This report summarizes three areas of work in support of gas well stimulation. First, a topical report has been written that documents the mechanisms and impact of formation damage following hydraulic fracturing. The categories of damage are reviewed including matrix permeability damage, relative permeability damage, the plugging of natural fractures and conductivity impairment. Remedial treatments and their effectiveness are also reviewed. A survey of procedures and service companies was conducted to identify perceptions and technical hurdles regarding formation damage. The second area involves the completion and beta testing of relational databases to store well, completion, production and lab testing information. The databases are known as COAL`s (Coalbed Methane Information System), DRAGOR (Drilled Resources Analysis of Gas and Oil Recovery) and STIM-REC (Stimulation Record Catalogue). Finally, a proof of concept task was undertaken to look at the feasibility of manufacturing a drag force device to measure low shear viscosity of frac fluids on location. The device would predict the proppant transport character of fracturing fluids.
