Well Installation & Completion in Oro-Medonte

Well installation on the Oro Moraine in Oro-Medonte often involves completing wells in productive sand and gravel aquifers, which requires specific screening and completion techniques distinct from the bedrock well installations common elsewhere in the region. When an overburden well is completed in the moraine deposits, a properly designed well screen is installed at the production zone to allow water in while keeping sand and gravel particles out. The screen slot size is determined by grain-size analysis of formation samples, and a gravel pack may be installed around the screen to provide additional filtration in finer-grained zones. Casing above the screen extends to the surface and is grouted to seal the well from any overlying layers that could contribute poor-quality water. For Oro-Medonte properties where the overburden aquifer is insufficient, the well is completed into bedrock using standard open-hole techniques with full casing through the overburden. The moraine sand and gravel can complicate casing installation because these loose materials shift and settle, potentially creating voids around the casing that must be filled with grout. Well development after installation is particularly important in sand and gravel completions because residual fine particles from drilling can clog the screen and reduce yield if not removed. Our crews perform thorough development on every Oro-Medonte well to ensure the formation around the screen is clean and the well produces at its full natural capacity.
