The stimulation potential of a tight "chalky" formation using closed fracture acidizing was successfully demonstrated. The stimulation consisted of a pad-acid treatment followed by a closed fracture acidizing stage. The step-rate injection test with seawater established a fracture gradient of 0.71 psi/ft (16.1 kPa/m). The high leak-off coefficient calculated from the mini-frac was primarily attributed to the matrix acid job prior to the frac. Temperature surveys run following the main frac indicated an exposed fracture height of 70 ft (21m). Pressure transient testing indicated an etched fracture half length of 200 ft (61m). Additional production enhancement methods, pressure maintenance, gas lift, etc., may be necessary to maintain the high production potential of the stimulated reservoir. The wellbore tubular goods were also found to greatly impact well stimulation and production mechanism. Further stimulation testing in this field is recommended to fully evaluate the best field exploitation technique.
