Abstract: As one of the effective ways to improve the utilization of reservoir, horizontal well technology has been widely used domestic and abroad. Drilling geological tracking is the key factor of achieving the purpose of drilling horizontal wells and good results. In this paper, the technical difficulties in the process of tracking have been analyzed, and the measures have been put forward. Considering the characteristics of the complex structure and the variable reservoir changes in Dagang oilfield, on the basis of practical tracking experiences on various horizontal wells, the method of calculating the best landing deviation.........

Abstract: Geology and radiometric survey of Ghumchi (Michika) part of Hawal massif NE Nigerian basement complex has been carried out, this lies at Longitude 13o 23I 00II to 13o 30I 00II E, Latitude 10o 30I 00II to 10o 41I 00II N. The area is underlain by Basalt, Porphyritic Biotite Granite, Medium to coarse grained Granite, Migmatite Granite, Banded Gniess and, crush braccia catalasite and Mylonite along a fault zone. The dominant rock type in the mapped area is Porphyritic Biotite Granite and Migmatite Granite. The radiometric survey showed a high radiometric anomaly, which is observed Northward of the study area at a fault zone associated with Mylonite and Cataclasite.........

Abstract: Under the existing calculation conditions, improving reservoir simulation computing speed is of great significance, and it is a hot research issue in the world. At present, although the proper orthogonal decomposition (POD) method can be applied to the nonlinear reservoir simulation system, the acceleration is limited, because in the simulation process, each iteration step requires the construction and projection of the full order Jacobian matrix. Trajectory piecewise-linear.........
