- Exploration: The identification and assessment of potential oil and gas reservoirs.
- Development: The design and implementation of methods to efficiently extract oil and gas from these reservoirs.
- Production: The management of the extraction process, including the transport of crude oil to the surface and its storage.
These phases collectively define upstream operations, focusing on the discovery, extraction, and initial handling of hydrocarbons.
Components & Range of Upstream Drilling & Mud Chemicals
Upstream exploration involves a range of methodologies and techniques to identify and evaluate potential well sites for crude oil extraction. These processes include geo-mapping, surveying, soil sampling, coring, seismic imaging, and downhole logging—all of which are complex, costly, and require high precision for successful execution.
Exploration activities related to potential well sites can be classified into two main categories:
- Onshore: Activities conducted on land, away from water bodies.
- Offshore: Activities carried out beneath the sea or ocean bed.
At Chemtex, we leverage our advanced expertise to provide specialty chemicals that meet the diverse conditions and stringent specifications of various well sites. Our chemical additives are specifically formulated to ensure optimal rheological properties, suspension stability, fluid loss control, wellbore cleaning, and other critical functions necessary for efficient upstream exploration and production.

Upstream Production
Following exploration and development, the production phase begins, where pipelines are installed to connect storage tanks to crude oil or gas reserves located beneath the soil or seabed, facilitating the extraction of hydrocarbons.
As hydrocarbons flow to the storage tanks, gases such as carbon oxides, hydrogen sulfide, and water vapor, in both fluid and vapor phases, are also released. These contaminants not only degrade the quality of the crude oil but also pose significant corrosion risks to the metallic structures of the pipelines and storage tanks. Chemtex offers a range of upstream production chemicals designed to mitigate these corrosive threats, ensuring optimal protection of metal surfaces and delivering substantial cost savings.
