degradation of the degradable sleeve 516 spotting acid at this point and location may also focus the process of extending the jet flow path from the jet forming apertures 504 radially outward from the housing 502 at least to a distance equal to the width w of the sleeve 516 in a further embodiment wherein the sleeve 516 is made of metal such as aluminum or another more robust material an acid may be flowed into the jet flow path 530 to melt or otherwise degrade the sleeve while the assembly 500 is in the open position in additional embodiments wherein the sleeve 516 is degradable the degradation of the sleeve 516 may create an acid such as lactic acid or other erosive material which then begins to degrade the cement degradation of the cement beyond the sleeve 516 assists in further extending the jet flow path generally in the area 522 of the cement formation 520 which is created from a cement slurry applied in the usual manner in still further embodiments the jet forming apertures 504 may be filled with a degradable substance or removable member in one embodiment the apertures 504 are filled with a plug made of the same material as the degradable sleeve 516 such as pla a pla plug may simply be a portion of pla in the shape of a plug that is adapted to be inserted into an aperture 504 in another embodiment the apertures 504 are filled with a gel that can be degraded as disclosed herein or may be pushed out of the apertures 504 with fluid pressure it yet another.
