Abstract

In this work, the risks, non-technical and operational challenges encountered during well clean up and test on Niger Delta gas wells are assessed based on practical experience on four gas wells worked on by the authors. Previous works on general challenges and improvements in well clean up and tests were consulted, which formed the bedrock of this review paper. The reservoir and wells worked on are described. The reservoir is a non-associated gas reservoir in one of the Niger Delta fields. The challenges faced in the course of the cleanup and well test services on the four gas wells are presented in section 3 of the work. These challenges include issues of safety onsite; logistics management; commercial/contractual challenges and operational challenges like coiled tubing (CT) breakdown, CT inability to get to targeted depths, etc. The recommended and adopted solutions to the challenges are presented in section 4 of the work. The entire section 5 is a robust assessment of risks in gas well clean up and test operations. Risks probability, impact, consequences and mitigation methods are presented in Tables 1 to 5 of this section. Adhering to the recommended solutions and mitigation methods for the challenges and the risks illustrated in this work, would help eliminate downtime and unwanted happenings in the course of gas well clean up and test thereby making operations very successful.
