Welcome to Boreholes Experts Zimbabwe and Mutare Boreholes, your trusted partners in borehole drilling and maintenance.


We will delve into the critical aspect of borehole casing, explaining its importance, purpose, and benefits. This comprehensive guide aims to inform our clients about the essential role of borehole casing in ensuring the longevity and efficiency of boreholes.

What Is Borehole Casing in Zimbabwe?

Borehole casing is a large-diameter pipe inserted into a recently drilled section of a borehole to protect and support the borehole stream. Once a borehole has been drilled, it must undergo completion to become a production well. The raw sides of the borehole cannot support themselves, similar to how the bones of your spine protect the spinal cord.

The Purpose of Borehole Casing in Zimbabwe

The primary purposes of borehole casing include:
  1. Stabilization: It provides stabilization and prevents the sides of the borehole from caving in.
  2. Contamination Prevention: It protects the borehole from outside contaminants and safeguards freshwater reservoirs from the oil or gas being produced.
  3. Structural Support: It supports the borehole structure, ensuring it remains intact during and after drilling.
  4. Isolation of Zones: It isolates various zones with different pressures or fluids in the drilled formations.
  5. Fluid Loss Prevention: It prevents fluid loss into or contamination of production zones.
  6. Smooth Installation: It provides a smooth internal bore for installing production equipment.

The Process of Casing a Borehole

Casing a borehole involves running PVC pipes down the inside of a recently drilled borehole. The small space between the casing and the untreated sides of the borehole is filled with gravel pack to permanently set the casing in place. The casing is fabricated in sections, or joints, usually about 40 feet long, and joined together with solvent cement to form longer lengths called casing strings.

Benefits of Using PVC for Borehole Casing in Zimbabwe

PVC is the preferred material for borehole casing due to its numerous benefits:
  1. Corrosion Resistance: PVC is completely resistant to corrosion, making it ideal for borehole pumps that operate in environments prone to galvanic corrosion.
  2. Durability and Longevity: PVC piping ages well and is remarkably resistant to weathering and wear-and-tear, ensuring long-lasting protection for boreholes.
  3. Ease of Installation: PVC is simple to work with and requires few specialized tools, making it easy to install and maintain.
