(2024031) Case Study Results on Overcoming Massive Gas Interference from SRP Well Drawdown in Permian Basin

As operators draw down a well, massive quantities of gas are released into the wellbore which results in shut-downs and lost production. Using appropriate bottom hole assembly (BHA) best practices can help the operator pump through these gas slugs to maximize production and return on investment. Additionally, solid separation is an ongoing issue. Using a gas separator minimizes abrasion and corrosion related failures, keeping operating expenses lower.

The problem is twofold: Gas interference can lead to poor pump efficiency and severe sand issues can lead to sticking and excessive wear and tear on the pump. Both problems lead to unnecessary and costly operational expenses due to well failures and overall poor system efficiencies. 

Maintaining proper gas and solid separation widens operator options in regard to optimization and improved well control. This paper focuses on an all-in-one system that effectively allows operation through gas rates as high as 1900 MCF, as shown in case studies presented in this paper.

By maximizing separation area and minimizing downward fluid velocity, higher production rates are achieved in high gas-to-liquid ratio (GLR) environments. Installing this type of equipment reduces gas and sand interference, which in turn increases pump efficiency and extends the life of all downhole equipment. 

This paper presents the technology behind this combination gas and sand separation system and offers case study results that prove the positive impact of this tool on overall operating expenses.
