... on the application and challenges of the seismic monitoring. Egina 4D M1 Ocean bottom Nodes (OBN) seismic data, which was acquired in October 2021, provided valuable insights into the reservoir dynamics including injected & aquifer water movement, pressure evolution in the vicinity of water injectors...

... it from escaping. There are two types of wells used for extracting oil: injector wells and producer wells. It is possible to push the oil towards the producing well ( Figure 1 – (d) ) with the help of a gas injector well ( Figure 1 – (b) ) and a water injector well ( Figure 1 – (c) ). Flowing gases push...

... and injectors while also minimizing process safety risk on all wells. These wells are referred to as top tier wells. This paper defines criteria for selecting top tier wells. It also focuses on using a Prevent-Detect- Respond-Recover (PDRR) approach in defining a well equipment PM program that meets industry...

... on estimated reservoir quality index (RQI) and permeability capacity (kh × Net/Gross Ratio)as shown in Figure 1 , and Table 1 . Abstract A water injector pilot well - Ughelli East-30, was drilled across high-permeability unconsolidated sandstone aquifers to dispose 30 Mbwpd of produced water...

... the trunk line for the sale of their crude. But because of the use of wide range of non-compliant meters by the injectors into the trunk lines a lot of line losses due to measurement errors are introduced. Another major feature is that trunk lines are exposed to leakages due to sabotage, aged pipeline...

... of the reservoir that had become inactive due to low tubing head pressures with reservoir pressure depletion. The identification of an optimal water injector location to improve the low reservoir energy and sweep oil towards the existing producers was grossly challenged due to remote nature of existing wells from...

... to stratigraphic compartmentalization and poor positioning of the injector as the main culprit. Three (3) scenarios were tested, considering the geologic complexity of the reservoir. Scenario 3 shows a recovery factor of 48.1% and a recoverable volume of about 25.4MMSTB and was adjudged the best development...

... storage between injectors and producers in a reservoir. The CRM has been applied to waterflood management and performance prediction, improved reservoir characterisation, waterflood optimisation and, production optimisation. In this study, the CRM was used in fault characterisation and flow barrier...

... For a typical CRMP analysis, a reasonable random pattern on any number of injectors (N i ) and producers (N p ) is considered in a control volume space as in Figure 1 below. Sayapour et al (2007 ) in their paper showed the governing differential equation as: (1) d q j ( t...

Reservoir_A, with one producer (Well_1) and one injector (INJ_1); and Reservoir_B, with one producer (Well_2), are on production. As part of the characterization...

... certainty about reservoir connectivity. It was assumed in the initial FDP that two producers located around the top structure would be supported by two injector wells located on the flanks near the HWC. In 2011, the first producer ( Akpo-XP ) was completed in the three units and equipped with an inflow...

.... This study aims to present an original methodology to analyse the performance of water injectors in a deepwater turbidite field and evaluate the evolution of their injectivity over time. An injectivity monitoring tool was developed by incorporating injection flowrate and pressure data with the following...

... Abstract The AX field is located in Deepwater Offshore Nigeria and has been in production for ca.12 years through FPSO with a waterflood scheme providing pressure maintenance and sweep for the reservoirs. Over the years, AX field has moved from the use of deviated frac-pack injectors...
