The producers were established for a Second Eocene Water Injection Pilot (SEWIP) area that never completed the execution of water injection...

... Principal Field. The unconsolidated sands and high permeability of the reservoirs necessitate a robust casing design to withstand potential axial loads arising from thermal expansion during production and mechanical stresses encountered during drilling and completion operations ( Gonzalez et al., 2019...

.... Usually, the maximum interval length in CHGP completions for oil producers in this area ranges from 30 to 50 m, with leak-off managed by pumping high-rate sand control treatments. In the current scenario, CHGP completions for water-producer wells exceeded 120 m, which requires unusual methods to ensure...

The deployment of the first HWO unit for AON confirmed the ability to allow operations on locations with multiple constraints in terms of reduced site preparation requirements...

..., receiver, and communication processor, as well as an optical fiber integrated into the well completion. A double-ended fiber configuration is preferred, as it allows bi-directional laser pulses to improve measurement reliability and compensate for potential signal losses. Value of DTS in ACG DTS has...

... overcome by naturally restarting the field. However, recently with the increased water cut, a greater volume of water flooding into the oil-producing zones would make it impossible to reactivate the field without use of artificial lift systems. Installing any artificial lift means in a monobore completion...

... Abstract Deployment of Open Hole Multistage Fracturing (OH MSF) completion system in long horizontal wells has always been a daunting task, and often presents high risk of getting stuck in open hole due to complex completion design with very stiff assemblies that include multiple large OD...

Abstract This paper aims to present the best practices acquired in Ecuador, Orient Basin, from 2016 until 2023, during the completion of 25 horizontal wells with low reservoir formation pressure and an average of 1,000 feet of horizontal section. This analysis covers three main risks identified...

...) [1] . Nonetheless, GOM reservoirs have complex depositional settings. Reservoir heterogeneity, stacked pay system, reservoir compartmentalization, high-temp and pressure are some of the common challenges seen in these fields. The use of conventional completion design in vertical wells with commingled...

This paper aims to discuss & elaborate what has been done in each phase starting from planning phase for drilling and completion with inputs on subsurface matters throughout the phase of operation and contingency execution. The main focus...

In general, the cluster's oil fields...

...) this can result in loss of oil production. This challenge can potentially be addressed by implementing an advanced inflow control valve completion to suppress the gas-oil ratio (GOR) and maintain oil production. Uneven inflow in a horizontal oil well will usually occur due to a pressure drop in the liner...
