Standard sampling programs denote a time-consuming process and often prove costly in terms of rig time and well wireline sampling work.
A new breakthrough technology called the GeoTap IDS fluid identification and sampling sensor now makes it easier to perform similar hydrocarbon sampling process by eliminating rig costs and other wireline process.
Halliburton has successfully conducted field-tests on the GeoTap IDS sensor for BG Norge. The test was carried out at Norway’s drilling rig, Bredford Dolphin.
The GeoTap IDS enables the operators to sample the reservoir formation fluids during the drilling process, with an instrument positioned on the logging-while-drilling (LWD) assembly. This feature makes the GeoTap IDS suitable for those surroundings where significant amount of cost is involved in the drilling process. For instance, in deepwater exploration wells using a standard sampling program may not be feasible and will involve a huge expenditure.
The GeoTap IDS ensures that after the drilling process, operators can check several fluid samples in a matter of hours rather than days. This option ensures that less polluted samples are produced, and helps minimize any damage on the boreholes.
Obtaining multiple sample collection during the drilling process also enables the operators to characterize the fluid variability. This sample differentiation helps in recognizing potential reservoir compartmentalization. The GeoTap IDS also allows optimal use of wellbore placement and reservoir production over the reservoir’s life.
Halliburton Scandinavia’s Country Vice President, Jorunn Sætre, expressed his happiness on the positive results of this technology, and said that the GeoTap IDS will boost operators’ efficiency.
According to Sperry Drilling’s Vice President, James Bement, the GeoTap IDS eliminates the need for collecting additional fluid data, thus minimizing costs and enhancing well economics. He stated that at present, the GeoTap IDS sensor is the only technology available in the market and that the company is looking forward to increased demand for their service.
