13
