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.

Th a simple manometer. viagra samples free online A graduated glass tube is attached to the lumbar puncture needle and the height in mm to which the fluid ascends in the tube is measured. generic sales viagra The normal csf pressure in adults is 60 to one hundred fifty mm of fluid and 45 to 90 mm in children. Pathological variations of pressure â â â â â â â â â â â â â â â â â â  abnormally high pressure is found in icsol,haemorrhage,hypertensive encephalopathy,hypervitainosisa,hydrocephalus,â intracranial sinus thrombosis,meningism,some forms of meningitis,encephalitis,uremia,corpulmonale. buy cheap viagra online â â â â â â â â â â â â â â â â â â  subnormal pressure is seen in :â  head injury,dehydration,spinal subarachnoid block, â â â â â â â â â â â â â â â â â â  abnormally low :â  second lp is performed shortly after previous one. online to buy viagra or cialis Queckenstedt’s test normally if one compresses the jugular veins during lumbar puncture,there is an immediate and rapid rise in csf pressure and rapidly falls to normal when compression ceases. compare viagra viagra en viagra Venous compression causes raised pressure in the intracranial venous sinuses and hence in the cranium. lowest price on generic viagra This test is used to check the patency of the subarachnoid space between the cranial cavity and the lumbar sac. buying generic viagra Csf examination. compare viagra viagra en viagra Csf may be obtained by lumbar,cisternal or lateral cervical puncture or through ventricular cannulas or shunts. viagra 20 mg fiatı A manometer is attached before any fluid is removed to record the opening pressure. is generic viagra safe A dramatic pressure droop of 1 to 2 ml suggests herniation or spinal block above the puncture site. Viagra viagra annual sales No further fluid should be withdrawn in this situation. retail price of viagra Upto 20ml of spinal fluid may be removed normally. discount generic viagra Indications for lumbar puncture can be divided into four major disease catogories. online pharmacy generic viagra Ie 1)â â â  meningeal infection 2)â â  subarachnoid hemorrhage 3)â â  cns malignancy 4)â â  demyelinating diseases identification of infectious meningitis,esp bacterial is the most important indication of csf examination. compare viagra viagra en viagra The potential yield of csf examination in diseases should be weighed against the small risk of potentially serious complications of lp.

What insurance plans cover viagra cheap mg viagra pills fast deliervery        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.
