Objective
Demonstration of new self penetrating tools in industrial slimhole wells. The tools will be built according to a new and quite original drilling concept : the self penetration concept. A new related manufacturing technology will be implemented. Prototypes, including bits and bit - BHA assembly, will be
i) calibrated on full scale drilling bench
ii) tested in slimhole pilot wells and
iii) used in industrial slimhole wells.
Full scale designs have been selected for manufacturing. Prototypes have been manufactured and have been tested with mixed results.
The first set of full scale test results along with the evaluation of the manufacturing process precision shows that some more emphasis must be put to reduce the number of cutters.
A new set of 9 prototypes have been built and lab tested with exceptional results. These lab tests will be confirmed before a field test.
The project includes five tasks :
Task 1 : Engineering
This task includes i) detailed engineering drawings of the cutters, the complete bit and the link between the bit and the BHA, ii) evaluation of the specifications of the trials to be carried out in tasks 3 and 4.
Task 2 : Purchasing and manufacture
Purchasing of outside components (PDC, carbide) and manufacture of three sets of three self penetrating slimbits (diameter 4 1/2), and a bit-BHA system assembly according to specification of task 1.
Task 3 : Pilot tests
The new self penetrating PDC bits will be calibrated during drilling tests on a full scale bench. The mechanical behaviour of the overall system will be assessed during slimhole pilot tests.
Task 4 : Demonstration
The manufactured and tested equipment will be used in commercial slimhole wells in various formation. Task 5 : Evaluation
This task includes a technical analysis of the performances and the optimal operating parameters of the new drilling system. The gainprovided by this new system and its prospective applications will be evaluated.
