Schlumberger Launches New Fluid Mapping-While-Drilling Service
SpectraSphere service uniquely enables the understanding of reservoir properties while drilling for improved reservoir characterization , well placement and reduction in overall well construction cost
Schlumberger launched the new SpectraSphere * fluid mapping-while-drilling service at the 2017 Offshore Technology Conference .
The service is the industry ’ s first to deliver downhole fluid composition during drilling with real-time pressure measurements-while-drilling . Applicable in a variety of environments , from exploration wells to highly deviated development wells , SpectraSphere lowers risks associated with fluid analysis and sampling operations while enhancing well placement , maximizing reservoir contact and ultimately boosting future production .
“ Understanding the parameters of the reservoir in real time is critical for all our customers during all stages of field development ,” said Richard Brown , president , Drilling & Measurements , Schlumberger . “ The SpectraSphere service enables customers to obtain laboratory-quality fluid analysis while drilling , which reduces the overall cost of operations and risks associated with conventional fluid analysis .”
The SpectraSphere service is the industry ’ s only service to enable real-time fluid mapping by providing critical fluid properties , including fluid composition , fluid typing , fluid fractions and gas / oil ratio while drilling . The reliable characterization of these properties is essential for estimating reserves , optimizing completions , designing surface facilities and meeting production goals .
The service has been field tested in the Gulf of Mexico , Middle East , Africa , the North Sea and offshore Malaysia . While developing a field offshore Malaysia , a customer used the new service to acquire formation fluid samples and pressure measurements in a highly deviated wellbore that intersected pressure-depleted zones with increased risk of differential sticking . The customer obtained all fluid samples and pressure measurements in one run , with fluid samples showing less than 1 % contamination . The customer completed sampling in two hours per station and eliminated the need to conduct further formation testing in two additional wells , saving three operating days .
