Oil Field Services
Wireline Logging & Perforation
A wide range of logging solutions recording the precise downhole measurements required for formation evaluation, reservoir studies and wellbore diagnostics — with multiple conveyance options for safe, efficient operation in complex well trajectories.
Mission
To deliver superior value through high quality and high technology services, while being committed to business ethics and a sustainable environment.
Vision
To become the regional industry leading wireline service provider by keeping up high quality service, technology and solutions for our clients.
Established in 2010, validated in the field
Wireline is a division of the SeaLand Oil Field Services department. Operational planning, engineering and coordination take place at our Tehran and Ahwaz bases. Service delivery is carried out from Ahwaz for onshore fields and from Kish for offshore fields.
We proudly deliver sustainable, high-quality services to the National Iranian Oil Company and its subsidiaries — including NISOC, IOOC, POGC, NIOC Exploration and ICOFC. With experienced personnel across operations, technical and maintenance, Geomission, support and asset control, we continually enhance our service quality.
Our performance has been validated by over 1,200 successful operations and more than 100 appreciation letters received from clients over the past decade.

Applications
The questions a wireline run is there to answer.
Logging is not an end in itself. Every descent into the well is commissioned because someone has a decision to make, and the log is the evidence they make it on.
What is in the formation, and is it worth producing?
Resistivity and induction strings, imaging and sonic data give the porosity, saturation and lithology needed to decide whether a zone is a reservoir worth completing — and where its boundaries sit.
Is the cement doing its job?
Cement bond, segmented bond and radial bond logs show whether the annulus is sealed and where channels exist, before pressure is put on the well rather than after.
How much life is left in the casing?
Multi-finger imaging and circumferential borehole imaging quantify internal corrosion and deformation, turning integrity from an assumption into a measurement.
Which zone is actually producing?
Production logging separates the contribution of each interval, identifies water entry points and detects cross-flow during shut-in — the basis for any remedial decision.
Where exactly is the well going?
Gyro surveys give an independent, magnetically-uninfluenced trajectory, which matters most in cased hole and in close proximity to existing wells.
How do we get the reservoir to flow?
Perforation puts the flow path through casing and cement into the formation. Charge selection, shot density and conveyance are chosen against the completion, not applied generically.
Conveyance & delivery
Getting the tool to depth, whatever the trajectory.
Multiple conveyance options are available for safe and efficient operation in complex well trajectories — the reason a deviated or highly-inclined well is a planning problem rather than a barrier.
How we reach the target
- Standard electric line for vertical and lightly deviated wells
- Tubing conveyed perforation where the interval is long or the well is highly deviated
- Coiled tubing conveyance for extended-reach and live-well intervention
- Through-tubing tools for production services without pulling the completion
- Onshore delivery from Ahwaz; offshore delivery from Kish
- Offshore skids and logging trucks matched to the location and the service
