Boxplot of dimensionless production temperatures for various values of wellbore spacing L/(2R). The dimensionless standard deviation \(\sigma _h/\left\langle w \right\rangle\) is equal to 0.25 and the Hurst coefficient \(\zeta\) is equal to 0.8. The lower and upper edge of the box represents the first and third quartiles while the solid red line represents the median value. The lower and upper whiskers of the boxplot are defined as 1.5 times the first and third quartile value, respectively, and the red plus signs represent the outliers. The dashed red line represents the base case (no aperture variations) value of 0.8
