Abstract
The method of production is divided into two: natural flow and artificial
lift. Along with the time of production, the reservoir pressure drops and this
has resulted in reduced levels of the production wells. Then to overcome this
problem can be done by means of artificial lift. One of these artificial
methods is Hydraulic Pumping Unit (HPU).
The basic concept
in HPU's own evaluation is to determine displacement pump that is adjusted to
capabilities of production wells, which pump displacement depends on parameters
of the stroke length (SL) and the pumping speed (SPM). If the pump displacement
is much higher than the production capabilities of a well, there will be damage
to equipment faster. The method used for evaluating HPU is API RP 11L .
ALJ-099 wells are
oil wells that are in the field YLJ. Based on the analysis of the Vogel IPR
curve obtained maximum production rate (Qmax) of 236 bfpd,
evaluation of results obtained optimal rate (Q 80%) was 188.93 bfpd with speed
pump 4 spm and stroke length pumping 107 inches, and 75% pump efficiency.
