FAQ

Choosing a service line

Which service should I start with?

Mechanical work such as plugs and valve maintenance usually starts with slickline. Logging, perforating and pipe recovery sit with wireline. Cleanouts, nitrogen lifting, milling and fishing are coiled tubing work. Chemical treatments use pumping and stimulation.

Can several services run as one campaign?

Yes. Integrated well intervention sequences slickline, wireline, coiled tubing and pumping under one Heinz-oil team so interfaces stay with a single point of accountability.

Do you rent surface equipment without a full crew?

Rental and conveyance covers tanks, batch mixers, compressors, generators, scaffolding and downhole tools. Crews can be added when the scope needs them.
