The annual XXV Science-Practical Conference "Modernization of The Russian Geophysical Complex" has been held in GK "Kandry-Kul"
under the aegis of the Geophysical cluster "Kvant" and MOO EAGO. "Alend" Ltd has presented the report "The Adjacent Formation Testing",
that means execution of hydrodynamic researches of two adjacent intervals (objects) in an open wellbore for a single running-in of a set
with selection of gas samples.

Well tests in the process of drilling with the use of testing equipment running-in on tubes have been carried out in the
Irkuts region. The innovation of these operations are in the use of anchor equipment (without support on a bottom-hole), and
in testing of two independent objects for a single run of a unit, as well as in gas sampling. The gas inflow from the low object,
and very aerated brine water from the upper object have been received.

Operations on field-geophysical researches have been started in the Republic of Uzbekistan.

Works in the well ¹ 28 have been successfully carried out on hydrodynamic survey of a gas-bearing layer in an open well-bore
with the use of the ZPKM 2Ì-127 set, with brief moving of the gas inflow to the daytime surface and registration of the pressure build-up curve.
The gas flow rate has been determined by two methods. The 1-st method - analytical, based on calculation of overflow fluid volume with
account of empty space volume in drilling tubes and recalculated to surface conditions. The 2-nd method - based on approximate calculation
of the gas flow rate after shutting the well in the first moment of time (on the pressure build-up curve) according to recommendations of
GASPROM 086-2010 (Instruction on complex surveys of gas and gas-condensate wells). In the results of calculations comparable values of the gas flow rate
have been achieved with account of which filtration-volume capacities of the layer have been determined.

Formation surveys on the well ¹ 41 in an open well-bore have been carried out with the help of the combined set ZPKM 2Ì-127 and IG-127
in the interval of 5100-5180 metres. Self overflow of fill-up fluid from annular space to a measuring container have been received,
as well as after the set lifting the methan has been extracted from a sampler (inspite of the lack of gas flow to the daytime surface).
Calculation of the gas flow rate has been done by analythical method with account of phisical-and-chemical gas properties and volume of extracted
fluid to the surface. This method of gas flow rate calculation is reflected in works of Ryazantsev N.F (“Testing of Wells in the Process of
Drilling”, 1982) and Yasashin A.M. (“Exposure, Sampling, and Testing of Formations”, 1979).
- March-April, 2019
Formation testings have been successfully conducted in the open well-bore ¹21 of the Artobay-Sartobe oil field (Republic of Kazakhstan).
The record temperature has been fixed for all formation testings on tubing which had been carried out earlier – 155 Centigrade.
The formation testing of the well-bore ¹42 of the Chinarevski oil-and-gas field (bottom-hole 5,106 m), with the help of the kit ZPKM-127,
the hydraulic valve IPM-127, and the reduction valve KR-127 used for sampling of hermetic sample, has been conducted.
In spite of actual absence of gas inflow, samples have been obtained from the sealed sampler located between the ZPKM-127 and the IPM-127.
The site was considered to be promising.

Recording of an inflow profile in the horizontal well 1HW has been carried out. The technology of works with autonomous tools lowering
on rods has been developed.
- November, 2017
A successful transaction on acquiring of the industrial base located in Usinsk has been conducted, as well as a warhouse, geophysical hoists,
sets of geophysical instruments for operations in enclosed well bores (including a modern set MAGIS), etc.
- September-October, 2016
Formation tests were succesfully conducted at the 201 Punginskaya gas well. During these tests the downhole samplers were used which provided
sampling of hermetical gas probes in formation conditions. The probes were sent to analysis into a chemical laboratory. The works were carried out by
R. R. Mavletov and An. N. Irbakhtin.
- April, 2016
Geophysical tests were conducted in an open borehole. That was a start of a new complex trend in conducting of borehole geophysics.
- October, 2015
Comprehensive tests of the exploratory Well 21P Nertsetinskaya have been successfully carried out. With the use of a formation tester of the 45mm
inside diameter, the closing of the well on the borehole has been done, after which it has been brought to a flowing mode. Deep samples of fluids have been
taken out.
