Gas supplies were stopped by Kazakhstan over pressure decline. Many buildings and companies in Bishkek were cut off gas to avoid accidents, Mamatisaev said.
During the first few days of continuous testing, production rates started with a flow of 5.5 MMscf/d of gas, a well pressure of 1,850 pounds per square inch or psi and minimal pressure decline. The well was later closed for eight days to allow memory gauges to be removed and to offer a preliminary assessment as to the minimum size of the reservoir.

Results: The A to S time and the entire anaesthesia time of the group that underwent spinal anaesthesia were significantly short compared to the times recorded for the group who underwent epidural anaesthesia, and the use of vasopressor was more frequent in the spinal anaesthesia group because their blood pressure decline was larger.
