INCREASING FORMATION STRENGTH THROUGH THE USE OF TEMPERATURE AND TEMPERATURE COUPLED PARTICULATE TO INCREASE NEAR BOREHOLE HOOP STRESS AND FRACTURE GRADIENTS
A method of increasing near-wellbore rock strength so as to mitigate or remediate lost circulation events through increased hoop stress in the near-wellbore in a subsurface formation comprises a) cooling a near-wellbore region of the formation, b) allowing a lost circulation material to enter the co...

Summary: | A method of increasing near-wellbore rock strength so as to mitigate or remediate lost circulation events through increased hoop stress in the near-wellbore in a subsurface formation comprises a) cooling a near-wellbore region of the formation, b) allowing a lost circulation material to enter the cooled near-wellbore region; and c) heating the near-wellbore region. |
