... of the ESP system. When designing an ESP to handle gas production, an operator will commonly incorporate an integral joint gas separator into the ESP design that mechanically generates the centrifugal force necessary to separate free gas from the fluid stream and evacuate it up the annulus. In...

Paper Number: SPE-164521-MS
... Wellbore instability and large wellbore breakouts/washouts are common problems encountered during drilling of tight sand formations, where significant stress anisotropy prevails. The breakouts in wellbore cause the well productivity to be reduced in the case of cased-hole perforated completion...

Paper Number: SPE-142283-MS
... Abstract Tight gas reservoirs normally have production problems due to very low matrix permeability and significant damage during well drilling, completion, stimulation and production. Therefore, they might not flow gas at optimum rates without advanced production improvement techniques. The...

... Abstract Use of horizontal and multilateral wells for oil and gas recovery has become a common practice in the petroleum industry. It is generally recognized that most horizontal wells do not produce oil and gas at the expected production rate. The discrepancy is mainly due to the fact that it...
