Roemex is one of the world’s leading completions
chemical 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 PRODUCT
LIST page includes a description of each of our main products.
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 detailed account of operations to be collated
and reported. Information contained in these operational reports
includes performance related data and associated statistics
for well cleaning operations.
Detailed information 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
Why are wellbore clean ups important?
A clean wellbore prior to running completions
is essential for two main reasons:
Firstly, subsequent operations, such as setting packers, running
screens, etc can be problematic in a wellbore that is not
clean, leading to failures, re-runs etc, all of which takes
up valuable rig time. Hence a bad clean up or no clean up
at all can lead to a much higher bill for constructing the
Secondly, if the well is not clean prior to perforating
or prior to running screens or gravel packs, the solids
and emulsions that are left behind can have a severe effect
on well productivity. These solids or emulsions can block
formation sands leading to high skin factors or block screens
or gravel packs, leading to “hotspot” production and hence
to early failures of these sand control devices.
