The Oil And Gas Operator Apache Announced That It Made A Significant Oil Discovery At The Maka Central-1 Well, Drilled Off The Coast Of Suriname, In Block 58
The oil well was drilled using the drillship Noble Sam Croft, with Apache as the operator holding a 50% working interest and Total with a 50% stake, Apache said on Tuesday. It is worth noting that Total made an agreement to acquire a 50% interest and operation in Block 58 in Suriname last December. It was agreed that Apache would operate the first three exploration wells in the block, including the Maka Central-1 well, and would subsequently transfer the operation to Total.

According to Apache’s update on Tuesday, the Maka Central-1 successfully tested for the presence of hydrocarbons in several Campanian and Santonian targets older than the Cretaceous, and found condensates of oil and gas. The formation evaluation program included profiling logs during drilling, wireline formation pressures, and preliminary core and fluid analysis. Along with future appraisal wells, this data will be used to quantify the resource in the Campania and Santonia formations.
The shallow Campanian interval contains 50 meters (164 feet) of liquid reservoir containing hydrocarbons. Preliminary fluid samples and test results indicate light oil and gas condensate with API gravities between 40 and 60 degrees.

The deeper Santonian interval contains 73 meters (240 feet) of liquid reservoir containing oil. Preliminary fluid samples and test results indicate API oil gravities between 35 and 45 degrees.
The Maka Central-1 also targeted a third interval, the Turonian, a geological analogue to the oil discoveries off the west coast of Africa. Before reaching this interval, the well encountered significantly pressure-charged reservoirs in the lower Santonian, and the decision was made to complete the drilling at approximately 6,300 meters (20,670 feet). The pressures encountered in the lower Santonian are a positive sign for the Turonian, and future drilling will test this interval.
John J. Christmann, CEO And President Of Apache, Said: “We Are Very Pleased With The Results Of Maka Central-1. The Well Confirms A Working Hydrocarbon System In The First Two Play Types Of Block 58 And Confirms Our Geological Model With Oil And Condensate In Shallower Zones And Oil In Deeper Zones. Preliminary Formation Evaluation Data Indicate The Potential For Prolific Oil Wells. Additionally, The Size Of The Stratigraphic Resource, As Defined By The 3D Seismic Image, Suggests A Substantial Resource.”
“Block 58 Covers 1.4 Million Acres And Offers Significant Potential Beyond The Discovery At Maka Central. We Have Identified At Least Seven Distinct Play Types And More Than 50 Prospects In The Thermally Mature Play Fairway. In Partnership With Total, We Expect To Advance Both Exploration And Development Of Discoveries In The Adjacencies,” Christmann Stated.

In A Separate Statement On Tuesday, Total Confirmed A Material Oil Discovery With The Maka Central-1 Well In Block 58 Off The Coast Of Suriname, In Trend With The Prolific Discoveries In The Adjacent Stabroek Block In Guyana.
Kevin McLachlan, Senior Vice President Of Exploration At Total, Said: “We Are Very Pleased With This First Significant Oil Discovery Made Shortly After Our Entry Into Block 58. The Result Is Very Encouraging And Proves The Extent Of The World-Class Prolific Cretaceous Oil In The Waters Of Suriname.”
McLachlan Added: “We Are Optimistic About The Large Remaining Potential Of The Area Yet To Be Discovered And Are Testing Several Other Prospects In The Same Block”.
