Oil field chemicals
Integrity Management
Crown-Towers -Chem Oilfield offer a comprehensive range of asset integrity management products, solutions and services including field surveys and monitoring. Product classes available include the following:
Corrosion inhibitors, specifically formulated and developed for system conditions, transport pipelines, wet gas lines, subsea flowlines, process applications, water injection and hydrotesting
Biocides for the control and treatment of oilfield bacteria which can lead to microbial induced corrosion, under deposit corrosion and H2S generation. Products are available for water injection, SRP systems, production systems and hydrotesting
H2S scavengers to reduce the H2S content of sour production. Several chemistry types are available and can be used to treat mixed fluid production, gas production or storage vessels.
Oxygen scavengers to reduce the dissolved oxygen content for water injection, SRP systems and hydrotesting.
Flow Assurance
CTCC-csca Oilfield offer an extensive range of Flow assurance solutions, modelling, prediction, monitoring and support work. The main areas we treat include the following:
Scale Management
We provide a comprehensive range of scale inhibitors to prevent mineral scale deposits such as calcium carbonate, calcium sulphate, barium sulphate, iron sulphide. These products can be custom designed for a given system and either continually dosed or squeeze/batch treated dependant on the specific field problem from reservoir through to pipe discharge point. Treatment designs are specifically tailored per application
Scale dissolvers are also available to remove scale already formed. Products can be supplied to remove carbonate, sulphate, sulphide and mixed scales.
Wax control
We have a wide range of wax control additives including dissolver packages, wax dispersants and pour point depressants. These can be selected based on the conditions encountered during production, transportation and storage.
Asphaltenes
We provide product for removal of asphaltene deposits and can supply continual injection asphaltene dispersants and asphaltene squeeze products for application into the reservoir
Hydrates
We can support hydrate management control through the evaluation of system conditions, modelling and predictions which can assist in the choice of technology deployed. We can supply thermodynamic or kinetic inhibitors depending on the levels of subcooling
Naphthenates
Formulated treatments can also be developed where naphthenates contribute to solid deposition and separation issues. Specific treatments are developed on a case by case basis
Foamers
Crown Towers chemicals Co Oilfield has a range of Foamers technologies which can be used for gas well deliquification
Separation Control
CTCC-csca Oilfield is experienced in the treatment of separation facilities with a range of demulsifies, deoilers and foam control additives specifically designed for your system. The products are optimally developed on fresh fluids/emulsion in the field locations by our team of separation specialists, and are designed to meet the requirements of the given system. Monitoring services are also available to track the system over time ensuring fluid characteristics are in specification such as BS & W, salt content, low residual oil in water levels.
Gas Treatment Packages
CTCC-csca Oilfield can supply your needs for gas treatment products. From glycols and amines through to scavengers, antifoams, corrosion inhibitors and scale inhibitors.
