NOVEL ACID SOLUBLE ABRASIVE MATERIAL FOR ABRASIVE JET PERFORATION THROUGH COILED TUBING AND TS-TOOL FOR CARBONATE GAS WELL – YARD TEST

Abstract

Coiled tubing is used in oil and gas well production with the aim of increasing oil field production. The efficiency of this process is reproduced in this material, with practical applications in carbonate rocks, also presenting the conditions of applicability of the method (the maximum friction coefficient, the optimal depth of the intervention zone, the working conditions during the operations to increase the recovery). The surface weight variation graphs with depth are also shown (Theoretical lockup and Predicted surface weight during CT-RIH and CT-POOH considering default values for the coefficients of friction for 8.5-in OH section and 6-in OH section). The 55% increase in well productivity after using this technique makes the coiling tube useful at over 1000m depth.
