Chapter One — 1.1 Background to the Study

Research interest in well completion design has grown steadily in recent years, driven by its demonstrated relevance to selected gas reservoirs in both laboratory and field settings.

Much of the existing literature on well completion design draws on data and conditions that differ from the local context in which selected gas reservoirs is typically studied or produced, limiting the direct applicability of prior findings to oil recovery efficiency.

1.2 Statement of the Problem

There is currently limited empirical evidence on how well completion design affects oil recovery efficiency in selected gas reservoirs, making it difficult for researchers and practitioners to draw reliable, context-appropriate conclusions. This study addresses that gap through a structured investigation.

1.3 Objectives of the Study

1. To determine the effect of well completion design on oil recovery efficiency of selected gas reservoirs.
2. To evaluate the extent to which well completion design influences oil recovery efficiency.
3. To identify the conditions under which well completion design has the greatest effect on oil recovery efficiency.
4. To recommend practices based on the observed relationship between well completion design and oil recovery efficiency.

1.4 Research Questions

1. What is the effect of well completion design on oil recovery efficiency of selected gas reservoirs?
2. To what extent does well completion design influence oil recovery efficiency?
3. Under what conditions does well completion design have the greatest effect on oil recovery efficiency?
4. What practices can be recommended based on this relationship?

1.5 Significance of the Study

This study is significant to researchers and practitioners working with selected gas reservoirs, offering evidence on how well completion design relates to oil recovery efficiency. It also contributes to the broader literature in petroleum engineering by documenting findings specific to the conditions under which the study was conducted.

1.6 Scope of the Study

The study is limited to examining Well Completion Design and its relationship with oil recovery efficiency in selected gas reservoirs, reflecting a clearly defined scope of analysis; conclusions are drawn strictly from the conditions and samples used in the study.
