CHEMICALS
If there is any one market that is showing an upward trend in terms of 
production, transactions, infrastructure and development, it is oil and gas 
industry. This sector plays a key role in deciding the fate of the world economy. 
This sector is accelerated by the uniform increase in drilling oil production, 
which is directly proportional to the demand for oilfield chemicals. 
Oil field chemicals are specialty formulations utilized in oilfields applications 
and drilling well sites. The efficiency and productivity of the oil field 
machineries and application areas depends on well site operations that cost-
effectively maximizes recovery of oil and gas reserves and minimizes the 
impact on the environment. Oil field chemicals impart unique capabilities and 
functionality to the operational sites for well drilling completion and 
intervention services. Oilfield chemicals majorly caters to three sub sectors, viz. 
Upstream, midstream and downstream
Since oil and gas industry involves huge investment in terms of capital, 
manpower and technology, smooth operations of every functional unit is 
always expected. It has been observed in recent times the increasing demand 
of easy and more convenient mechanisms for drilling and extracting 
applications. The rate at which oil field chemicals are taking over mechanical 
prospects proves about their conventionality as well as prudential performance 
on their utilization. Operating machines and mechanisms were subjected to 
their extreme points just for drilling application which would often lead to 
shortage of time for calibrating and adjusting the formulations in order to 
achieve optimal results. But using oilfield specialty chemicals under same 
limited resource has ensured maximum recovery of the crude products, 
increasing the working output and efficiency

  Let us look at the advantages of the using these chemicals:
 Improvement in the production at drilling sites and refinery processes
 Provides protection to metallic surfaces from highly corrosive agents that comes out during 
crude oil extraction, increasing their performance and longevity
 Nearly cent percent extraction of crude from the storage tanks which is usually prone to 
sludge formation at the bottom
 Using these specialty chemicals proves to be cost effective compared to maximum 
mechanical efforts
 Saves time and assures monetary benefits for the owners and stakeholders. 
OILFIELD CHEMICALS
 Oil field Upstream: Oil field chemicals, by its name can be understood as chemicals 
used in oilfields or oil well sites. These chemicals' efficiency and productivity depends 
on well site operations that cost-effectively maximizes recovery of oil and gas reserves 
and minimizes the  impact of the environment. Oil field chemicals impart unique 
capabilities and functionality for well drilling completion and intervention services. 
 Oil field Midstream: Another major part of oil and gas industries is midstream. This 
part involves the transportation of crude oil to various refineries through various oil 
channels, pipelines, oil-tankers etc.
 Oil field Downstream: Another major part of oil and gas industries is downstream. 
This part involves refining and purification of crude oil for end users applications 
through various processing and methods. The end use products that follows after 
refining / purification are petrol, diesel, kerosene, fuel, natural gases, LPG and different 
other types of petro-chemicals.
