Apache and Total introduced a major oil discovery on the Maka Central-1 properly drilled offshore Suriname on Block 58. The properly was drilled utilizing the drillship Noble Sam Croft with Apache as operator holding a 50% working curiosity and Total holding a 50% working curiosity.

Maka Central-1 efficiently examined for the presence of hydrocarbons in a number of stacked targets within the higher Cretaceous-aged Campanian and Santonian intervals and encountered each oil and fuel condensate. The formation analysis program included logging-while-drilling and wireline logs, formation pressures, and preliminary core and fluid evaluation. Together with future appraisal wells, this information can be used to quantify the useful resource within the Campanian and Santonian formations.

The shallower Campanian interval comprises 50 meters (164 ft) of internet hydrocarbon-bearing reservoir. Preliminary fluid samples and check outcomes point out gentle oil and fuel condensate with API gravities between 40 and 60 levels.


The deeper Santonian interval comprises 73 meters (240 ft) of internet oil-bearing reservoir. Preliminary fluid samples and assessments outcomes point out API oil gravities between 35 and 45 levels.

The Maka Central-1 additionally focused a 3rd interval, the Turonian, a geologic analogue to grease discoveries offshore West Africa. Prior to reaching this interval, the properly encountered considerably over-pressured, oil-bearing reservoirs within the decrease Santonian, and the choice was made to conclude drilling at roughly 6,300 meters (20,670 ft). The pressures encountered within the decrease Santonian are a optimistic signal for the Turonian and future drilling will check this interval.

“We are more than happy with outcomes from Maka Central-1. The properly proves a working hydrocarbon system within the first two play sorts inside Block 58 and confirms our geologic mannequin with oil and condensate in shallower zones and oil in deeper zones. Preliminary formation analysis information signifies the potential for prolific oil wells. Additionally, the scale of the stratigraphic function, as outlined by Three-D seismic imaging, suggests a considerable useful resource,” mentioned John J. Christmann, Apache CEO and President.

“Block 58 contains 1.four million acres and gives vital potential past the invention at Maka Central. We have recognized a minimum of seven distinct play sorts and greater than 50 prospects throughout the thermally mature play fairway. In partnership with Total, we look ahead to advancing each exploration and improvement of discoveries on the block,” Christmann mentioned.

The Sam Croft will drill the following wells in Block 58, beginning with the Sapakara West prospect. Sapakara West-1, situated roughly 20 kilometers (12 miles) southeast of the Maka Central discovery, will check oil-prone higher Cretaceous targets within the Campanian and Santonian intervals.
