...Step 1 – Parameterization The first step in assisted history matching involves a translation of the identified subsurface uncertainties into model parameters that can be varied over given ranges. This is usually referred to as parameterization. Uncertainties can be parameterized in a variety...

... petrophysical interpretation : This is one of the major challenges met during the history matching process caused by the nature of the formation water properties (fresh-water salinity). Sustainability of oil producers : Most of the producer wells produce by intermittence. To address the water...

... history match with all the extra inputs and forecast; and optimizing the development with all the input parameters within a short timeframe is always a challenge. The process employed in this approach was based on deep learning artificial neural networks (ANN) coupled with numerical simulators and along...

... Abstract The identification of the fluid fill history is a necessity for the development strategy of any field, in particular in the Middle East where tectonic history is often reported to affect fluid distribution and contacts in many fields. The fluid fill concept for a low permeability...

... analyses were performed using the full field data-driven model; complementing the existing conventional numerical model. The accomplishments of the data-driven reservoir model for this project included, but not limited to, comprehensive history matching (including blind validation) and then forecast of Oil...

... investigation of the various approaches was conducted in Fahimuddin et al. (2010) examining different kinds of seismic data for history matching with the Ensemble Kalman Filter. They concluded that time-difference impedance data performed better than time-difference amplitude data. The former approach...

... decline and increasing gas/oil ratio (GOR) and water production. To achieve a fully integrated history matched model, the first step was to make a thorough review of the existing detailed seismic interpretation, vintage production logging tool runs (PLT's), wireline logs (including borehole image logs...

... Abstract We demonstrate how key geological uncertainties in a giant onshore carbonate reservoir in the Middle East, most notably fracture permeability and saturation distribution, impact the quality of the history match and change the performance forecasts of a planned Miscible Water...

.... Palynomorphs are usually rare in the redbeds of Hospital Ground and palynostratigraphy is therefore of limited use. Intra-Maurits seismic reflectors offer further constraints. The structural configuration of the Carboniferous in the CBH area is the result of a complex history of superimposed tectonic...

..., and therefore in need for redevelopment to increase its recovery factor. However, despite the long production history, subsurface uncertainties remain high due to its reservoirs complexity and limited reservoir data. To assess the subsurface uncertainties and their impact on field redevelopment plan, a fine...

The mainobjective of this work is aimed at proposing an accurate and fast method to implicitly and inversely determine the three-phase relative permeabilities of WAG processes. This method uses history matching techniques which...

After history matching with initial phase of production, current reservoir pressure and saturation will be determined as inputs to time-lapse geomechnics model...

... To meet this aim the paper is structured as follows. First, some general information is provided on the Wara-Burgan reservoir, fluid system, production history, previous studies and ongoing development plans. Some of the difficulties associated with modelling the Wara-Burgan reservoir...

... Abstract Power of ensemble based data assimilation methods to history match oil and gas reservoirs has been revealed during the past couple of years by different field application works ( Oliver and Chen, 2011 ). Moreover the achievements in advanced parameterization ( Lorentzen et al. 2011...
