Frequently Asked Questions

Q: What is Tracermax technology?

A: Tracermax technology can be used in the following subsurface tracing applications:

1. The presence of light weight cement slurries (<1500 kg/m3) behind well casing.

2. The height of cement “squeezes” for remedial intervention .

3. The placement of fluids used for hydraulic fracturing operations .

4. Production logging.

5. Fluid Identification .

6. Tagging downhole jewelry such as float shoes, collars, etc.

Q: What is the Tracermax advantage?

A: Tracermax tracer products replace the use of dangerous open source radioactive materials. The use of Tracermax tracers gives many advantages as follows:

1. All aspects of Tracermax technology give low level detectability for definitive information.

2. Borated tracers and Cadmium based markers are non-contaminating, user friendly and are not considered dangerous goods for purposes of transport.

3. The neutron activation of Boron or Cadmium do not render any long lived radioisotopes

4. Tracers can be shipped a global basis by any mode of transport without specialized packaging, or DG manifestation.

5. No special licensing required for possession or handling of tracer chemicals

6. No site decommissioning, monitoring or tank rentals to retain contaminated well flow back production

7. Most oil service providers offer neutron logging services

8. Wells tagged with Tracermax insitu tracers can be logged over extended period of time.


Q: Why use Tracermax to trace oil well cement?

A: The most important reason to use Tracermax tracers in oil well cement is to prove radial hydraulic isolation for both pressure control and the containment of petroleum reservoirs from seeping up hole through micro annulus (gas vent flow), channels or voids. These conditions are created by the improper cementing of decentralized positioning of well casing or lost circulation zones By tagging the cement in surface (conductor) and intermediate casing string(s). The use of Tracermax tracers can detect lightweight or nitrified slurries below the detectable limits (<1500 kg/m3) and minimum threshold of current sonic applications (CBL). Radial well bore imaging using Tracermax tracers can logged using specialized Neutron/multispectral Gamma well logging tools.

1. The addition of Boron Carbide will not adversely affect the physical integrity or properties to oil cement slurries

2. Boron Carbide can be mixed or blended directly into cement powders eliminating tracer addition at the field operations level .

3. Tracermax tagged cement slurries can be logged immediately before setting times (36 hours) eliminating rig and costly stand by time

4. Tracermax tracers are most beneficial for offshore wells to insure containment of hydrocarbons from leaking into ecologically sensitive maritime environments

 

Q: Why use Tracermax for hydraulic fracturing operations?

A: Boron Carbide tracer can be used to trace fracturing stimulations with respect to the placement of proppants. This allows for the calibration of the frac height window essential for growth propagation modeling. Boron carbide is a ceramic that is chemically inert and will not react with frac fluids or interfere with the cross linking or breaking of water or oil based polymer gel propellants. Boron Carbide is compatible with sintered Bauxite or Alumina proppants under tested conditions.

Tagged fracturing fluid additives can be traced for identification purposes with respect to communication into wastewater systems from an environmental and occupational protection perspective.

The well log shown below is an example of frac height definition using Tracermax tracers. The data track on the right hand side shows frac height against the perforated interval (shown as the vertical black bar on the left side of the log).……



Q: Why use Tracermax tracers for production logging?

A: Tracermax production logging applications for precision measurements include:

1. Tracer ejection tools can be used to eject tracer compounds in zonally isolated intervals in either disposal or production wells for corrosion studies for casing integrity.

2. Tracermax tracers are non-contaminating and can be used in production wells. Fluid velocity measurements for determination of slow moving fluid velocities( < 4 feet/sec.) from selected perforations. No minimum threshold velocity back calculation required such as spinner technologies.

3. Tracer compounds are designed to match well bore fluids and are available in water soluble, oil miscible or gas tracer forms. Special requirement tracer compounds can be synthesized for specific applications.

4. Enriched Borated tracers can be used for increased low level detectability for enhanced performance.

5. Tracer compounds are compatible with multiphase fluid environments.

6. Tracer compounds can be used for inter well tracer studies or tagged fluid identification from producing wells after production stimulations such as acidizing treatments .

Q: Why use Tracermax marker tags?

A: Tracermax marker tags are non-dispersible and come in either Cadmium metal or Borated chemical forms. Tracermax markers are permanent and can identify the depth position of down hole jewelry for years. The markers are non-contaminating and do not require special licensing for handling or consideration when tagged components end up in scrap bins at well abandonment. Radioactive markers can be detected with radiation monitoring systems used to screen incoming shipments of scrap at metal recycling facilities. This leads to remedial actions are both labor intensive and expensive to isolate and recover radioactive tagged components for proper disposal.

Tracermax markers are contained inside thread flights giving positive placement of tagged component, as well as, preventing contact with well bore fluids. Tracermax markers can be used to position sub collars in tubing conveyed perforating (TCP) operations or float shoes and collars to prove total depth (TD) in well completions operations. Markers or marker compounds (Boron Nitride) can be used in the place of pipe thread lubricants.
