Abstract
Abstract The first step in a method for forming a high heat resistant, non-dissolvent sand control pack, as for resisting the high heat eroding and dissolving effects of steam flooding comprises (1) forming a slurry of gravel of silicon carbide alone, or with garnet or zircon mixed therewith. The high heat resistant unconsolidated, permeable, non-dissoluble, and long-life sand control pack consists of the granular material silicon carbide alone, or with garnet or zircon mixed therewith for resisting dissolving during steam flooding for minimizing migration of sand and other granular materials into the well bore from the production zone of hydrocarbon bearing formation.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
122 words
A method for forming a pack of solid particulate material for resisting the deteriorating and dissolving effect of continuous hot steam flooding in a well bore for penetrating a petroliferous formation comprises, (a) selecting a granular material that is resistant to solubility at the temperatures of hot steam of silicon carbide, (b) mixing a slurry of the granular silicon carbide material, and (c) injecting the slurry of insoluble unconsolidated granular silicon carbide material into the well bore opposite the permeable formation to create a permeable pack of particulate material against the formation face thereby minimizing migration of sand and other formation particles into the well bore from the formation and particularly for resisting continuous high heat exposure, as from the steam flooding.
Claim 2
Independent Claim
122 words
A method for forming a pack of solid particulate material for resisting the deteriorating and dissolving effect of continuous hot steam flooding in a well bore for penetrating a petroliferous formation comprises, (a) selecting a granular material that is resistant to solubility at the temperatures of hot steam of silicon carbide, (b) mixing a slurry of the granular silicon carbide material, and (c) injecting the slurry of insoluble unconsolidated granular silicon carbide material into the well bore opposite the permeable formation to create a permeable pack of particulate material against the formation face thereby minimizing migration of sand and other formation particles into the well bore from the formation and particularly for resisting continuous high heat exposure, as from the steam flooding.
