Cole Bros Well Drilling specializes in professional water well drilling services for homeowners, farms, businesses, and municipal clients across a 50-mile radius in Oceana County and nearby Michigan communities. New well installations and deep well drilling require technical skill, thoughtful design, and adherence to state regulations. With origins dating to 1940, Cole Bros blends time-tested methods with modern drilling equipment to produce wells that meet performance expectations and water quality standards.

Types of drilling and when they’re used

Borehole drilling

Standard approach for most residential and small commercial wells. We select bit size and drilling method based on subsurface conditions.

Deep well drilling

Required when shallow aquifers do not supply adequate yield or when deeper, better-quality water is present. Deep drilling often involves heavier equipment and longer project timelines.

Geotechnical and test drilling

Performed to investigate subsurface conditions prior to full well installation or for geothermal projects.

Our drilling process step-by-step

Site evaluation and pre-drilling investigation

We review available well logs, historical site data, and conduct a site walk to assess access and potential environmental concerns.

Permitting and easements

Cole Bros assists with permitting and coordinates with local authorities to ensure compliance.

Mobilization and site preparation

Drilling rig setup, erosion control, and protective measures to preserve landscape and access roads.

Drilling and formation logging

We drill to the required depth while recording strata, water strikes, and conditions to determine optimal casing and gravel pack needs.

Casing installation and sanitary sealing

Install corrosion-resistant casing sized for pump requirements and perform sanitary grouting to prevent surface infiltration.

Gravel pack and well development

When necessary, we install filter pack material and develop the well with surging and pumping to remove fine materials and maximize yield.

Well yield and drawdown testing

Perform pumping tests to measure sustainable yield and decide on pump sizing and storage requirements.

Pump installation and system start-up

If requested, we install the selected pump, pressure system, and electrical controls followed by system commissioning.

Water quality testing and final documentation

Samples taken for bacteriological and chemical analysis, with written reports delivered to the client.

Materials and equipment we use

  • Drilling rigs selected for local geology (mud rotary, air rotary when needed).
  • High-grade PVC or stainless steel casing to resist corrosion and meet code.
  • Sanitary well caps, grout, and surface seals to prevent contamination.
  • Gravel pack materials tailored to aquifer characteristics.
  • Industry-standard pumps and controls sized via measured performance data.
