HALLIBURTON ENERGY SERVICES COMMERCIALIZES ADVANCED WIRELINE FORMATION TESTING SYSTEM
DALLAS, Texas - Halliburton Energy Services' logging and perforating product service line is offering its Reservoir Description Tool (RDT™) to the drilling and exploration segment of the oil and gas industry. By incorporating an innovative pumpout design with a digital control feedback system, the RDT tool continuously samples and monitors formation fluids, thus enabling the advanced wireline formation testing system to provide operators with accurate, extensive reservoir information. Halliburton Energy Services is a business unit of Halliburton Company (NYSE: HAL).
Typically, the primary focus when using wireline conveyed formation testers is to improve the quality of reservoir fluid samples. Through its advanced digital control feedback system, Halliburton's RDT tool is able to make instantaneous changes in pumpout flow rates to maintain a prescribed rate, significantly improving formation fluid sampling and pressure testing. The tool also combines a powerful pumping system motor with a hydraulic system that allows it to pump invaded fluids and formation fluids 50 percent faster than other wireline test tool.
"By monitoring fluid and formation properties in real time, operators can determine the optimum point to obtain the highest sample quality possible, especially where zones are tested over a wide range of overbalance pressures in a single trip," said Jody Powers, president, Halliburton Energy Services. "The RDT tool also has the ability to provide our customers with extended pressure range sampling through the use of two flow control pumpout sections. With this feature, the tool can obtain samples that are not possible with current generation tools."
The tool also has the ability to monitor up to five fluid and formation properties during testing that includes resistivity, bubble point, compressibility, horizontal and vertical permeability, and anisotropy. Simultaneously deployed, closely spaced dual probes were also engineered to increase reliability through redundancy, and to allow for advanced pressure-testing techniques. For example, formation anisotropy (kv/kh) can be determined through interference testing between the two probes, while additional formation diffusive properties can be calculated using new pressure-pulsing techniques between each probe.
The RDT tool's Zero Shock™ pressure-volume-temperature (PVT) sampling method can eliminate pressure transients during pumping and sampling, as well as perform closed-chamber PVT testing for the bubble point of the sampled fluid. The tester can be combined with existing open hole logging tools, and tool sections are interchangeable, which permits a complete wireline tool string to be configured to meet particular open hole formation evaluation and testing needs in a single trip into the well, saving rig time and costs.
Halliburton Energy Services provides products, services, and integrated solutions for oil and gas exploration, development, and production. Capabilities range from initial evaluation of producing formations to drilling, completion, production enhancement, and well maintenance – for a single well or an entire field. With more than 300 service centers in more than 90 countries, Halliburton possesses the global perspective that is increasingly important for energy exploration and production.
Halliburton Company, founded in 1919, is the world's largest provider of products and services to the petroleum and energy industries. The company serves its customers with a broad range of products and services through its Energy Services Group and Engineering and Construction Group business segments.
