On 10 June 2018, Polskie Gornictwo Naftowe i Gazownictwo (PGNiG) completed tests in new-field wildcat Kulno 1 in the northern part of the 1/97/p Lezajsk-Rudka-Sieniawa contract in southeastern Poland (Carpathians). News is that the well tested commercial quantities of hydrocarbons (flow rates undisclosed) and by the end of the month, the well was handed over for hooking on-line.  Kulno 1, started on 2 May 2018 using the IRI Cabot â 750 (111) drilling unit, is located approximately 10 km northeast of the city of Lezajsk, close to the Kurylowka production license. The Lezajsk-Rudka-Sieniawa contract is situated within the Outer Carpathian Foredeep.    The well was targeting the autochthonous Miocene clastics (Upper Badenian-Sarmatian), with a planned final depth of 1,400 m.  The final depth of 1,368 m in the Cambrian series was reached on 19 May 2018. The autochthonous Miocene series were encountered at a measured depth of 1,305 m. In late May 2018, the operator commenced testing the well.  Background Information    The 503 sq km Lezajsk-Rudka-Sieniawa contract was granted to PGNiG on 14 January 1997 for a six-year exploration period and was extended as prompted, since.    The latest seismic acquisition in the area dates back to mid-2016, when PGNiG completed the acquisition of the Zalazie 3D seismic programme, partly covering the contract.    Several hundred wells have been drilled in the area following the WWII, leading to discovering many small- to medium-size gas fields. The fields are forming a northwest-southeast band of pools, ahead of the Carpathian thrust front, reflecting regional tectonic trend. The wells in the region are drilled to depths ranging from 300 m to 2,000 m, targeting pools traditionally found in the gas-bearing siliciclastic sequences of the Upper Badenian-Lower Sarmatian age (Autochthonous Miocene sandstones/mudstones), as well as, occasionally, within the Mesozoic sediments in the sub-thrust position.    The latest drilling operation in the tract dates back to mid-June 2016, when PGNiG completed with gas appraisal Dabrowica Duza 6. The well, drilled to the final depth of 1,500 m in the Precambrian basement series, tested commercial quantity of gas from three horizons - 831-838 m, 880-883 m, 887-889 m â located within the Upper Badenian-Sarmatian (Middle Miocene) series.
