Pulsar Helium announced early this week it received the wireline log interpretation from Asia-Pacific Formation Evaluation Services Pty Ltd for the Jetstream #1 appraisal well.
The wireline log interpretation is a technique that uses cables and sensors to analyze various properties of rocks and fluids in the well.
Wireline logging data provides valuable information for Pulsar Helium, including reservoir characteristics.
The wireline logging data detected a predominantly gas-saturated interval which has been interpreted between 1,650 - 2,200 ft (503 – 671 meters) containing discrete zones where productive permeability appears to occur.
Drilling observations and log data interpretation suggest the presence of permeable zones in the form of fracture and/or vuggy porosity within the host igneous rock.
“ We are delighted t o receive these initial positive results from the well and we are acquiring the complementary wireline log data, pressure and flow tests as well as the additional lab results as part of our ongoing testing program. We look forward to updating shareholders as we progress,” said Thomas Abraham-James, President and CEO.
Additional wireline data is scheduled to be acquired when Jetstream #1 is being prepared for the upcoming pressure build-up and flow testing operation.
Due to abnormally high winter temperatures and the earlier-than-anticipated onset of spring load restrictions on local roads, the well-testing package, which includes flow testing, a pressure build-up program and the collection of pressurized gas samples for laboratory analysis, is delayed until mandated road conditions allow heavy traffic to return.
The wireline logging data is hot off the heels of Pulsar Helium’s announcement earlier this month that the appraisal borehole tested for 13.8% helium concentrations.
When the natural gas pocket was originally drilled into, the team at Pulsar took on-site tests to calculate helium concentration using a mass spectrometer.
This mass spectrometer measured helium concentrations of up to 12.4%, but to get a more accurate reading, the team sent 11 samples of the gas off to two different laboratories.
After analyzing the samples at the lab, Helium contents of up to 13.8% were measured from one of the samples obtained at 1,801 ft in-hole depth.
The full suite of gas data was sent to Dr. Peter Barry, a noble gas isotope geochemist and Associate Scientist (an advisor to the Company) at the Woods Hole Oceanographic Institution (WHOI). He concluded that the value of 13.8% helium represents a minimum source estimate for helium due to the clear presence of small amounts of atmospheric (air) contamination in the samples.
The presence of this contamination decreases the measured helium content relative to the true source helium concentration.
“Comparing this to our extensive database for helium occurrences around the world, we are pleased to say the results from the Jetstream #1 appraisal well are the highest helium concentrations that we have ever seen,” said Cliff Cain, CEO of the Edelgas Group (an international gas advisor firm that is engaged by Pulsar).
