Inflow (Negative) Testing – Why & how?


When drilling the well and running tubulars, the drilling fluid will have a higher density than the reservoir/formation fluids to prevent any hydrocarbon influx. Prior to running in the production completion, the well is displaced to a lighter density completion fluid to encourage the hydrocarbons to flow into the wellbore and up the production tubing. If any integrity issues in the connections or the casing/liner overlap are present this could affect the overall efficiency of well production recovery, in addition to posing safety & integrity issues of the well construction. Hydrocarbons could potentially by-pass any safety related equipment in the well completion string.
