Roemex is one of the world’s leading completions chemicals companies. We provide speciality chemicals to clean the wellbore prior to completing the well, whether in cased-hole or open-hole environments. We also provide highly efficient inhibitors and additives for completion fluids.
The objective of Roemex is to exceed the expectations of clients in well cleaning operations. Our goal is to perform well clean-up operations in the most efficient manner possible, and to identify and recommend continual improvements. Offering the most fit-for-purpose system continues to underline the basis of Roemex job design.
Detailed monitoring and information gathering from all operations where a Roemex engineer has been present, has allowed a database of operations to be collated and reported. Information contained in these operational reports includes performance related data and associated statistics for well cleaning operations.
Data is stored on a well-by-well basis. This information details factors which beneficially and detrimentally contributed to the operations. The information in the database is used to enhance future operations by identifying all areas which contribute in either positive or negative manners. Roemex is determined to work closely with our customers to continually improve performance.
A clean wellbore prior to running completions is essential for two main reasons:
Wellbore cleaners are a significant part of Roemex’s business. This line of products also translates into pipeline cleaning products and rigwashes. Roemex has vast experience in testing and evaluating this type of product. Roemex utilises a Surface Tension Balance for surface tension and interfacial tension measurements.
Roemex provide many chemical solutions to the oil and gas industry; included in this are our highly effective range of lubricants and friction reducers. We supply not only lubricants for water, brine and water based muds but we also produce a base oil and oil based mud liquid friction reducer.
The products have helped clients all over the world meet their well objectives in the following ways;
In all these cases, and many more, Roemex were able to provide the solution.
At Roemex we pride ourselves in being able to meet and exceed such clients’ expectations. We started with one lubricant in our portfolio but we soon expanded this as we were requested that this lubricant not only meet the friction reduction criteria but also more specific targets such as use in formate brines or being non-damaging in open hole environments. Continual research and development will lead us to even more case specific lubricants and friction reducers
Roemex have several products that have been proven time and time again to be extremely effective wellbore clean-up chemical and completion fluid additives. Our tried and tested products are listed below. However, as a flexible independent company dedicated to exceeding the requirements of our clients, we can produce new chemicals relevant to specific needs, on an individual basis.
We also provide a number of our products and services for workover and re-entry wells:
Selection of a particular product is dependent on application and customer requirements. Roemex representatives should be contacted for advice on product selection.
Lubricants are used during drilling and coiled tubing operations to reduce torque (rotary friction) and drag (axial friction) in the wellbore.
Due to increasing focus on efficient drilling practices plus challenging extended reach, high angle and deep water wells being drilled today, lubricants are becoming a necessity for drilling, completion, wellbore clean-out, wireline operations, coil tubing operations, running production tubing etc.
Roemex can provide several lubricants for these applications; Brine Lubricant RX-72TL is a premium product in our wide range of lubricants, it is a blend of non-ionic and anionic surfactants in an aqueous solution which has an excellent environmental profile.
In addition to the product’s excellent environmental profile, the product is not classified for transportation meaning that it can be shipped without a dangerous goods declaration.
Brine lubricant RX-72TL is designed to reduce metal/metal and metal/formation friction in wellbores. It is stable and soluble in most completion brines and exhibits good compatibility with nitrile and other common elastomers. Brine lubricant RX-72TL also demonstrates good thermal stability.
Brine lubricant RX-72TL is normally deployed in seawater or completion brines. Typical applications are:
