OKLAHOMA CITY– Schlumberger has unveiled the Pulsar multi-function spectroscopy service at the SPWLA 58th Annual Symposium.
The new service is said to provide the industry’s first complete cased-hole formation evaluation and reservoir saturation monitoring with open-hole logging quality.
This next generation in pulsed neutron logging features multiple detectors and a high-output pulsed neutron generator to improve acquisition accuracy and increase both logging speed and measurement precision.
Karin Hoeing, president, Wireline, Schlumberger, said: “Understanding both the formation lithology and fluid content is critical for making timely, informed completions decisions, particularly in complex reservoirs. In cost-driven markets, the Pulsar service makes it possible to perform a complete rigless formation evaluation that does not disrupt drilling schedules.”
The new service simultaneously obtains self-compensated traditional cased-hole measurements, an expanded suite of elements including total organic carbon and the new fast neutron cross section (FNXS) measurement. Directly sensitive to the volume of gas in the formation, the FNXS measurement differentiates and quantifies gas-filled porosity from liquid-filled and tight zones without requiring any open-hole data input.
