Abstract
Objective. It looks like a MWD static survey takes so short time just few minutes, however, when you calculate total time for taking all surveys during drilling one well you will get considerable number. The objective of the article is to analyze how MWD telemetry speed affects the total well construction cost.
Materials and methods. The article contains calculation of time spent on such operation like taking MWD static surveys and relogging, how it affects total well construction time and cost. It also describes some methods for increasing the telemetry rate.
Results. According to the given analyses results, the telemetry rate can be increased twice with minimum cost. The increase doesn’t affect the MWD signal quality. Due to double telemetry rate the time spent for taking MWD surveys and reclogging will be twice shorter. That leads to the lowering the total well construction time by 0,57%, the total well construction cost will be decreased accordingly.
