Aker Solutions :: Wireline services

Wireline winch

Well Intervention by means of Wireline is a cost efficient method of reaching operational objectives. The tools and equipment are conveyed into wells either through an "open hole" without surface pressure, or through special pressure retaining equipment which allows the toolstrings to be conveyed into live wells with full production pressure.

Wireline Services encompass slick, braided and electric line, plus specialised services such as H2S service and heavy-duty units for fishing. Typical operational objectives are:

Mechanical operations: setting plugs
Well clean up: removal of sand or debris
Explosive services: punching or perforation
Data acquisition: production logging

In accordance with the increasing use of subsea technology as a field development solution, Aker Solution has performed extensive engineering, enabling our Well Intervention Services to be supplied cost effectively from light intervention vessels.

Wireline operation

The above picture shows a typical Wireline rig-up offshore. There is a valve tree under each of the hatches on the hatch deck. The valve tree is Aker Solution's physical borderline with the customer's platform. All the equipment seen on the hatch deck is used for the objective of conveying tools and logging equipment in a safe and efficient way to their target depths in the well.

Preparing to convey perforation guns

The above picture shows a Wireline operator as he guides perforation guns into the Wireline riser. The work is physically demanding and requires a rigour HSE-mindset.

The quality systems for all operations are accredited and certified to the ISO 9001:2000 standard.
