Kriging is a standard method for conditioning surfaces to observations. Kriging works for vertical wells, but may produce surfaces that cross horizontal wells between surface observations. We establish an approach that also works for horizontal wells

We consider the problem of depth conversion at the Edvard Grieg field. Measurements of deep directional resistivity suggest that the top surface on Edvard Grieg is much smoother than what is indicated by the interpretation of seismic reflectors. We i

We demonstrate accurate prediction of geological surfaces by imposing consistent physical and stochastic relationships between surfaces. The accuracy is improved by using all relevant information collected in wells: well points, zonation in horizonta

We describe the implementation of integral screening in the integral-direct SCF calculation of cubic response functions. The screening is applied to all computational steps that involve the construction of Fock matrices or one-index transformed Fock

Using London atomic orbitals and a recent parallel implementation of our second-order ab initio property code, we have determined the Hartree–Fock limit for the magnetizability of C60 to be −359±5 ppm cgs, in excellent agreement with earlier bas

The robust use of horizontal well data in 3D stratigraphic horizon modeling is an important challenge. In many reservoir models there are inconsistencies between the zone log information observed in horizontal wells, and the horizons and zones of the

In this paper, we prove the benefit of a consistent and quantitative use of 3D seismic data to constrain the facies model built on a complex reservoir, Snorre, located in the Norwegian Sea. The workflow starts with the application of Bayesian seismic

In MP2‐GGn theory, the second‐order Mo/ller–Plesset (MP2) energy is recovered by a combined Gaussian‐orbital—Gaussian‐geminal (GG) expansion of the first‐order wave function. While the restriction of geminals to doubly occupied orbital
