Roemex has an extensive database on all clean-up operations undertaken including performance related data and associated statistics. The data is stored on a well-by-well basis and is used to enhance future operations ensuring continual improvement in performance.

Please contact our representatives for specific recommendations.

RX-Vis & RX GreenVis

R

Viscosifiers based on suspensions of Xanthan gum and Xanthan gum derivates.

R

Increases rheology and hole cleaning when used together with Roemex well bore cleaners and dissolvers.

Although % solids and NTU’s give an indication of well cleanliness they are only confirming that the fluid returns are within specification not that the wellbore is clean.

The only true confirmation of well cleanliness is the pipe and tools that came out of the well after the wellbore clean up.

Leak detection

RX-9022 Pink Dye liquid

The most frequently used dye product. Excellent environmental profile, high visibility.

RX-9026NB Clear Dye
Clear Pipedye offers an advantage over more familiar leak test tracers in being invisible to the naked eye, i.e. non-fluorescent under received white light whilst being very strongly fluorescent under tuned UV light.

Therefore, the obvious visible presence of discharged test solutions either at sea or in tidal waters is avoided. RX-9026NB is not visible with the naked eye; special detection equipment is required. Roemex representatives can advise on this.

Dissolved Oxygen Testing or Combined DO2/LPR/pH
Roemex use Hach Orbisphere electrochemical sensors in the laboratory which enable screening and performance testing of hydrotest chemicals and oxygen scavengers for efficiency in a variety of water types. This technique can be coupled with LPR tests and pH in one cell so that all 3 parameters can be measured at the same time.

Also available in sticks:

R

RX-9034A, Pink dye stick. RX-9034A is the solid version of RX-9022.

Oxygen scavengers:
R

All of our oxygen scavengers are registered with CEFAS and have Gold, no Sub ratings

RX-9034A, Pink dye stick

Corrosion inhibitors and Liquids

RX-5720
A solid corrosion inhibitor that can be supplied for long term corrosion protection (up to 25 years). This product is a solid fatty amine which acts as a persistent film forming corrosion inhibitor. RX-5720 is also available as a liquid version, RX-5718.

RX-5722
A combined solid Oxygen Scavenger and Corrosion Inhibitor. RX-5722 is typically supplied in 34mm diameter water soluble tubing. The oxygen scavenger in RX-5722 removes dissolved oxygen from seawater on contact.

The corrosion inhibitor in RX-5722 is a solid fatty amine-based Corrosion Inhibitor. Quaternary ammonium compounds are good film forming corrosion inhibitors; which means the residual will form an amine film on exposed metal surfaces, thus providing a good excess residual inhibition in the system. RX-5722 has been specifically designed for ROV handled and insertion into specific anchored joints. The Stick is contained in a PVA water soluble tube and film wrapped to control dissolution.

Linear Polarization Resistance (LPR) Bubble Test
Linear Polarization Resistance (LPR) is a commonly used technique carried out as a rapid screening technique on a large number of inhibitors before submitting for further test work. There is capability for conducting tests under sweet or sour conditions and at temperatures up to 95°C. Partitioning evaluations can also be carried out using the LPR equipment.

Static Coupon Tests
It is important to evaluate the long-term performance of corrosion inhibitors intended for long term protection. In order to do this, we carry out static coupon tests using commonly found metals. The coupons are immersed in seawater or potable water containing the hydrotest chemicals being tested. They are then given a nitrogen blanket, stored at 4°C and are monitored for up to 5 years.

Dissolved Oxygen Testing or Combined DO2/LPR/pH
Roemex uses Hach Orbisphere electrochemical sensors which enable screening and performance testing of hydrotest chemicals and oxygen scavengers for efficiency in a variety of water types. This technique can be coupled with LPR tests and pH in one cell so that all 3 parameters can be measured at the same time
