Maximize Recovery Using Hydraulic Fracturing in Horizontal Wells

Challenge

How can I isolate individual zones in my horizontal wells during stimulation in order to enhance and maximize hydrocarbon recovery?

Solution

Brazil’s pre-salt horizontal wells will eventually need stimulation, even if not at initial completion. As laterals are more commonly being extended thousands of feet, quite often they may be drilled through multiple fault blocks where the stress field can drastically change from one section of the lateral to another.

Historically, stress effects have been considered primarily for borehole stability concerns, but become much more important to production potential if hydraulic fracturing is necessary for stimulation. Technology advancements have significantly broadened the industry’s ability to effectively place multiple fractures at pre-selected locations along a lateral section.

Reservoir zones must be isolated and stimulated individually during the well completions process.  Halliburton offers a variety of leading technologies to address these issues. We also offer stimulation products and services that are effective in multiple zone fracturing, ensuring precise control of fracture placement.

Halliburton's patented fracturing service uses dynamic diversion of fracturing fluids to allow for multiple treatments to be performed in the same well without mechanical zone isolation. In most cases, several frac jobs can be performed in a single pipe trip when using our service.

With our frac-pack experience dating back to the early 1990s, we have delivered unprecedented successes resulting in record-breaking wells in Brazil’s deepwater and ultra-deepwater reservoirs. Halliburton has performed over 100 horizontal deepwater gravel pack operations in Brazil, installing over 67,000 m (222,189 ft) of screen—which is a record in Brazil. We also hold the record for  Brazil’s deepest deepwater frac pack , performed in 2,485 m (8,152 ft) of water.
