The focus of operations is the Giddings Field section of the Austin Chalk,  two of the Company's wells are located in the Pearsall Field to the southwest.

The Company primarily re-enters, re-completes, and re-works existing wells, but also drills a number of grass-roots wells. Leexus Oil LLC is a Limited Liability Company under Texas law, with 10 full-time employees.


The Company mainly uses primary recovery techniques, with no dependence on secondary recovery and on tertiary recovery.* The Company's holdings include leases where wells have not yet been drilled, wells that are nominal producers that need to be re-drilled horizontally, and wells that have been re-drilled horizontally, and wells that have been re-drilled horizontally that have been stimulated with acid and are now producing at an economic rate. Overall production is about 70% oil and 30% natural gas, which approximates the standard ratio found throughout the industry in Texas and elsewhere.
Oil industry experts generally acknowledge that re-working an established oilfield is a much greater engineering and geological challenge than drilling new wells. In the Austin Chalk, this means placing new casings, drilling more lateral extensions, and using high-pressure water fracturing to clean and enlarge tiny cracks in the limestone formation, sometimes as deep as 15,000 feet below the surface. 

In particular, the Giddings Field has experienced at least two distinct phases: an early period of vertical drilling from the late 1960s through the 1970s, and a renewed push using newly developed horizontal drilling techniques from the late 1980s into the 1990s. Vertical wellbores are only able to extract oil and gas from a small area surrounding the base of the well, while horizontal drilling can penetrate multiple hydrocarbon-bearing zones using a single wellbore.  

Some horizontal wells resemble an upside-down tree, with the vertical wellbore serving as the trunk and two to four long branches, called laterals, that can tap a significantly larger area than a traditional wellbore. A horizontal well can equal the production of three or four vertical wells at a significantly lower cost than drilling those wells individually.

Fluctuations in the price of oil on global commodity markets play a key role in exploration and recovery acivity; industry players such as Leexus Oil are willing to spend more to re-work wells and reach oil trapped in faults and fractures in formations like the Austin Chalk. The Company enjoys a distinct advantage in local knowledge, as Mr. Bennie Jaehne is a Lee County native who first began working as a landman in the 1970s. His expertise has been passed down to his sons and continues to play a key role in the Company's success to this day.

* Secondary recovery involves forcing water into the oilfield through injection wells, and is initiated before or after the natural reservoir drive has been fully depleted. The water sweeps some of the remaining oil in place that would not have been produced using primary recovery alone. The amount of oil produced in secondary recovery depends almost entirely on the properties of a particular oilfield.
Tertiary, or enhanced oil recovery (EOR), includes thermal, chemical, and miscible gas processes and involves injecting substances into the reservoir that are not naturally found there.
Unlike secondary recovery techniques which have been widely used since the early days of the oil industry, EOR recovery was developed over the past 50 years. EOR is only effective for a narrow selection of oilfields and involves substantially higher costs and efforts.
