EATON DRILLING CO
Water Well Drilling Contractor
Eaton Drilling has perfected its drilling and construction procedures to optimize wells for production and longevity. By providing all phases of well design and construction in-house, we can better assure our customers that their wells will be completed on time and within budget. As a general principle, we strive to make no major decisions in the field. Prior to well construction, we conduct a thorough subsurface investigation of the proposed site as part of the well design. This includes researching existing wells in the area and test hole drilling to enable geophysical logging and sieve analysis of recovered subsurface gravel samples. Geophysical and production data from neighbor wells we use for referencing and comparison.
Along with the driller’s descriptive log, we use this information to provide our customers with a complete, detailed design of the proposed well. Alongside the design, we also provide a detailed description of the subsurface geologic formations encountered, the geophysical log, water quality predictions as well as grain size composition reports of sand and gravel samples from water-bearing zones. Designs show placement of casing perforations in production zones as well as depths and thicknesses of surface and strata seals. We mark the geographic location of test holes in GPS coordinates and provide maps showing their location in relation to nearby surroundings.
-During construction, borehole reaming for the cased well begins only after all materials arrive on site. This prevents delays that would otherwise expose surrounding water-bearing formations to invasive drilling fluids longer than necessary.
-Overexposure can lengthen the well development process that follows.

Test holes are exploratory boreholes that we drill at each proposed site prior to further drilling and construction of the full diameter, production well. Test holes are deep, small diameter borings drilled to provide subsurface sand and gravel samples, and access for geophysical logging. Our experienced design team interprets data from test holes, along with descriptive logs provided by the driller, to infer the depths and thicknesses of water bearing formations that guide the design of the proposed well.

To meet the production needs of the customer, we use information gathered during the Exploratory Drilling phase of the project to design wells optimized for the subsurface geology of site. Information used includes the driller's descriptive log, sieve analysis results of production zones and the geophysical log of the test hole. In a nutshell, these show the depth ranges of water-bearing formations as well as their particle composition, to guide the selection and placement of perforated casing sections, annular gravel pack and sanitary seals of the cased well to be constructed.

At Eaton Drilling Co., Inc. we custom design each well to meet the needs of the customer given the subsurface geology of the location. From the test phase, information from descriptive and geophysical logs as well as test hole cutting samples indicate the depths and composition of water-bearing formations specific to the site, so that the cased well can be constructed accordingly. Our experienced crews use modern, well maintained equipment, and work around the clock to maintain the best conditions for drilling and completing jobs quickly. Read More
