Subject:        Revival of Production - Jand-1 Well

Dear Sir,

We are pleased to inform that Oil & Gas Development Company Limited (OGDCL) has successfully revived gas production from Jand-1 well, located in Attock District, Punjab, marking a notable operational achievement.

Following recompletion and targeted stimulation, Jand-1 well is currently producing over 21 MMSCFD of gas through a 32/64" choke at wellhead flowing pressure (WHFP) of 3,585 psi, representing a substantial increase over its previous production level of around 7.0 MMSCFD.

The well was initially brought on production in 2019 through Dakhni Gas Processing Plant and was producing gas with a high H₂S concentration of approximately 8% (~80,000 ppm). Subsequently, production ceased due to mechanical failure under challenging downhole conditions associated with the sour gas environment.

Based on in-house technical assessments and risk analysis, OGDCL successfully executed the revival plan through its own technical team and deployed equipment. The operation included safe retrieval of downhole materials and restoration of well integrity under challenging conditions. The operations were carried out in accordance with stringent health, safety, and environmental standards. The well has been recompleted with corrosion-resistant tubing suitable for sour service to ensure safe and sustained operations.

This development reflects OGDCL's continued focus on optimizing existing assets through technical expertise and effective resource utilization, contributing to enhanced domestic hydrocarbon supply.

The above information is being submitted in compliance with Section 96 of the Securities Act, 2015 and Clause 5.6.1(a) of the PSX Regulations for dissemination among your members.

Yours Sincerely,

(Wasim Ahmad)

Company Secretary
