Re: Well No. 13 Classon "B"Ja1mat FieldLea CoUnty, New Mexico

Gentlemen;

Attached are the results of core analysis of the Yates formation inthe above well. The data are presented in a tabulation and are alsoplotted on a graph having the same depth scale as the detail section ofan electric log. This facilitates making a correlation between the corelog and the subsurface logs.

The well was cored from 3,555 feet to 3,630 feet and from 3,685feet to 3,830 feet. The core was cut with a water base mud and intervalsselected by a representative of the Cities Service Oil Company wereanalyzed by Conventional Corestudy.

The porosity was measured using a "Boyle's Law" gas expansion porosi-meter.

Yours very truly,

DARRELL W. SMITH
