oil and gas well drilling method "Slim Hole Drilling" (aka micro hole or small hole) is one of the most cost effective methods of
oil and gas reserve development. It
involves drilling smaller diameter holes and using small diameter
production casing and tubing. The use of small diameter well bore reduces
the overall cost of exploration drilling and reserve development.
The Oil Jet Pump is the industry
smallest and able to be conveyed inside 2-3/8 or 2-7/8 inch production
strings, thereby allowing slim hole operators to retain economical
operation factors associated with slimhole development methods.
Slim Hole Drilling Advantages:
Reduced Drilling Mud Usage
-resulting in lower Cost, Footprint (50x70 feet) & Disposal.
Smaller surface casing and
conductor sizes - reduces cost on pipe and installation
Can be used for High Angle
and Horizontal Wellbore from existing wells
Could be used for CO2 Flood
Injection holes or wells
Reduced drilling time by
Hole Drilling Concerns:
Ability to rework wells
Limited space for mechanical
Future use of microhole
