1 * Formed in 2003, Payzone Surveying has progressed from developing the original v1.1.1 of our software package and running extensive field trials. Formed in 2003, Payzone Surveying has progressed from developing the original v1.1.1 of our software package and running extensive field trials. To the most recent v1.1.2, offers a complete tvd analysis package, field proven delivering consistent accurate data. With multiple station entries, Hardness conversion factors, and inclination accumulation compensation. To the most recent v1.1.2, offers a complete tvd analysis package, field proven delivering consistent accurate data. With multiple station entries, Hardness conversion factors, and inclination accumulation compensation. Based in Dubai, we are ideally situated to offer complete 24/7 support for your Geo-Steering, well placement, surveying QC/QA.

Our aim is to provide a single Definitive TVD datum, removing the current potential confusion between Our aim is to provide a single Definitive TVD datum, removing the current potential confusion between MWD static surveys / continuous MWD data / Inc At Bit data MWD static surveys / continuous MWD data / Inc At Bit data

2 The MWD picture This is what your lateral really looks like. MWD surveys all record 90degs, TVD identical? The reality is your lateral may already be approaching the upper hard window. Payzone’s ability to isolate and analyze each individual interval, over a traditional 95ft section, re-calculate the resultant wellbore tvd and run the error model comparator to the predicted tvd, All of this is vital to control your lateral within Geo-Steering tolerances This is what your lateral really looks like.

3 For years deviated wells the world over have had to live with the accumulated TVD errors of Mud motor runs, a major problem, trying to determining formation dips, and potential reserves. For years deviated wells the world over have had to live with the accumulated TVD errors of Mud motor runs, a major problem, trying to determining formation dips, and potential reserves. Until now no clear answer existed for a reliable cost effective solution. As more and more wells feature Geo-Steering within tighter TVD windows, greater precision is required to identify zones and place your lateral in the optimum position, and keep it there.

Each transition from slide to rotary is identified and processed using the tech sheet, and cross referenced to an error model. The Incremental increase in rotational build rates, and increased Dog-Leg potential over Oriented intervals, as the well bore inclination increases, is also a feature of v1.1.2 The Incremental increase in rotational build rates, and increased Dog-Leg potential over Oriented intervals, as the well bore inclination increases, is also a feature of v1.1.2 A formation Hardness Factor also refines the Oriented & rotational intervals A formation Hardness Factor also refines the Oriented & rotational intervals Already in this model the lateral tvd has altered 0.52ft in 96 ft MD Already in this model the lateral tvd has altered 0.52ft in 96 ft MD With-out Payzone to recalculate this vital tvd error.

6 Typical Payzone-Surveying® Comparison Chart, With a Tangent interval to 1690ft followed by a build section 1700ft md to 1982ft md followed by a further slow build to Landing. Notice the tvd errors are minimal throughout the tangent, increasing in the build, then reduce again in the final slow build. Note the station 2270ft md. This is a formation change trend reversal, (sudden drop in rotary mode) and the station “flagged” a 0.75 error.
