László Paczuk: EUROGASCO and MAORT's Production Methods
Improvements to crude oilproduction implements 60 The rational exploitation of the fields demanded the measurements - concurrent with production - that allowed for the development of processes playing out in the formations. Characteristically of the improvement of implements, when well B-3 was surveyed in 1938, the Haliburton wireline and the Humble type bottom pressure metering instrument was still transported on horse-drawn cart. The wireline was still operated using manpower at this time. The clockwork in the Humble instrument rotated the chart drum. Not much later after this, the wireline was already mounted on the chassis of a scrapped motor vehicle, and the engine of a 500 cm' motorcycle served to pull the instrument up. Motor vehicles appeared after 1941. Closed (24-hour) and mid-production bottom pressure metering was performed every 3-6 months. After measurement results were processed, isobar maps were charted. This made keeping track of production's regional uniformity possible. Multiple bean capacity metering was also on the agenda in order to make the various well yields accurate. Information derived from such knowledge was used as the basis for carrying out bean optimisation. PVT-cells appeared later on, and this allowed for in-depth sample-taking, and more state-ofthe-art exploitation analyses. Permanently installed equipment was used on flowing mode wells for removing paraffin from the tubing. As reservoir energy decreased - taking the substantial natural gas reserves of the field into consideration - it was fundamentally lift gas working that was implemented. Deep-well pump beams were only installed on a couple of wells, and these were driven with Thomassen onecylinder gas engines. Propellant gas was taken from the well's tubing. Waukesha gas engines running on PB-gas or natural gas were also used. 6 ' The Hungarian Petroleum Museum possesses one of these beam units.
