Figure 11. Case study: Data-dense Middle East Thamama B or Kharaib-2. (A) Prediction scores of sedimentary facies into the log domain with an average score of 47%. Codes for the sedimentary classification are provided by Strohmenger et al. (2004, 2006). (B) Further lumping or grouping results in “better than 80%” scores for two groups which represent dense argillaceous and reservoir prone sedimentary facies. (C) Electrofacies generation produced six electrofacies association categories, one of which equals the dense argillaceous lithofacies association category 1 (FAC-1) and the other five contained within the reservoir-prone FAC-2. discussion. ASFB = algal, skeletal floatstone-boundstone; ASPF = algal, skeletal, peloid floatstone-rudstone; BBOSP = burrowed, bioturbated, orbitolinid, skeletal packstone; BBOSW = burrowed, bioturbated, orbitolinid, skeletal wackestone; BBSP = burrowed, bioturbated, skeletal packstone; BBSW = burrowed, bioturbated, skeletal wackestone–mudstone; CgASR = coated-grain, algal, skeletal rudstone-floatstone; CgSG = coated grain, skeletal grainstone; OSP = orbitolinid, skeletal packstone; OSW = floatstone; PRC = petrophysical rock category; RPF = rudist, peloid floatstone; RPR = rudist, peloid rudstone; SPG = skeletal, peloid grainstone; SPP = skeletal, peloid packstone; SPWP = skeletal peloid wackestone-packstone; SW = skeletal wackestone; WBOSP = wispy-laminated, burrowed, orbitolinid, skeletal packstone; WBOSW = wispy-laminated, burrowed, orbitolinid, skeletal wackestone; WBSP = wispy-laminated, burrowed, skeletal packstone; WBSW = wispy-laminated, burrowed, skeletal wackestone-mudstone.
