Background: 2022, an Indian PSU was engaged in the Exploration & Production from a field. During initial exploration period, production testing were carried out for a very short duration and were discontinued due to high viscosity & poor in flow of oil to the well bore. Operator was facing challenges in casing design and connection (BTC) when dealing in HPHT wells; Like unable to withstand the extreme condition, leakages, thread damage and time taking installation or make-up issues.

Solution

UDT suggested using its revolutionary casing pipe connector, known as the UDT Leopard, which offers much significant improvements over traditional connectors as a pilot case. UDT Leopard features an advanced design that enhances sealing capabilities, prevents thread damage, and streamlines installation procedures. Its innovative features include:

• Dual-Seal Technology: The UDT Leopard incorporates dual-seal system that provides superior leak resistance, even in harsh drilling environments. This technology minimizes the risk of casing leaks, ensuring the integrity of the wellbore and reducing the potential for costly remediation efforts.

• Thread Protection Mechanism: Traditional casing pipe connectors are prone to thread damage during installation, leading to decreased reliability and increased maintenance costs. The UDT Leopard utilizes a patented thread protection mechanism that minimizes the risk of thread damage, prolonging the lifespan of the connector and reducing the need for frequent replacements.

• Tool-Free Installation, Installing traditional casing pipe connectors often requires specialized tools and equipment, leading to time-consuming and labour-intensive processes. The UDT Leopard features a tool-free installation design that enables quick and efficient assembly, reducing downtime and improving operational efficiency on drilling sites.

• Compatibility: The UDT Leopard is designed to be compatible with existing casing pipe sizes and The configurations, allowing drilling companies to seamlessly integrate the new connector into their operations without the need for extensive modifications or retrofitting

Results of Using UDT-Leopard connectors

Use of UDT Leopard Multi-start  connector result in significant improvements in efficiency, reliability, and safety of operation Some of the key outcomes:

1. Reduced Down Time / Rig Time.

• From 08-10 Hours with traditional BTC Connection to 02-03 Hours with UDT Leopard Connectors.
• For Every 200 Metres lowing of Casing assembly 

1. Saving  operational cost upto 72%
2. UDT Supplied around 6000 metres of casing with UDT Leopard Connectors (Weld-on) meeting specific technical needs of the customer.
