In well construction, many cost-saving measures never appear on a service invoice. When teams prevent cementing issues before execution, they help reduce nonproductive time (NPT), protect well integrity, and keep projects on schedule.
Strong service quality practices based on defined control points support these outcomes. For operators and procurement teams that evaluate total cost of ownership (TCO), prevention can deliver significant value.
Between January 2025 and June 2026, Halliburton cementing teams in Latin America applied more than 1,400 proactive quality interventions to optimize job execution and reduce operational risk. These actions helped prevent an estimated 1,808 hours of nonproductive time and nearly $4.5 million in potential cost of poor quality (COPQ).
Although the estimates do not represent guaranteed outcomes, the results demonstrate the value of a disciplined quality process. The data identifies recurring operational risk indicators and shows how early action can improve execution, maintain service quality, and reduce costs.
What triggered the interventions?
Four primary intervention trigger categories recurred consistently throughout the Latin America data.
Deviations to approved design of service: Last-minute design of service (DOS) changes without engineering review
Late-stage DOS revisions introduce risk when teams bypass engineering review and weaken fluid and procedure quality controls. Without formal verification, crews may execute a job with slurry designs, placement parameters, or equipment configurations that do not reflect actual well conditions.
Function test per Job Site Quality Assurance: Unprepared third-party equipment
Interventions occurred when third-party equipment arrived at the wellsite without adequate preparation for the cementing operation. Although this issue occurs before cement placement, it can affect execution quality through pump scheduling, fluid compatibility issues, and mechanical performance challenges.
Well condition validation per job packet: Pump pressure conditions that differ from the plan
Pressure conditions that differ from design assumptions can compromise cement placement. Pressure spikes may fracture the formation or prevent complete displacement, which leaves cement in the casing. Pressure losses may result in an inadequate top of cement that fails to cover the zones of interest. These outcomes can compromise zonal isolation and increase remediation risk.
5 checks to go as per Job Site Quality Assurance: Execution that deviates from design intent
Changes in personnel, equipment, or procedures can shift execution away from the approved design. These deviations often remain unnoticed until placement begins.
Require engineering review for significant DOS changes
A formal review process with the appropriate technical reviewers and decision makers helps verify that revised slurry designs, pump schedules, and well parameters continue to meet job objectives. Engineering sign-off should remain a requirement for significant DOS revisions before field execution.
Establish a receiving standard for third-party equipment
When cement job execution depends on third-party equipment, readiness must be verified before the job begins. Operators that establish clear receiving and preparation requirements for third-party equipment can reduce a recurring source of NPT risk.
Strengthen technical verification
The ability to identify abnormal pressure conditions during verification often depends on the expertise and authority of the reviewer. Personnel who understand the engineering basis of the DOS can identify pressure anomalies before they affect job execution. Effective verification requires technical knowledge and engineering judgment, not task completion alone.
Formalize change management
Changes to personnel, equipment, or procedures can create gaps between design approval and field execution. These gaps increase the likelihood of interventions, NPT, and well integrity issues. Establish a deviation management process that requires engineering review and re-verification before field teams implement significant deviations. Define which deviations require review, identify approval authority, and specify the documentation required before execution resumes.
The four primary intervention trigger categories identified in Latin America operations are not unique to that region. They reflect common challenges in pre-job coordination, verification, and communication in complex well construction operations.
Procurement teams that evaluate cementing providers primarily on price can overlook important contributors to total well cost. Costs associated with remedial work, well integrity issues, and production delays often occur later in the project lifecycle rather than on the original service invoice. As a result, the total cost associated with a pre-job deviation may not be immediately apparent.
COPQ from preventable cementing failures often remains unattributed because the deviation and the resulting failure are recorded in different systems and stages of the well lifecycle. Field teams may record an intervention event in one system while well integrity teams document sustained casing pressure in another. Without linking those records, the full cost of the failure may not inform future service evaluations.
Execution price is only one component of cementing value. Risk identification, verification, and quality control can influence whether a job delivers the intended design or requires costly remediation. The Latin America data raises additional questions for operators and procurement teams:
Those factors may not appear in a price comparison, but they can influence total well cost. A procurement strategy that incorporates key control points, prevention, verification, and execution quality provides a more complete view of cementing value and long-term well performance.
