Abstract

A method of cleaning production tubing in a producing petroleum well comprising the steps: i) providing collection tool configured for both selectively collecting debris while residing downhole to obtain collected debris as well as selectively releasing collected debris while residing downhole; ii) lowering collection tool to specific location at certain depth into production tubing of the producing petroleum well where there is at least a partial choking of local production flow due to accumulated debris deposited on production tubing; iii) collecting accumulated debris with collection tool to obtain collected debris; iv) pulling collection tool to production zone of production tubing or downstream of production zone where there will be enough production flow during production to ensure lifting capacity for collected debris; and v) releasing collected debris into production zone of production tubing to obtain released debris being lifted by production flow when production is running. The invention leads to time and cost savings during cleaning of production tubing.
