Abstract

Abstract

The P.D.M Oilfield, located in Venezuela, is an oilfield of light crude with associated natural gas put into production in 1980. Geologic conditions in this oilfield are very complex. Wells with five intervals were designed for the development of the oilfield. Oil base drilling fluid was used to drill the fifth interval. The ϕ165.1 mm borehole section was cased with ϕ139.7 mm liners to about 5 200 m to seal off the coarse sandstone reservoir in Merecure formation (Oligocene series). After long time of development, the P.D.M oilfield is approaching depletion, daily production rate of a single well is less than 60 m³. Reservoir depletion has resulted in formation pressure depletion and hence lost circulation during drilling, and risks in well cementing. In well cementing operations, multi-function compound prepad fluids had to be used. Furthermore, H₂S existed in the associated natural gas. To deal with these problems, low density cement slurry was used to reduce the pressure in annulus exerted by fluid column, thereby to minimize the risks of lost circulation. High performance cement slurry with high toughness was selected for well cementing. The cement slurry had low filter loss, good mobility, transit time of gel strength less than 25 min, and the ability to minimize gas channeling in annular space. With the optimized cement slurry and operational techniques, liners in wells with low pressure, high seepage rates and narrow annular clearance have been successfully cemented.
- Narrow annular clearance,
- Low pressure,
- High seepage rate,
- Liner string,
- Prepad fluid,
- Cement slurry
