Well Completion
Well Completion & Intervention Services
Maximising well productivity through expertly executed completion and intervention programmes — from initial completion design to coil tubing and wireline operations.

Service Overview
Comprehensive Well Completion & Intervention
Sequential International delivers fully integrated well completion and intervention services for both new and existing wells. Our competent team handles completion string design, perforation, stimulation, and all categories of well intervention.
From simple plug-and-abandon operations to complex multi-stage stimulation jobs, we combine technical depth with field discipline to maximise well productivity and extend producing life.
“Every well we complete or intervene on is treated as a long-term production asset — we do it right the first time.”
What We Deliver
Scope of Work
Well Completion Design
Selection and installation of completion strings, tubing, packers, and downhole equipment optimised for reservoir conditions.
Coil Tubing Operations
Cleanout, stimulation, logging, and intervention using coil tubing units across a range of well configurations.
Slickline Services
Plug-setting, gauge installation, choke changes, and downhole diagnostics using slickline units.
E-Line / Wireline
Electrical wireline logging, perforation, and completion diagnostics for formation evaluation and well management.
Sand Control
Gravel pack and frac-pack completion systems to control sand production in unconsolidated formations.
Stimulation
Acid stimulation and matrix treatments to restore or enhance well inflow performance.
How We Work
Our Service Process
Well Data Review
Analysis of completion design, reservoir data, and intervention objectives.
Programme Design
Detailed well intervention programme with risk assessment and contingency planning.
Equipment Rigging
Rig-up of coil tubing / slickline / wireline units with full pressure control verification.
Execution & Post-Job
Controlled execution with real-time data acquisition and comprehensive post-job reporting.
Why Choose Us
Key Benefits
Maximised Well Productivity
Optimal completion design and execution delivers better inflow performance and production rates.
Reduced Intervention Frequency
Quality completions minimise the need for repeated costly well interventions.
Real-Time Data
E-line and slickline tools provide critical downhole data to inform reservoir management decisions.
Single-Source Provider
Completion and intervention under one roof reduces coordination risk and mobilisation cost.
Sand & Scale Management
Proactive completion design addresses common production impairment challenges.
24/7 Capability
Round-the-clock operations support for time-sensitive completion programmes.
All coil tubing and wireline operations are conducted under a formal well control safety framework. Barrier verification, pressure test records, and crew well control certifications are mandatory before every job.
