Magnetic Thickness Tool  

Qualitative analysis provides operators with data more detailed than traditional multi-arm caliper readings.

Electro-Magnetic Inspection Tool operation is based upon electromagnetic phenomenon from a coil arrangement inside of conductive pipe, measuring the different phase shifts in the electromagnetic field based on eddy current. The tool provides qualitative analysis of external metal-mass variations of the pipe, using proportional wall-thickness as a standard, that cannot be seen internally from multi-arm caliper readings. The resulting casing wall thickness provides operators with a better look at overall casing health.  

  • Can be run in conjunction with the multi-arm caliper to provide highly-detailed well analysis. 
  • Renegade offers two-sector and four-sector tools for better coverage.  
  • An eight-segment tool is available upon request.

Multi Sensor Caliper

The Multi Sensor Caliper measures highly accurate internal diameters, and can detect casing conditions such as deformation, bending, fractures, holes, and inner wall corrosion.

The Multi Sensor Caliper measures internal diameters with very-high accuracy, typically with less than a 0.03-inch variance. It will detect very small changes in internal surface conditions such as casing deformation, bending, fractures, holes, and inner wall corrosion. Calipers can provide highly quantitative analysis including an accurate and detailed internal profile of the tubing, casing and completion assembly. 

A multi-finger caliper log of the inside pipe enables operators to cost effectively plan work-over and remedial operations, and to keep historical records of the general condition of tubing and casing to assess any problems associated with corrosion, wear or mechanical deformation through the life of the well. 

Calipers are available in 24-, 40-, 56- and 60-arm configurations and can log a wide range of sizes from 1-11/16-in. ID tubing to 20-in. ID casing. The state-of-the-art, sophisticated logging tool performs an accurate inspection of the casing interior to determine casing condition and if the casing has sustained damage.

Radial Cement Bond Log 

Accurate information of cement channeling behind casing

The radial cement bond tool utilizes a single ceramic transmitter, an eight-segment receiver at 3-ft spacing and a single receiver at 5-ft spacing to accurately measure the quality of the cement job in a cased hole well environment. The segmented receiver provides a good indication of cement channeling behind the casing.  

This cement bond tool consists of oil-filled, pressure-compensated transmitter and receiver sections. The transmitter and both receivers are ceramic to withstand the hostile high temperature of well environments. Upon each transmitter firing, data from all the receivers is digitized and stored in internal memory, then sequentially transmitted to the surface. 

The digital signal section is capable of transmitting data to the surface from tools run below the RCBL such as gamma ray, casing collar log (CCL), in-line neutron, compensated neutron or other tools with one or two pulse channels. 

Transmission of the sonic data to the surface is accomplished by an internal controller which transmits eight to sixteen signals from radial receivers/sectors, a composite 3-ft signal (sum of all eight radial signals), a 5-ft receiver signal, and an internally generated calibration signal. Transmission of the remaining signals consists of digitally encoded data transmitted after the acoustic signals.

Injection Profile Logging (IPL)

Fluid Flow Data From Injection Wells Provide Insight on Overall Well Construction Integrity

As a field matures the need for injection profile data from injection wells increases. Running injection profiles eliminates assumptions of fluid direction providing an overall view of well performance and integrity, allowing operators to map their water or CO2 flood.  

Renegade Injection Profile Logging (IPL) checks the integrity of overall well construction on injection wells. Profiles are run to determine the health of injector units, monitor fluid dispersion, find and measure out-of-zone losses and provide a comprehensive picture of the overall downhole activity on an injector. This service can identify leaks out of the zones’ injection area, including packer leaks and holes in tubing where there are no perforations.

The shut-in portion of the injection profile log can provide customers insight into areas of fluid storage and communications between high- and low-pressure zones. Renegade’s injection profiles provide the confidence to efficiently tackle problem-well situations that can commonly cost much more and take longer to complete. Services are typically run every four years for water wells and two years for CO2 wells. 

IPL has two advantages over traditional mechanical services such as spinner tools. First, it can observe fluid movement behind pipe; second, they eliminate the risk of blades sticking if wellbore debris is encountered. In some instances, RA tracers may be the only way to identify and locate problem areas in the well. Renegade utilizes innovative equipment and tools and has an in-house RA lab to mix RA material for specific volume and job needs.

