IIReading the basis labels

What the basis labels mean

Operator engagement

Work done for an operator on a producing field: forecasts, reviews, plans and registers delivered into the operator's own systems and documents. The operator, the field and the facilities are not named.

Assos study

Study, concept or pre-FEED work prepared and issued by Assos Tech to a client under our own document control. The stage is stated. None of it is presented as a built or operating asset.

Practitioner experience

Experience of our senior people gained in previous employment, anonymised. Not an Assos Tech contract. Included to show the depth we bring, not as a company track record.
