... brine salinity and flow rate affect repulsion and hydrodynamic forces. Accurate CSC and critical flow rate prediction are crucial to prevent formation damage. This research presents a novel DLVO modeling approach for predicting and controlling fines migration in sandstone reservoirs. DLVO models...

... the downhole safety valve and Christmas tree valves. This study is expected to be a good tool in recommending scale inhibition methods or products for new wells drilled in October field or any analogous field. This study can compensate for the gap between commercial scale prediction software and actual scale...

... Abstract Being able to predict formation damage due to near-wellbore scale deposition relies on accurate scale prediction modelling. It is recognised that the relative paucity of HPHT solubility data can result in inaccurate predictions, as current models typically extrapolate from solubility...

... Abstract This paper investigates field-scale predictions of engineered water injection (EWI) technology in the secondary and tertiary injection modes. Three synthetic 5-spot reservoir models were considered: homogeneous reservoir, heterogeneous reservoir with permeability channeling...

...) vugs or caverns. This study provides an integrated workflow to predict expected losses for such classification/mechanism of losses. Mud loss through fracturing is categorized based on fracture types, i.e., natural or induced fractures. Different models are used with respect to the fluid-loss mechanism...

.... The experimental coefficients were used as the primary input into a well injectivity model. The proper estimation on the filtration enabled us to analyze the impact of injection rates and proppant selection on injector performance, i.e., predict longterm injection well behavior. The effect of particle filtration...

... examined the mechanical properties, including rock strength and plasticity, as well as the state of stress acting on the producing sections. The study predicted the sanding history of both wells accurately. Modelling indicated that a thin sand layer with low rock strength was the main contributor...

... to predict the critical sand deposition velocity in order to maximize reservoir production. Gas-liquid-sand flow hydrodynamics, which is commonly encountered in most reservoirs and also in oil and gas transportation pipelines, is more complex than liquid-sand flow, making the modeling extremely difficult...

One of the key identifier of the subsurface model is accurately predicting the hydraulic flow units. There are several models currently used in the prediction of these units based on the type of the data...

This paper describes recent research directed at improving the accuracy of penetration prediction at downhole conditions. Most conventional industry penetration models are based on laboratory experiments spanning the 1960...

... In this work we consider five different patterns: dispersed bubble, bubble, slug, churn and annular then we present models for prediction of pressure drop in bubbly and slug (churn) flow regime. The work by Taitel et al. was used to predict the flow pattern, with modified bubble to slug...

... Abstract A novel concept for cleanup prediction during sampling is proposed. This concept shifts focus to the early phase of cleanup, allowing for early predictions of pumpout time or produced volume using optical fluid analysis logs versus given contamination targets. The early phase...

Selection of separators and reserve tanks for UBD involves using a method to predict reservoir fluid inflow rate and volume. Such a method...

... Abstract A detailed sand prediction has been made for three wells at Chevron's West Seno field based on logs/lab data and the results have been calibrated with production data. Both maximum allowable drawdown and depletion increase with depth. Additionally, oriented perforations offer...

... Abstract The X-1 well in a gas field in Trinidad was designed to be a high-rate gas producer from a 65° deviated well through the S1U, S1L and S2U sands at ~9200 ft TVD. After a pre-drill sand prediction, the well was cased and perforated without sand control, but the perforations were oriented...

... production in weakly consolidated formations is generally assumed to be a two-step process, with the shear failure being the first step and the transport of the sand out of the perforations and up to the surface being the second step. Existing sand production prediction models have focused on predicting...
