High-resolution imaging in oil-based mud environments
The Halliburton High-Fidelity Borehole Imager (HFBI) tool is a high-resolution microresistivity imaging tool for use in oil-based mud environments. It provides images comparable to those from a conventional microresistivity imaging device logged in water-based mud.
Three versions of the tool are available for differing environments. They include a 5-in. slim 6-pad tool (for 5⅞-in. holes), a standard 6-pad tool, and an 8-pad tool (available Q1 2020), providing 100% coverage in 8-in. boreholes. Each pad contains 24 buttons to provide the same level of detail that interpreters typically see from images recorded in water-based mud.
From thin beds to carbonates
The tool typically provides images at three frequencies — higher frequencies for lower resistivities and lower frequencies for higher resistivities. The ability to acquire data at generally high frequencies is what sets the tool apart from previous-generation resistivity imagers for oil-based mud. The frequencies can be set during prejob planning to optimize the tool’s operating range according to the formation resistivity. During processing of the data, the three frequencies can be “blended” together to provide a single optimized image.
The high-resolution images enable detailed structural and stratigraphic interpretation of the data, as well as fracture determination. From complex studies for reservoir modeling to rapid answers for completion decisions, the HFBI tool has you covered.
Identify thin-bed pay below the resolution of conventional logs
Determine fracture patterns and relationships, which may be conduits to hydrocarbon flow or thief zones
Examine the formation around fault zones and the potential impact on the completion program
Rapidly discern potential flow barriers
Understand the regional structures and stratigraphy to enhance reservoir management
