| Resumo: | In the oil industry, artificial lift method sucker-rod pump (SPM) is the most used in Brazil. It
is predominant in number of wells and stands out for its low cost, simplicity and high energy
efficiency. This method uses traditional production tests to infer its production. Therefore, in
order to improve the monitoring of wells equipped by SPM, which use traditional production
tests, and lower costs with infrastructure, human resources and improving the accuracy to
determine production, a technique developed able to individually accompany the production
of the well. In this sense, this work presents a method to calculate the production from the
area of the dynamometer pump card and still develops a computational tool capable of
monitoring the production of a certain well. This method calculates the area, establishing
assumptions such as: leakage, tubing anchored or not, and pump filling factor. The validation
of the strategy developed was made by comparing the calculation of the production by means
of the method described and the production calculated by a sucker-rod pump simulator,
source of data validation. From the results, it was observed that the strategy developed was an
important tool when it was the monitoring production of wells equipped by SPM, since the
method provides to accompany the production of the well individually, guaranteeing greater
agility in the determination of production and problem solving. In addition, it is noted that
conventional production tests can be reduced by using production calculation techniques from
the pump card, tracking production in real time, economically reflecting in a cost reduction
and better decisions operating. |
