At later stages post production, the uncertainties shifted to refining the connected volumetric reserve, aquifer strength related to water production, and sand bursts problem that is limiting maximum well production. Abstract Managing big gas well requires...

... of the cement job has a significant impact on the well productivity, especially because the guns are left downhole, which severely limits remedial options. Given the high importance and difficult conditions of the cement placement, a process of continual review was established with the idea of incorporating...

... using 20% HCl and with pulsonix tool for acid placement. Initial well productivity (PI) was estimated at 0.16 STB/D/psi. Post stimulation treatment resulted in a nine-fold PI improvement. Production post stimulation was 720 barrels oil per day (bopd) with 7% water cut (w.c). The NWB stimulation enabled...

This paper describes steps taken in evaluating the root causes of the decline in well productivity. Research and screening mitigation options are also...

..., further lowering the FTHP, a lower abandonment pressure was obtained and consequently reserves recovery increased through well life extension. In 2008, VICO installed 19 wellhead compressors, achieving FTHP’s as low as 5 psi. This resulted in increased productivity, individual well production stability...
