... Abstract The objective of the study was to evaluate the impact of different wellbore types on the effective retrieval of condensates in a gas condensate reservoir. Two reservoir models were built using CMG (Computer Modelling Group) and IMEX reservoir simulation models. These models had similar...

... Abstract The Joint Venture ("JV") Offshore Asset of company X in Nigeria hosts a portfolio of more than 600 wellbores. The asset is over 55 years old and as such, has a sizable number of idle wellbores. The Asset Team has been actively intervening in these idle wellbores using non-rig workover...

This would result in high bottom hole injection pressure (BHIP), diminished or loss of injectivity, screen plugging and erosion of downhole equipment which...

.... The lateral section of the wellbore, drilled with a 6" Rotary Steerable [RSS] BHA, was geo-steered to achieve the target inclination of 89.89degrees, positioning the wellbore optimally for oil recovery. Upon circulating the hole clean and making a short trip to the 7" casing shoe, the 6" RSS BHA was tripped...

This study focuses on the evaluation of the effect of tool-joint on the buckling of drillstrings for highly deviated wells. Tool-joint in pipes changes the pipes geometry in the wellbore thus...

... Abstract The most common challenge in horizontal drilling is depth uncertainty which can be due to poor seismic data or interpretation. It is arguable that a successful landing of the wellbore in the reservoir optimally and within the desired zone is the most challenging in most geosteering...

A localised region of high condensate saturation will occur close to the wellbore when the bottom-hole flowing pressure (Pwf) drops below the dew point pressure (Pd). A consequential reduction in gas...
