| 1 | Root cause of sand production and methodologies for prediction显示文摘The consequences of sandstone reservoir rock failure may lead to sand production.This phenomenon can have negative impact on lifting cost and economic of any field development.Metal erosion due to sanding can lead to loss of integrity and hydrocarbon leakage.Poor decision on the type of completion can risk the viability of the field.To facilitate best sand management over the life of a field and to maintain economical productivity,accurate prediction of sand production volume/rates is needed to increase both productivity and the ultimate recovery of the hydrocarbon while keeping the operating cost low.This paper summarizes the sand production modeling for onset and volume of sand namely technology that required to improve understanding on sand production and mitigation.Three main questions will be answered,why industry needs to worry about sand production,what are the available technologies to predict sanding volume/rates finally,how the current technologies can be improved to estimate sand production volume/rates. | Surej Kumar Subbiah Arifin Samsuri Assef Mohamad-Hussein Mohd Zaidi Jaafar Ying Ru Chen Rajeev Ranjan Kumar | 2021 | Petroleum2021，7，3： | 0 |
| 2 | Geomechanical modelling of cold heavy oil production with sand显示文摘The contribution of geomechanics to provide a rigorous quantification of porosity changes and associated permeability changes is often neglected when considering hydrocarbon production.However,it often has significant effects on production rates and ultimate recovery.For the cold heavy oil production with sand(CHOPS)technique,geomechanics is the key for reservoir simulations and promoting successful operations.In fact,the technique employed in CHOPS significantly affects the stress state within the reservoir by inducing“on-purpose”formation damage.It is not only vital to comprehend the behaviour of the reservoir during production,but it is crucial to identify how to harness that behaviour to improve productivity.In order to simulate the mechanical behaviour of unconsolidated sand material,an elastoplastic damage model was formulated.Fluid-flow-geomechanical modelling was then performed for predicting individual well behaviour and overall field performance.The combined effect of fluid-flow and geomechanics improved predictions with respect to oil,water,and gas production rates at key wells.Fluid rates matched satisfactorily most of the wells.In addition,the onset and propagation of equivalent wormhole networks were quantified throughout the production history.This enabled quantification of the volume of produced sand at individual wells.The comparisons between the measured and simulated sand volume rate at well locations showed reasonable agreement.Such calibrated models can then be used for the placement of new wells to optimize production. | Assef Mohamad-Hussein Pablo Enrique Vargas Mendoza Paolo Francesco Delbosco Claudia Sorgi Vincenzo De Gennaro Surej Kumar Subbiah Qinglai Ni Jose Maria Segura Serra MRLakshmikantha Jos Alvarellos Iglesias Rebecca Daniels | 2022 | Petroleum2022，8，1： | 0 |
