Sentence examples for true formation from inspiring English sources

True formation measured resistivity.

True formation resistivity at irreducible water condition, ohm-m.

This paper presents a numerical method to determine connate water resistivity from the true formation resistivity.

The present study suggests a reasonable method to determine true formation resistivity and to evaluate a reservoir for dynamic mud filtrate invasion by history matching field data.

These effective porosity values were then adopted for the water saturation evaluation using the following formula: S w  = (1/Ø) × (√R w /R t ), where S w  = water saturation, Φ = porosity, R w  = water resistivity, R t  = true formation resistivity.

The log response for the long normal log only provides a true formation resistivity if the bed thickness is significantly greater than the electrode separation (Kearey et al. 2002).

Resistivity logs have been consistently used to determine the saturation of water in the reservoirs by making use of the Archie's equation (Archie 1942) that shows a relationship between water saturation to the true permeable formation resistivity, the formation porosity and the formation water resistivity.

Filtration causes dual-laterolog responses to deviate from the true-formation resistivity.

Generalized inversion method was used to construct the present three-parameter joint inversion algorithm to obtain true-formation resistivity, depth of invaded zone, and resistivity of invaded zone simultaneously.

Considering that cell aggregation might confuse true sphere formation in liquid culture, we further assessed sphere formation in methylcellulose-containing semisolid culture to rule out this confusion.

True hyphae formation of the age3Δ strain was most efficient in YPD containing 10% bovine serum and germ tube formation occurred as efficiently as in wild-type background (albeit with a short delay and a reduced germ tube length compared to wild-type cells).
