Pump Down Assemblies
Applications
- Perforating and cased hole logging in highly deviated and horizontal wells
Features
- Common mandrel for multiple swab cup sizes
- Rigid, durable rubber swab cups
Benefits
- One size tool can be used for multiple casing sizes
- Flexibility with range of services
With the increasing complexity of wells drilled, gravity alone is not adequate for conveying wireline logging tools and perforating guns to target depth. Traditionally, expensive and time consuming operations such as tractor and E-Coil have been implemented to reach depth. It is necessary to adopt more efficient and economical means for such applications. One such method involves pumping the toolstring downhole utilizing a pump unit at surface. By increasing the cross-sectional area of the toolstring, a larger force can be generated by the fluid that is being pumped downhole by the pumping unit. With the winch driver inside the logging unit providing enough cable slack, the toolstring is effectively pumped downhole to the target depth.
Titan Pump Down Assemblies are available for various sizes and services. The in-line option consists of a mandrel and rigid, durable rubber swab cups. The rubber swab cups are interchangeable for different internal casing diameters with the same mandrel making it economical when operating in different casing sizes.
Perforating gun Pump Down Assemblies are also available that directly screw into the bottom of perforating guns. They utilize a metal gauge ring that acts as a swab cup. The assembly is hollow such that detonators can fit inside.
