Abstract There is a fundamental interest in studying travertine rocks, and this to understand their structure, geomechanical behavior other particularities order guarantee proper use different engineering architectural applications, thus, evaluate the sustainability of travertines, natural resources, stability slopes, preservation cultural heritage mitigation possible anthropic risks. Travertin...

The geological storage of CO2 coming from large industrial facilities has been studied in detail for the last several years as a solution against the greenhouse effect and climate change in a number of countries. It is considered as a complementary solution together with the research for the non pollutant or/and renewable energy sources. One of the available options is the injection of the supe...

The present paper describes a parallel preconditioned algorithm for the solution of partial eigenvalue problems for large sparse symmetric matrices, on parallel computers. Namely, we consider the Deflation-Accelerated Conjugate Gradient (DACG) algorithm accelerated by factorized sparse approximate inverse (FSAI) type preconditioners. We present an enhanced parallel implementation of the FSAI pr...

Sand production is a universally encountered issue during the exploration of unconsolidated sandstone reservoirs particularly during production. The production of sand particles with the reservoir fluids depends on the stress around a wellbore and the properties of the reservoir rocks and fluids. Therefore, it is crucial to predict under what production conditions sanding will occur and when sa...
