Using three independent measurements, Halliburton’s new Reservoir Monitor Tool 3-Detector (RMT-3D) pulsed-neutron tool can log and calculate water, oil and natural gas saturations within reservoirs, helping identify pay zones, the company said July 16.

The tool has been successfully used in the Permian Basin, in a CO2 enhanced recovery flood.

The measurements the tool uses are Sigma, CO, and SATG, and using the different methods allows operators to calculate saturations more accurately. Using just one or two can reduce accuracy depending on formations’ conditions and fluids, the company said.

The data is collected with one trip into the hole—the tool is deployed through the casing. This saves costs and reduces nonproductive time, the company said.

Reservoir Monitor Tool 3-Detector will be useful in mature fields, which make up 70% of worldwide oil and natural gas production. Challenging environments such as secondary and EOR methods, which can involve water, steam, and CO2 flooding, will benefit from the tool.

“Halliburton continues to add technologies that support our customers’ needs and operations,” said David Topping, vice president for wireline and perforating. “With the addition of the RMT-3D technology to our portfolio of solutions, we have the capability to provide valuable answers to help our customers increase recovery on their wells.”

Halliburton Co. is based in Houston.
