Rock Rupture as Affected by Fluid Properties

Abstract: This paper concerns the rupture or breakdown of rock formations as related to drilling, completing, and stimulating production of wells, and comprises data compiled from a study of literature and records of treatment of oil and gas wells, and from tests conducted in bores drilled into rock cores and outcrops of rock. Results of the investigation indicate that the internal pressure to rupture cylinders of rock and to breakdown rock formations surrounding a bore in the earth is dependent upon the extent of intru… Show more

“…Thus penetration influences the breakdown pressure greatly. This has been recognized empirically [Scott et al, 1953], and, as a result, penetrating fluids are commonly used for the breakdown process. One is thus left with the four unknowns S,, S•, Sz, and 7 and with only the three equations (1, 2, and 15 or 16) With the data at hand the vertical stress is assumed to be known, and under favorable conditions the least horizontal stress can be approximately determined, S• • P• 8.…”

“…Such phenomena are often observed in oil and gas production drilling and are well attested in specialist literature. The artificial formation of hydraulic fracturing has been widely used by oil-well experts to increase oil production since the mid-20th century, when the theoretical bases of hydraulic fracturing in mountain rocks were developed (Scott and others, 1953; Zheltov and Khristianovich, 1955). Russian scientists are currently carrying out theoretical and experimental studies of this process applied to ice.…”
