Abstract

Resin coated proppant is used in hydraulic fracturing applications to stimulate oil/gas wells for production enhancement. The objective of this study was to perform a rock mechanical study to evaluate long term stability of RCP combined with various additives currently being used in screenless propped hydraulic fracturing completions in the sandstone formations to provide a tool for the industry to know exactly the duration of the shut-in time before putting well back in production. A new experimental method was developed to monitor the curing process of resin-coated proppant as temperature increases. The velocity of both shear and compressional waves were being monitored as a function of temperature. The tested resin of coated proppant sample has been housed in a pressurized vessel. The pressurized vessel was subjected to varying temperature profiles to mimic the recovery of reservoir temperature following propped hydraulic fracturing treatment. The placed proppant should attain an optimum consolidation to minimize proppant flow back.

Introduction

Historically, sand production from poorly consolidated and unconsolidated sand formation, is a serious problem. These problems can lead to lost reservoir productivity, increased rates of required workover expenditure, fines plugging gravel packs, screens, perforations, tubulars and surface flow lines or separators. These problems hamper hydrocarbon production.
