Constraining maximum horizontal stress using wellbore breakouts — A case study from the Ordovician tight reservoir of the northeastern Oued Mya Basin, Algeria Available to Purchase

Rafik Baouche, Souvik Sen, Shib Sankar Ganguli, Salim Benmamar, Prakash Kumar
Journal: Interpretation
Published: 27 February 2024
Interpretation (2024) 12 (2): SB1–SB8.
DOI: https://doi.org/10.1190/INT-2023-0053.1
.... A cumulative of 110 m of breakouts are deciphered within the Ordovician Hamra Quartzite interval of the Oued Mya Basin from a 138 m acoustic image log. These breakouts are ranked as “A-Quality” following the World Stress Map ranking guidelines. We infer a mean SHmax orientation of N28°E ± 8°. Following...

—Numerical modeling of the thermal regime in the lithosphere of the Oued el-Mya basin, Takhoukht region. Solid line is the base of the lithosphere as determined by intersection of the current geotherm with solidus curve for peridotite (shown in Figure 4). Long dashed lines are isotherms. Moho = base of the crust; comp. transition = location of pyroxene peridotite-garnet peridotite compositional transition in the mantle. The considerable rise of isotherms is related to periods of thermal activation in the litho-sphere in the Permian-Triassic and Cretaceous. Reduction of the crust thickness occurred during basement stretching (in the Ordovician-Devonian and Cretaceous) and during Permian erosion.

—Burial and thermal histories of the sedimentary section, Takhoukht region, Oued el-Mya basin. (A) Paleoclimate history based on literary paleogeographic data of the region. (B) Burial, thermal, and maturation histories resulting from basin modeling. Note the considerable rise of isotherms in the post-erosion period is related to the Permian—Triassic thermal activation in the lithosphere. More moderate activation occurred here in the Cretaceous-Cenozoic. The temperatures of Silurian rocks did not exceed 85°C during the pre-erosion period despite significant amplitude of erosion. (C) Tectonic subsidence of the basement surface calculated in local isostasy approach by removing of sediment and water load (solid line) and by consideration of variations in densities of basement rocks (dashed line). The coincidence of solid and dashed curves provides an additional opportunity to control the sequence of the tectonic and thermal events in the lithosphere. STR1 and STR2 = stretching periods of the basement; TAC1 and TAC2 = periods of thermal activation in the basin lithosphere. (D) Variations in sedimentation (&gt;0) and erosion (&lt;0) rates for our variant of basin modeling. Dashed line marks the level of hiatus.
