OGDC Completes Chak 63-05 Development Well in Sanghar, Expanding Sindh Production Base
OGDC has successfully drilled and completed the Chak 63-05 development well in Sanghar district, Sindh, adding another production asset to its portfolio as the company continues its infill drilling campaign in the Indus basin.
Chak 63-05: Development Well in Sanghar
OGDC has successfully completed the Chak 63-05 development well in Sanghar district, Sindh. Sanghar is a well-established hydrocarbon district within the Lower Indus basin where OGDC operates multiple concessions. A development well completion -- the stage at which drilling, casing, and perforation are finished -- precedes first gas or oil flow testing, which will determine the commercial production rate the well will contribute once fully commissioned.
Significance of Infill Drilling
Chak 63-05 is designated with an infill numbering convention, indicating it is drilled within the boundaries of an existing producing reservoir. Infill development wells are among the lowest-risk capital deployments for an E&P company: the geological risk is minimal because the reservoir is already proven, the infrastructure to connect the well is typically nearby, and the drilling programme is standardised. For OGDC, completing development wells in Sanghar is part of a broader programme to sustain and grow production from its Indus basin assets as natural field decline is offset by new well additions.
Production Outlook
Once a completed development well moves through well testing and tie-in to the gathering pipeline, its production is typically metered into OGDC's daily output figures within weeks of completion. Investors tracking OGDC's quarterly production volumes can expect Chak 63-05's contribution to appear in upcoming production data. Combined with other recent well commissioning events in Sindh, OGDC's infill drilling programme is providing incremental volume support to its overall gas output.

Frequently asked questions
What is the difference between a completed development well and a well that is online?
Completion means the well has been drilled to target depth, the casing has been set, and the productive formation has been perforated to allow hydrocarbons to flow. Coming online means the well is connected to the gathering pipeline and production is flowing and measured. There is typically a gap of days to weeks between these two milestones.
Where is Sanghar district in Pakistan's hydrocarbon landscape?
Sanghar is located in Sindh province, within the Lower Indus basin -- one of Pakistan's most prolific hydrocarbon-producing regions. The district hosts numerous OGDC and PPL concessions that have been producing for decades. Its geology is well-understood, making development drilling here predictable and commercially reliable compared to frontier areas.
