New Drilling Campaign and New Technologies after 10 Years Without Drilling improve Performance in La Ceiba field

Abstract

The history of La Ceiba field began 10 years ago when six exploration wells were drilled to assess the potential of this field. The wells were drilled with several incidents of stuck pipe and the resulting necessary side-tracks to reach the final depth. Until last year no further attempt had been made to drill in this field. With little information available from the exploration wells concerning drilling practices, the drilling campaign began with the goal of improving the previous performance, making the drilling of the complete wells faster and safer than in the previous drilling. An engineering process was begun to find the best drilling solution for the field, starting with proven technologies such as positive displacement motors (PDM) and drill bits used in similar fields; however, this methods alone were not sufficient to meet the challenges of the field. New technologies were used for the different challenges and applications through coordinated work between the drilling engineering departments of the different parties involved in this field and using all the information available in the drill bit selection database, including logs and stability data for the tools selected to drill each phase of the wells. With evolution of the learning curve, drilling progressed from initial drilling involving 12 runs with time-consuming trips to surface to change either the drill bit or PDM, to drilling the same interval in 5 runs with the time on bottom increasing compare to previous experiences due to the introduction of tools more suitable to the environment requirements a rotary steerable systems (RSS) in combination with a specially designed drill bit. Problems commonly faced in the upper sections were, the trajectory was not strictly followed, were solved with the introduction of the RSS in this section; use of the tool saved 10 days of rig time and set a bench mark for the field and similar wells in western Venezuela. The development of this field shows that by solving the issues related to the well depth, temperature and constraints well design for these wells in western Venezuela, it will be possible to reach the oil reserves, at the same time decreasing the time spent in the drilling process.

Developing a framework for youth empowerment to prevent smoking behavior in a rural setting: study protocol for a participatory action research

“…The diagnosing phase focuses on identifying and defining the problem and collecting data for further investigation (Coghlan and Brannick, 2014;Susman and Evered, 1978). This stage involves conducting dialogue activities with stakeholders in the program to determine the themes of the planned activities to be conducted.…”

“…Planning action involves considering courses of action based on initial diagnosis (Coghlan and Brannick, 2014;Susman and Evered, 1978). At this stage, several meetings were held to share ideas and experiences as well as learn techniques, models and experiences.…”

“…Taking action is implemented according to the specified plan (Coghlan and Brannick, 2014;Susman and Evered, 1978). This section describes the taking action of some programs that have been mutually agreed between the participants and the facilitator.…”

“…Evaluation is assessing the actions and their consequences, documenting and interpreting cycle outcomes to aid improvement (Coghlan and Brannick, 2014;Susman and Evered, 1978). At this stage, evaluation and visual representation are needed at the group level, namely the evaluation of the youth empowerment domain, which aims to find out the extent of the process and implementation of youth empowerment in smoking prevention programs.…”
