Titan's Ten-Step Process

STEP 1: Submit Reservoir Data

The first step is to submit the required petrophysical reservoir data to Titan. From that information Titan’s petroleum engineers will determine if the reservoir has the general favorable characteristics and potential for a successful enhanced oil recovery treatment.
The client should complete the Application for Complimentary Field Analysis Form as fully as possible. Titan’s petroleum engineers will review the data, and will need to contact the oil operator’s technical staff to clarify technical points. Field maps and other reservoir information will also be inspected. Typically we will be looking for data that suggests significant quantities of oil have been by-passed in the reservoir due to premature water channeling, poor sweep efficiency, or excessive amounts of irreducible oil trapped in the pore matrix. The mechanical suitability for the Titan Process stimulation will also be assessed and discussed. The best candidates are typically thick heterogeneous non-fractured reservoirs that produce oils in the 16 to 45-gravity range with high (75% - 99%) water cuts.

STEP 2: Fluid Samples Taken

If the petrophysical information appears favorable, step two is to collect representative fluid samples and send them to Titan’s microbiological laboratory for analysis.
Representative wellhead samples of the produced oil and water must first be obtained and sent to Titan’s laboratory. A Titan petroleum engineer will discuss the sampling process with the field personnel responsible for sampling. In some cases Titan may have a local representative catch the samples. The samples must be collected in an exact sequence and manner. This is relatively a simple step but attention needs to be paid to the details of the collection procedure. Samples must be delivered to the Titan labs within two days of collection.

STEP 3: Lab Analysis

The third step is Titan’s lab analysis to determine if a favorable microbial community exists in the reservoir, and for Titan to design a suitable nutrient stimulant for that specific community.
Once received in Titan’s Los Angeles laboratory, it typically takes about two weeks to six weeks to evaluate the microbiology of the reservoir. With this analysis complete it is then determined what would be a suitable designed nutrient stimulant. If an unsuitable microbiological community is detected or if a stimulant can’t be designed, the client is so notified and the process stops at this point.

STEP 4: Pilot Test Agreement

The fourth step is to enter a pilot test agreement with the field operator.
At this stage a formal pilot test agreement is entered on a best efforts basis between Titan and the field operator. All details of the Pilot and the schedule of the process, responsibilities and costs are agreed to.

STEP 5: Field Analysis

The fifth step is a field analysis to make sure equipment and other field data is known to Titan.
A field inspection and site visit by Titan personnel may be required if more than a one well test is desired. During this time a field pilot test will be planned as to which section or units of the field will be tested. In some cases multiple tests can be performed on different sections of a single reservoir, or multiple pilot tests can be accomplished simultaneously on adjacent reservoirs. Both the operator and Titan will plan the size and scope of the pilot test. Titan will submit a written plan for the operator’s approval.

STEP 6: Pilot Test Planned

This is usually a one well test to make sure the lab work and the actual field responses are in sync. The main purpose of the in-situ test is to make sure the microbial reactions in the reservoir under actual field conditions are the same as what was observed in the lab.

STEP 7: Monitoring Protocol Established

The seventh step is to establish the protocol and set up the pre-treatment monitoring system that will be required for a proper “before and after” evaluation of the success of the treatment.
The plan will also include a detailed monitoring protocol to insure an adequate “before and after” baseline study can be established. This would normally take 60 days. The plan may also provide for a chemical tracer test to discover inter-well communication patterns and reservoir residence periods for the injected nutrients. These tests are necessary to properly displace the nutrients throughout the targeted areas of the reservoir. The dual objectives are to provide accurate field data during this period, which will enable Titan to deliver the best treatment possible and then to define the changes in oil and water production attributable to the Titan Process. In some cases other field operations may be conducted simultaneously (drilling, re-completions and well stimulation work, etc.) which could mask the Titan Process results. The primary part of the plan will be to establish a well test schedule and any injection tests (step-rate and fall-off tests) needed.

STEP 8: Titan Process Starts

The eighth step is to deliver the nutrient stimulants to the reservoir and follow the injection protocol and schedule.

In most cases a single production well test will take 5-8 hours for the application of the Titan Process. In some cases, a pre-treatment may be needed two weeks prior to the initial Titan Process stimulation. The pre-treatment could take 1-2 days and 1-2 weeks of observation. Titan personnel will conduct the pre-treatment in the same manner as the Titan Process treatment. The initial Titan Process treatment step (after a pre-treatment if needed) for an injection well will take between 1-3 days depending upon the size and scope of the injection well pilot test. The Titan Process should use repeat injections over the course of 4-6 months depending on specific field characteristics.

Delivering the Titan Process nutrient stimulants to the reservoir will vary on a case-by-case basis, and the costs will be higher for remote, foreign and offshore locations. In every case it will be necessary for the operator to provide access to the target injection well bores and suitable mixing and pumping facilities to inject the treatments into the target wells.

In most cases existing field facilities can be used, in others a rental pump or pump truck may be needed along with a 100 to 200 bbl mixing tank. Titan personnel will be on location to administer the treatment. The scope of this step will depend upon on variables such as the number of production and injector wells, volume of fluids, and the size of and number of treatments.

STEP 9: Monitoring and Additional Treatments

Step nine is monitoring the results and administering subsequent treatments as dictated by the reservoir response.
After the initial Titan Process treatment is injected, stimulation is now in progress, and samples will be caught on a regular basis and sent to the Titan laboratories on a weekly or bi-weekly basis for analysis. Based upon that analysis, subsequent treatments may need to be performed. Possibly another treatment should be anticipated during the first six months following the initial treatment. Each of these subsequent treatments will be administered in a fashion similar to the initial treatment.

STEP 10: Evaluation and Analysis

Step ten is the evaluation and analysis of the pilot test.
This requires field personnel to monitor the oil production and other well characteristics. If the results are satisfactory and meet the requirements of the operator, then a larger field deployment can be planned as well as other field pilot tests and implementations.
