ENZYMES
ZENITH ENERGY ENGINEERING Zenith Energy Engineering is a division of the Zenith Energy group It is an enzyme based company that deploys a unique enzyme based
technology It provides a safe, efficient, and cost-effective environmental services to
our clients . Our services include 1. OIL FACILITY CLEANING(storage tank and pipeline)2. OIL SPILL RESPONSE AND BIO-REMEDIATION3. EFFLUENT AND WASTE WATER TREATMENT4. OIL WELL RESTORATION At Zenith Energy Engineering Ltd , the interest of our client is our
topmost priority. We believe that our success in business depends largely on our clients
satisfaction from our services. As a policy, we deploy or utilize highly efficient enzyme- based
technology in all our services in order to provide quality, safe and cost-effective results to the satisfaction of our clients.
OIL WELL RESTORATION SERVICES
Under oil well restoration services, we treat the following substances….
1. Wax.2. Asphalthene wax3. Scales4. Paraffin wax
HOW OUR ENZYME BASED TECHNOLOGY WORKS
1. In order to guarantee excellent results, our enzymes perform these key functions by preventing wax from
Reducing reservoir productivityPlugging perforationsPlugging down hole pump intakesPlugging tubing?Increasing stress and wear on rodsCausing holes in tubes

1. In order to guarantee excellent results, our enzymes perform these key functions by preventing wax from

intakes Plugging tubing? Increasing stress and wear on
rods Causing holes in tubes
Plugging flow lines.Causing flow lines leaks.Causing separation problems.Generating tank bottoms sludge.
HOW WE WORK(MODUS OPERANDI)
• We first ensure that a tool-box meeting is held to shut down the well after reporting to site and obtaining a permit to work(PTW).We carry out the operation by
Performing a site survey and analysis which includes procedures of working, layout of pipes, reservoirs and getting samples from each well to determine its constitution.
Carry out a wax mapping i.e. depth of it in each well with the client.??
Prepare the RAP(Remediate action plan)Submit RAP for approval.Get approval for RAP.Prepare the budget.Get approval for the budget.Prepare the work plan.Mobilize to site enzyme, men,
equipment ,holding tank and mix the enzyme solution
Shut the well down systematically after the tool-box meeting.
Inspect the shutting down.
Inject the solution ,ensuring 20psi more than the internal pressure pump.
Allow to soak for about 5 to 7 hours.Connect the well back and monitor to
evaluate(the flow rate, the,, composition of the crude, the physical and chemical characteristics)?
Monitor the actual reduction in sludge,wax and the increase in production.
Close the site by re-opening the well.Submit all report duly signed to obtain a work
completion certificate(WCC) in collaboration with the client.
STEPS FOR TREATMENT
Get pumps of the right pressure.Pump crude from the well into the holding tank. Inject the enzyme formulation and allow it to mix in the
holding tank.Pump the solution from the holding tank into the well
and allow it to soak for 5 to 7 hours.Couple the well back.Repeat every 3 to 6 months. While treating ,ensure
that well is shut down, check whether the de-sander is faulty and change if so.
RESULTS OF OUR EFFICIENT ENZYME OPERATIONS
1. In order to guarantee excellent results, our enzymes performs these key functions by preventing paraffin from
Reducing reservoir productivity
Plugging perforationsPlugging down hole pump
intakesPlugging tubing Increasing stress and wear on
rodsCausing holes in tubes
RESULT OF OUR EXCELLENT ENZYME OPERATION
Plugging flow lines.Causing flow lines leaks.Causing separation
problems.Generating tank bottoms.2.Asphaltene removal and
reduction has shown production of crude that exhibits higher purity in both chemical and physical appearance
RESULTS OF OUR EXCELLENT ENZYME OPERATIONS
2. The procedure is done without crude oil recovery and this increases profit as the cost of production is reduced.
3. The procedure ensures a continuous treatment which last for a long time and this reduces the cost of production.
