Colombia’s Moqueta field oil output buoys Gran Tierra

Gran Tierra Energy Inc. has added three appraisal wells to its fourth-quarter program in Moqueta field in Colombia’s Putumayo basin after the Moqueta-11 well tested a combined rate of nearly 1,600 b/d of oil from two zones.

The company said its third-quarter net production averaged 18,900 b/d, 97% oil, in Colombia, 2,800 b/d, 82% oil, in Argentina, and 800 b/d of oil in Brazil. Output was above expectations due to the continued strong reservoir performance by Costayaco field and successful execution of transportation strategies.

Moqueta-11 on the southern flank of the Moqueta structure encountered oil in the T-sandstone and Caballos formations. The well averaged 802 b/d of 27.2° gravity oil with a 0.3% water cut from T-sandstone perforations at 6,812-912 ft measured depth. The well also averaged 756 b/d of 27.4° gravity oil with a 0.3% water cut on a hydraulic jet pump from Caballos perforated at 7,043-7,333 ft MD.

The top of the Villeta T-sandstone is 290 ft lower at Moqueta-11 than the lowest known oil encountered in the field at Moqueta-7 well, suggesting the oil column is 290 ft thicker than previously defined. The gross oil columns are now understood to be 765 ft thick in the Villeta T-sandstone and 960 ft thick in the Caballos.

Results indicate that additional oil potentially exists further down the flank of the Moqueta structure. Moqueta-12, first of the three added appraisal wells, was spudded Sept. 23 and targets a reservoir farther south in a previously untested block 270 ft downdip of the lowest known oil encountered at Moqueta-11.

By yearend, Gran Tierra expects to drill Corunta-1 northeasterly from the Costayaco-17 well pad targeting what is believed to be a downthrown fault block extension west of Moqueta field. Zapotero-1 will target the southeastern part of the Moqueta structure.

Meanwhile, Gran Tierra expects to spud the Miraflor West-1 exploratory well in November on the Guayuyaco block in the Putumayo basin targeting the same Cretaceous sandstone reservoirs encountered at Costayaco and Moqueta oil fields.

On the Llanos-22 block, CEPSA and Gran Tierra expect to reach total depth this month at the Mayalito-1 well that is exploring a shallow prospect and testing deeper hydrocarbon-bearing zones encountered but not tested by the successful Ramiriqui-1 oil discovery well.

The Resilient Oilfield in the Internet of Things World

Tue, Sep 22, 2015

As we hear about the hype surrounding the Internet of Things, the oil and gas industry is questioning what is different than what is already being done. What is new?  Using sensors and connecting devices is nothing new to our mode of business and in many ways the industry exemplifies many principles of an industrial internet of things. How does the Internet of Things impact the oil and gas industry?

Prolific instrumentation and automation digitized the industry and has changed the approach to business models calling for a systems led approach.  Resilient Systems have the ability to adapt to changing circumstances while maintaining their central purpose.  A resilient system, such as Maximo, allows an asset intensive organization to leverage connected devices by merging real-time asset information with other critical asset information and using that information to create a more agile organization.  

Join this webcast, sponsored by IBM, to learn how about Internet of Things capabilities and resilient systems are impacting the landscape of the oil and gas industry.
