in reservoirs that have never produced hydrocarbons may require a relatively high drawdown pressure facilitating high drawdown pressures may require in turn the use of surface or downhole lift or pumping systems that are not compatible with solids production for example excessive solids may clog or damage electrical submersible pumps testing formations for solids production often is omitted or avoided in many well appraisal programs which is undesirable one advantage of the testing apparatus and method of this invention is that many of the uncertainties of sanding test design may be avoided by allowing lift or pump systems to apply high drawdown pressures directly to the subterranean formation allowing for subsequent collection of a representative sample of the produced solids for analysis in fig1 an apparatus 20 is shown suspended from a hanger or packer 21 a ported tubular housing 23 comprises a proximal end 22 and a distal end 24 entry ports 26 28 as examples are provided through the housing which provides an entry point for formation fluid and sand several entry ports in addition to entry ports 26 28 may be provided for fluid entry into the apparatus 20 depending upon the configuration of the apparatus 20 an attachment mechanism 30 is provided for secure and releasable connection of.
