... well integrity risks in the field, which implies the need for proper zonal isolation throughout the well and the field lifespan. These formations also comprise a low formation frac gradient, that raises the requirement for low-density cement ranging from 8.5 to 10.5 PPG to overcome the shallow loss...

... Abstract The recovery from fractured reservoirs is usually low. The areal heterogeneity is one result of the fractured reservoir. Low salinity waterflooding (LSWF) and preformed particle gel (PPG) have recently drawn great interest from the oil industry. LSWF can only increase displacement...

.... Eventually a new, Wellbore Pressure Containment Improvement System (WPCIS) was implemented, and it controlled the losses effectively. The well had been losing at an ECD (equivalent circulating density) of 16.4 ppg. Application of the WPCIS process improved the wellbore pressure containment (WPC) side...

... Cementing First Stage After setting the first stage cement slurry, and with 10.7 ppg drilling fluid above the cement column, the net hydrostatic pressure gradient exerted at bottom, typically reaches to as high as 0.65 psi /ft, thus, exceeding reservoir fracture gradient and inducing losses Losses...

.... In order to control the fluid within such layer, mud weight, in excess of 19.0 ppg is required. Below this section is a slight pressure reversal which includes fractured carbonates. Due to such pressure differences between layers and the position of lost circulation layers within productive zones, numerous...
