HIS
OIL RECOVERY/FLUID ENHANCER
HIS
OIL RECOVERY/FLUID ENHANCER is a unique
blend of polymers within a proprietary solvent solution.
The ability to have reacted the components together makes the
product a 100% active product rather than a diluted compound.
Chemex has found two unique applications for this product.
Both involve increasing oil production from producing wells thereby
increasing operators’ profits.
The
first method involves stimulating oil wells by squeezing the wells with
the HIS OIL RECOVERY/FLUID
ENHANCER.
After a through evaluation of the wells, or field, a recommendation
can be made for chemical application.
An
animation of one application can be seen by selecting this link.
In
testing of producing stripper wells in East and West
Texas, production from the wells increased
from 5 barrels per day of oil to 14 barrels per day of oil.
An
increase in 
production to 10 barrels per day of oil has been observed for six months
and longer. In testing in
Venezuela, in higher production
wells, we have seen an increase in oil production from 104 barrels per
day to 330 barrels per day.
An
increase in oil production has been seen in all tests accompanied by
a total fluid volume increase with a lowering of BS & W.
HIS
OIL RECOVERY/FLUID ENHANCER
can also lower the viscosity of heavy crudes.
Laboratory testing has shown that when HIS OIL RECOVERY/FLUID
ENHANCER is added directly to the heavy crude,
viscosity is reduced.
With
the reduction in viscosity, more oil should be produced.
In
Venezuela,
a high API gravity diluent
was added down the casing in order to facilitate the removal of crude
and to increase the production.
HIS
OIL RECOVERY/FLUID ENHANCER
added to this high API gravity diluent in Venezuela has resulted in
lower crude oil viscosity, reduced pressure at the wellhead, and an
increase in production.
HIS-WD is
a blend of polymers and solvents usedto increase flow from medium to
heavy crude oil production. HIS-WD lowers viscosity of highly viscous
crudes which lowers working pressures in both production tubulars and
pipelines. HIS-WD has been used to stimulate and increase production
in older oil wells. HIS-WD can be used to decrease the amount of light
crude diluent needed to improve the pumpability of heavy crude. A

SPEEDFLOW
SPEEDFLOW
is a field proven
drag reducer for use in crude oil pipelines.
SPEEDFLOW
has been used in the industry in lower API gravity oils as well as commodity
fuels.
SPEEDFLOW
is a long chain polymer used for reducing drag in crude oil pipelines
for low enhancement and improvement.
The long chain co-polymers usually reduce drag by 
changing a turbulent flow in the pipeline to a laminar flow thereby
reducing pressure and allowing increased flow throughput.
Drag
reducers have a history of not only increasing the flow throughput of
the crude oil but of also reducing the fuel consumption of the crude
oil pumps.
All of these advantages are a must in these ever changing days
of the oil industry.
SPEEDFLOW
has received EPA approval for use as a diesel fuel additive.
OTHER
COMMONLY USED PRODUCTS SUPPLIED TO THE OIL FIELD
DEMULSIFIERS
Demulsifiers
have had a long history of involvement with reducing water content in
the emulsified crude or processed oil.
Their main use is to dehydrate oil.
Not only must they dehydrate oil but they must also de-oil the
water. Water quality has
become as important as oil quality.
Therefore, demulsifiers must not only dehydrate oil, drop water,
but it must maintain clean, effluent water.
CORROSION
INHIBITORS
Corrosion
inhibitors are usually of three main types, oil soluble, water soluble
or oil and water dispersible. These
products usually inhibit the destructive attack of a metal by a chemical
or an electrochemical reaction.
SCALE
INHIBITORS
Scale inhibitors as their name implies stops or inhibits the formation
of scale in oil and water pipelines.
Scale inhibitors are categorized into three major chemical families,
phosphate esters, polyacrylates and polyphosphonates.
The three most common types of scale in the oil industry are
calcium carbonate, calcium sulfate and barium sulfate.
Once scale has
deposited it may be virtually impossible to remove without mechanical
means or acid job so it is imperative to prevent the deposition of scale.
PARAFFIN
INHIBITORS
There
are basically three main types of paraffin products used to suppress
or eliminate paraffin buildup: these include solvents, dispersants and
inhibitor/pour-point depressants.  Solvents
are strictly used to dissolve already formed paraffin.
Inhibitors are used to eliminate the forming of the paraffin
molecules before the cloud point.
The cloud point is
the temperature where the paraffin molecule has begun to form.
After any paraffin has formed then the addition of a dispersant
would be used to keep the paraffin in solution.
WATER
CLARIFIERS
A water clarifiers’ ultimate goal is to clarify water by de-oiling produced
effluent water for proper disposal.
Not only do these products assist in meeting legal requirements
for disposal, which is everyone’s primary concern, it also allows for
retrieving the oil in the effluent stream, thereby increasing profits
and reducing problems.
Water clarifiers are composed of three primary categories: metal salts,
polymers and blends of these two products.
The primary purpose of these chemicals is in assisting the separation
of oil and oily dispersed solids from water.
Demulsification
and water clarification goes hand in hand, and in many cases requires
on-site development.
