Abstract

Matrix acidizing of satellite wells in deepwater fields depends on the use of a dynamic position vessel (DPV), what makes it a very expensive operation. Moreover, the availability of DPVs for stimulation treatments can be a limiting factor for deep water and even for ultradeep water fields. For some shallow water fields with particular characteristics, the use of DPVs is also mandatory. While the acid treatments of several satellite wells in the Campos Basin, offshore Brazil, are not performed due to cost restrictions and/or DPV availability, injectivities and productivities of those wells are decreasing. If not properly controlled, these declines could jeopardize the profitability of some fields. One solution for this problem, devised by Petrobras R&D Center (CENPES), consists of anchoring the stimulation boat to the production rig and pumping the acid treatment through the flexible pipelines, which may extend for several kilometers. The main difficulty for performing such a treatment is controlling the corrosion of metallic parts of the pipelines, as well of the Christmas tree and tubing. This paper presents the results of the remote acidizing of an offshore well of the Campos Basin, producing oil from a carbonate reservoir. The paper also describes in detail the laboratory tests required for the field test.
