| Sand production is an undesirable phenomenon that occurs in wellbores that extract resources from sandstone formations. It presents a significant challenge to the advancement of oil and gas operations. The main implications of sand production include the disintegration of geological formations, the deterioration of both surface and downhole systems, reduced hydrocarbon extraction efficiency, and various environmental concerns. These challenges could result in annual costs amounting to billions of dollars for the petroleum industry. Thus, this study was motivated, and a field case study in southern Iraq was conducted to introduce the predictive techniques that depend on the geomechanical and physical properties to foresee and mitigate the possibility of sand production hazards. Moreover, seven threshold criteria were utilized to identify the critical limit at the onset of sanding. These criteria include unconfined compressive strength (UCS), total porosity (PHIT), shear modulus and rock compressibility ratio, sonic compression wave, B-index, S-index, and Ec-index. Additionally, some of these techniques are strongly related to elastic and strength rock parameters; hence, to perform them accurately, more appropriate correlations were used for the area of interest. The results indicate that sand production is likely to occur when the threshold values for the UCS, B-index, and S-index techniques fall below 4,200 psi, 1.6 × 106 psi, and 9.2 × 109 psi, respectively, while the value of PHIT exceeds 20%. Finally, this investigation could be utilized as a guide for optimizing sand managing to achieve maximum completion performance. | ||
