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.

D. buy generic viagra Biochemical and pathologic analyses of the intracystic nodules were conducted in two cases. generic viagra online Previous section next section results the results obtained from 13 patients with rathke's cleft cysts are presented in table 1. viagra online Clinical symptoms were observed in all patients. buy viagra These included headache in eight patients, visual disturbance in three, infertility in one, and seizure in one. buy cheap viagra All patients underwent trans-sphenoidal resection of the rathke's cleft cysts. buy viagra The diameters of the rathke's cleft cysts ranged from 5 ã— 5 to 18 ã— 10 mm. cheap generic viagra The location was intrasellar in seven patients and intrasellar and suprasellar in six patients. viagra for sale View this table: in this window in a new window clinical, mr imaging, and intraoperative findings in rathke's cleft cysts in 10 (77%) of the 13 patients with the rathke's cleft cysts, an intracystic nodule was identified on intraoperative-field and mr images. The nodules appeared high in signal intensity relative to white matter on t1-weighted images and low in signal intensity on t2-weighted images (fig 1). viagra vs viagra vs viagra questions Relative to the signal intensity of the nodules on the t1-weighted images, cyst fluid revealed low signal intensity in four cases and isointensity in the remaining six cases. Safe mix adderall viagra In all cases with intracystic nodules, the cyst fluid appeared to have isointensity to high signal intensity relative to the signal intensity of the nodules on the t2-weighted images. how to buy cheap viagra online Intracystic nodules were clearly visible on the t2-weighted images.

Patient 9. cheap viagra Rathke's cleft cyst with intracystic nodule. generic viagra soft tabs A, nodule (long arrow) in the cyst shows high signal intensity. Cystic fluid (small arrow) shows low signal intensity on axial t1-weighted image (600/25/2). cheap viagra B, high signal intensity of surrounding fluid (long arrow) and low signal intensity of intracystic nodule (small arrow) are well delineated on axial t2-weighted image (2300/120/2). Viagra for daily use 5 mg Surgery revealed that the nodules were yellow, waxy, solid masses. how to buy cheap viagra online Although pathologic findings of the intracystic nodules showed mucinous masses, the presence of cholesterol and protein was confirmed by biochemical analysis. Viagra bph medicare Surgery also revealed that the cystic fluid of rathke's cleft cyst was mucoid in 10 cases and serous in three. buy viagra online ehow Six of the cases with mucoid fluid had cysts with high signal intensity relative to white matter on t1-weighted images and variable intensity (two low and four high) on t2-weighted images. how to buy cheap viagra online The remaining four cases had isointensity to low signal intensity on t1-weighted images and high signal intensity on t2-weighted images. buying viagra online with a prescription Two cases with serous cystic fluid had high signal intensity on t1- and t2-weighted images. In another case with serous fluid, the cyst fluid was.
