AIFE American Institute of Formation Evaluation





        AIFE, The American Institute of Formation Evaluation LLC. is the world leader in Computerized Drill Stem Test collection and analysis.  AIFE has been collecting and analyzing DST information for the past twenty years.  Our skilled personnel have processed and computerized over 436,000 individual Drill Stem Tests worldwide.  AIFE's United States Drill Stem Test Library (USDST), presently contains over 170,000 individually analyzed DST's covering the Rocky Mountain and Mid-continent regions of the United States and provides the most comprehensive computerized data bank of DST information available to the American Petroleum Industry.

        In an effort to obtain such extensive basinal coverage of DST's in all regions of the United States AIFE has been actively collecting both public and previously unavailable data from a vast array of sources.  To further augment data collected directly by AIFE, and to help provide the current basinal coverage, data from private sources and major exploration companies have also been individually analyzed and computerized.  USDST contains DST's that have been run over the past 40 years and provides the most accessible pressure database of its kind in the United States.

       Our experienced personnel have evaluated each DST as taken from the original service report, using consistent classification and codification methodologies to ensure not only quality but accuracy of interpretation.  Where applicable, each DST is digitized to allow for shut in analysis.  Horner extrapolations and slopes are calculated and used in the classification of the individual DST to provide the most usable DST information for regional or basinal analysis.

Howed asymmetrical cortical hypoperfusion in the perirolandic area, supporting the importance of dysfunction of this area to lka, and the patient with constructional apraxia had unilateral hypoperfusion in the left posterior parietal area. generic viagra safe india Buy viagra 100mg online In an attempt to further refine our understanding of the neural networks involved in ima in cbd, attempts to correlate 18fdg positron emission tomography data with a cognitive neuropsychiatric assessment of apraxia have been made. viagra online Viagra 100mg price costco In one such study that evaluated 18 patients with cbd, two complementary measures of apraxia were used. buy viagra online 20 year old need viagra First, a performance score measured error frequency during gesture execution and, second, a correction score measured the patient's ability to correct initial errors on a second attempt. Can i buy viagra in uk viagra without a doctor prescription The authors found that anterior cingulate hypometabolism predominated in patients with cbd who performed below the cutoff performance score for apraxia (14/18) and that in those (7 out of 18) who could not correct their errors (which occurred mainly in gesture imitation), hypometabolism in the contralateral superior parietal lobe and supplementary motor area predominated, although there was also a deficit noted in the ipsilateral precentral gyrus (peigneux et al. viagra for sale cheap generic viagra , 2001). generic viagra canada Other techniques that have been used to examine the central mechanisms underlying limb apraxia in cbd include somatosensory evoked potentials and transcranial magnetic stimulation. cheap viagra online For example, somatosensory evoked potentials in five patients with cbd have been compared with those in 12 controls (okuda et al. viagra online eu , 1998). long does pill viagra last This study found that all patients with limb apraxia, particularly lka, had prolonged n20 latencies following median nerve stimulation on the more apraxic side, suggesting that somatosensory information processing involving the parietal cortex might be involved. which is best viagra viagra or viagra The problem with all these studies is not only that most of the cases assessed were clinically diagnosed, and not autopsy confirmed, but also, and more importantly for the purposes of this discussion, that most patients studied had other deficits, including dystonia, rigidity and cortical sensory loss. which is best viagra viagra or viagra Furthermore, many of the functional imaging studies were done in the resting state, and not while undergoing tests of praxis. best canadian pharmacy generic viagra Thus, it is impossible to be certain about the relationship between the metabolic or electrophysiological findings and the presence of apraxia. buy cheap viagra Previous section ne. cheap viagra online discount generic viagra mg
