A Design responsible for more than thirty parameters of drilling projects, and a computer program to create groupings of the wells of a pad with consequent calculations of technical-economic characteristics, are developed and tested, covering a small surface area on land and a maximum interference with the reservoir downhole.

PAD wells are mainly installed with Packers/penetrators, SSSV (subsurface safety valves) for well bore protection from any abnormal high pressure, the casing is secured with the non-beaded packers and the tubing is secured with an SSSV that is activated manually through a capillary tube connected up to the surface.

Here we present the performance of electrical submersible pumps in PAD wells installed with TDV (Tubing drain valves) and without TDV and the effect of the gasses accumulated in the annulus that can affect the performance of the electrical submersible pumps which can cause gasses locks or ESP trips and this can be classified as below:

  • PAD Wells with TDV

  • PAD wells without TDV

The above classification can be further branched into the below:

  • Higher Distance between Packer and Intake

  • less distance between Packer and intake

using the daily monitoring and the sensor parameter charts and studying the history and performance of the ESP we will analyze each cases separately to get to conclusions and recommendations on which case is better to design for PAD wells that can efficiently increase the performance of the ESP and increase the ERL (Equipment run life).

In addition, this paper will discuss the effect of accumulated gasses trapped in the annulus on the ESP cable.

Based on the conclusions for each case, this paper will provide recommendations to enhance the equipment run life of the ESP system to avoid premature failures, gas lock and smooth operation for such cases.
