## Frequently asked questions

### Which borehole driller in Port Harcourt has the best rating?

Ramec Integrated Services Limited (RISL) has the highest rating at 4.9 stars from 32 reviews. Geoplex Drillteq Ltd is next at 4.6 stars from 37 reviews. Liscon Geotechnical Limited shows 5.0 stars, but that comes from a single review, so it carries less weight.

### How many indigenous borehole drillers are listed in Port Harcourt?

Ranked currently verifies 14 indigenous borehole drillers in Port Harcourt, Rivers State. The page lists each one with its Google rating and review count where available.

### Why do some drillers have no ratings?

Nine of the 14 drillers have no Google reviews yet, so they appear without a star rating. That means we cannot judge their performance from review data. It does not indicate quality either way.

### How are the drillers ordered on this page?

Ranked orders the list using a combination of Google ratings, review volume, and profile completeness. Businesses with more reviews and higher ratings tend to appear higher. Placement is not for sale.

### Can I trust a 5-star rating from one review?

A 5.0 from a single review is one person's opinion. Liscon Geotechnical Limited has that mark, but it is not a reliable indicator of performance. Look for businesses with more reviews, such as Geoplex Drillteq Ltd with 37 reviews, for a broader picture.
