Radial Drilling Optimization

Radial Drilling Optimization

With conventional lateral drilling the transition from drilling vertically to horizontal drilling may take 200 feet or more and take days to accomplish. Verdisys with its patented technology can make this transition in 2 feet instead of the industry normal of 200 feet and do it in a matter of minutes not hours. This enables Verdisys to be extremely precise in targeting specific pay zones for a significant enhancement to the production of the well.

Many of the nation's old oil and gas fields contain new infield reservoir compartments and bypassed reservoirs that have never been economical to produce. Lateral drilling will make it economically viable to produce from those reservoirs for the first time.

Verdisys lateral drilling techniques utilize patented technology in the areas of the design and manufacture of the Deflecting Boot and the process of high pressure water jet drilling.

Verdisys lateral drilling works on both new and existing wells. Where lateral drilling performs best is on depleted wells that are ready to be capped because they are no longer economically viable. This negates the continual need for new explorations and drilling. Fields that are ready to be deserted and have about 80% of the reserves still in ground can be maximized to pull another large portion of the ground reserves.

Lateral drilling can drastically expand the production area within a given field. An average well will pull petroleum from an area of up to 120 feet from the well bore. However, each lateral extends up to 300 feet from the well bore, thus increasing the area of production several fold.

Traditional well bore configuration pulling from 120 feet equates to a total volume of pay zone of 271,296 cubic feet. Each lateral of 300 feet will pull from over 360,000 cubic feet. Thats 1,440,000 cubic feet on four laterals.

Benefits of Radial Drilling Optimization

Increase production rate and recoverable reserves from marginal wells
Improves injection rates in water disposal/injection wells
Allows directional treatment of wells e.g. acid, steam, CO2, etc
Allows multi-layer application in thicker reservoir zones
Techniques most effective on old low productivity wells
No need for large, expensive rotary rigs
No mud pits that can damage the environment.
No casing milling equipment necessary
No additional stimulation required
No logging expense required
No need to change well-bore configuration

Well Stimulation

In addition to Radial Drilling Optimization, Verdisys also offers peripheral well stimulation. The injection of liquid CO2 into the well after the lateral drill is completed has two major benefits: 1) CO2 acts as a detergent to clean petroleum bearing strata and 2) CO2 raises the down-hole pressure in the well, thus forcing more petroleum out of the petroleum bearing strata.

As an added enhancement Verdisys provides C02 injection into the well after the lateral drilling process is completed. This provides a 1000 to 1 ratio of expansion in the zone to provide added drive pressure to energy production. This process works extremely well in wells that have lost drive pressure but still have a significant amount of oil and gas information

Petroleum Enhancement Solutions

Lateral or horizontal drilling has been around since the early 1980's and the average cost of this service on an existing well is approximately $100,000 - $250,000. for the typical onshore well. Verdisys through its technology can perform Radial Drilling Optimization with very similar results at a fraction of the cost. This along with peripheral well stimulation services, will forge significant revenue returns to Verdisys customers.

Verdisys petroleum enhancement solutions include a family of Radial Drilling Optimization technologies centered around the use of fluid-jet drilling techniques for secondary recovery of reserves on existing wells. These technologies allow a series of laterals to be drilled horizontally out into the pay zone of an existing well at various depths selected by the Oil & Gas Operator.

Lateral drilling services target the existing infrastructure of oil and gas wells in North America 5800 feet deep and shallower. With the use of Radial Drilling Optimization technologies, reserves that otherwise would have remained beyond the economics of conventional technologies can now be recovered efficiently and economically. In some cases production recovers to a point at or exceeding that of the wells initial production. This enables penetrating farther into the strata and costs are an order of magnitude less expensive than current conventional lateral drilling techniques.

In addition to Radial Drilling Optimization, Verdisys also offers peripheral well stimulation services. The injection of liquid CO2 into the well after the lateral drill is completed has two major benefits: 1) CO2 acts as a detergent to clean petroleum bearing strata and 2) CO2 raises the down-hole pressure in the well, thus forcing more petroleum out of the petroleum bearing strata.

Features of Lateral Drill Include:

The lateral drill is portable and easily moved from well to well. Setup in less than 4 hours
The lateral drilling process is fast. Average time the rig is on the well is only two days
Cuts a two (2) inch diameter hole horizontally up to 300 feet from the well bore
Lateral drill can jet 4 channels in any direction
