This document is a technical well log and computation sheet for water recovery services. The file contains two pages: the first is a hand-drawn schematic diagram of Exotic Well #1, and the second is a formal computation sheet dated 4/14/61 for the well log at a Portland, Oregon location.

The well schematic indicates dimensions of 20' x 75' with a 2c HP pump and 8" column. The well profile shows a static level at 10 feet below ground, with gravel and water conditions extending to 19 feet. The diagram identifies 31.5 feet of perforations within the well casing, with a 72-foot bottom fill and 75-foot bottom depth. The computation sheet provides a detailed stratigraphic log showing subsurface materials from the surface to approximately 75 feet deep, including overburden, large rocks, river gravel, small rocks, water-bearing gravel, cemented gravel, and river gravel with boulders at depth. A drawdown measurement of 53 feet at 880 GPM is noted with a temperature of 47°F. The pump type is identified as Large Boulder Centrifugal. This appears to be technical documentation for water well development and characterization rather than a federal contract solicitation.
