In order to overcome the mud build-up which is blocking the flow at Iacea Mica-1 (IMIC-1) gas well within the license, Australian ADX Energy, the operator of the Parta onshore license, said that it plans to launch acidization tests.
The statement from the company said that the aim of the 230,000 euros worth program is to initiate flow by overcoming expected well bore damage which has been interpreted as preventing material gas flow from the well by injecting acid into the reservoirs surrounding the well bore, determine reservoir fluid composition and the flow capacity of the reservoir. Operations will include coiled tubing for pumping acid into the well, nitrogen for lifting liquids from the well and surface testing equipment for separating, measuring and flaring produced gas and their duration will be approximately ten days after mobilization. The tests are scheduled for 7 September.
In July, UK-based Reabold Resources, ADX Energy’s partner in the project, said that IMIC-1 well at the Parta onshore perimeter in Romania is blocked and may require reservoir acidization to enhance flows. The mud filtrate build-up around the well bore has potentially occurred resulting in reservoir fluids being blocked due to mud ingress into the reservoir and the build-up of non-permeable filtrate from drilling mud. The damage can be overcome with acidization, which is a routine practice within these reservoirs in the Pannonian basin. In April, Reabold Resources said that it delayed the testing of its IMIC-1 well at the Parta license due to restrictions enforced by authorities because of the COVID-19 pandemic. Last September, Reabold Resources announced that it will increase its stake in Danube Petroleum to 41.6 from 37.5 % via a subscription for new ordinary shares. The remaining 58.4 % is held by Australian ADX Energy. The company made this decision in light of a recent discovery of oil and gas at Iecea Mica 1 appraisal well, within the Parta onshore perimeter in Romania. Previously, the two companies announced that they have found hydrocarbons within Iecea Mare onshore perimeter in Romania, after completing the drilling at the Iecea Mica-1 well. The statement from the companies said that the well is now being prepared for production testing. ADX Energy also said that said it now estimates 2C contingent resources of 20 billion cubic feet, up from a previous 6.1 billion.