Production Logging Services 

Critical Data to Help Maintain Well Performance

Production Logging services evaluate fluid production rate and flow in producing wells and are a main indicator of well performance and problem identification. The results of a production logging services help recommend remedial treatment or workover operations.  

Renegade Production Profile Logging has proven to be the most reliable logging technique to give operators qualitative and quantitative evaluation of injection fluids and to aid in the evaluation of the performance of field floods.  

The same technique can be reversed for producing wells. Radioactive tracer surveys ran in conjunction with other surveys, such as temperature gradient, capacitance, velocity, bottom-hole pressure, fluid density and calipers, will give the operator a full complement of surveying techniques to help fully evaluate their wells.  

Applications 

  • Locate oil, gas and water entry 
  • Fluid flow: no-flow check and cross-flow check 
  • Shut-in cross-flow check 
  • Injection profile log: pump-in tracer, channel-down check and CO2 composite 
» Renegade designs the optimum production logging job with the right tools and equipment.

While many companies may provide this service, only Renegade has the knowledge to perform a successful job every time. 

Renegade Services has several production logging supervisors with over 25 years’ experience running production logging services. Our team will work with the operator to help ensure a safe, successful job, completed in the least amount of time.  

  • Select the right tools and equipment 
  • Make sure pressure control equipment is on location 
  • Review all well conditions such as temperature and pressure 
  • Weight bars and backup tools are available if needed 
  • Selection of radioactive isotope 
  • Safe operating procedures for handling and storage of radioactive materials  
Step-Rate Tests

Obtaining data is the key to planning a successful frac job. Step-Rate tests are one method for estimating the maximum injection pressure, one of the most useful parameters when planning the optimum frac treatment.  

A step rate test can accurately measure the injection pressure needed to fracture a formation when planning a hydraulic frac job. During the test, fluid is injected into the formation at increasing pump rates. As each rate stabilizes, injection pressure data is taken for each rate. The resulting data is used to create a plot displaying injection pressure verse injection rate. From this plot, pressure and flow rates can be established to identify the fracture pressure necessary to fracture the formation and successfully place fluid and proppant.  

Spectral Noise/Digital Temperature Survey

The relationship between reservoir flow and wellbore flow is critical to well performance. The Renegade spectral noise log in conjunction with a high-precision digital temperature survey can accurately locate and quantify reservoir flow and wellbore flow to help determine the relation between the two.   

This combination can diagnose unexpected well problems and also proactively ensure the well is working properly. Resulting data provides a wealth of information on well performance and can help identify zones where remediation is needed.  

  • Identify surface casing vent flow (SCVF) 
  • Identify external gas migration (GM)  
  • Identify fluid flow behind multiple casing pipe barriers 
  • Locate source of downhole leaks 
  • Help identify leaking fluids into freshwater reservoirs  
  • Identify regional lateral flows and crossflows 
  • Differentiate fluid and gas flow and amount 
  • Identify annulus leaks for sealing with Renegade Local Expander technology so P&A can commence

Renegade can use bond logs and casing inspection logs to identify, map and further explain spectral noise/digital temperature survey data.  

Renegade Memory Gauges

A producing wellbore creates a tremendous amount of information that must be gathered, managed and then interpreted. A variety of diagnostic tools can help you manage the production of your well and gain valuable insights into the processes that are occurring downhole. These tools provide the data that help operators to identify what systems to use to increase or maintain production and how to adapt to changing conditions of the wellbore. 

Memory gauges are one of the most helpful tools for well diagnostics. They detect and measure temperature and pressure at points along the wellbore. These gauges are beneficial because they provide downhole information without requiring substantial resources.

They also eliminate the need for deploying e-line each time temperature and pressure measurements are required.  Memory gauges are powered by a battery pack and can be set downhole and left for an extended period to capture and store data and then be retrieved at a later date. 

  • Data can be used to determine the flow rate of the well 
  • Provide information to help implement the right lift systems to maintain production  
  • Help devise a cost-effective and timely program to monitor and maintain the well production
