De-Risk a Refrac in One Scan

Completely understand your well by evaluating it in 3D to confidently plan next steps.

Check every component and casing joint for breaches, deformation, wall loss, and issues that can compromise well integrity. Catch issues before they affect the profitability of your refrac operation.

Determine exactly how much pressure a well can handle in its current condition with industry-leading calculation methods

Measure where proppant went in the initial hydraulic fracture and figure out where new proppant should be placed by measuring perforation erosion.

Well Integrity Inspection

Avoid costly workovers or the loss of the well from unforeseen issues by performing a well integrity analysis prior to refracture. Operators are ensuring aging components are fit-for-service and understanding the extent of any damage or defects that may have occurred in the lifetime of the well.

Casing Connections

Identify joints and connections that may fail at lower pressures. Evaluate joints that are over-torqued, improperly connected, have damaged threads, or are in a compromised state that may fail at higher pressures.

ID and OD Corrosion

Ensure liner hangers and packers are set and properly seal at locations free from corrosion, pitting, and ovality by evaluating and differentiating wall loss on the ID and OD of casing at submillimetric resolution.

Mechanical Damage

Verify the quality of workover operations and component installations. Check and measure any damage that may have occurred and ensure components are in the condition and position as expected.

Ovality

Don’t get surprised by smaller than expected pass through diameters. Measure changes in ovality, minimum diameter, and casing deformations that can occur from geological forces or fracs.

Advanced Burst Pressure Analysis

Unlock enhanced calculation methods as defined by ASME B31G with direct submillimetric 3D measurements of wall loss. Advanced methods determine more representative estimates of the maximum pressure a section can handle – meaning operators are able to refrac more effectively with higher pressure.

Barlow: Provides a conservative estimate of max pressure by assuming the max defect depth continues across the entire joint length and is the only option when wall loss measurements are not high enough resolution.

Modified B31G: Provides a conservative estimate of max pressure that starts to factor in defect wall loss length but assumes a simplified depth profile based on empirical correlation and assumes measurements don’t capture the full wall loss depth profile.

Effective Area: Provides a more representative estimate of max pressure by factoring the full depth profile of the wall loss of the defect and requires high-resolution thickness measurements. Handles complex and interacting defects and geometries much better.

Stimulation Effectiveness Analysis

Maximize recovery rates, improve operational efficiency, and identify plug damage with the most comprehensive perforation erosion evaluation. Inform and validate fracing strategies before and after a refrac or recompletion with acoustic imaging that delivers actionable insights into stimulation effectiveness and proppant distribution.

Clearly understand where proppant has gone by measuring the erosional growth of each perforation in 3D at submillimetric resolution.

An Optimized Refrac in Eagle Ford

An operator turned to DarkVision to perform a well integrity and burst pressure analysis to assess the potential of refracturing a well without a frac string.

Process

DarkVision’s high-resolution measurements of an identified defect meant the operator was able to use an Effective Area calculation to get the most representative estimate of max pressure over the affected area. This Effective Area calculation revealed a threshold of 11,954 psi whereas a Barlow, a less representative method, estimated a much lower burst pressure of 5716 psi.

Outcome

Based on the detailed report from DarkVision, the operator evaluated every defect and the maximum safe re-frac pressure and determined a re-frac string was not needed. This led the operator to confidently proceed with a re-frac and safely operate 6,000psi higher across this joint without compromising the integrity of the well.
