Castex Offshore had a successful flow testing of its Main Pass Hummer discovery well, offshore Louisiana, according to partner Petsec Energy.
Flow rates were measured at restricted rates on variable choke sizes over the last three hours of the 48-hour test period the well flowed at an average rate of 19.88 MMcf/d and 396 b/d of condensate through a 16/64in choke with an average flowing WHP of 9753 psi and no formation water. Production rates continued to rise over the duration of the test with a maximum gas rate of 20.5 MMcf/d recorded.
The MP 270 #3 BP 01 well was perforated from14,100ft to 14,186ft measured depth (MD), 14,058-14,144ft true vertical depth (TVD) in a Miocene age sand reservoir. Well logs indicate additional potential reservoirs in the well, but a decision was made not to run additional tests at this time. These untested sands will be targets of future drilling activity on the Hummer Project. Significant production occurs for similar reservoirs along trend. Peak production rates from those intervals can exceed 25 MMcf/d and 1000 b/d. After testing, the well will be temporarily suspended pending the design, fabrication and installation of permanent production facilities and pipelines. The company estimates first production from the Hummer project to commence mid-year 2017.
The Hummer discovery well is located in US federal waters about 50mi southeast of Venice, Louisiana. The water depth at the location is some 215ft. The well was drilled, logged and temporarily suspended during Q3/Q4 2015 and has awaited testing until a recently completed production jacket could be installed over the well. The Ensco 87 rig was used to tie-back the well bore to the jacket and complete and test the well. The next stage of development will be to utilize the results of the test to design, fabricate and install a deck section with production facilities on the jacket, lay flow lines and connect to existing oil and gas transportation systems. It is anticipated that this process will take approximately six to eight months.
“Hummer is a significant oil and gas discovery covering a large prospective area and extending over portions of three offshore lease blocks that will require additional wells and facilities to define and develop,” Petsec Chairman and Managing Director Terry Fern said.
