... pressure buildup tests were analyzed using three pseudopressure techniques for comparison: the single-phase pseudopressure, the two-phase steady-state pseudopressure and the two-phase three-zone pseudopressure. Results indicated that all three pseudopressure techniques were capable of estimating...

... by the following relationships in SI units: (1) A = | Δ P Δ q | (2) k   h = μ 8 A | sin ( φ ) | Abstract One of the predicaments of traditional well testing is the requirement of shutting-in a well to conduct a pressure buildup test for the purpose...

... with a pressure buildup test done at the end of this flow period. A downhole shut-in configuration significantly reduced the duration of wellbore storage during the buildup test, allowing detailed characterization of the fracture and surrounding reservoir rock. The derived S FS from pressure buildup analysis...

... Abstract This paper presents a semi-analytical wellbore/reservoir model 1 that can describe general wellbore effects, especially the thermal effect, on high temperature gas well pressure buildup tests. A numerical simulator has been developed from the model. Using different combinations...

... of the drilling and completion strategy was demonstrated using pressure buildup tests to measure skin. Inexpensive pressure buildup tests were conducted prior to field startup, using in- house personnel and equipment, in addition to more conventional testing after field startup. Development well skins were...

... rates with the onset of water breakthrough. Pressure buildup tests were run in an attempt to identify the cause of the production decline. Qualitative analysis of the signature of buildup tests was used to identify the most likely reservoir description that would produce similarresults. That reservoir...

.... In general, most operating companies do not spend the money nor the time to gather and analyze the data needed to properly characterize the hydraulic fracture. Occasionally, an operating company will run a post-fracture pressure buildup test. However, if that test is not run long post-fracture pressure...
