New Well Cost Savings

Theta Difference

Failing to design an optimized pumping system for a new well is often one of the most costly mistakes that a well operator can make. With drastic differences in the cost of pumping units, overestimating the size of the unit needed for optimal production can lead to severe overspending on the upfront costs associated with a well, as well as unnecassary ongoing electricity costs. Below are two cases in which Theta’s software was able to find a cheaper, but equally effective, pumping system for a new well installation:

In these cases, Theta was able to find signficantly cheaper pumping units and rod string alternatives that would allow for the same production. While actual figures may vary on current market rates for this equipment, savings in the $10,000 range per well would be expected. For large operations, the use of Theta’s software could lead to savings of over half a million dollars, before production even begins.

POST-INSTALLATION WELL OPTIMIZATION

Beyond the significant cost savings associated with new well installations, Theta also provides well operators guidance on how to make their pre-existing wells more efficient. These suggestions are reported in easy-to-understand plain English, and leverage advanced predictive algorithms to provide accurate estimations of how a well’s performace will be affected. Below is a case that illustrates how signficant these savings can be:

The boxes above represent the before and after values for many key

production metrics. The left represents the hypothetical pumping

system’s current data, and the right displays expected values once the

software suite’s suggestions have been made.

The torque analysis and electricity consumption data between

the current and proposed pumping system shows a significant

improvement in both categories. The differences reflect significant

power savings, and a drastic reduction in pump motor maintenance

and potential downtimes.

The rod string analysis between the existing and optimized pump system

shows a notable reduction in the stress placed on the rods during

operation. Due to the fact that the forces applied to these rods causes

exponentially more severe product degradation as stress loads increase,

this greatly enhances rod life.

Notable Improvements:

• A near 2% increase in daily production

• An effective 16% increase in system efficency

• An effective 22% increase in unit structure loading

• Structure loading well below capacity (86%) while utilizing a smaller

pumping unit

Notable Improvements:

• An 37% reduction in pump electricity costs

• An effective 14.5% reduction in gearbox loading

• A $0.04 reduction in power cost per barrel

• Substantial immeasurable maintenance and equipment

replacement costs

Notable Improvements:

• A drastically reduced stress load percentage on all of the in-system

rods that are subject to reduction

• Longer rod life and a lessened chance of failure reduce potential

pump maintence, equipment costs, and downtimes
